FOREWORD
Dear teacher,
Rwanda Basic Education Board is honoured to present to you the Primary two Science
and Elementary Technology Teacher's Guide which serves as a guide to
competence-based teaching and learning to ensure consistency and coherence in the
learning of Science and Elementary Technology subject. The Rwandan educational
philosophy is to ensure that learners achieve full potential at every level of education
which will prepare them to be well integrated in society and exploit employment
opportunities.
In line with efforts to improve the quality of education, the government of Rwanda
emphasizes the importance of aligning teaching and learning materials with the syllabus
to facilitate their learning process. Many factors influence what they learn, how well they
learn and the competences they acquire. Those factors include the relevance of the specific
content, the quality of teacher’s pedagogical approaches, the assessment strategies and the
instructional materials available. We paid special attention to the activities that facilitate
the learning process in which learners can develop ideas and make new discoveries during
concrete activities carried out individually or with peers. With the help of the teacher,
learners will gain appropriate skills and be able to apply what they have learnt in real life
situations. Hence, they will be able to develop certain values and attitudes allowing them
to make a difference not only to their own life but also tothe nation.
This is in contrast to traditional learning theories which view learning mainly as a process
of acquiring knowledge from the more knowledgeable person who is mostly the teacher.
In competence-based curriculum, learning is considered as a process of active building
and developing of knowledgeand understanding, skills and values and attitude by the
learners whereconcepts are mainly introduced by an activity or situation that helpsthe
learners to construct knowledge, develop skills and acquire positive attitudes and values.
In addition, such active learning engages learners in doing things and thinking about the
things they are doing and they are encouraged to bring their own real experiences and
knowledge into the learning processes. Inview of this, your role is to:
 Plan your lessons and prepare appropriate teaching and learning materials.
 Organize group discussions for learners considering the importance of social
constructivism suggesting that learning occurs more effectively when the learners
work collaboratively with more knowledgeable and experienced people.
 Engage learners through active learning methods such as inquirymethods, group
3
discussions, research, investigative activities and group and individual work
activities.
 Provide supervised opportunities for learners to develop different competences by giving
tasks which enhance critical thinking, problem solving, research, creativity and
innovation, communication and cooperation.
 Support and facilitate the learning process by valuing learners’ contributions in the
class activities.
 Guide learners towards the harmonization of their findings.
 Encourage individual, peer and group evaluation of the work done in the classroom and use
appropriate competence-based assessment approaches and methods.
To facilitate you in your teaching activities, the content of this teacher’s guide is self-
explanatory so that you can easily use it. It is divided in 3 parts:
The part 1: Explains the structure of this Teacher’s guide and gives you the
methodological guidance;
The part 2: Gives the sample lesson plans as reference for your lesson planning process;
The part 3: Provides the teaching guidance for each concept given in the Pupil’s book.
Even though this teacher’s guide contains the answers to all activities given in the
student’s book, you are requested to work through each question and activity before
judging learner’s findings.
I wish to sincerely appreciate all people who contributed towards the development,
translation and adaptation of this teacher’s guide, particularly REB staff who organized
the whole process from its inception. Special gratitude goes to translators, illustrators
and designers who diligently worked to successful completion of this teacher’s guide. Any
comment or contribution would be welcome for the improvement of this teacher’s
guide for the next edition.

PART I: GENERAL INTRODUCTION
1.0. About the Teacher’s guide
This book is a Teacher’s guide for Primary Three Science and ElementaryTechnology
subject. It is designed to accompany Pupil’s book and intends to help teachers in the
implementation of competence basedcurriculum specifically Science and Elementary
Technology syllabus.
As the name says, it is a guide that teachers can refer to when preparing their lessons.
Teachers may prefer to adopt the guidance provided but they are also expected to be
more creative and considertheir specific classes’ contexts and prepare accordingly.
1.1. The structure of the guide
This section presents the overall structure, the unit and sub-headingstructure to help
teachers to understand the different sections of thisguide and what they will find in
each section.
Overall structure
The whole guide has three main parts as follows:
Part I: General Introduction
This part provides general guidance on how to develop the generic competences, how to
integrate cross cutting issues, how to cater for students with special educational needs, active
methods and techniques of teaching Science and Elementary Technology and guidance on
assessment.
Part II: Sample lesson plan
This part provides a sample lesson plan, developed and designed to help the teacher develop
their own lesson plans.
Part III: Unit development
This is the core part of the guide. Each unit is developed following thestructure below:
Each unit is made of the following sections:
- Unit title: from the syllabus
- Key unit competence: from the syllabus
- Prerequisites (knowledge, skills, attitudes and values)
6
This section indicates knowledge, skills and attitudes required for the success of the unit.
The competence-based approach calls for connections between units/topics within a subject
and interconnections between different subjects. The teacher will find an indication of those
prerequisites and guidance on how to establish connections.
- Cross-cutting issues to be addressed
This section suggests cross cutting issues that can be integrated depending on the unit content.
It provides guidance on how to comeup with the integration of the issue. Note that the issue
indicated is a suggestion; teachers are free to take or add another cross-cutting issuetaking into
consideration the learning environment.
- List of lessons
This section presents in a table the list of suggested lessons, lesson objectives copied or adapted
from the syllabus and duration for each lesson.
- Teaching approach for each lesson
In this section, each lesson is developed by describing how it will be conducted in classroom.
Note that it is a proposal which leaves the room to the teacher of adapting the lesson to the
context of the class and school environment. Each lesson development shows the lesson
objectives, teaching and learning materials, teaching and learning activities, conclusion of the
lesson and assessment of the lesson.
- Additional information for the teacher
This part gives the teacher additional content and advanced knowledge onthe unit to be taught.
Remember that the teacher must have more knowledgeand understanding beyond the content or
topic in the syllabus and Pupil’s book.
- Answers to End of unit assessment
This part provides answers or guidance to questions of the end of unit assessment in the Pupil’s
book and suggests additional questions and related answers to assess the key unit competence.
- Additional activities (remedial, consolidation and extended activities)
The purpose of these activities is to accommodate each learner (slow, average and gifted) based
on end of unit assessment results.
7
Structure of each lesson
Each lesson is made of the following sections:
Lesson title 1: ……………
- Lesson objectives
- Teaching and learning resources
This section suggests the teaching aids or other resources needed in line with the activities to
achieve the learning objectives. Teachers are encouraged to replace the suggested teaching
aids by the available ones in their respective schools and based on learning environment.
- Teaching and Learning activities
This section provides a short description of the methodology and any important aspect to
consider. It provides also answers to learningactivities with cross reference to Pupil’s book.
- Assessment and Conclusion
This provides guidance on how to conduct assessment and support learners to make a
conclusion or summary of what they learned.
Note: The guide ends with references.
1.2. Methodological guidance
1.2.1. Developing competences
Since 2015, Rwanda shifted from a knowledge based to a competence basedcurriculum for
pre-primary, primary and general secondary education. For TTCs, it is in 2019 that the
competence based curriculum was embraced. Thiscalled for changing the way of learning by
shifting from teacher centered to a learner centered approach. Teachers are not only
responsible for knowledge transfer but also for fostering pupil’s learning achievement, and
creating safe and supportive learning environment. It implies also that a learner has to
demonstrate what he/she is able to do using the knowledge, skills, values and attitudes acquired
in a given situation.
The competence-based curriculum employs an approach of teaching and learning based on
discrete skills rather than dwelling on only knowledge or the cognitive domain of learning.
It focuses on what learners can do rather than what they know. Learners develop basic
competences through specific subject unit competences with specific learning objectives broken down
into knowledge, skills and attitudes. These competences are developed through learning
activities disseminated in learner-centered rather than the traditional instructive approach. The
learner is evaluated against set standards to achieve before moving on.
8
In addition to specific subject competences, learners also develop generic competences which are
transferable throughout a range of learning areas and situations in life.
Below are examples of how generic competences can be developed in Scienceand Elementary
Technology:
Generic competence Examples of activities that develop genericcompetences
Critical thinking These activities require learners to think critically about subject
content. These may include:
Work in groups in different ways e.g. taking turns,listening, taking
decisions,
Observe and analyse. Example: mark out areas in the school and get
different groups to record livingthings like insects, people, animals,
birds
Discuss and give scientific reasons of phenomenon commonly known
like sun shining, raining, changing colours for plants, e.t.c.
Observe, record, interpret data recorded during
experiments
Identify and use the applications of Science and Elementary
Technology concepts to solve problems of life and society
Research and Problem Research using internet or books from the library
solving
Design a project for making toys and materials
Innovation and creativity Create an experiment procedure to prove a point

Making practice in different units
- Conduct experiments with objectives, methodology,observations,
results, conclusions
- Identify local problems and ways to resolve them
9
Cooperation, Personal and Work in Pairs
Interpersonal
Small group work
management and life
skills Large group work
Communication Telling a story related to the lesson of SET needed to be studied

Presenting ideas verbally or in writing
Reading a text related to SET
Lifelong learning Take initiative to update knowledge and skills with minimum
external support
Cope with the evolution of knowledge and technology advances for
personal fulfilment
Seek out acquaintances more knowledgeable in areas that need
personal improvement and development
Exploit all opportunities available to improve knowledge and skills
in SET.
1.2.2. Addressing cross cutting issues

Among the changes in the competence based curriculum is the integration of cross cutting
issues as an integral part of the teaching/learning process as they relate to and must be
considered within all subjects to be appropriately addressed. The eight cross cutting
issues identified inthe national curriculum framework are: genocide studies, environment
and sustainability, gender, Comprehensive Sexuality Education (CSE), Peace and Values
Education, Financial Education, standardization Culture and Inclusive Education.
Some cross cutting issues may seem specific to particular learning areas or subjects but
the teacher needs to address all of them whenever an opportunity arises. In addition,
student should always be given an opportunity during the learning process to address these
cross cutting issues both within and out of the classroom so as to progressively develop
related attitudes and values.
Below are examples on how crosscutting issues can be addressed in Science and Elementary
Technology:
10
Cross-cutting Examples on how to integrate the cross-cutting issues
issues
Inclusive education Involve all learners in all activities without any bias.
Eg: Allow a learner with physical disability (using wheelchair) to
take notes or lead the team during a task or an experiment.
Gender Involve both girls and boys in all activities: No activity is reserved only
to girls or boys.
Teacher should ensure equal participation of both girls and boys
during activities as well as during cleaning activities after practical
tasks.
Peace and Values During group activities, the teacher will encourage learners to help
Education each other. During all teaching and learning activities, texts and examples
used by the teacher should reflect promotion of peace and values among
them at school and with others in society.
Standardizationculture - Some lessons involve carrying out practical tasks. Instructions

should be clear for learners to always check if they are using
appropriate materials.
- Through making quality work/objects which are attractive to the
community.
Environment and In order to avoid the environment pollution, before, during or after
sustainability practical tasks, learners should avoid throwing wastes anywhere;
special places or appropriate containers should be used.
During field visits, learners should be reminded of not damaging or
destroying environment components or of not throwing wastes in
environment.
Financial Education When making toys and objects for example, learners are encouraged
to use well the resources by using the quantities that are just required.
Using materials, tools and materials in proper way for safeguarding
their durability
Making different objects that can be sold.
11
1.2.3. Attention to special educational needs specific to teaching and learning SET
subject
In the classroom, pupils learn in different way depending to their learning pace,needs or any
other special problem they might have. However, the teacher has the responsibility to know how
to adopt his/her methodologies and approaches in order to meet the learning needs of each pupil
in the classroom. Also teachermust understand that learners with special needs need to be
taught differently or need some accommodations to enhance the learning environment. This
will be done depending on the unit and the nature of the lesson.
In order to create a well-rounded learning atmosphere, teacher needs to:
• Remember that pupils learn in different ways so they have to offer a variety of activities
(e.g. role-play, music and singing, word games and quizzes, and outdoor activities).
• Maintain an organized classroom and limits distraction. This will help learners with
special needs to stay on track during lesson and follow instructions easily.
• Vary the pace of teaching to meet the needs of each learner. Some learners process
information and learn more slowly than others.
• Break down instructions into smaller, manageable tasks. Learners with special needs
often have difficulty understanding wordy or several instructions at once. It is better to use
simple, concrete sentences in order to facilitate them understand what you are asking.
• Use clear consistent language to explain the meaning (and demonstrate or show
pictures) if you introduce new words or concepts.
• Make full use of facial expressions, gestures and body language.
• Pair a learner who has a disability with a friend. Let them do things together and learn
from each other. Make sure the friend is not over protective and does not do everything
for the learner. Both learners will benefit from this strategy.
• Use multi-sensory strategies. As all pupils learn in different ways, it is important to
make every lesson as multi-sensory as possible. Pupils with learning disabilities might
have difficulty in one area, while they might excel in another. For example, use both visual
and auditory cues.
Below are general strategies related to each main category of disabilities and how to deal with
every situation that may arise in the classroom. However, the list is not exhaustive because
each learner is unique with different needs and that should be handled differently.
Strategy to help learners with developmental impairment

The teacher should:
• Use simple words and sentences when giving instructions.
• Use real objects that the learner can feel and handle, rather than just working abstractly
12
with pen and paper.
• Break a task down into small steps or learning objectives. The learner should start with
an activity that s/he can do already before moving on to some thing that is more difficult.
• Gradually give the learner less help.
• Let the learner work in the same group with those without disability.
Strategy to help learners with visual impairment

The teacher should:
• Help learners to use their other senses (hearing, touch, smell andtaste) to play
and carry out activities that will promote their learning anddevelopment.
• Use simple, clear and consistent language.
• Use tactile objects to help explain a concept.
• If the learner has some sight problem, ask him/her what they can see. Get information
from parents/caregivers on how the learner manages their remaining sight at home.
• Make sure the learner has a group of friends who are helpful and who allow them to be
as independent as possible.
• Plan activities so that learners work in pairs or groups whenever possible.
Strategy to help learners with hearing impairment

The teacher should:
• Set strategies to help learners with hearing disabilities or communication
• difficulties
• Always get the learners’ attention before you begin to speak.
• Encourage the learners to look at your face.
• Use gestures, body language and facial expressions.
• Use pictures and objects as much as possible.
• Ask the parents/caregivers to show you the signs they use at home for communication.
Use the same signs and encourage other learners to also use them.
• Keep background noise to a minimum.
Strategies to help children with physical disabilities or mobility difficulties

The teacher should:
• Adapt activities so that learners who use wheelchairs or other mobility
• aids, or other learners who have difficulty moving, can participate.
• Ask parents/caregivers to assist with adapting furniture e.g. The height of a table may
need to be changed to make it easier for a learner to reach it or fit their legs or wheelchair
under.
13
• Encourage peer support. Friends can help friends.
• Get advice from parents or a health professional about assistive devices.
1.2.4. Guidance on assessment

Each unit in the Teacher’s guide provides additional activities to help learners achieve the key
unit competence. Results from assessment inform the teacher which learner needs remedial,
consolidation or extension activities. These activities are designed to cater for the needs of all
categories of learners; slow, average and gifted respectively.
Assessment is an integral part of teaching and learning process. The main purpose of
assessment is for improvement. Assessment for learning/ Continuous/ formative assessment
intends to improve learners’ learning and Teacher’s teaching whereas assessment of
learning/summative assessment intends to improve the entire school’s performance and
education system in general.
Continuous/ formative assessment
It is an ongoing process that arises out of interaction during teaching and learning process. It
includes lesson evaluation and end of sub unit assessment. This formative assessment plays a
big role in teaching and learning process. The teacher should encourage individual, peer and
group evaluation of the work done in the classroom and uses appropriate competence-based
assessment approaches and methods.
In Primary Three, formative assessment principle is applied through application activities that
are planned in each lesson to ensure that lesson objectives are achieved before moving on. At
the end of each unit, the end of unit assessmentis formative when it is done to give information
on the progress of learners and from there decide what adjustments need to be done.
Assessment standards are taken into consideration when setting tasks.
Summative assessment
The assessment done at the end of the term, end of year, is considered as summative. The
teacher, school and parents are informed on the achievementof educational objectives and think
of improvement strategies. There is also end of level/ cycle assessment in form of national
examinations.
1.2.5. Pupils’ learning styles and strategies to conduct teaching and learning process
14
There are different teaching styles and techniques that should be catered for. The selection of
teaching method should be done with the greatest care and some of the factors to be considered
are: the uniqueness of subjects, the type of lessons, the particular learning objectives to be
achieved, the allocated time to achieve the objective, available instructional materials, the
physical/sitting arrangement of the classroom, individual learner’s needs, abilities and learning
styles.
There are mainly four different learning styles as explained below:
a) Active and reflective learners
Active learners tend to retain and understand information best by doing something active with
it, discussing or applying it or explaining it to others. Reflective learners prefer to think about it quietly
first.
b) Sensing and intuitive learners
Sensing learners tend to like learning facts while intuitive learners often preferdiscovering
possibilities and relationships. Sensors often like solving problems by well-established
methods and dislike complications and surprises; intuitive learners like innovation and dislike
repetition.
c) Visual and verbal learners
Visual learners remember best what they see (pictures, diagrams, flow charts, time lines, films,
demonstrations, etc.); verbal learners get more out of words (written and spoken explanations).
d) Sequential and global learners
Sequential learners tend to gain understanding in linear steps, with each step following
logically from the previous one. Global learners tend to learn in large jumps, absorbing
material almost randomly without seeing connections, and then suddenly “getting it.”
1.2.6. Teaching methods and techniques that promote theactive learning

The different learning styles mentioned above can be catered for, if the teacher uses active
learning whereby learners are really engaged in the learning process.
What is Active learning?
Active learning is a pedagogical approach that engages students in doing things and thinking
about the things they are doing. In active learning, learners are encouraged to bring their own
experience and knowledge into the learning process.
The role of the teacher in active learning
15
- The teacher engages learners through active learning methods such as inquiry methods,
group discussions, research, investigative activities and group and individual work
activities.
- He/she encourages individual, peer and group evaluation of the work done in the classroom
and uses appropriate competence-based assessment approaches and methods.
- He provides supervised opportunities for learners to develop different competences by
giving tasks which enhance critical thinking, problem solving, research, creativity and
innovation, communication and cooperation.
- Teacher supports and facilitates the learning process by valuing learners’contributions in the
class activities.
The role of learners in active learning

Learners are key in the active learning process. They are not empty vessels to fill but people with
ideas, capacity and skills to build on for effective learning.
A learner engaged in active learning:
- Communicates and shares relevant information with other learners through presentations,
discussions, group work and other learner- centred activities (role play, case studies,
project work, research and investigation).
- Actively participates and takes responsibility for their own learning.
- Develops knowledge and skills in active ways.
- Carries out research/investigation by consulting print/online documents and resourceful
people, and presents their findings.
- Ensures the effective contribution of each group member in assigned tasks through clear
explanation and arguments, critical thinking, responsibility and confidence in public speaking.
- Draws conclusions based on the findings from the learning activities.
Some active techniques that can be used in Science and Elementary Technology
The teaching methods strongly emphasised in the competence Based Curriculum (CBC) are
active methods. Below are some active techniques that apply in sciences:
A. Practical work/ experiments:
Many of the activities suggested in the Science and Elementary Technology curriculum as well
as in the Pupil’s book are practical work or experiments.
Practical work is vital in learning Science and Elementary Technology; this method gives
the learner the opportunity to implement a series of activities and leads to the development of
both cognitive and hands-on skills. The experiments and questions given should target the
development of the following skills in learners: observation, recording and report writing,
16
manipulation, measuring, planning and designing. Most of experiments or practical activities
suggested in the syllabus of SET are developed in step by step guidance in a booklet called
“SET Practical activities user guide” to be used while facilitating such practical activities.
A practical lesson/Experiment is done in three main stages:
• Preparation of practical lesson/ experiment: Checking materials to ensure they are
available and in a good state; try the task before the lesson; think of safety rules and give
clear instructions.
• Performance of practical lesson/ experiment: Sitting or standing arrangement of
learners; introduction of the experiment: aims and objectives; setting up the materials;
performing the experiment; write and record the data.
• Discussion: Observations and interpreting data; make generalisations and assignment: writing out
the experiment report and further practice and research.
In some cases, demonstration by the teacher is recommended when for examplethe experiment
requires the use of sophisticated materials or very expensive materials or when safety is a
major factor like dangerous experiments and it needs specific skills to be learnt first.
In case your school does not have enough science kit materials, experiments can be done in
groups but make sure every learner participates.
B. Project work
Science and Elementary Technology teachers are encouraged to sample and prepare project
works and engage their learners in, as many as possible. Learners in groups or individually,
are engaged in a self-directed work for an extended period of time to investigate and respond
to a complex question, problem, or challenge. Projects are based on real-world problems that
capture learners’ interest. This technique develops higher order thinking as the learnersacquire
and apply new knowledge in a problem-solving context.
C. Field trip
One of the main aims of teaching Science and Elementary Technology inRwanda is to apply its
knowledge for development. To achieve this aim we need to show to learners the relationship
between classroom science lessons and applied sciences. This helps them see the link between
science principles and technological applications.
To be successful, the field visit should be well prepared and well exploited after the visit:
Before the visit, the teacher and learners:
- agree on aims and objectives
- gather relevant information prior to the visit
17
- brainstorm on key questions and share responsibilities
- discuss materials needed and other logistical and administrative issues
- discuss and agree on accepted behaviours during the visit
- Visit the area before the trip if possible to get familiar with the place
After the visit

When learners come back from trip, the teacher should plan for follow-up. The follow-up
should allow learners to share experiences and relate them to the prior science knowledge.
Alternate Teaching Approach
The 5Es
This "5Es" is a constructivist approach based on the idea that learners learn best when they
participate in activities that give them opportunities to work things out for themselves. As
the names suggests, there are five phases: engage, explore,explain, elaborate and evaluate.
1. Engage
In this phase:
• Teachers engage learners in activities that capture their interests and
• stimulate curiosity,
• Learners raise questions,
• Teachers verify learners’ prior understandings of the topic,
• Learners compare ideas.
2. Explore
In this phase learners undertake hands-on activities where they:
• Experience the phenomenon or concept,
• Explore the questions they have raised, test their ideas and solve problems.
3. Explain
Only after learners have had opportunities to explore, they have opportunities to:
• Compare their ideas with scientific explanations,
• Use scientific terminology,
• Construct explanations that can be justified using information collected.
4. Elaborate
In this phase learners have opportunities to:
18
• Apply what they have learnt to new contexts,
• Develop a deeper understanding of the problem or phenomenon as they discuss and
compare ideas.
5. Evaluate
In this phase learners and the teacher:
• Look for evidence of changes in learners’ ideas, beliefs and skills,
• Evaluate what learners know and can do.

Main steps for a lesson in active learning approach

All the principles and characteristics of the active learning process highlighted above are reflected
in steps of a lesson as displayed below. Generally, the lesson is divided into three main parts whereby
each one is divided into smaller steps to make sure that learners are involved in the learning
process. Below are those main parts and their small steps:
1) Introduction
Introduction is a part where the teacher makes connection between the current and previous lesson
through appropriate technique. The teacher opens short discussions to encourage learners to think
about the previous learning experience and connect it with the current instructional objective.
The teacher reviews the prior knowledge, skills and attitudes which have a link with the new
concepts to create good foundation and logical sequencing.
2) Development of the new lesson
The development of a lesson that introduces a new concept will go through the following small
steps: discovery activities, presentation of learners’ findings, exploitation, synthesis/summary
and exercises/application activities, explained below:
 Discovery activity
Step 1
- The teacher discusses convincingly with learners to take responsibility of their learning
- He/she distributes the task/activity and gives instructions related to the task (working
in groups, pairs, or individual to instigate collaborative learning, to discover what is to be
learnt.)
Step 2
- The teacher allows the learners to work collaboratively on the task.
- During this period the teacher refrains to intervene directly on the task.
21
- He/she then monitors how the learners are progressing towards thetask to be done and
boost those who are still behind (but without communicating to them)
 Presentation of learners’ findings
- In this section, the teacher invites representatives of groups to present the learners’
productions/findings.
- After three/four or an acceptable number of presentations, the teacher decides to engage the
class into discussion about the learners’ findings. .
- Discussion on the learners’ findings. The teacher asks the learners to evaluate the findings
citing the ones that are correct, incomplete or false.
- Then the teacher judges the logic of the learners’ findings, corrects those which are false,
completes those which are incomplete, and confirms those which are correct.
 Institutionalization (summary/conclusion/ and examples)
The teacher summarises the learnt content and gives examples which illustrate the learnt content.
 Exercises/Application activities
- Exercises of applying processes and products/objects related to covered unit/sub-unit
- Exercises in real life contexts
- Teacher guides learners to make the connection of what they learntto real life situations.
At this level, the role of teacher is to monitor the fixation of process and product/object being
learnt.
3) Assessment
In this step the teacher asks some questions to assess achievement of instructional objective.
During assessment activity, learners work individually on the task/activity. The teacher avoids
intervening directly. In fact, results from this assessment inform the teacher on next steps for the
whole class andindividuals. In some cases, the teacher can end with a homework assignment.

PART III. UNITS DEVELOPMENT
Unit 1: TOOLS AND MATERIALS USED AT HOME AND AT SCHOOL
1.1 . Key unit competence

To use and keep properly tools used at home and at school
1.2 . Prerequisite
For a learner to understand easily this unit, it is necessary for a learner to have prior knowledge
on the names of tools and materials used at home and schools very well.
1.3. Introductory activity and guidance
Guidance on the introductory activity:
- Ask learners to look at the pictures on page 1 of the student’s book and observe what

Most important external elements of a computer
Below is a list of the most well-known and important external elements of a computer.
1- Case
The computer case or box is the device on which the computer's motherboard is installed.
Without this, the computer could not function. There are vertical and horizontal boxes.
2- Monitor
The monitor is a peripheral information output device. It is a peripheral element since it allows
the communication between the user and the equipment. It is output because it materializes on
the screen the information that is processed in the computer.
The monitor operates with a series of dots that are illuminated according to a binary encoding
matrix. To control this system, a video card, which is an internal part of the computer, is used.
3- Keyboard
The keyboard is the computer's most important peripheral input device. It is input because it
allows you to enter information into the computer.
This device consists of a series of keys and a microprocessor that transmits the information from
the keyboard to the central processor of the computer.
Desktops typically have 101-key keyboards, but laptops in some cases have fewer.
Some of the most important keys of these peripheral devices are:
- Alphabetical, in which the letters are arranged.
- The number keys.
- The function keys (F1, F2... F12), which allow to execute operations of easier way.
53
- Navigation keys, that allow to move in the four directions.
- Escape key.
- Control keys.
- Tabulation.
- Caps lock.
- Shift, which shows the secondary functions of certain keys.
- Alt, which shows other additional functions of the keys.
- Space bar.
- Start, back, forward and end keys, which allow you to scroll up and down a page.
- Enter key.
- Clear key.
4- Mouse
After the keyboard, the mouse is the second most relevant input device on a computer. This
reduces the use of the keyboard and makes navigation faster.
At first, the mouse was endowed with a sphere at the bottom. As he moved this sphere against
the desk, he moved the mouse cursor on the computer screen.
Subsequently, this system was displaced by infrared technology, which is more efficient. The
traditional mouse design consists of two buttons and a rotating disk.
The buttons allow you to select and open option menus, while the bar is used to scroll up and
down.
5- Bugles
Horns are peripheral output devices. These allow to amplify the sounds coming from the
computer. Some equipment has built-in horns, while others require the installation of external
horns.
6- Microphone
The microphone is a peripheral input device. This is responsible for capturing the sounds that are
produced around the computer.
Once the sound has been captured, it can be stored on the computer (as a recording), sent to
another computer (as a call) or sent to the horns to be amplified.
54
7- Camera
The camera is a peripheral input device that is responsible for capturing images and videos.
Along with the microphone, you can record videos with audio.
Information received by a camera can be stored (in the form of audiovisual recording) or
transmitted to another computer (via a video call).
8-Printer
Printers are information output elements. Thanks to these, the data stored by a computer can be
captured on paper.
The first printers were of impact and functioned with a technology similar to the one of the
typewriters: it was printed letter by letter. However, they were very slow and noisy, so they were
displaced.
Currently, the most used printers are thermal and laser printers. Thermal printers work thanks to
rollers that get wet with a mixture of ink and wax.
Subsequently, the roller passes through the paper and forms the information. Black and white
thermal printers use a single roller, while color printers have three (one for each primary color).
For their part, laser printers work with toner (a kind of powder), photoconductive rollers and
laser beams. These printers are the fastest and most efficient on the market.
9- Scanner
The scanner is an information entry system. This works like a photocopier, because it reads an
image and produces a copy of it. The difference is that the produced copy is digital and is stored
in the computer's memory.
This device consists of two essential elements: an optical system and an analog-digital converter.
The optical system is responsible for studying the image to be scanned, determining the colors
and tones present on the page.
The information provided by the optical system is analyzed by the analog-digital converter. This
transforms this data to the binary system, so that the computer can interpret and store the image.
Correct sitting position

The correct sitting position is the posture in which you hold your sit or use ergonomic furniture
to keep the bones and joints in the correct alignment. This helps in decreasing abnormal wearing
of joint surfaces as well as reduce stress, backache, eye strain and fatigue. Good sitting position
requires a table to be of the right height relative to the chair to provide comfortable hand
positioning as shown in Figure 3.2. The seat should have an upright backrest and should be high
enough to allow the eyes of the user to be level with the top of the screen

3. Ways of keeping a computer properly so that it does not get destroyed.
After using a computer, after the lesson, a learner is asked to wipe it off dust
or dirt, shut it down, handling it with care as she/ he carries it to the place
where it should be kept or any other place designed and prepared tokeep
computer safe.
4. Showing proper the way of sitting when using a computer and giving
explanation/reasons why, you must sit that way;
Every learner sits before his/her computer placed before him/her on the top
of the desk, and then shows the proper way eyes, back, feet, fingers, are
supposed to be when using a computer and give reasons why so.
Sitting well, when using a computer, keeps us free from eye problems,
backache, fatigue and others…

B. Answers for end unit assessment
(Questions are in the Pupil’s book)

1. Soil has 3 major types; clay soil, sand soil and loam soil.
You differentiate types of soil by making experiments to check their water retention capacity
in order to know how long the soil can retain /keep water.
2. Answers to this question;

a) In modelling decorations, we use clay mixed with little fine sand. True.
b) When we want to identify the type of soil, we are guided by its smell. False.
We use water and observe how faster water penetrates and how long it retains/ holds water.
c) When modelling pots, we use kneaded clay, then dry it and burn it so as to harden it. False.
3. Answer YES or NO in the questions below:

a) When modelling decorations, bricks, and pots we use loam soil. NO.
b) Sand soil is the best soil suitable for plant growth. No.
c) Soil Erosion is caused by running. Yes.
4. Not every soil can be used to construct houses because each type of soil has different capacity
to hold and retain water so as to form mud.
Example: Sand soil cannot hold water for a long time, and when it loses water it breaks into pieces.
5. Other things that destroy soil apart from water are; Wind, wastes which do not rot (polythene
bags, plastic bottles, metals, glasses,). Wind blow when it is too much, blowing of the top fertile
67
soil / humus leaving behind infertile soil that is like a desert. Wastes which do not rot destroy soil
because they cause poor soil aeration (the penetration of air into soil).
6. The importance of water in soil. Water makes soil soft which enables plants to grow well.

1. State at least one type of soil you know.
Answer: Sand Soil, Clay soil, loam soil.
2. Sand soil is the best soil suitable for cultivation of crops and plants. Answer/ No

1. Outline 3 types of soil.
Answer: Sand Soil, Clay soil, loam soil.
2. Describe the importance of water in soil.
Answer: Water makes soil soft which enables crops/ plants to grow, water also leads to growth of
grass and animals get food.
3. State any two examples of wastes which are not good on soil.
Answer: Plastics and bottles.

1. Explain the technique (method) used when we want to know the type of soil.
Answer: We use water and observe how faster water penetrates and how long it retains/ holds
water.
2. By giving an example, explain why not every soil can be used to construct houses.
Answer: Because not all soils have the capacity to hold and retain water so as to form mud.
Example: Sand soil cannot hold water for a long time, and when it loses water it breaks into pieces.

7.5. Additional content for the teacher

Importance of Heat, Uses and Applications of this energy in Life
Heat is a form of energy that exists naturally.
It quickly changes into different forms of energy like light, electricity, etc.
Life on this earth depends on heat energy for survival.
The man knew about heat and its precursor fire for ages and used it for various applications.
Heat energy, unlike other forms, can be felt by the sense of touch.
Importance of Heat
Heat and energy are quite related and are known to man before advancements in science. It has a
significant role in human lives and also the environment. Heat energy helps to
1. Photosynthesis
In plants, light energy from the sun converts to heat energy and gets trapped in the leaves to form
carbohydrates.
This heat energy is trapped as carbohydrates again releases the heat in the body. The heat energy
is formed by the breakdown of carbohydrates in the animal tissues. This heat is measured as
body temperature and is kept uniform throughout the body by blood distribution.
Besides carbohydrates, heat energy is also stored in the form of fats and, to some extent, in
proteins.
Thus the energy in the form of heat is involved in food production and temperature maintenance
of warm-blooded animals.
2. Enzyme reactions
Enzymes are bio-catalysts that help to enhance the speed of biochemical reactions. These
86
enzymes operate only at suitable temperatures, i.e., heat energy.
At low temperatures, they are inactive, and the reactions do not proceed. At high temperatures,
they get denatured (destroyed). Hence, they need optimal temperature for function. So without
heat, they are non-functional.
Therefore, you can notice that high body temperature, like in disorder like sunstroke body
becomes weak due to physiological dysfunction.
3. In Medicine
Heat plays a vital role in health care. The heat has the ability to counter inflammation and reduce
pain. Hence, heat is used in the treatment of inflammatory and pain-related problems.
Drinking hot water during a common cold or cough helps relieve the symptoms. In the case of
piles or hemorrhoids, a sitz bath is recommended to minimize local pain.
Similarly, having a hot water bath reduces body pains due to the anti-inflammatory effects of
heat energy.
Hence, as a part of nursing, thermotherapy is used in the form of heating pads, hot water, cloth,
etc. It is believed that heat increases blood circulation, promotes healing.
4. Water cycle
The water cycle is a phenomenon responsible for the rain and life on earth. When the heat from
the sun contacts water on the earth, it evaporates by forming water vapor.
This evaporation mostly happens from the oceans to form clouds. In turn, these vaporous clouds
reach the land through the sky, get cooled, and cause rains. The rainwater collects in pools,
ponds, rivers, etc., and the excess returns to seas and oceans.
This cycle is called a water cycle, and this happens due to the heat gain and heat loss (cooling)
mechanism. When the water gets heated, it evaporates from the earth, and when the clouds get
cooled, it causes rain on the planet. So heat from the sun is responsible for showers and life on
earth.
During heat temperature in summers, even water on land also evaporates. The water vapor, when
it rises above, convert into clouds and cause rains when cooled. But most of the water is from
oceans than from land.
5. Chemical reactions
Many chemical reactions like synthesis, breakdown occur in the presence of heat energy. Due to
heat energy, the electrons and atoms in the substances which are in the stable state are set into
vibration.
These vibrations make it easy to form new bonds and new molecules. Thus heat brings in a
change in molecules and substances. Hence you can even notice medicines containing the label
87
“store in a cool place.”
This is because exposing them to heat can lead to reactions and spoil the drug ingredient within.
6. Automobile motion
All the vehicles which run on petrol and coal operate due to the generation of heat energy within.
The heat energy helps the pistons to move, which is conveyed into cyclic motion, and thus, the
wheels rotate.
The more the heat generated, the more the speed and strength of the movement. Therefore, heat
energy is the base for all automotive vehicles like cars, buses, trucks, etc.
7. Cooking
Cooking is a daily routine at home, followed by the man to make his food. Cooking helps keep
the food tasty, easy to digest and kills any microorganisms which might be harmful to
health. Heat transference during cooking renders the food material and fiber more soft and pulpy.
8. Electricity generation from solar and earth
Electricity is generated by any means like by use of dam water, coal, nuclear energy, wind, and
even solar energy.
Of them, solar and coal methods employ the use of heat to generate electricity.
Especially coal is used in large quantities in many countries to generate heat and thereby electric
current.
Even a few advanced countries use geothermal energy (renewable) to generate electricity by
safer means (non-polluting and harmful to the environment).
This geothermal energy also is heat inside the earth.
9. Melting and moulding of metals
Metals are the hardest substances that are used widely for building, vehicles, hardware, etc.
These metals cannot be molded with the application of pressure. But hey can be molded easily if
heated.
Sometimes hard metals like iron are heated to red hot conditions to mold them into proper shape.
10. Drying
Drying is done by the removal of water from surfaces. This is possible by wind currents and even
vacuum. But the most common method is by use of heat. Sun’s heat helps in drying clothes, soil,
and any other wet surfaces.
88
Transferring heat to moist clothes sets the water molecules into motion; thereby, they quickly
move away into the air leaving the cloth dry.
11. Sterilization
This is a process to kill any microbes in drugs and other healthcare material. This aims to keep
the preparation sterile until use. So heat sterilization is the most common and highly effective
method of doing it.
Methods like autoclave, hot air-oven, incineration use heat energy in the process of sterilization.
But the process can be achieved when the material is exposed to a specific temperature and a
suitable duration of time.
12. Incubation to grow birds in the eggs
You might have heard that hens sit on their eggs to hatch them. After the hen lays its eggs, it sits
on them and provides heat for the egg’s embryo to grow.
It does so for 21 days, after which a fully formed chick comes out of the egg. In general, in birds,
the body is quite warm due to feathers, and when they sit on their eggs, they pass on the heat.
This heat energy helps in the growth of the embryo into a bird.

8.5. Additional content/information for teacher

How do we taste and smell through the nose?
The primary detectors of taste are the taste buds located on the tongue. The connection of the
nasal cavity to the back of the mouth/tongue allows for the detection of the all so important
flavor. Back to the point that smell = 80% taste, this is why it is hard to taste anything when your
nose is blocked.
