Unit Rationale
Children have a natural curiosity about the world around them. Science helps student
interpret the world and human how humans live. With the day and age we live in, it is essential
that students are aware of how our waste affects our planet. Waste goes beyond human
consumption; therefore, students will also learn about the wastes produced through nature
and its natural recycling processes. Many things are recycled through the environment
repeatedly, such as plants, animals and other living things – this helps make up the world
around us. This is an important unit for grade fours to study because students will be able to
identify wastes produced within their community. In addition, students will learn various ways
to recycle and dispose of the wastes humans create. These methods go beyond recycling paper
and cans, as we will discuss how some materials are biodegradable, some are reusable and
some are toxic. In addition, students will learn the proper ways to dispose various items, how to
put safe methods into practice at home and learn how these wastes affect our community.
Students will realize and learn that their personal action in reducing, reusing and recycling at
home or at school can decrease the waste we accumulate and help positively impact the
community. This unit will take approximately a month and a half, and as mentioned above
students will explore a variety of topics in relation to waste and our world.

11. Identify actions that individuals and groups can take to minimize the production of
wastes, to recycle or reuse wastes and to ensure the safe handling and disposal of
wastes.
12. Develop and implement a plan to reduce waste, and monitor what happens over a
period of time.
Lesson Overview:
*1 Lesson = 30 minutes
Lesson 1: Introduction to Waste & Our World.
Each student will be given 3 sticky notes. On each sticky note they will write down one
thing they throw out.
On the front white board will be 3 columns titled – Compost, Recycling, Garbage. As a
class, we will sort through the items listed on the sticky notes and discuss which
section they would fit best in.
Once student’s ideas are flowing, they can work on their unit title page for their
binders. (this will act as a sponge activity the first couple of classes if necessary)
Lesson 2: The Dirt on Decomposers: How Exactly Does Nature Recycle Organic Waste?
YouTube: Crash Course Kids Video on how decomposers help the earth recycle organic
material.

Interactive Smartboard presentation – types of decomposers and types of plant matter
they break down. Ex// mold, fungi, insects, worms, microorganisms.
Outline the decomposing process – students will complete a diagram of the process.
“Types of Waste” Worksheet. – have student try to come up with examples not
discussed in class to further understanding.
Lesson 3: The Dirt on Decomposers
Continuation of lesson 8.
Depending on students understanding this may take another lesson to make it
concrete. *
Lesson 4: Organic Waste vs. Inorganic Waste: Is it Biodegradable?
Show YouTube video: “What Materials Biodegrade?” aka decompose.
https://www.youtube.com/watch?v=K4tEbAm3cCA&index=6&list=PLgVnXuJnaKvZjKEs

Pause video at approximately 1:30 and have students predict which items will break
down – Ex// Styrofoam, plastic shopping bag, cardboard, a piece of cotton fabric,
lettuce, aluminum foil, an apple, a glass jar, and a piece of paper. Items will be sorted
into “Organic and Inorganic’ categories.

Students will write down - How could these 5 items be ‘reused’? What could you
make with these items? They will draw pictures to accompany their answers.
Share time. Students can share their ideas with their classmates. (Hand in this
activity).
Lesson 18: What Items Can We Reuse?
Continue activity from lesson 17
Lesson 19: Recycling Electronic Waste.
Read news article “Waste and Our World – What do we do with electronic waste”
Students will answer a couple questions about the reading – reading comp.

Discussion – who has recycled e-waste? Where can we take these items in Medicine
Hat?
Lesson 20: Too Much Packaging
I will bring in various household items that have too much packaging.
Students will get into groups and examine each item. On their chart worksheet,
students will write down how the packaging can be recycled or how the amount of
packaging for the item could be reduced.
Lesson 21: Too Much Packaging
Continuation from lesson 19
“No Garbage Lunch Day” – Students will be challenged to bring a lunch that has no
garbage. We will discuss what students have in their lunches and the garbage or
recycling items they have.
Lesson 22: Too Much Packaging
As a class discuss the advantages and disadvantages of packaging.
Taking what we have learned about the different types of packaging, students will
complete a worksheet to discuss the pros and cons of various kinds of packaging.
Edmonton Public Schools Pg. 63-66.
Lesson 23: Looking at Home Data
Have students make a chart and record the number of ways they could minimize the
amount of waste in their lives over the course of a day or week. Chart the individual
reductions of waste and represent all students’ responses in a class bar graph. Using
the class total, we will make calculations. What would add up to in a month? A year?
(I decided to push this activity back in the unit to make sure students have sufficient
time to record their data at home and bring it in)
Lesson 24: Looking at Home Data
Continued calculations from lesson 23
As a class we will discuss, analyze and calculate data based on their records of waste
from home.

Assessments Strategies
Formative Assessments: Students will be
assessed formatively many times during this
unit to check for understanding. I will use
multiple strategies to formatively assess what
students have learned (assessment for
learning). These assessments will be weighted
5% and participation based. For example:
Group discussions will be used often. This is a great way for students to get out their
ideas and rally ideas off each other. Through this formative assessment technique, I will
be able to see what students already know or have learned from the lesson. In addition,
students will be able to see new perspectives from their peers.
Exit Slips will be used to check for understanding after various lessons. This is a suitable
way to see what students learned after a lesson, and will allow me to see if students
understand the concept, or if we need to take another class to better develop their
understanding.

Daily observations are also important in formatively assessing students. I will be walking
around the room when students are working on assignments to ensure that they
understand. For instance, if many students are stuck on the same question, that will tell
me that we may need to go over that specific concept again.
Various other activities will be formatively assessed also. I want to make sure students
understand the significance of waste in our community. For example, students will have
a small take home assignment to tally the amount of garbage they throw away over the
course of a week at home, I will be looking to see if students participated, not that data
they bring back to school. Also, after the case study on our oceans and marine life,
students will be tasked with creating a poster to remind people to recycle - these
posters will be hung up around the school. This formative assessment is more about
reminding others in our school to reduce, reuse, recycle, etc., rather than the artistry of
their poster.
Summative Assessments:
Worksheets & Assignments: several worksheets and assignments will be taken in for
marks. I will mark these personally, or we will mark them in class. I want to give
students feedback. These various assignments and worksheets will be the bulk of their
“Waste and Our World” unit mark and weighted 40%.
Unit Test: At the end of our unit, students will be tested on what they have learned. This
test will be weighted 30% of their “Waste and Our World” unit mark. This test will show
me what students have learned over the unit. I have scheduled two classes to write this
test to ensure that all types of learners have sufficient time.
Unit Project: Towards the end of the unit students will create a unit project to display
their learning and link all the major topics and themes in this unit together. The concept
of this project is to teach someone who knows nothing about waste in our world, about
how to identify wastes, recycle wastes, reuse wastes, reduce wastes, etc. Students will
have a choice in how they want to present their information, they can either create a
pamphlet, use google slides or make a large poster. I want to accommodate all learner

types– visual, tactile, etc. – therefore, I think giving students choice will be an engaging
way for students to display their understanding. The unit project medium will be
marked the same based on a rubric. For example, it does not matter if a student decides
to make a poster, a pamphlet or a presentation, they will all be marked on the same
criteria. Before students start their assignment, we will go over the rubric and criterion
to ensure that all students understand their task. I have scheduled four classes for this
project, however, I am open to spending more time on this if students are working hard.
Since we will be spending a good chunk of our unit on this project and it links everything
students have learned together, this project will be weighted 25% of their “Waste and
Our World” unit mark.
