    This lesson plan aims to teach students the difference between physical and chemical changes. It includes objectives, learning resources, and a step-by-step method. The method involves introductory activities like prayer and a review game. Students then participate in demonstrations of physical changes like cutting paper and chemical changes like rotten fruit. They are divided into groups to perform experiments with water and marshmallows over candles. Finally, the lesson is generalized and students are assigned an observation activity for the next class.

    IV. Methods and Procedures

    A. Preliminary Activities

    a) Prayer

    Before anything else, let's start our day with a prayer. I want everyone to stand up
    and bow their heads.

    Dear Jesus, please show me how to spend this day sharing your love in every way.
    Help me to be kind to everyone, to play and laugh, and to have lots of fun. Shining
    your light, giving your grace, and sharing your joy with a smile on my face. Angel of
    God, my guardian dear, to whom his love commits me here, be at my side to light
    and guard, to rule and guide, Amen.

    b) Greetings
    Good afternoon, Grade 5! Are you ready to listen? I'm teacher Mawi, and this is
    teacher Betty.

    c) Checking of Attendance

    Before that, let’s first check the attendance, May I know if there’s a student who
    didn’t attend our class today?

    d) Classroom Management

    Okay, now I want everyone to pick up the trash that you will see and put it on
    your bag for meantime and please arrange the chairs. Students at the back,
    please occupy the vacant seat.

    We have the rules to follow to have a peaceful discussion.


    1. Listen to the speaker and avoid talking to your classmates especially when
    someone is talking.
    2. Raise your hand quietly if you want to answer questions.
    3. No cellphones during class.

    B. Motivation Activities

    a. Review

    Class, last time, we talked about matter, right? So, who can tell me what matter
    is? What are the three states of matter?

    b. Motivation

    Before we go on with our lesson for today, we will play a game first. Do you want
    to play a game? This is known as 4 pictures, 1 word. So, I'm going to show you
    four different pictures, and you're going to guess what word those pictures refer
    to. Are you ready, kids?
    C. Presentation of lesson

    Okay, very good class! Now I have a paper here. What do you think we can do to
    change this paper?

    (The teacher will do what the students suggested)

    Now that I changed the paper in a variety of ways, do I still have the paper?

    What are the changes that happened in the paper in terms of size, color, shape?
    With the first set of changes to the paper, we still have the paper right? We can still
    put it back together.

    Okay class, that activity has something to do with our lesson for today.

    Do you have any idea about the topic for today?

    It’s about Physical and Chemical Changes

    - What Is a Physical Change?

    In a physical change, the material involved in the change is structurally the same
    before and after the change. Physical changes can further be classified as
    reversible or irreversible. Types of some physical changes are texture, shape,
    temperature, and a change in the state of matter. A change in the texture of a
    substance is a change in the way it feels.

    Example:

    Freezing
    -Changing of liquid to solid.
    Melting
    -Changing of solid to liquid.
    Evaporation
    -Changing of liquid to gas.
    Condensation
    -Changing of gas to liquid.
    Sublimation
    -Changing from solid to gas without passing the liquid state

    Like what we did earlier, cutting papers into smaller pieces is an example of physical
    change because it is still a paper; the only change is the size of the paper.
    Another example: I have here a banana; if I cut it into two, it's still a banana. It only
    changes the size and shape.

    Other examples of physical change:

    - Melting Ice Cube


    - Broken Pencil
    - Paper Boat

    So again, Physical change is a change in the substance’s appearance without


    changing its composition.

    Now, who can give me another example of physical change?

    - What is Chemical Change?

    A chemical change occurs when the composition of a substance is changed, which


    requires the breaking and forming a new substance. This results in the rearranging
    of atoms in substances to form the products of a chemical reaction, which are brand
    new molecules that cannot be easily reverted to their original state or irreversible.

    Chemical changes are also known as chemical reactions. The “ingredients” of a


    reaction are called the reactants, and the end results are called the products. The
    change from reactants to products is signified by an arrow:

    Reactants → Products.

    Another example is this rotten banana, which undergoes a chemical change. A


    rotten banana is considered a chemical change because it involves a chemical
    reaction between enzymes and oxygen in the air. So, when exposed to the air, these
    chemicals react in a process known as oxidation, which causes the food to turn
    brown. Constituents will break down within the banana to form substances we
    cannot see that contribute to these changes.

    Rotting, burning, cooking, and rusting are all further types of chemical changes
    because they produce substances that are entirely new chemical compounds.

    Other Examples:
    - Burning of wood
    - Cooking and egg
    - Burning of paper
    -
    Chemical change is a change that forms a new substance with new properties.

    Can you give other examples of chemical change?


    D. Application

    Now that you understand the difference between physical and chemical change,
    we’re now going to have a group activity. You will be divided into two groups.

    We will have a simple and minor experiment to show the physical and chemical
    changes. Each group will be given tools and guide procedures to do the experiment.

    GUIDE PROCEDURES

    Group 1

    WHAT TO DO:
    1. Put the water on the spoon.
    2. Place the spoon on the lighted candle.
    4. Hold the spoon with a hand towel.
    3. Continue until the water boils.

    Materials What did you Does it produce Physical or


    do? something? Chemical
    Change? Why?

    Group 2

    WHAT TO DO:

    1. Put the marshmallow on the stick.


    2. Place the marshmallow on the lighted stick.
    3. Hold the stick with a hand towel.
    4. Continue until the marshmallows are burned.

    Materials What did you Does it produce Physical or


    do? something? Chemical
    Change? Why?
    E. Generalization

    Good Job, everyone! Now that you answered your group activity, I believe that you learn
    something about physical and chemical changes.

    Who can tell me what is the difference between physical and chemical changes?

    - Physical change is a change in the substance's appearance without changing its


    composition.
    - Chemical change is a change that forms a new substance with new properties.

    F. Valuing

    Why do you think that knowing how physical and chemical changes occur is
    important to us?

    It is important for us to understand the changes in matter, as these changes are


    happening in our daily lives. Chemical and physical changes occur all around us all
    the time. These changes are essential parts of our daily lives, for example,
    digesting food, combustion, and phase changes. However, a few of the chemical
    and physical changes that occur daily are harmful for the environment.

    G. Evaluation

    V. Assignment: OBSERVATION

    VI. 1. light the candle with


    matchsticks
    VII. 2. observed and write your
    observation in the
    VIII. chart
    IX. 3. pass it tomorrow
    WHAT TO DO:
    1. Light the candle with matchsticks.
    2. Observed and write your observation in one piece of paper.
    3. Pass it tomorrow.
    Make sure that you have someone who will guide you before doing the activity.
