ENGAGE
I will ask the students a certain situation
related to the topic.
Will watering the plant everyday affects the
growth of the plant?
EXPLORE
Students will be grouped into 3. Each group
will have different activities related to the
topic.
LEARNING ABOUT VARIABLES
Group 1 Rainy Group
1. Cut three different sizes of paper with
the same ratio of length and width.
2. Make three planes with the same
design.
3. Use the same force to throw the
airplanes. Measure how far each fly.
Guide Questions:
1. How far did each plane travels?
2. Will the amount of force applied in
throwing the planes affect the distance
the plane travels?
3. Will the distance of the planes be the
same if they are in the same size?
Group 2 Stormy Group
The group will watch a video about the
variables as part of scientific inquiries.
Guide Questions:
1. What is variable?
2. What are the three types of variables
discussed in the video?
3. Describe each variables mentioned in
the video and give an example.
Possible Answers
1. Yes. Plants need water in making their
own food so it will really affect its
growth if it will not receive any water.
Students silently do their tasks given per
group. They will answer the following guide
questions after doing their activity.
Group 3 Sunny Group
Materials:
2 packs of coffee (different brands)
Plastic cups
Hot water
Timer (cellphone timer)
Guide Questions:
1. How long does it take for each coffee to
dissolve?
2. Which among the materials used is
changed? Measured and left
untouched?
3. If you stir the solution, will the coffee
dissolve faster?
EXPLAIN
I will clear out misconceptions about the topic
and will continue to discuss with the focus
questions.
1. What is variable?
2. What are the types of variable?
3. What type of variable is changed?
Measured? Or stayed the same?
ELABORATE
1. What have you learned from our
discussion about variables?
2. Can you describe each type of
variables?
3. In what other learning area can we
apply or relate our lesson? How?
EVALUATE
Multiple Choice: DIRECTIONS: Choose the
letter that corresponds the correct answer.
Write your answer on your paper.
1. What are the types of variables in a
scientific experiment?
a. Constant, independent and dependent
b. Control, dependent, independent and
codependent
c. Manipulated, constant and dependent
d. Manipulated, control and independent
Answers of the students related to the
activity may vary with respect to the
result they came up with.
Variables are the factors, traits, and
conditions you can modify and measure.
The types of variables are independent
variable, dependent variable and controlled
variable.
Independent variable is changed, dependent
variable is the one that is measured, and
controlled variable is the one unchanged or
stays the same.
Possible Answers:
1. I have learned about variables and its
types.
2. Independent variable is changed,
dependent variable is the one that is
measured, and controlled variable is the
one unchanged or stays the same.
3. Math, research, etc.
Students will answer on a ¼ sheet of paper.
After they answer, they will exchange papers
with their seatmates and check afterwards.
Possible Answers:
1. b
2. a
3. b
4. b
5. b
6. b
7. a
8. c

1. Amount of cream
2. Color of the coffee
Which one is the independent variable?
a. Amount of milk

3. I will feel lazy if I eat too much. The 2
variables:
1. Amount of food eaten
2. Level of laziness
Which one is the dependent variable?
a. Amount of food eaten
b. Level of laziness
c. Both a and b

Individual Scientific Investigation
Students works their assignment at home.
You are going to investigate how the size of the
solid being dissolved affects how fast it
dissolves in water. Using the Scientific Method
as a guide, you should design a simple
experiment and record your results. Be sure to
complete each step of the scientific method in
order. You should submit a written or typed
report to be graded.
Remember that you should have stated in your
conclusions whether the
hypothesis was accepted or rejected, and have
provided suggestions for further
experimentation. The written report will be
rated using the scoring rubric.
Procedure:
1. Obtain the two materials and examine them
closely: granules of table salt (uncrushed) and
crushed table salt.
2. Write a hypothesis in a testable form.
Describe a test you could conduct to
find out which of the two materials dissolves
faster.
3. Identify the variable that you need to control
in order to have a fair test.
4.
Identify
the
independent
(manipulated/cause)
and
dependent
(responding/effect)
5. List all the materials you need, including the
amount. You may ask these from your teacher.
6. Be sure to record all your observations and
tabulate them. Write everything that you
observed during the dissolving test.
