1. 3rd Quarter: Week 2 Day 1
SCIENCE 6

2. Gravitation and Frictional
Forces

4. What enables objects to move?
What is friction? What are the
kinds and types of friction?
How friction does affect motion
of an object?

5. Let the learners look at the picture of a
waterfalls
What causes the water to fall towards the
earth?

6. What comes to your mind when you hear the
word gravity? Write it in the circles below.

activity 1
• b.Activity proper as the teacher

• c.Presentation/Reporting of Pupils
output

9. Activity 1
Observing force of Gravity
I. Problem: Does weight affect how fast an object falls? What causes the objects to fall towards the earth?
II. What you need:
Ball ( plastic and metal balls) notebook
Platform balance eraser
III. What you need to do:
1. Measure the mass of the different objects. Record it below
2. Get two different balls,One in each hand at the same height.
Stand and stretch your arms in front of you at the shoulder height
3. Drop the two balls at exactly the same time and listen for them to hit the floor. Record your result
4. Repeat steps 2 and 3 three times to be sure that your observations are accurate.
5. Do the activity using a pencil and an eraser.Record your observations.
Objects used
Object that hits the floor first
Mass Trial 1 Trial 2 Trial 3
Plastic ball
Metal ball
Pencil
eraser
What have you found out?
1. Which ball consistently hits the floor first? __________________________________________________________________________________
2. When you dropped different objects, which hit the floor first – the lighter or the heavier one?
Why?________________________________________________________________________________________________________________
3. What force acts on the objects as they fall on the floor?________________________________________________________________________
4. How is the mass of an object related to the gravitational force of attraction?________________________________________________________
Conclusion:
How is gravitational force related to the mass of an object?________________________________________________________________________

10. EXPLANATION
(CONSTRUCTIVISM APPROACH
• Which ball consistently hits the floor first?
• When you dropped different objects, which hit the
floor first – the lighter or the heavier one? Why?
• What force acts on the objects as they fall on the
floor?

11. Activity 2
Observing Gravity
1. Problem: What happens to the water? Why?
II. What you need:
Styrofoam cup,
a pencil,
water,
and a bucket
III. What you need to do:
1. Poke a hole in the side of the cup with the pencil. Make the hole about 2 inches above
the bottom of the cup.
2. Cover the hole with your thumb and fill the cup with water.
3. Hold the cup up high and uncover the hole. Make sure the water flows into the bucket or
do this experiment outside. What happened to the water? Did it gush out of the cup?
Cover the hole with your thumb again and fill the cup.
4. Now make a hypothesis: If you drop the cup into the bucket, would the water flow more
quickly or more slowly out of the hole in the cup?
5. Hold the cup high and drop it into the bucket. What happened to the water coming out of
the hole?
IV. What have you found out?
1. What happened to the water? Did it gush out of the cup?____________________________________
Cover the hole with your thumb again and fill the cup.
2. Now make a hypothesis: If you drop the cup into the bucket, would the water flow more
quickly or more slowly out of the hole in the cup?__________________________________________
3. Hold the cup high and drop it into the bucket. What happened to the water coming out of the
hole?_____________________________________________________________________________
__________________________________________________________________________________
V. Conclusion:
Why did the water gush out of the cup?__________________________________________________

12. Video viewing:

13. At home you have a mango tree
with lots of fruits. What will happen to
the mangoes fruits if you will just leave
it there without harvesting? Why do
you think this happened?

14. Gravity - is a force that tries to pull
two objects toward each other.
Earth’s gravity - is what keeps you on
the ground, what causes objects to fall,
and is why the objects fall down rather
than up!

15. Direction: Read and analyze the statement silently
then choose the letter of the correct answer.
1. What is gravity?
A. It is the force that creates tidal waves
B. It is the relationship between the Earth and the moon
C. It is one of the four physical forces found in nature
D. It is the force that holds the Earth together
2. What must you do to overcome gravity?
A. push or pull
B . fall
C. add weight
D. check distance

16. 3. Which object would be most difficult to lift against gravity?
A. a marble
B. a soccer ball
C. a chair
D. a car
4. How does Earth’s gravity affect objects near Earth?
A. It pushes them away.
B. It pulls them in.
C. It makes them larger.
D. It makes them move faster.
5. Which is the best example of gravity?
A. A car hits a tree, and its motion stops
B. A breeze blows, and a sailboat moves
C. A book is pushed, and it moves across the table
D. A person drops a ball, and it falls to the ground

17. Assignment
Make a research about
situations which show the
presence of gravity.
