Science 6_3rdQuarter_Week1

1. Day 1

2. Directions: Rearrange the jumbled letters to form the concept
learned in the previous lesson through context clue. Write
your answer in your Activity Notebook.
1. CREOF – is a push or pull that starts, stops, or changes the
direction of an object
2. GAMENT – keeps refrigerator door stays closed to conserve
energy
3. AGRIVYT – keeps orbiting planets in place as they moved
around the sun
4. TRICITYCEEL– allows computer and other gadgets at work
5. CLEARUN – is the force that holds the particles in the
nucleus together

3. What would life be
without friction?

4. Friction is a force that opposes motion between two
surfaces sticking or touching together. It causes an
object that moves along a surface to slow down and
eventually stop. Friction or Frictional force is always
high or more on a rough surface and it is low or less on
a smooth surface. The movement of people and
objects are greatly affected by friction in relation to the
kind of surface where they travel or move.

5. Friction can be classified as sliding, rolling, fluid, and static.
Friction is useful, but sometimes harmful. It brings desirable
and undesirable effects to objects and people. Friction could be
reduced by applying lubricants to surfaces, reducing and
minimizing contact between surfaces, and using aero dynamic
shapes. Therefore, it would be best to observe and practice
precautionary measures all the time while performing our daily
tasks and activities at home and in school for
our SAFETY.

6. Directions: Connect the phrases in Column A to its appropriate
pictures in Column B.
Write the letters of the correct answer on your Activity
notebook.

7. Directions: Fill in the blank with the correct word to
complete the concept learned. Choose the correct
word from the box below. Use your activity notebook
in writing your answer.
I have learned that is a that motion between
surfaces or together. Frictional force is less or
on a surface while it is more or _____on a
surface.

8. Fill in the blanks with the correct answer. Choose
your answer from the box below.
When an object over a solid surface, rolling friction is
produced.
Some examples of objects that produced rolling friction
when rolled over a surface are rolling ball and of vehicles.
Rolling friction uses lesser force making objects to move.

9. Directions: Analyze carefully each given kind of surface and
condition. Write a 😊 symbol on the space if it shows a smooth
surface and a 😔 if it is a rough surface. Write your answer in your
Activity Notebook.

10. Day 2

11. What is Friction?

12. Have you seen or tried to ride a bicycle?
What do you think will happen if the bicycle has
no tires?
Will it move easily and take us anywhere we want
to play?

13. Directions: Read the directions carefully. Then, answer
the questions that follow. Write your answer in your
Activity Notebook.
Prepare the following materials:
3 old notebooks or books
5-10 ballpens or pencils

14. 1. Pile the 5 old notebooks or books.
2. Push the notebooks or books to move forward.
3. Put the ballpens or pencils on the table or floor.
4. Using the same pile of old notebooks/books put
it above the ballpens/pencils just like what is
shown in the photo.

15. 5. Push the notebooks/books to move forward.

16. Question:
1. Which set-up is easier to move, the pile of
notebooks/books without ball pens/ pencils
or the pile of notebooks/books with ball
pens/ pencils?
2. How do the ballpens/ pencils help in
making the pile of notebooks/books move
easier?

17. When an object rolls over a solid surface, rolling friction is produced. Rolling
Friction is the friction that acts on objects when they are rolling over a surface. In
activity 2.1, the pile of notebooks/books with ball pens/pencils under it moves
easily rather than without the ball pens/pencils.
Why? It is because of the cylindrical/spherical shape of the ballpen/pencil that at
some point had contact on the surface of the table or floor, making it easier to
move.
Rolling of ball or wheel on the ground are some examples of rolling friction.
Another common example of rolling friction is the movement of wheel on a
motorcycle. The weight of the driver and the motorcycle presses the tires of the
wheel against the ground. This downward force creates increased friction
between the tires and the road giving tire friction. If it were not for the
friction, the tires could not push on the road surface to drive the motor forward.

18. Directions: Put a √ if the object produces rolling friction if rolled
along a surface and X if not.
Write your answer on your Activity Notebook.
_____1. wheels of bicycle
_____2. rolling pin
_____3. 5 peso coin
_____4. marbles
_____5. wheelbarrow
_____6. table
_____7. cabinet with wheels
_____8. kite
_____9. soccer ball
_____10. rocks

rolled over a surface rolling friction is
produced?

4. Friction is a force that acts in the direction of the intended motion
of an object.
5. affects the motion of falling objects by acting the force of gravity.

39. Have you tried moving the
cabinet across the floor?

40. When you push an object like a book on the floor or table, sliding friction
occurs.
Sliding friction occurs between two surfaces that come in contact with each
other. Sliding friction acts in a direction opposite the direction of motion.
In the case of a book, the book moves forward while sliding friction is in the
opposite direction. Sliding friction slows down the movement of the book or
object that is moving. This sliding friction prevents the object to move
forward as fast as it would. When sliding friction is acting on an object,
other forces must be present to keep the object moving. It could be a push
or force of gravity when the object moves in slope. Sliding Friction occurs
when two objects rub against each other or slide against each other. It is
caused by molecular adhesion between surfaces.

41. Observe the picture below.
 Have you imagined how
friction occurs in this setting?

players wear shoes with

over the surface.

47. Day 5

48. What is a Sliding Friction?

49. When you push an object like a book on the floor or table, sliding friction
occurs.
Sliding friction occurs between two surfaces that come in contact with each
other. Sliding friction acts in a direction opposite the direction of motion.
In the case of a book, the book moves forward while sliding friction is in the
opposite direction.
Sliding friction slows down the movement of the book or object that is
moving. This sliding friction prevents the object to move forward as fast as it
would. When sliding friction is acting on an object, other forces must be
present to keep the object moving. It could be a push or force of gravity
when the object moves in slope. Sliding Friction occurs when two objects rub
against each other or slide against each other. It is caused by molecular
adhesion between surfaces.
