Science Worksheets for Grade 6: Moving on Different Surfaces

MOVING ON DIFFERENT SURFACES
Problem: How does friction affect the motion of objects?

Materials:

• spring balance
• block of wood with a string
• wooden board for your ramp
• wax paper
• masking tape

Procedure:
1. Set the ramp with one side higher.
2. Cover one side of the ramp with wax paper. This is your smooth surface.
3. Cover the other side of the ramp with sand paper. This is your rough surface.
4. Set the block of wood at the lower end of the ramp in the smooth surface.
4. Hook the spring balance to the block of wood.
5. Pull the spring balance slowly. Take note of the reading on the string balance ust before the
    block moves. Record your reading.
6. Repeat numbers 4-6 on the rough surface. Compare the data gathered.

Let’s write down our observation
What is the reading on the spring balance on the smooth surface? On the rough surface?

Guide Question:
1. Which surface registered a greater force in pulling the block? Why?
2. In which surface does the block of wood move easily or fast?

Conclusion:
How does friction affect the motion of an object?
