Lesson Plan

Scientific Theory taught: Friction

Procedure:

1. Ask children what they know about friction.

2. Use real life examples where friction plays an important role in order to allow children to build a relationship to what the principal behind friction is.

3. Discuss force and the physical effects of different levels of friction. Explain how friction is a type of force.

4. Allow children to handle the “slow rollers” materials.

5. Explain the function of the “slow roller” device.

6. Allow children to guess which “pads” have the highest levels of friction.

7. Question children on what they think the effects of the different “pads” will be.

8. Have children guess where the “slow roller can” will stop due to the insertion of different “pads”. Have them rank the pads from highest to lowest.

9. Observe the effects of each pair of pads.

10. Test their understanding of friction by asking them questions such as…
What would the world be like if there was no friction?
Would you be able to walk down the sidewalk if there was no friction?
What is the relationship between friction and ice skating?
