2. What is friction? Friction is the rubbing of two surfaces. It is the force of two surfaces coming in contact with each other.

3. You can make friction very easily:

4. Rub your hands together. Picture source: http://www.imsa.edu/programs/kidsinstitute/wheels/fi4.phphttp://www.imsa.edu/programs/kidsinstitute/wheels/fi4.php

5. Do you feel heat ? That is the result of friction.

6. Check out this website on friction: http://www.fearofphysics.com/Fricti on/frintro.html

7. We CAN, however, use some things to minimize friction: Oil (lubricant) Ball bearings Water Polished metal (slide)

8. Watch Bill Nye the Science Guy: Motion and Friction for more information.

9. What would it be like to have no friction? Watch the “Magic Schoolbus Plays Ball” video to find out.
