Investigating Friction

Follow the presentation below and watch the video to learn about friction. 

There is an investigation to try with an investigation sheet to fill out as well.

 You will need the following:

• Investigation Activity sheet (see attached)
• Toy car or something small which rolls (i.e. a tennis or ping pong ball)
• A big book (to use as a ramp)
• A ruler or measuring tape
• 4 difference surfaces for the object to roll onto. I have suggested: grass, wood, carpet and concrete but as long as the surfaces are of different textures you can choose differently.
