Forces and Energy – Making kinetic rollers and post-note friction lifting

Post It Note Tug of War

We will be doing a Post It Note friction experiment, take guesses on if a phone book can lift a person, or maybe even something bigger like a car, and see how strong we are.

For this project you will need:

  • – Post It Notes*
  • Scotch tape
  • C Clamps (optional – if you have some on order, you can revisit this experiment when they arrive for startling results)
  • Weights and a bucket (if using C clamps)
  • Your superhero strength (if not using C clamps)

Super Energy Rollers

We will also be building an energy roller that converts potential energy to kinetic energy. Once you have your roller…rolling…you can set up time trials or races!

For this project you will need:

  • Two solo cups with a hole in the bottom*
  • Two CDs*
  • Two Popsicle sticks*
  • 1 plastic or wooden bead like a pony bead*
  • 2 rubber bands (thick and sturdy)*
  • Hot glue*
