Station 2-Reducing Friction

  1. Stack 2 or 3 heavy books on a table. Use one finger to push the books across the table.
  2. Place five round pencils under the books, and push the books again.
  3. Compare the force used in Step 1 with the force used in Step 2. Explain.
  4. Open a jar with your hands, and close it again.
  5. Spread a small amount of liquid soap on your hands.
  6. Try to open the jar again. Was the jar easier or harder to open with the soap? Explain your observations.
  7. In which situation was friction helpful? In which situation was friction harmful?

Station 1-First-Law Magic

  1. On a table or desk, place a large empty plastic cup on top of a paper towel.
  2. Without touching the cup or tipping it over remove the paper towel from under the cup. How did you accomplish this? Repeat this step.
  3. Fill the cup half full with water, and place the cup on the paper towel.
  4. Once again, remove the paper towel from under the cup. Was it easier or harder to do this time?
  5. Explain your observations in terms of mass, inertia, and Newton’s first law of motion.

Station 3 (The Friction 500)

  1. Put a toy car at the top of the ramp, and let go of the car.
  2. Put the car at the top of the ramp again, and let go of the car. Record the time it takes the car to travel down the ramp.
  3. Change the surface of the ramp by covering it with sandpaper. Record the time.
  4. Change the surface of the ramp by covering it with a cloth. Record the time.
  5. Which surface had the most friction? Why? What do you predict would happen if the car were heavier?
