3, 2, 1, go!

Experiment 1:

  • Put the Minifigures on your bobsled and test how far it'll go.
  • Use a yardstick to measure the distance your bobsled traveled.
  • On your worksheet or a similar chart in your notebook, record the distance traveled.
  • Do 3 test runs.
  • Record the distance your bobsled traveled each time, and then circle the middle distance.

Faster!

Experiment 2:

  • Now, test your bobsled with the black block that you've built. Mark your prediction for how far it'll travel.
  • Do 3 test runs.
  • Record the distance your bobsled traveled each time, and then circle the middle distance.

Faster... faster!

Experiment 3:

  • Now, compare the heavy black brick to the black block you've just tested.
  • Again, use a brick to mark your prediction.
  • Test 3 times to see if you were right.
  • Don’t forget to record the distance each time and circle the middle distance.

What did you see?

  • Which forces did you observe?
  • Did you see any patterns?
