Students propose 3 Tallest as fastest ramps

7 of 13

Students propose 3 Tallest as fastest ramps

8 of 13

Students propose 3 Tallest as fastest ramps

Students accept height as the major variable but don’t agree on fastest ramp.

We’ll collect data on one of the ramps:

  1. Get in groups of 2.
  2. Assign Roles:
    1. Stopwatch Operator
    2. Data Submitter�
  3. Submit Data-energizingphysics.com → Workshops → #8

Review Data

  1. Why doesn’t every group get the same speed for each trial?
  2. How does this graph help students understand data variation?

What other data could you collect?

  1. Individually, consider the following
    1. Could you dig deeper into this ramp data?
    2. What other data you might be able to investigate with Google Forms?
  2. Turn to your neighbors and share ideas.
  3. Share out to the whole group.
