Day 150: Videos for Investigation, Not Consumption

Eugenia Etkina and her physics education research group at Rutgers
University have put together a great resource: a collection of videos
for student investigation, rather than consumption.

You can view the collection here, sorted by topic:

The two slinky videos above were taken from the collection, along with
the following questions:

1. What were the differences in the experiments in the first video?
What was the purpose of the second video?

2. Compare the speed of pulses of different amplitudes on the first Slinky.

3. Compare the speeds odf the pulses of the same amplitude on two
different Slinkies.

4. What do you think determines how fast a pulse will propagate on a Slinky?

5. What experiment you could preform to test your answer?
