Mass+and+Oscillations

I am happy with the results, but ...

It is interesting that they had a lot of trouble counting the frames. The best apporach would be to make them do it over and over again until they had the proper results. In the efforts to have people not too far behind, we gave them too many hints.

The classification of variable into independent, dependent, and control variables was a little too rushed.

As in the previous activites, we ran out of time. The time issue has to be revisited.

Everybody had difficulty with the design part. Maybe the movies should be about a cart oscillating on an air track. This resembles more closely the design we seek.

We did not get to do the stats. We wanted to reinforce the stats procedure that were introduced in activity one. Our plans are to do it two weeks from now when we do the energy videopoint acitivity. We start with the stats of the oscillation lab and we shorten the energy activity.

We also have to reinforce the dependent, independent, and control variable concepts.
