Candle Question

We watched the following video 

Act 1 video

And then we noticed and wondered some things.

We looked at the next part of the video

Act 2 video

And then we estimated and calculated how long it would take for the candle to burn down.

The next step is to look at the video and see how long it really took.

Act 3 video

We noticed that some of our estimations were pretty good.  We also noticed how a graph would be a good tool to use.
