Late Christmas present
Just before Christmas I made a blog post about a small solar car that I bought as a stocking filler for my son. I tried it out and decided to buy a whole bunch of them for my class. I also bought some lamps, plug in dimmers and power meters. Today I tried it out with my SL class and they had no trouble thinking of several interesting research questions. None of them have finished the analysis yet (it was only 2 hours ago) but it looked like they were getting some consistent results. With out giving the game away there are a lot of variations in both independent and dependent variable. In the photo you can see the power meter piggy backed on the dimmer, worked quite well.
