Most of today was taken up with the density column project--I explained it, handed out test tubes, and everyone went to their lockers to deposit them. So far, only one is broken. I am charging a dollar if it is broken, which seems like a lot to me, but I feel it is necessary to impel students to make sure they take care of them and bring them back. My return rate in the past was about 80% (when it only cost 50 cents). Of course, back then a gallon of gas was $1.20.
We also went outside with spectroscopes and got to see how color can be measured, using numbers (the wavelengths of light in nanometers) to show which specific colors are given off by a source. The sun gives off them all (we did not look directly into the sun), while the room lights give off five bands.
I also stuck the DVD case on the cabinet using only water. Last year it stayed up the whole year. I can only hope!
Sweet justice.
