Today we started chapter three--all about light.
It was a busy day, we first took care of some general classroom business by looking over our graded chapter two tests and also self graded our chapter two homework portfolios.
We then viewed some slides of rainbows, sundogs and halos--then looked at light being broken up by a prism. Some classes looked at copper giving off green light during intense heating--other classes were not so fortunate as unfortunately the gas valve in room 121 became stuck in the off position.
We finished off the day by looking through spectroscopes at both fluorescent and incandescent lights, then had a brief discussion about the speed of light and the light year. We looked at the galaxy Andromeda and discussed what was happening on earth when the light that we see today first left the galaxy 2 1/2 million years ago.
We also received a hardcopy of the chapter three take twenty homework assignments. Not bad for 80 minutes!
