A Wednesday and Friday holiday reduced electricity to an introduction to Ohm's Law and the power relationship. Monday's introduction had to be done without the microhydroelectric example from the MicSem video Power Comes in Many Forms. Power was $0.1885 per kilowatt hour at the last buy prior to class. By the next day power was up at $0.22 per kWh.  As I did in the spring I ran with a shared folder of photos from Drive. I think having at least one prop would help ground this in the physical world. The photos do not make clear that labels are usually on the bottom. This particular appliance recently stopped working. Wednesday the local cold hit. Thursday was going to be a low energy lab. Focused on Ohm's law. Batteries and bulbs was dropped. Conduction was dropped. The focus was on the new Ohm's law gear. The procedure was modified to use only a single digital multimeter. This meant changing the wiring t...

Monday opened with Bill Nye's Optics and light DVD, a technological throwback.  Wednesday I arrived early to set up the refraction demonstrations. I tried a new layout. Although perhaps this afforded better overall visibility, I am not sure this made anything any clearer. I am not sure the students could clearly see what I was demonstrating. The laser beam is very invisible inflight. Perhaps a little dye in the water would help.  Maybe a fiber optic lamp would help with the wrap up. Thursday opened with the two basins, one with water one without, to demonstrate refractive effects. This term I forgot the larger coins. Reflection off the surface of the water remains problematic for this demonstration. Probably better done at night with lighting from the sides below the surface of the water. Renae and Mia determine the index of reflection for a plane mirror This term in both the 8:00 and 11:00 class data collection appea...
