Laboratory twelve in SC 130 Physical Science focused on electricity.

Merna, Agnes, Donnalyn, among others compare the currents and voltages.

Jessica watches Charleen light the bulb after experiencing a hot wire short circuit.

Roxie examines the ammeter.

MacArthur and Alden working on testing for electrical conductivity.

Board notes. The week had started with the third disk in the alternate energy series, installation of a micro hydro system. 455 might be a better choice as 454 spent a good half an hour on installation specifics. 451 might also be preferable. That said, 455 had how to calculate power production for a high head micro hydro system.

The concepts of flow and head translate well to current and voltage for electricity.
