Today in class we played with some simple electrical circuits - working with 1.5V batteries and Christmas tree lights. Most students were able to see the effect of changing voltage on bulb brightness as well as changing the arrangement/number of light bulbs on brightness.
The relationship we were exploring is known as Ohm's Law - how voltage, resistance, and current all relate in a circuit. Notes on Ohm's Law from today can be found here.
Tonight's homework:
P. 405#1-7 (compare only on #4) - you should have already completed the reading on this material, plus today's activity/notes should help out.
P. 884#138-140 (I messed up and wrote 141 in hours 1-3 - oops!)
Tomorrow we'll continue with more notes and hands-on using series and parallel circuits, go over the homework problems, and learn to use Ammeters (measuring current)
