Week 2: February 16th, 2011

This week we went more in-depth into basic circuit design. First we played a game by making a human circuit.  One person acted as a switch telling the circuit to turn on or off, another as a battery which sent electricity (in the form of hand squeezes) and the rest of the girls were wires passing electricity throughout the circuit.

Next, we built a simple circuit using a light bulb.  We made the circuit progressively more complicated by adding switches and multiple light bulbs.  We even learned the difference between a series and parallel circuit and the situations where one is better than the other.  These girls have an amazing knack for understanding how electrons create electricity and the effect of circuit design on electric current!

Finally, we listened to a presentation by Morse School 8th graders who were in the process of using their circuit design skills to develop robots for a competition.
