Circuits
April 16, 2008 by Brad Edwards
This morning we spent about 3o minutes working on a math manipulative site. The students were engaged, and seemed to enjoy the experience. For the last half hour, I sent them all to a site for a basic circuit construction kit. http://phet.colorado.edu/new/simulations/sims.php?sim=Circuit_Construction_Kit_ACDC We made simple circuits using the light bulb, a knife switch, a battery and wires. Then it got interesting. We added an ammeter in line, a second light bulb, a third, and watched what happened to the ampere reading. There were only a few fires or short circuits. The students were again engaged, and I think did really, really well. Oh, by the way, these are first graders!!
