Posts Tagged ‘Series Circuits’
This mini-lab worked out really well. In fact, quite of few kids surprised me by getting into building circuits. I know a lab goes well when nobody bails or gives up in frustration.
I introduced series and parallel circuits with three quick overheads. I also taught them the schematic symbols for a battery, switch, and bulb. I helped them out by drawing the schematic for the first problem. The attached document is pretty much self-explanatory, but I would suggest you have the kids read the last couple questions before they start building.
I had the kids in groups of two. Each group needed a 3v battery pack (2-D cells), two light bulbs in holders, two knife switches, and about 6 sets of alligator jumpers. You could use pre-cut wires, I had the jumpers available.
With the introduction to series and parallel circuits, the lab took the entire class period to complete.
