Physics: Circuits are cool!
Today's experiment was originally called: "Experimenting with different kinds of circuits," but about 5 minutes into it, the kids decided to change the name to "Circuits are cool." We did, and they are. The kids learned about the parts of a circuit: battery, load, and wires, and they were challenged to build circuits that could turn on light, motors, and annoying beeping machines. What's that saying...necessity is the mother of invention? Following their success with the annoying beeping machines, we introduced the concept of switches. Ah....sweet silence. Afterward the kids recorded their results in their lab-books using circuit diagrams.
