On our second day of studying electricity, we learned how switches affect the flow of electricity in a circuit. As in our previous investigation, students were given a set of materials and asked to discover for themselves. I just asked, "How could you use this switch to make your motor turn on and off?" Using what they learned from our previous experiment, students were able to design a circuit that correctly utilized a switch. It was even more impressive when they were able to explain WHY the switch closed and opened the circuit. They had a great time experimenting and trying out new designs!
We also learned how to draw a schematic diagram. Here's Madison's Science Notebook entry:
