Today the kids and I designed a "conductor tester." We did this by creating a circuit that could be opened with two wires. If the two wires touch each other or an object that is a conductor, the circuit would be complete and the motor would run. Students went around the room with their testers and founds lots of conductors and insulators. Do you know what kinds of materials are conductors and insulators? Here are a few pictures of our young scientists at work...
Here's a picture of Lizzie with our high-tech conductor/insulator tester.
Sloan is testing out the top part of a clipboard.
Xion found out that the front of a stapler is a conductor.
