Science 9 – My science 9 students are now working with circuits in the electricity unit. I’m following my own modified version of the CASTLE curriculum. The first step for the students is to identify what materials are conductors and insulators, and to use some type of circuit setup to test for conductivity (battery, three wires, and a light bulb).
After today students have the model that a continuous loop of conductors makes a circuit while an insulator will prevent a circuit from working. In a few days we will try to break this model!
