Induced EMF in a Coil Wire
Small groups investigate the interaction between a coil of wire and a magnet to create an electromagnetic field and observe the voltage they create. Through further interactions, they realize a conductor can be charged from the...

Oranges and Batteries
Orange you glad you can make circuits using fruit? Young electricians learn about electric circuits and electricity. As part of the activity, they build a circuit with an orange and then with a banana.
Illustrative Mathematics
Equations and Formulas
Your class is asked to use inverse operations to solve eleven equations for unknown variables or to rearrange formulas to highlight a quantity of interest. By using the same reasoning as solving one- and two-step equations, algebra...
