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...
Exploratorium
Short Circuit
Though not commonly searched for, this is a vivid demonstration of how a fuse can be blown, or rather, how resistance works in an electric circuit. You will basically set up a circuit with no lights or bells or motors, allowing the wire...

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...
National Nanotechnology Infrastructure Network
Hiding Behind the Mask
Microchips are a man-made wonder. Investigate the manufacturing wonder with a hands-on inquiry-based lesson. Scholars simulate the process of pattern transfer using photoresist. Their conclusion identifies how their process replicates...
Curated OER
Design Project: Audio Power Amplifier
