Make a Light Bulb
Could you reinvent the light bulb? Scholars tap into their inner Thomas Edisons to build a light bulb prototype out of a jar and some wires. They see how long the filament wire glows in the jar (batteries not included) to measure their...

How Photocells Work
Give small groups of physical scientists tokens that represent electrons in a photovoltaic cell. They play a dice game in which they move the tokens around, representing the flow of electrons through the p-n junction of a semiconductor...
LABScI
Circuits Lab: Lightbulbs
Electrons flow from negative to positive, but the general consensus is that current flows from positive to negative. Scholars explore current through construction of circuits in both series and parallel. The focus is on voltage,...
