Electric Analogies
We can see the result of electricity but not the process itself. The simulation compares electric circuits to a water tower and water wheel cycle. Young scientists adjust the height of the tower, the amount of resistance, and if...

Circuit Math
Seven circuits are spread over three pages. One is a parallel circuit, one is a series circuit, and the rest are combinations. Emergent electrical engineers solve for current, voltage, or resistance. They fill in a chart for each...
Curated OER
Series and Parallel Circuits
Electricians draw four different circuits and answer questions about the resistance, voltage drop, and current at different points in each. Completing this worksheet will help make sure that your class is understanding what is happening...
Curated OER
Casual Patterns in Simple Circuits
Students work in cooperative pairs to create a series circuit and a parallel circuit. Students compare and contrast the two different types of circuits using worksheets that are included.
Curated OER
Ohm's Law I
High schoolers work to increase the intensity of a light bulb by testing batteries in series and parallel circuits. They analyze Ohm's Law, power, parallel and series circuits, and ways to measure voltage and current.
Curated OER
Batteries in Series
Eighth graders examine batteries in a series circuit and the associated voltage. They determine, through inquiry and problem solving, that the total voltage of batteries in a series is the sum of the voltage of each battery. They design...
