High schoolers explore electrical resistance through various experiments. For this physics lesson, students calculate resistance using a mathematical formula. They explain how colors identify the resistance value of a resistor.

Students explore electricity by conducting a series of experiments. In this physics lesson, students discover the relationship between current, voltage and resistance. They calculate voltage and power in a given system.

Students create a 3D vector field map of an electric field. In this physics instructional activity, students measure the voltage inside an aquarium with water. They present their findings and map to class..

Students explore series and parallel circuits. In this physics lesson, students construct a simple circuit and measure its maximum current. They construct their own voltmeter and ammeter that operates at a specified range.

Groups work together to design a lighthouse, from designing and drawing the wiring diagram, to creating prototypes of the switch and circuit, to envisioning and building a scale model along with a blueprint. By including different...

Students explore static electricity using the Van de Graaff generator. In this physics lesson, students construct their own Van de Graaff using simple materials. They explain how charges accumulate on this device.

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.
