Students compare series and parallel circuits. In this electricity and circuits instructional activity, students roleplay as a "wire" passing an energy ball to demonstrate how a series circuit works and how the circuit can be broken....

Students research on renewable and nonrenewable resources. In this chemistry activity, students design and build solar panels. They evaluate their device and write a lab report.

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 construct a homopolar motor following certain procedures. In this physics lesson, students explain how generators and motors work. They compare and contrast the characteristics of both.
