Eighth Graders Light Up the Halls

The second STEM activity this semester challenged the eighth graders to construct and wire a model for electricity. They were required to design a structure with at least one working light bulb, a circuit, and a power source that is activated by an external switch. Computerized drawings of the profile, circuitry, and calculations for voltage, resistance, and current accompanied each structure. After seeking approval for each design, students worked in cooperative teams to present their model.
