Solar Array
by Victoria Rackley
This lesson is focused on solar energy, students engage in a hands-on exploration of photovoltaic cells, motors, and light bulbs to investigate the correlation between light intensity and solar power generation. Beginning with an introduction to photovoltaic technology, students learn how solar cells convert light into electrical energy. They then assemble a simple circuit comprising a photovoltaic cell, a small motor, and a light bulb. By varying the light intensity using adjustable lamps or sunlight at different times of day, students observe how changes in light intensity affect the motor's speed and the brightness of the light bulb. Through this experiment, they gain a practical understanding of solar energy's dependence on light intensity and its application in renewable energy systems.

The purpose of this lesson is to introduce and apply the concept of frequency. Students will begin by a motivating “click the mouse” challenge. This will help them to develop the concept of frequency
