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...

My friend told me how electricity is measured and I was like Watt! In the hands-on activity, learners explore electricity by building circuits, both parallel and series. They also determine how increasing the number of light bulbs and...

Students investigate the properties of capacitors and discover that capacitors block DC and filter AC. They discover the function of capacitors. Students differentiate between AC and DC power. They explore the role of resistors.

Light and sound go hand in hand. Pupils set up a system that will emit sound when a laser is directed at a photodiode. Various objects, such as a comb and talcum powder, allow for modulation of the laser beam. Individuals also...

Students investigate the properites of a semiconductor device known as a diode. They recognize a diode as a one way conducting device. They describe alternating current and the use of a diode to convert it to direct current. Students...
