An electrical switch is used to turn ON and OFF the flow of electricity in a circuit. In the “ON” position, it connects the conductors and allows the flow of current. In the “OFF” position, the switch separates two conductors and prevents the flow of electric current.
Making party lights using circuits and switches
Students learn the basics of electrical circuits and switches by building a simple string of lights. Then using Excel, they choreograph their own light patterns that they can record and present.
Harnessing Electricity to Communicate
Students build a telegraph out of everyday objects to understand electrical energy and its role in communications. Then, they use a customized workbook to send and receive information in Morse code using their telegraph.
