As part of our study of energy we explored the electrical form of energy with electrical circuits. Students worked with a partner or two to put together an electrical circuit with and without a switch. They had to identify and explain how the switch worked to control the flow of electricity. Students concluded a circuit is essentially a circle and in order for electrical energy to flow from the battery to the light bulb to make it light up, there can’t be any interruptions in the metal on metal connections. The switch causes a break in the circuit, allowing us to turn the light bulb on and off. Here are some photos from our experiment. Lab sheets were sent home last week!
