Do now! Can you continue the sheet you started last lesson? (“Another current model”)
Current Electricity 1. What is Electric Current? Electric current is the flow of electricity through a conductor. The current is caused by the movement.
Can you get the bulb to work? Each of you will get one bulb, one wire, and one battery. Your goal is to get the bulb to light. Easy right? When you find.
