Science 2nd grade | UNIT 5: Electricity 5.3 Making a circuit
149 3 years ago
The electricity from cells is less powerful than mains electricity. Small cells are safe to use. Touching the metal parts will not give you an electric shock.
A cell pushes electricity around a circuit. It has a positive (+) side and a negative (-) side. The bulb lights up when electricity goes through it. The wire is used as a connector.
Activity 5.3 (Can you make a bulb light up?)
You will need: a cell - a cell holder - a bulb - a bulb holder two or more wires
Try making a circuit. You will need to connect the cell to the bulb using wires. Does the bulb light up?
This working circuit makes a loop. Electricity comes out of the cell at the negative (-) end. It moves around the loop in the metal part of the wire then it goes back into the cell at the positive (+) end.
