Opening the switch means breaking the circuit.

If you have too many cells in a circuit, the bulbs burn out.

Electricity is the flow of uncharged particles.

A cell has two positive terminals and one negative terminal.

Electric current needs a continuous path.

Electricity can flow many directions in a circuit.

When you make a complete circuit with two cells, you must always put the (+)terminal of the cell to the (+) terminal of the other cell.

Drawing pins are electrical components.

Plastic coating around the metal wires prevents from being electro-cut.

The electricity can jump from one component to others in a circuit.

If the electricity doesn't have a path to travel on, it stops.

Flat cell means a cell has used up all the chemicals.

When we close the switch, the light will shine.

We need to strip the plastic off the ends of the wires to flow electricity in a complete circuit.

If your circuit has a gap, the electricity can jump over it and can flow through all the components properly.

You can make a stronger cell by joining two cells together.

When we remove one bulb from a circuit, the other bulbs can shine more brightly.

The switch turns the electricity on and off

When we turn off the light, the circuit break.
