1. Warm-up 1.List some things that you already know about magnets. 2.Do you think magnets could cause any type of forces or motion? Why? 3.Based on what you already know about electricity, look at the picture. Will the light bulb light up? Why?

2. Energy The ability to do work or cause a change. Energy is never lost or created. It just transfers from one type to another! There are many different types of energy!

3. The CELL The cell stores chemical energy and transfers it to electrical energy when a circuit is connected. When two or more cells are connected together we call this a Battery. The cells chemical energy is used up pushing a current around a circuit.

4. A circuit starts at the source of the electricity and ends at an output device where the electricity is used or released. A switch controls the current as it flows through the circuit.

5. What is an electric current? An electric current is a flow of microscopic particles called electrons flowing through wires and components. + - In which direction does the current flow? from the Negative terminal to the Positive terminal of a cell.

6. Electrons will flow from negative to positive as long as the circuit is complete. –(No breaks or gaps in the circuit)

8. The components are connected end-to-end, one after the other. They make a simple loop for the current to flow round. SERIES CIRCUITS If one bulb ‘blows’ it breaks the whole circuit and all the bulbs go out.

9. PARALLEL CIRCUITS The current has a choice of routes. The components are connected side by side. If one bulb ‘blows’ there is still a complete circuit to the other bulb so it stays alight.

10. An electric circuit needs two main things in order to work: 1. A power source. 2. To be complete.
