Level 3 |
I know that electricity will not flow in an incomplete (broken) circuit. I can identify, name and draw components. I know that a bulb will be brighter if you have more cells (battery) in the circuit. I know that if you add more bulbs to a loop (series) circuit they will get dimmer. I know that electricity is convenient, and that it costs money. |
Level 4 |
I can describe an electrical circuit by drawing symbols for the components. I can identify the two ways of connecting circuits. I can describe how bulbs behave in the two types of circuit. I know that energy in circuits can be ‘wasted’. |
Level 5 |
I know the correct name for the two types of circuit (series and parallel). I know how to measure the current in a circuit. I can explain current as a flow of charge. I know that voltage provides the potential for electricity to flow. I know that the current in a circuit can be changed using a variable resistor. I can explain how electricity is generated using different energy sources (e.g. coal, oil, gas, wind, sun). I know that generating electricity can cause pollution. I can give examples of ‘waste’ energy transfer. |
Level 6 |
I know that in a series circuit the current is the same everywhere. I know that in a parallel circuit the current is not the same everywhere. I can describe how a cell produces voltage. I can relate the fact that voltage ‘drops’ across a component to the idea that energy is being transferred to that component. I can give examples of the dangers of high voltage circuits. I can compare the amount of energy transferred in different electrical devices by talking about ‘power’. I can describe other examples of energy transfer. I understand the link between heat energy and temperature. |
Level 7 |
I can explain why the current is different in different places in parallel circuits. I know that current is conserved. I can explain voltage. I can use my understanding of power to work out the cost of using electrical appliances. |
