Let’s Get Started… Activity: • Are these objects conductor or insulators of electricity? • What is your evidence? Stretch it : What about heat? • Are conductors of electricity always • conductors of heat? What is the evidence? • End

Big Question: 03/07/202 How do we measure electricity? 0 To develop knowledge by stating the meaning of complete circuit, ammeter and current. To secure understanding by using the idea of a complete circuit to test conduction of electricity To achieve excellence by constructing circuits Key Word: circuit – a complete and from instructions in a closed path around which a circuit diagram. circulating electric current can flow

Prepare Agree L.O.s New Info Apply Construct Review Measuring current • Current is a movement of electrons around a circuit. • The more electrons (charge) the bigger the current. • It is measured with an ammeter • It is measured in Amps which have the symbol A

Prepare Agree L.O.s New Info Apply Construct Review Rules for making circuits • If the circuit does not work then check: a) Matches diagram? b) Short circuit? c) Swap bulb. d) Gently move. e) Swap wires one at a time
