1 Unit 4F: Simple circuits: L.O. 1, 2: N.C. 4.1a Unit 4F: Circuits and conductors

2 Circuits and conductors

3 Unit 4F: Vocabulary Useful Words Battery Bulb Buzzer Motor Break Electrical insulator Electrical Conductor Metal Plastic An electrical energy source A light source powered by electricity A sound source powered by electricity A device that uses electricity to produce movement In an electric circuit a break will stop the circuit working A material that will not allow electricity to pass through A material that will allow electricity to pass through A good conductor of electricity An electrical insulator

4 Unit 4F: Simple circuits: L.O. 1, 2: N.C. 4.1a Unit 4F: Simple Circuits Simple Circuits Which of the circuits will work and which ones will not? Why will they not work?

5 Unit 4F: Safe Experiments: L.O. 3: N.C. Unit 4F: Safe Experiments Safe Experiments

6 Unit 4F: Conductors and Insulators: L.O. 4, 5, 6: N.C. 3.1c Unit 4F: Conductors and Insulators Conductors and Insulators What materials are good conductors of electricity? How can we test various materials to see if they are conductors? MaterialConductorInsulator What do the results show? Are there any exceptions to the general rule?

7 Unit 4F: Uses of metals and plastics in electrical circuits: L.O. 7: N.C. 3.1c Unit 4F: Uses of metals and plastics in electrical circuits Uses of metals and plastics in electrical circuits

8 Unit 4F: Switches: L.O. 8: N.C. Unit 4F : Switches Switches What does the switch actually do?

9 Unit 4F: Switches: L.O. 8: N.C. Unit 4F: Switches

10 Unit 4F: Varying components: L.O. 9, 10: N.C. 4.1b Unit 4F: Varying components Varying Components

11 Unit 4F: Changing circuits: L.O. 11, 12, 13, 14: N.C. 4.1a Unit 4F: Changing circuits Changing circuits How can you change the brightness of the bulb? List all the things you could change to do this. What will happen if you add more bulbs to the circuit? What would a switch do to the circuit? If the bulb was exchanged for a motor, how could the speed of the motor be changed? How could the loudness of a buzzer be changed?

12 Unit 4F: Summary Concept Map Circuits and Conductors Circuits Insulators Do not allow electricity through Non-metal Needs to be complete Need a power source Components Conductors Allow electricity through Some better than others Metals are good Cables Wires Switch can break a circuit More Less Buzzer quieter Motor slower Bulb dimmer Buzzer louder Motor faster Bulb brighter Batteries
