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

2 Unit 4F: Circuits and conductors

3 Useful Words Battery Bulb Buzzer Motor Break Electrical insulator
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 Unit 4F: Vocabulary

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

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

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

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

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

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

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

11 Unit 4F: 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? Unit 4F: Changing circuits: L.O. 11, 12, 13, 14: N.C. 4.1a

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