To be able to identify whether or not

To be able to identify whether or not a bulb will light in a circuit. Success Criteria • *To be able to identify whether a lamp is connected or not. • ** To be able to explain what allows or prevents the lamp from lighting. • *** To be able to identify how to fix incomplete circuits. What would happen if we did not have any electricity? What would the limitations be?

Retrieval practise Yellow- Mild Blue- Medium Red- Fiery What is a switch? What are components? Name 3 types of switches. What is electricity? Name 3 different components. What is a bulb?

Answers A switch controls the flow of electrons in a circuit. Components are the parts of a circuit. The flow of particles called electrons. Bulb, crocodile clip, battery, switch. Toggle switch, key switch, slide switch, pull switch, selector switch, paddle switch. A component which lights up when there is a flow of electrons.

How can electricity be used when thinking artistically? Could you make a dance to represent electricity? Or some artwork?

Glossary for this lesson: Circuit Paths or lines through which electrical currents flow. Current The flow of electric charge. Electricity The flow of particles called electrons. Electron A very small particle that moves around an atom. Components The basic parts of a circuit. Lamp A component which lights up when there is a flow of electrons.

Recap from previous learning The images below show the different types of switches that we looked at last week. Can you remember the names of any? Can you identify where you might find these switches in your house?

Complete and Incomplete Circuits will only allow a flow of electrons when they are complete. If there is a break in the circuit, the electrons cannot flow and the components will not work. This concept is explained further in a video on the next slide.

Watch this video. This shows how to identify whether a circuit will work and light up the bulb. https: //www. youtube. com/watch? v=KYKVf 6 edvc. A&feature=youtu. be

Task Look at the circuits on the next slides. For each, predict whether the bulb will light or not. Challenge: explain how you know you are correct! If the circuit will not work, can you explain how to fix it?
