It’s Electric

Science Year 3/4
This unit is part of Year 3/4 Science Electric Personalities

Objectives

We use electricity every day of our lives to help us with almost every task we do. Look at a selection of devices and appliances and explore the many different functions they have. Learn some fascinating electrical facts by playing a game and design posters and leaflets to help people stay safe when using electricity.

Science Objectives
i) Identify common appliances that run on electricity.

Working Scientifically

  1. Asking relevant questions and using different types of scientific enquiries to answer them.
  2. Identifying differences, similarities or changes related to simple scientific ideas and processes.

You Will Need

Provided Resources

  • Card zone labels
  • Exploration Sheets

Additional Resources

  • 3-4 plug in appliances that do different jobs, e.g. hair drier, kettle, lamp, CD player
  • 3-4 different battery powered toys, e.g. push-button baby toy with sounds, toy vehicle, Karaoke machine, light up toy
  • Selection of 6-8 different cells (batteries) - size, shape, voltage
  • 3-4 torches each disassembled with all parts including the batteries in a sealable plastic bag or lidded tub
  • 3-4 battery powered devices, e.g. fairy lights, hand held fan, book light, radio
  • Paper, pens, pencils, felt tipped pens

Lesson Planning

Teaching

  • Explore a variety of electrical items and begin to ask questions, look for similarities and differences and form ideas and theories.
  • Learn some basic scientific facts and vocabulary about electricity as an energy source.

Activities

  1. Actively explore some electrical appliances and devices to ask questions and begin to answer them (Yrs3&4).
  2. Play an active electrical guessing game to learn basic electrical concepts and vocabulary (Yrs3&4).
  3. Create either a poster (Yr3) or a leaflet (Yr4) explaining the dangers of electricity.
  4. Play a memory game to highlight the versatility of electricity as a power source (Yrs3&4).

Investigation
Introduce the outcome – by the end of the block you will create your own electric personality – a person or robot that is powered by electricity. But first you will need to become an expert on electricity. Investigate electrical components and identify items that run on electricity – both mains and battery power. (exploring, classifying and identifying, analysing secondary sources)
Year 3 – Draw and illustrate 3 facts about electricity
Year 4 – Draw and illustrate 5 facts about electricity.

Vocabulary
Electricity, cell, battery, plug, mains, cable, appliance, device, connection, power, danger, safety
