All Together Now!

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

Objectives

It’s time to put it all together and construct your electric personality. It will have a switch and working electrical components. Follow your plan as far as you can but don’t be afraid to make adaptations and improvements. You will also play an active team game to revise some of the concepts and vocabulary you have learnt on the theme of electricity.

Science Objectives
i) Construct a simple series electrical circuit, identifying and naming its basic parts, including cells, wires, bulbs, switches and buzzers.

Working Scientifically

  1. Identifying differences, similarities or changes related to simple scientific ideas and processes.
  2. Using straightforward scientific evidence to answer questions or to support their findings.

Other Curriculum Areas

Design and Technology - Make/Technical Knowledge

  • Select from and use a wider range of tools and equipment to perform practical tasks [for example, cutting, shaping, joining and finishing], accurately.
  • Select from and use a wider range of materials and components, including construction materials and textiles according to their functional properties and aesthetic qualities.
  • Apply their understanding of how to strengthen, stiffen and reinforce more complex structures.
  • Understand and use electrical systems in their products.

You Will Need

Provided Resources

  • A game sheet for each team of 3-4 children
  • Equivalent number of answer sheets

Additional Resources

  • All the resources set aside to use in their electric model plus some extra recycled packaging
  • A collection of other materials to use for the modelling task
  • PVA glue in pots with spreaders
  • a hot glue gun
  • Strong adhesive tape, masking tape & electrical insulation tape
  • Plenty of stranded electrical wire
  • a craft knife and cutting mat
  • sticky tack
  • a pair of compasses
  • Children’s named project bags and their planning booklets from Session 4
  • All the electrical components set aside plus a few spares for adaptions and changes of plan

Lesson Planning

Teaching

  • Construct an electrical circuit to perform a planned function within a working model including a switch.
  • Solve problems and make adaptations during the making process to overcome difficulties using knowledge of series circuits.


Activities

  1. Play an active team game to revise some electrical concepts and vocabulary (Yrs3&4)
  2. Construct a working electrical model from their own plan and adapt it where necessary to overcome problems (Yrs3&4)
  3. Learn how to create secure wiring for a durable electrical device (Yrs3&4)


Investigation
Design your electric personality Decide which electrical components you will use and what will work on your personality. Design the appearance of your personality – facial features, hair and accessories. Paint a paper plate that will become the face (exploring, pattern seeking, fair testing)
Year 3 – Create the circuit they would like to use with components and draw a circuit diagram to record how they will do it.
Year 4 – Draw a circuit diagram to show what will work, then test it out with electrical components

Vocabulary
Electricity, circuit, switch, pressure, battery, device, motor, bulb, buzzer, component, wire, lead, crocodile clip, connection, power, cell, energy, flow, current, conductor, insulator, disconnect, design, test, adapt, modify
