Magnetic fun time

Science Year 3
This unit is part of Year 3 Science Amazing Magnets

Objectives

Play a fast paced game to practise your knowledge of whether magnets attract or repel each other depending on which poles are facing. Devise an exciting activity on magnetism to fascinate visitors to the science fair.

Science Objectives
i) Predict whether two magnets will attract or repel each other, depending on which poles are facing.

Working Scientifically

  1. Use straightforward scientific evidence to answer questions or to support findings.

Other Curriculum Areas
Maths - Measurement

  • Estimate and read time with increasing accuracy to the nearest minute. Record and compare time in terms of seconds and minutes.

You Will Need

Additional Resources

  • 40 cardboard red/blue bar magnets with either Attract or Repel written on the reverse of each
  • A large selection of different magnets
  • A large selection of craft resources
  • Magnetic items, e.g. metal bearings, paperclips, paper fasteners, bulldog clips, a selection of copper and silver coins
  • Stop watches and sand timers of different time lengths (e.g. 1, 2 and 3 minute types)
  • Garden canes and string – to make magnetic fishing rods
  • Large tub/tank of water and items to put in it to create boat course

Lesson Planning

Teaching

  • Revise and reinforce knowledge of attraction and repulsion between magnetic poles through participation in an active game.
  • Devise and prepare activities (for visitors to a science fair, that use magnetic force.

Activities

  1. Play a game to revise and reinforce knowledge of how magnets attract and repel depending on which poles are facing.
  2. Work in a group to devise a magnetic game or challenge for visitors to a science fair.
  3. Assemble and make resources to run activity including signs to introduce the challenge.
  4. Consider what each activity will teach visitors about magnetism.

Investigation - exploring
Develop a game or activity that uses magnetic forces by trying out a variety of ideas.
