Using magnets to solve problems (non-statutory: Scientists and Engineers)

I can give examples of how engineers use results of science to design solutions and help solve everyday problems.

Lesson details

Key learning points

  1. Humans have found magnets to be useful in their everyday lives
  2. Everyday uses of magnets include compasses, electronic devices and games
  3. Maglev trains do not use an engine because they move forwards using magnets, similar to some roller coasters
  4. Engineers design and build things, using their knowledge of maths and science
  5. Men and women can become different types of engineer. They need to be curious, creative and observant

Common misconception

Engineers are only men and just like to repair or fix things.

Explicit teaching and discussion of the range of engineers and the different skills engineers need.

Keywords

  • Everyday uses - Everyday uses are the ways in which we use things in our lives such as using a kettle to heat water.

  • Electronic devices - Electronic devices are machines of pieces of equipment that are powered by electricity, like computers and phones.

  • Maglev train - A Maglev train is a type of high-speed train which uses magnets to reduce friction forces and to move.

  • Engineer - An engineer is a person who designs and builds things.

  • Design - To design something is to make a plan and a drawing describing how it could be built.

Encourage children to see engineering as a useful job that they could do if they choose to. It requires a wide range of skills and solves global problems.
Teacher tip

Equipment

None required. If you have a stacking ring magnet tower, this could be used to support task B.
