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

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.

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.
