Magnets vary in strength, with strong magnets creating larger magnetic forces
Magnetic forces can act at a distance, so magnets do not need to be touching to exert a force
Scientists ask questions and then plan how to carry out the right type of investigation to find answers
The results of a scientific investigation can be compared to other investigations that have been carried out

Larger magnets are always stronger than smaller magnets.

Explicit teaching as well as opportunities for children to explore different size magnets and their strengths.

Strength - The strength of something is shown by how well it can withstand a force or pressure.
Magnetic force - Magnetic force is the force caused by a magnet.
Material - The material is the thing that objects are made from such as wood, metal or plastic.
Distance - The distance between two points is the length of space between them.
Compare - We compare things by looking at what is the same and what is different.
