Lesson details
Key learning points
- 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
Common misconception
Larger magnets are always stronger than smaller magnets.
Explicit teaching as well as opportunities for children to explore different size magnets and their strengths.
