Lesson Details
Key learning points
- Magnetic forces are forces caused by magnets.
- Magnetic forces are non-contact forces. A magnet can act at a distance so it does not have to be touching the object.
- Scientists make observations and measurements about the world to help them to find out more about things.
- Magnetic force can be observed and measured acting at a distance.
Common misconception
Magnetic force is a contact force.
Through their own investigation, children will demonstrate magnetic force acting at a distance.
Keywords
Magnetic force - Magnetic forces are forces caused by magnets.
Non-contact force - Non-contact forces occur when the objects are not touching.
Distance - The distance between two points is the length of space between them.
Observe - To observe is to look very closely and use other senses too.
Measure - To measure is to use equipment to find numbers to describe a feature of something such as its length, weight, size or time.
