Lesson details

Key learning points

  1. Magnetic forces are forces caused by magnets.
  2. Magnetic forces are non-contact forces. A magnet can act at a distance so it does not have to be touching the object.
  3. Scientists make observations and measurements about the world to help them to find out more about things.
  4. Magnetic force can be observed and measured 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.

Common misconception

Magnetic force is a contact force.

Through their own investigation, children will demonstrate magnetic force acting at a distance.

This hands-on lesson provides the opportunity to awe the children with magnetic force. It would help to fasten the paperclips to thread in advance of the lesson so the focus can be on the science learning.
Teacher tip

Equipment

Magnets, paperclips, cotton thread or wool, sticky tape and rulers.
