Some things are magnetic




This term the junior classes are learning about magnets.

Today they found out that magnets stick to some things but not others.

The things that magnets stick to are called magnetic.

In groups students looked at a collection of objects and guessed whether they thought they would be magnetic or not. These charts show their predictions.



Next the students used a magnet to test each object. These charts show which objects were magnetic and could be picked up by the magnet and which were not magnetic.

We found out that....
  • Magnets stick to some metals but not others.
  • Magnets do not stick to plastic, wood, stone, glass or fabric.
