Investigating Magnetism
Some materials are magnetic and others are not. You are going to predict and
then investigate which materials are magnetic and which are not.
You will need:
• A pencil
• Pennies
• A book
• Paperclips
• A drinking bottle
• A glass jar with a lid
• A wooden ruler
• Pair of scissors
• A drink can
• Safety pin
• A wooden spoon
• A scarf
• Hairgrips/slides
• A range of magnets

Your Investigation
You need to make sure your investigation is a fair test. That means you
only change one part of the investigation when testing something. In this
case, you will change the material you are testing.
Instructions
1. Arrange the objects in front of you.
2. Write the names of the objects on the recording
sheet.
3. Before testing each object, think about whether it will
be attracted or not attracted to the magnet, or
repelled.
This is called making a prediction. Write your
prediction
in the correct column.
4. Test your prediction and write down your
observations.
5. Write a conclusion at the end of the investigation.

Attract or Repel
Look at the list of objects
below and decide whether they
will be attracted or repelled by
a magnet:
Use this Venn diagram to
help you sort out your
ideas.
• paperclip
• a rubber cork
• a rubber
• a plastic pen
• a drawing pin
• an aluminium can
• some iron fillings
It will be
attracted by
the magnet
It will not be
attracted by
the magnet
I’m
not
sure

Building upon the activity the students will be asked
the following questions-
Q - Did all the materials stick to the magnet stick?
Q - Is there anything common in all the objects that
were attracted to magnets?
Q - What are the materials which got attracted to
magnets?
