This will be
a hands-on lesson with plenty of magnets for each child.
Introduce 5 experiments and organise pupils in groups.
are attracted by a Magnet?
the magnetic and non-magnetic objects in a shoe box. Test for magnetism,
observe and record results of those objects attracted and those
not attracted by a magnet, in the science copies.
2 Bar magnets and a table
magnet on the table. Slowly bring the other towards one pole of
the magnet on the table. If the free Pole moves away, you were trying
to bring similar Poles together. Similar Poles repel each other.
If the magnet pulled together, the opposite Poles were attracting
Strength of Magnets
Three different bar magnets, paper clips
bunch of paper clips on the table. Count the number of clips one
magnet will pick up before the clips start dropping off. (The clips
must form a chain). Test with other magnets. The strongest will
pick up and hold the most clips.
Bar Magnet, Steel Needle
needle with one Pole of the magnet, always in the same direcction.
Lift the magnet well away from the needle at the end of each stroke.
(This gives well-defined North and South Poles). Continue stroking
for five minutes, then test your new magnet.
a Magnetic Field
A4 sheet, glue,iron filings, bar magnet
glue over the paper, then sprinkle some iron filings on the paper.
Place a bar magnat under the paper. The iron filings will spread
out to create a magnetic field.

Set up laptop and data projector. Insert CD Science Explorer II.
Go to Catalogue and scan for 'Magnets'. Using the second CD Science
Explorer 26 go to 'Compass', then 'Forces and Motion' and then to
