Forces, Magnets and Springs in Oystercatchers

Posted on

This term in Science we have been learning about forces. We have started off by looking at different push and pull forces that can be applied to springs and the effect this has on them.

We have also been learning about magnetism and materials that are magnetic. We learned about the different poles on magnets and then side-tracked into discussions about Chinese high-speed trains, the centre of the Earth, homing pigeons and the Northern lights! All related to magnets of course.

The experiments we conducted showed that only certain types of metals are magnetic (iron, steel, nickel and cobalt) and that a bigger / heavier magnet is not necessarily the strongest. We also learned we could temporarily magnetise paperclips by rubbing them on a magnet for a few seconds.
