Compasses and Magnets -

 Levi wondered whether the arrow of a compass will point towards a magnet instead of North so we borrowed a box full of mini compasses to see what would happen next.  We started to think and talk like scientists.  This is what we did:

Everyone got a piece of paper and we got a mini compass each.  We placed the mini compass on the paper. 

We also had 3 big compasses and a giant red magnet.  Levi used the giant red magnet on one of the big compasses and the arrow of the compass did point to the magnet instead of north.  When he used the other end of the magnet it pulled the other end of the arrow.

Everyone got a silver magnet and put it on the side of the compass and moved it around the compass. The arrow moved with the magnet.  We tried it using black magnets and it worked.  

Then we used coloured magnets.  We found that the green, red, blue, purple and yellow magnets were a mixture of negative or positive.  We had some odd magnets and one side attracted red and the other attracted the white needle. 

Toby suggested we put all of the mini compasses on a sheet of paper and see if they would all point north.  They didn't.  Then we got the giant magnet and move it around the outside of the compasses.  Jarvis said they were definitely interacting.  Nevadah said it was very satisfying.  

We think need to explore more about magnetism.
