Forces and Magnets
We have had to use our Super Powers of collaboration and co-operation to work in a team to study the effects of friction on a bottle top. One was covered with sandpaper and one was left smooth. We found the bottle top covered in sandpaper did not travel as far as the smooth one. We concluded that the rougher the surface the greater the force of friction.
Today we investigated the non-contact force of magnetism. First we predicted which objects in our bag were magnetic then we tested our ideas. We had to use observation. We were surprised by some of our results. Not all metals are magnetic!
