Today students watched a demonstration comparing the different strengths of a bar, horseshoe and ring magnet. Ms.J set out the magnets and showed a pile of paper clips, then challenged the 2Js to come up with an experiment that would tell which magnet was the strongest, 2nd strongest and the weakest. After some discussion, they decided that the magnet that picked up the most paper clips would be the strongest. Students first made predictions of how many paper clips each magnet would pick up, and then recorded the actual amount onto their graphs. It turned out that our bar magnet was the strongest, the ring magnet was the 2nd strongest, and our horseshoe magnet was the weakest. Check out our slide show of our experiment and graphs to show our understanding!
