Magnets

For the past three weeks our class has been studying magnets! We have been reading books and conducting experiments to discover many of the fascinating ways that magnets work! We learned about types of magnets and how magnets attract and repel. Children experimented to discover that magnets are strongest at their poles, a small magnet can sometimes be stronger than a large magnet, and only some types of metals attract to magnets. We also learned that the earth is a giant magnet! During certain experiments we practiced predicting the outcome before we conducted the actual experiment. Students predicted which objects would "stick" to their magnet and which objects could be placed between a magnet and a paper clip without preventing the magnet from attracting the paperclip. Our book of experiments is coming home tonight so you can see many of the things we learned! We had so much fun with this unit! If you ask, your child should be able to tell you the meaning of the vocabulary: magnet, attract, repel, north pole, south pole, compass, and force.

I have added new photos to our magnet experiment slideshow, so even if you have seen it before, give it another look!
