Magical Magnets!

Before vacation Mr. Musselman of the Burlington Science Center was in to visit the kindergartners and shared  his magnet program with us.  We learned how strong magnets can be and discussed many of their uses. Through some scientific exploration we determined that magnets stick to metals like iron, and nickel.  He showed us many different kinds of magnets (such as bar, horseshoe and circular) and told us various stories about them.  We learned about electromagnets. These need electricity to become magnetic. The pull of an electromagnet is only temporary. 

Mr. Musselman challenged our thinking with a few questions.  He asked if size matters.  Are bigger sized magnets stronger than smaller magnets. We also discussed pull and attraction compared to a push and repel and observed magnets with same and opposite poles.
