Wednesday afternoon, Mr. Musselman of the Burlington Science Center was in to visit Room 101 kindergartners and shared his magnet program with us. This was a culminating event to revisit was was learned during our Push and Pull Science Unit. We learned that magnets can push and pull and that a force or motion can move something. 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.
