To help us wrap up our study of magnets, Mr. Musselman of the Burlington Science Center was in to visit the kindergartners and shared with us his magnet program. 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.
