Testing Magnets
This week we tested things to see if they were magnetic. We tested nails, screws, rubber bands, copper, cardboard, foam, paper clips, string, different rocks, and pieces of screen. The class took magnets and put them on the objects. We found out that the paper clips, the nails, the screws, the screen, and only one of the type of the rocks stuck to the magnet. Everything else didn't stick. The things that stuck were magnetic. Everything else wasn't. That's how we got our results for this 4th grade experiment.
