One of the best parts of this project is that kids can learn about science while painting. You can use all metal pieces, or you can mix in some things that the magnet can’t move like glass marbles or small plastic items. Observe how each of the metal pieces move differently. Some were too heavy, and some may not move at all.
Magnets are rocks or metals that create an invisible field around themselves. This field attracts other magnets and certain metals. The presence of a magnetic field is why you can cover a metal refrigerator door with magnets. A magnetic field is concentrated around the ends of magnets.
Magnets can either pull toward each other or push away from each other. Grab a few magnets and check this out for yourself!
When magnets pull together or bring something closer, it is called attraction. When magnets push themselves or things away, they repel.
Magnets work through paper, trays, and paint!
Not all metals are magnetic because they do not contain enough or any Iron, cobalt, nickel, etc. Substances that are not attracted by a magnet are called non-magnetic
