Check out this experiment we did with the magnetite we found at the beach the other day. If you don’t know, this mineral has the highest level of iron which makes is a lot of fun to experiment with! Check out more information on this mineral on geology.com. We were amazed by the patterns and responsiveness of the tiny bits on the tray!! We also tried putting it in water to see if it responded differently.
We moved on to conduct a density experiment using oil, corn syrup and 2 temps of water and a neodynium magnet… The density of the liquids definitely had an effect on how strong the magnetic forces were!
