Third graders continued their investigation of magnets. They explored how magnets repel and attract with floating magnets.

Then, we aligned electrons to magnetize a paperclip and created a temporary magnet.

Magnets attract iron which is the 26th element on the Periodic Table and an essential nutrient. We discovered that iron fortified cereal contains pieces of iron. We used a neodymium magnet to pull the iron out of the cereal. Click here for more information.

A compass is a lightweight magnet and the needle lines up with the earth’s magnetic field. Lab partners used these compasses to demonstrate the magnetic field of the magnet they encircled. When we switched the poles, the needles turned. Click here to learn more. Fascinating!
