This lesson, presented by the National Nanotechnology Infrastructure Network, covers magnetism. Students will experiment with ferrofluid which is "a unique material that has both magnetic and liquid properties. It is a colloidal solution of nano-sized particle of magnetite suspended in a liquid." A...

In this activity from the Stanford Solar Center, students learn the basic principles of magnetism and how they apply to the sun. The activity is intended for high school students who have taken or are taking pre-calculus and the activity should take three class periods to complete. A printable...
