Magnetism and Nanotechnology: Exploring Ferrofluids

This lesson, presented by the National Nanotechnology Coordinated Infrastructure, covers magnetism. Students will experiment with ferrofluid which is "a unique material that has both magnetic and liquid properties. Ferrofluid is a colloidal solution of nano-sized particle of magnetite suspended in a liquid." A Teacher Preparation Guide, Student Guide, and Next Generation Science Standards for the lesson are included.
