This is an activity about magnetism and magnetic forces. Learners will explore objects to which a magnet is attracted or repelled, and investigate the attractive and repulsive forces of two like and two unlike magnetic poles. This is the first...

This is an activity about magnetic fields. Using iron filings, learners will observe magnets in various arrangements to investigate the magnetic field lines of force. This information is then related to magnetic loops on the Sun's surface and the... (View More) magnetic field of the Earth.

Students will test various materials to determine if any can shield their "magnetometer" (compass) from an external magnetic field using their own experimental design. If no suitable material is available, they will devise another method to protect... (View More) their instrument. Includes background science for the teacher, worksheets, adaptations and extensions. Next Generation Science Standards (NGSS) are also identified. (View Less)
