Produced by the Discovery Channel, Understanding: Magnetism shows students that without magnetism we would not have music as we know and experience it today; we would not have computers, motor vehicles, compasses, or MRI scans. Magnetism literally shapes our modern-day world. Learn how magnetic forces were first discovered and how magnetism affects both humans and other animals. Explore the role of magnetism in computers, audio recording, medicine, and travel. After viewing this program students will better understand that only certain materials can be attracted by a magnet, that those materials contain iron, that magnetism is caused by the behavior of atoms in a magnet and more. They will be able to discuss the idea of magnetic reversal, the idea of integrating different disciplinary areas of science toward a common goal, why bacteria and animals who use magnet field lines for navigation is useful and many other related topics. 52 minutes. Includes teacher guide.
