GRADES K - 8
MAGNETS

OBJECTIVES: Students learn about the science of magnets and how magnets work. Students are introduced to a variety of devices which use magnets (compass, alarms, salvage lifting magnets). Students conduct a series of fun experiments. Students magnetize objects and demonstrate how magnetism operates right through other materials. NATIONAL SCIENCE STANDARDS: Physical Science: Light, Heat, Electricity, and Magnetism (K-4) Transfer of Energy (5-8) Science And Technology Standard: Understanding About Science And Technology STANDARDS FOR TECHNOLOGY LITERACY: The Nature of Technology: Students will develop an understanding of the core concepts of technology. Students will develop an understanding of the relationships among technologies and the connections between technology and other fields of study. The Designed World: Students will develop an understanding of and be able to select and use information and communication technologies.
