Magnets are the strongest at the poles Magnets have two poles, north-seeking and south-seeking When a magnet is freely suspended it will point to the north Magnet's like poles repel and unlike poles attract A compass needle is a magnet An electromagnet if made with a coil of current-carrying wire wrapped around an iron core You can magnetize and demagnetize magnetic materials Magnets are used in motors and generators, as well as other daily uses Lesson Plans Lesson 1 Stick To It Objectives: The student will: Conduct simple investigations Understand some magnet usage in everyday life Make predictions Record predictions and fact-finding data Verbalize ideas in whole group and small group Work cooperatively with a partner Make a Science Journal about magnets Materials: 1 large chart paper for class observations 1 large chart paper for KWL 14 pencils and recording sheets 27 Science Journals for magnets Helpful Hints: Discuss the importance of handling magnets carefully.
