Students will discover through hands-on activities that magnets have the ability to push and pull iron objects without touching them.
Magnets by Janice VanCleave

The Magnet Book by Shar Levine and Leslie Johnstone
1-Use science process and thinking skills.
2-Manifest scientific attitudes and interests.
Invitation to Learn:
Demonstrate to the students the “flying” paperclip (a paper clip attached to a string taped to the table is suspended in mid-air by a bar magnet). Ask questions like: Why is the paper clip suspended in mid-air? How many other things can you attach to a string and suspend with a magnet? Does using a circular magnet alter the experiment? How about a horseshoe magnet? How about this nail?
Magnets have the ability to push and pull iron objects without touching them.
Have the students design their own types of games to demonstrate the difference between magnet types and their abilities to pull or push iron objects without touching them. Suggestions: fishing poles with various magnets attached to pick up iron objects from a bucket; a paper racetrack where student-designed cars with paper clip bottoms are pulled around with magnets beneath the track; a homemade version of an Etch-A-Sketch using iron filings and acetate sheets.
This lesson is part of the Fifth Grade Science Teacher Resource Book (TRB3) http://www.usoe.org/curr/science/core/5th/TRB5/. The TRB3 is designed to be your textbook in teaching science curriculum to your students. This book covers all the objectives of each standard and benchmark. If taught efficiently, a student should do well on the End-of-Level (CRT) tests. The TRB3 is designed for teachers who know very little about science, as well as for teachers who have a broad understanding of science.
