Students will complete four experiments to investigate how magnets will both attract and repel other magnets.

1-Use science process and thinking skills.
Invitation to Learn:
Show the simple demonstration of attraction and repulsion using two bar magnets. Place one magnet on the table and then slide the other magnet towards it. The magnet will either be attracted or repelled. Ask questions like: Why are the magnets pulled together or pushed apart? What will happen if I turn the magnet around? Have the students explain what they already know about poles and the principles of attraction and repulsion.
Any or all of the following four experiments may be done as class demonstrations, or set up into “stations,” where the students rotate from one to the other.
Conclusion: Magnets will both attract and repel other magnets.
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.
