Then they should tie a magnet at the end of their string as bait. Now it is time to fish. Have students lower their rod into the pond. Then ask the children what didn't attract to their magnet, calling this material non-magnetic. Magnets attract and repel each other.
Magnets have two kinds of poles.
Preparation involves placing a red sticker on one side of a ring magnet, and a blue on the other. Hold the second magnet close to the red side of the first magnet. Find the side that is attracted to the red and mark it blue because it is the opposite pole. Label all the ring magnets this way. Encourage students to experiment with their red and blue magnets to see what they find.
