Groups report out to form aggregate data. Compare results to predictions. Brainstorm how to record, compile and graph data to determine which type of magnet was able to attract the greatest number of paper clips. Elicit inferences based on data. Ask participants to explore moving the magnetic objects along the tabletop without touching.
Participants explore by placing magnet a distance from the objects and under the tabletop.
Participants draw inferences from data through brainstorming. Use groups as above to explore how magnets interact with each other. Distribute two bar magnets only to each group. Ask participants to predict what will happen when the two magnets are placed near each other. Direct participants to place magnets near each other using three different orientations and to record observations.
