Students write a hypothesis about the strength of two magnets. Then, students design an experiment to test their hypothesis, using the number of paper clips that the magnet will pick up as the testable variable. Students perform their experiment, record and interpret their data, and state a conclusion about which magnet is stronger. Students observe the characteristics of six leaves. Based on these characteristics, students develop categories and classify the leaves into these categories.
Students drop a rubber ball from two different heights, counting the number of bounces in each case.
Students predict the number of bounces that the ball will make from three other heights and then test their predictions.
