Conduct and Experiment—Whelk-Come to Mathematics

This Conduct and Experiment—Whelk-Come to Mathematics lesson plan also includes:

How many drops does it take before they break? Class members conduct an experiment to simulate seagulls dropping mollusks to break them open. Using peanuts as a substitute shell, pupils drop from different heights and collect data on how many drops it takes to break open. They compare their results to their previous conjectures to finish the second lesson in a series of four.
