Science often begins with an “I wonder” and is followed by an experiment to discover. Our 4th grade teachers posed the question of how many licks does it take to get to the center of a tootsie roll pop to help the students review data collection and the scientific method. After making a hypothesis, students were excited to collect that data and paid careful attention to not lose track of their count. As a group students analyzed their results, compared them to their hypothesis, and communicated their findings.
This experiment piqued the students’ scientific curiosity and resulted in interesting observations. The class averaged 374.4 licks to get to the center. Students noticed warmth will cause candy to melt and the most effective way to the center was to lick the same spot. Students compared this to a river eroding rocks. What an amazing comparison!
