Carolina STEM Challenge®: Egg Drop Kit
Students learn about momentum, collisions, impulse, and stopping force as they address the engineering challenge, "How can a container be built to protect fragile cargo during a collision?" Teams start by building cubic, triangular, and cylindrical egg containers, dropping them from increasing heights while evaluating their effectiveness at protecting an egg from damage. Students apply what they have learned to achieve the highest drop in which the egg remains intact, competing in one of 4 design challenges: Single Drop, Three Sides Drop, Limited Mass Drop, or Limited Volume Drop. The activity concludes by entering all the reengineered egg protectors into a classroom competition.
