Things that squish could include bubble wrap, fabric, cardboard, paper scraps, airbags, straws that break etc. Each group gets a bag of materials, 2 pencils, and 2 sheets of scrap paper. Brainstorm ways to increase the likelihood of safely landing their eggs. It takes energy to deform a material, so the more material you can put in front of the egg to absorb the kinetic energy through deforming the better chance you have of your egg surviving. Exploration: Challenge the students (in teams of 23) to build a structure in 40 minutes that will prevent an egg from breaking when dropped from a high place. What is one big way to absorb a lot of kinetic energy quickly? When it stops suddenly you need to absorb all of that kinetic energy (the energy of movement), ideally not into your beautiful pristine egg. Just before the egg hits the ground it is moving fairly quickly. You also want to think about how your egg will be buffered. If your egg drop experiment has protection on only one portion of the egg, you need to make sure there is a way to guarantee how the egg will descend to the ground as you are leaving yourself exposed. Drop it on its side or its top/bottom with no protection and it will break. A successful egg drop project means your egg has no cracks on it whatsoever when you take it out.
