Jackson finished his symmetrical butterfly design. Then I gave Jackson an uncooked uncracked egg that he had to name. He named his egg 67. His design challenge was to create an egg crate that will protect his egg from cracking once it is nestled securely inside its crate and dropped from various heights on the playground. He made a very secure crate out of toilet paper rolls, foil insulation for food, tape, and cardboard. He also added wings like a hang glider. We measured height distances on the playground. We have 6 feet, 8 feet, and 10 feet drop options.
