In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height. Learners must follow a certain number of design constraints (i.e. parachute's max length can only be 3.28 ft or 1 m). During the test, learners measure the time from the release to the impact, the vertical distance of the fall, and the speed of the egg when it hits the ground. This lesson guide includes background information about Solid Rocket Boosters (SRBs) and questions for learners. This is also a low-cost activity as the lesson guide recommends learners provide the materials.
