Cars use airbags. Packages use airbags. Why shouldn't eggs use airbags, too? Kids model NASA's airbag landing system in this activity from Design Squad Nation. They design and build protective covers made of balloons to protect an egg dropped from a height of three feet. Their systems model the airbag landing systems used by three NASA Mars missions. The kids use the engineering design process, apply a variety of science concepts, and learn about NASA's exploration of the solar system. This resource is useful for introducing components of Engineering Design (ETS) from the Next Generation Science Standards (NGSS) to students in Grades 3-8.
