Scientists try to find out how long it takes worms to become flies. Does the time it takes them to become flies depend on their age or on the kind of worm? The scientists also conduct experiments with balloons and lasers. Part of the House of Science Series.
Cars use airbags. Packages use airbags. Why shouldn't eggs use airbags too? Students 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 students use the engineering design process, apply a variety of science concepts, and learn about NASA's exploration of the solar system. Part of the "Design Squad Nation" series.
Humans have always been intrigued by the idea of flight. Experiments with Hot Air Balloons led to a pig and duck being the first air travel passengers. From there, the Wright Brothers created the first airplane, and aviation was off to the races. From the jet engine and military aircraft to passenger planes, worldwide travel is now a matter of hours rather than days or weeks.
