The fourth grade students recently concluded a unit of study exploring the wonders of space and space technology. Based on the concept of robotic rovers landing on extraterrestrial planets, the students were tasked with an engineering challenge in which they designed and created devices to safely land an uncooked egg on a hard surface. The egg represented a robot rover sent on a mission to explore Saturn's moon, Titan. Various recycled materials were available, and a budget was implemented. Most groups were able to complete their craft in a sustainable manner and under budget. The devices were launched from the balcony by Mater's window. Several devices were 100% effective and the delicate robo-egg landed safely. Mission accomplished! See photos from the experiments in the gallery.
