Teams of grade 8-12 students are challenged to design and build simple devices which will float in water in normal gravity and will be expelled as far as possible from the water because of wetting characteristics when they experience apparent weightlessness, i.e., microgravity, in NASA’s 2.2 Second Drop Tower (shown below). To be clear, the … Read the rest ⇢
Teams of grade 8-12 students are challenged to design and build paddle wheels that will turn in water because of the wetting properties of their surfaces when they experience apparent weightlessness, i.e., microgravity, in NASA’s 2.2 Second Drop Tower (shown below). To be clear, the rotation of the paddle wheels must result from the hydrophilic … Read the rest ⇢
