Students use materials found at a resource table to design simple devices that will house instruments to take water samples from a tub of water. They design 3 instruments, each varying in density so that one will float, one will hover and one will sink. The work in teams and each member contributes to the design. After experimentation, they share designs with the rest of class. Full Review »
