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 »

Students are introduced to the important concept of density. They devise methods to determine the densities of solid objects, including the method of water displacement to determine volumes of irregularly-shaped objects. By comparing densities of various solids to the density of water, students discover that ordinarily, objects with densities greater than water will sink, while those with densities less than water will float.

Students investigate how the density of water changes the buoyancy of water. Students create a hypothesis about what will happen when placing the egg into the water.Students can research online different bodies of water (The Red Sea, The Atlantic Ocean, The Dead Sea, etc.) to find out about there salinity, density, and buoyancy.

Students explore the relationship between between density and buoyancy. After watching a video explaining buoyancy, students discuss displacement and floating. Students have a raft building competition. Afterwards, they conduct experiments to determine how a hot-air balloon floats. They write a paragraph summary explaining their findings. Full Review »
