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...

Students study Archimedes' Principle, flotation and the reaction of buoyant forces and explain the relationship between density and flotation.

Pupils examine how salt water is more dense than fresh water. They discuss how manatees need to float and sink, conduct a sink or float experiment, and conduct an experiment with eggs and salt and fresh water.
