Sink or Float
In this activity, students will investigate the densities of different fluids by observing whether hard-boiled
eggs sink or float in two different fluids.
Real World Science Topics:
- An exploration of the densities of different liquids
- An exploration of how objects float or sink in liquids of different densities
Students will gain an understanding of the densities of salt water and freshwater. They will also
observe how density affects whether objects will sink or float in a liquid.
