Sci-Friday: Defying Gravity At-Home Science Experiment


It’s Sci-Friday! Try Defying Gravity with this easy at-home experiment by Nancy B’s Science Club.

Is it easier to float in an ocean or a lake? Why is there a difference? The force of gravity pulls your body to Earth. But water exerts an upward force, called buoyancy (BOY-uhn-see) on your body. This buoyancy works against the force of gravity. Ocean water has something special in it — salt! Does salt water have a greater buoyant force than fresh water? Get more on this experiment, here
