Sinking/Floating - Gravity vs. Buoyant Force

Today looked like a kindergarten water table class as the the students explored buoyancy! Using balls, corks, and an eye dropper, the kids experienced what a buoyant force felt like. They tried to combat the force of gravity with the balls and corks, but always lost. They were challenged to see if they could get their eye dropper to float, or suspend, at various levels in their tank of water. They quickly discovered that by adding or subtracting water, they could get the eye dropper to suspend at certain levels. The connection was made that more water meant more mass.
