Hovering Potato ~ Activity Plan, Admin Stem For Success
STEM for Success Showcase
This experiment is a great example of chemistry. This experiment relies heavily on density and diffusion.
-
Water is less dense than half of a potato. Therefore, the potato sinks.
-
Sugar water is more dense than half of a potato. Therefore, the potato floats.
By slowly adding water to sugar water, two layers are formed which allows the potato to hover in between. Slowly adding the water allows for diffusion to occur at a minimum.
