Osmosis in Potatoes
-
What is osmosis?
Is the diffusion of water across a semi-permeable membrane from an area of high concentration of water, to an area of low concentration.
Semi-permeable membrane: a layer that only certain things can go through. For example, parts of the potato that water can pass through.

Hypothesis
The water of the potato placed in saltwater moves out by osmosis, while the potato placed in tap water will absorb the water from outside. Because salty water has a lower concentration of water than tap water.
