Let’s talk about the word osmosis. What does it mean? Osmosis is a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane. In this process, water molecules move towards a more concentrated substance. This activity doesn’t just show the osmosis procedure, but it also allows for kids to make predictions and form a hypothesis of what will happen.
So before we get started, let’s get a pen and a piece of paper and predict what you think is going to happen to the gummy bear while it’s in water.
