What is the gummy bear osmosis experiment?
The Gummy Bear has a selectively permeable coating which will allow water molecules to diffuse across, but inhibiting other larger molecules. In this osmosis experiment the water molecules move into the bear, thus enlarging it.
What is the hypothesis of the gummy bear experiment?
Hypothesis for Growing/Shrinking Gummy Bears When a gummy bear is placed in a hypotonic solution (e.g. water) then it will increase in mass and volume. On the other hand, its mass and volume decrease when placed in a hypertonic solution (e.g. salt water).
Why does a gummy bear expand in water?
Science behind Growing Gummy Bears in water, what happens? because there are more sugar molecules in the Gummy Bear than in the water. The Gummy Bear grows bigger!
What happens to gummy bears when placed in sugar water?
In water: The water will move into the gummy bear because there is a lot of solute (sugar) in the bear and there is no solute (sugar) in the water. So the water will move from the low sugar concentration in the water to the high sugar concentration in the gummy bear. That’s why the gummy bear shrunk!
How do Gummy Bears relate to osmosis?
When you put a gummy bear in water, it is a solute, and the water molecules are a solvent. Since the gummy bear does not contain water (remember, the water was removed when the gummy bear was made), water now moves into the bear by the process of osmosis.
What is the control group in gummy bear experiment?
The control group was the gummy bear soaked in regular water. Pure Water: Dependent Variable: If the gummy bear is put in pure water, then the water will stay on the outside of the gummy bear not affecting it.
What happens when you put a gummy bear in water for 24 hours?

How do you explain osmosis?
In biology, osmosis is the movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules, through a cell’s partially permeable membrane.
What is osmosis Class 9 short answer?
Osmosis is the movement of water molecules or a solvent from a region of low water concentration towards a region of high water concentration of solute through a semi-permeable membrane. Osmosis is a vital process in biological systems, which occurs in liquids, supercritical liquids and gases.
What is the hypothesis of a gummy bear?
Research Hypothesis: The gummy bear will dissolve in the water due to the fact that most gummy bears are made out of pure sugar. Also that since gummy bears are sugar and sugar usually dissolves in water. Also it will vary due to the amount of water that is used in the experiment.
Why do gummy bears absorb salt water?
The gummy bears in the salt water will shrink in size while the gummy bears in the tap water will grow, the ones in the salt water will shrink because of the salt in the water and the ones in the tap will grown because the ingredients in the gummy bears absorb water.
As soon as the gelatin candy or gummy bear comes in contact with water again, it will start to absorb some of it and this will eventually result to a bigger candy. With more water being absorbed by the gummy bear, it will also grow bigger.
What happens to a gummy bear in water?
The gummy bears in the salt water will shrink in size while the gummy bears in the tap water will grow, the ones in the salt water will shrink because of the salt in the water and the ones in the tap will grown because the ingredients in the gummy bears absorb water.
