Growing Gummy Bears. The experiment should include an independent variable (something like the amount or ratio of acid and base forms); a dependent variable (something related to the absorption in the lungs); controlled variables (all other conditions: type of heating element, dispenser, length of puff, etc.)
What are the results of the gummy bear experiment?
Expected results for gummy bear experiment. The distilled water is 100% water, so it clearly has more water than the gummy bear, which contains sugar. Water moved into the gummy bear, which caused it to increase in volume in this hypotonic solution.
How to make a gummy bear osmosis experiment?
INSTRUCTIONS ON GUMMY BEAR OSMOSIS EXPERIMENT: Take 4 gummy bears (one for every type of solvent, +1 for comparison) Gummy bears are excellent for this experiment because they are made out of sugar, water and gelatine. Gelatine doesn’t... Prepare your mixtures: put pure water in one glass, water ...
What type of change will occur to the gummy bears?
The change that will occur to the gummy bears is osmosis and the process that it uses is called equilibrium . This process of equilibrium allows water to diffuse from a higher area of concentration to a lower area of concentration. For a visual explanation, you can watch this science experiment video, or use this Gummy Bear Chemistry PowerPoint.
What happens to a gummy bear in hypotonic solution?
Gummy Bear Science Project Instructions 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).
What is the independent variable in the gummy bear lab?
The independent variable would be the types of water used in the experiment. Plain regular water, salt water.
What is a hypothesis for a gummy bear?
HYPOTHESIS. The mass and volume of a gummy bear that is placed in a salt solution will decrease due to the effect of osmosis. When placed in water, a hypotonic solution, the gummy bear will expand in size and volume due to the water entering it.
What is the purpose of the gummy bear 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 types of chemical reactions took place in the gummy bear experiment?
This process actually takes place in two steps: 1) the formation of potassium perchlorate, followed by 2) the decomposition of the potassium perchlorate. The sugar present in the gummy bear undergoes rapid oxidation forming carbon dioxide and water, assuming complete combustion, a very exothermic process.
Why does a gummy bear get bigger 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 liquid makes gummy bears expand the most?

What happens when you put gummy bears in different liquids?
A gummy bear will grow when placed in a variety of liquids by using the process known as osmosis. Since the gummy bear water was removed when it was created, when a gummy bear is placed in water the water will move into the bear by osmosis.
Why does gummy bear shrink in salt water?
If a cell is surrounded by pure water, water migrates into the cell and it swells. If a cell is surrounded by, for example, salt water or sugar water, water migrates out of the cell and it shrinks.
What will make a gummy bear dissolve?
The main solvent or liquid that you can use to dissolve gummy bear is hot water. Gummy bears are products of gelatin which is a substance that you can derive from boiling animal bones and skin. Gelatin is water-soluble implying that it will melt and make a solution when you deep it inside hot water.
How does sugar and water react with gummy bears?
Inside the gummy bear (trapped inside those pockets in the gelatin), you have water + sugar. There's more stuff inside the bear, so the water moves into the bear to try and make the proportion of sugar molecules to water the same in both places. (You can think about this like a sugar cube dissolving in a cup of water.
What is the chemical equation of a gummy bear?
(For those unfamiliar with written chemical equations, the abbreviations (s) and (g) are used for solid and gas, respectively.) Gummy bears are made of the sugar sucrose, C12H22O11, which is in turn is made of glucose and fructose, both C6H12O6.
What happens when you heat a gummy bear?
The gummy bear releases all the energy it has along with carbon, water, and carbon dioxide. This reaction is exothermic, meaning it releases large amounts of energy. The gummy bear bursts into flames and gives off a bright light, smoke, and a whistling sound.
What happens to a gummy bear in rubbing alcohol?
The acid made the gummy bear to get small and it destroyed the gummy bear's figure change. The Vinegar made the gummy bear to grow and the rubbing alcohol made the gummy bear get smaller.
How does gummy bear osmosis work?
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.
How to measure volume of gummy bear?
First, take the initial volume of each gummy bear. Measure the height, width and length in centimeters and then multiply the three numbers together to get volume in cubic centimeters. Record this in your data table for each gummy bear you'll be using. 2.
How long does it take for gummy bears to change size?
If your gummy bears don't change size, make sure they are fresh. Old gummy bears might take longer to change size. You can also increase the time of your experiment. Instead of one hour, put them back in the solutions and wait another hour. Discussion Questions.
How to make gummy bears with salt?
3. Fill your hypertonic and hypotonic cups with one half cup water. In the hypertonic cup, add the two tablespoons of salt and mix it by swirling the cup. 4. Next, add your gummy bears to the cups and wait at least one hour. 5. After the hour is up, fish out your gummy bears and place them on a paper towel.
What degree did Amanda have in gummy bears?
They have a Master's Degree in Cellular and Molecular Physiology from Tufts Medical School and a Master's of Teaching from Simmons College.
Does gummy bear water have sugar?
You should have calculated a negative percent change if your bear shrank as expected. Expected results for gum my bear experiment. The distilled water is 100% water, so it clearly has more water than the gummy bear, which contains sugar.
Does gummy bear have more water than distilled water?
The distilled water is 100% water, so it clearly has more water than the gummy bear, which contains sugar. Water moved into the gummy bear, which caused it to increase in volume in this hypotonic solution. You should have calculated a positive percent change in volume here, since the bear got bigger.
What is a gummy bear experiment?
Gummy Bear Experiment. The gummy bear experiment is a fun activity that teaches the basic concept of osmosis to the little ones in an easy manner. They will also be thrilled at the idea that their favorite gummy bears could teach them a lesson or two in science. Gummy Bear Experiment.
How to measure gummy bears?
Procedure. Measure the dimensions (leng th, breadth and height) of the bear with a scale. Measure its mass with the balance. Fill the bowl with water. Completely immerse the gummy bear in the water. Let the bowl sit overnight in a place away from direct sunlight. Next day, lift the bear from the water with a plastic fork, sieve or screen.
Why do bears grow?
Due to the process of osmosis, i.e., the movement of water molecules through a selectively permeable membrane from an area of high concentration to that of a lower concentration, the bear starts to grow. However, it doesn’t get dissolved as the gelatin is insoluble in water.
Do gummy bears grow in water?
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).
WHAT IS OSMOSIS?
Osmosis is the process in which solvent (most often water) moves from the area of lower solute concentration into an area of a higher solute concentration through a semipermeable membrane.
WHY DOES THE SOLVENT MOVES FROM LOWER TO HIGHER SOLUTE CONCENTRATION?
Think of the membrane as a wall with gaps (it’s semipermeable!). When solutions on both sides of the wall have the same concentration of solute, nothing interesting happens – there is the equal probability water molecules will move from each side of the wall so in the end concentration will stay the same.
WHY IS OSMOSIS IMPORTANT?
Osmosis is essential for the survival of all living organisms. It allows nutrients and minerals to move inside the cells and also for waste to move out of the cells. For example, plants absorb water from the earth through this process.
INSTRUCTIONS ON GUMMY BEAR OSMOSIS EXPERIMENT
Check the video at the beginning of the article to see how to conduct this experiment. We used three types of solvent (water, salt water and vinegar) but you can experiment with any type of solvent.
Science Behind the Gummy Bear Osmosis Lab
This science experiment lab is supporting the concepts of osmosis, equilibrium, solutions, solutes, and solvents. A solution is a homogenous mixture of one or more substances. The parts that are mixed to achieve a solution are called the solute and the solvents.
Instructions for Gummy Bear Osmosis Lab
Label each glass for a different kind of liquid (tap water, salt water, sugar water, milk, vinegar, etc.)
Why Did the Bears Get so Big?
Well, we already know from the introduction that water diffuses from an area of high concentration of water molecules to an area of low water concentration. At the beginning of the experiment, there is less water and more gelatin inside each gummy bear. As time goes on, this changes and the gummy bear begins to act as a sponge.
