FAQs
Final results, after being removed from the water.. As you can see, the gummy bear grew in all areas:length, width and depth. The gelatin kept the gummy bear from dissolving completely but the consistency did change from that of sponginess to a jellylike substance.
What is the conclusion of the gummy bear experiment? ›
In terms of volume and mass, they also changed depending on the concentration of salt water that the gummy was placed in. All of the gummies shrunk, but at different amounts. Through observation, it can be concluded that a higher concentration of salt water will affect the gummy more significantly.
What is the independent variable in the gummy bear experiment? ›

In this experiment, gummy bears were placed in salt water, sugar water, and tap water to find the measure of osmosis between the solution and gummy bear. Hypothesis: If the gummy bear is added to the solution, then it will lose its coloring and expand.
What does the gummy bear experiment show? ›
In this experiment, the gelatin in the gummy bear acts like a cell membrane in living cells. The gummy bears get bigger or smaller after soaking in the liquids because of a process called osmosis. Osmosis lets water pass in or out of a cell's membrane in an attempt to equalize the molecules inside and out.
What happens in the gummy bear experiment reaction? ›
In this reaction, the sugar from the gummy bear reacts with the oxygen produced from the decomposition of potassium chlorate. Purple sparks form, which are a result of the potassium ion (it has nothing to do with the colour of gummy bear you use).
Why does salt water make gummy bears shrink? ›
When the gummy bear sits in the water for a long time, some of the water flows into the gummy bear because of osmosis. This makes the gummy bear swell and get bigger. The gummy bear in the salt water doesn't get as big because the concentration is higher which means less water flows into the gummy bear through osmosis.
Which liquid will dissolve the gummy bear the fastest? ›
- If you want them to dissolve quickly, put them in water that has pepsin in it. That is sold as meat tenderizer. ...
- Once a gel has formed, it doesn't exactly dissolve easily, but just heating jello works. ...
- Pepsin breaks the collagen in the gummy bear down into amino acids, which are small enough to easily dissolve in water.
In this experiment, a demonstration of a spontaneous exothermic reaction will take place between a gummy bear and molten potassium chlorate. Once the potassium chlorate has been melted in a test tube, a gummy bear will be dropped to his doom and flames will burst out of the tube as a result.
Is the gummy bear experiment osmosis or diffusion? ›
The Science Bit
This is a process called osmosis. The gelatine structure of the gummy bear allows water molecules to squeeze in between its molecules and join them.
Osmosis causes some of the water molecules to move from the water in the jar into the gummy bear. As the gummy bear fills with water, it gets bigger. The gummy bear is made of gelatin, which acts like a sponge, so rather than dissolving in the water, the gummy bear grows in size.
What was your hypothesis as to what would happen to the gummy bear? ›
Answer & Explanation
The hypothesis might be that the gummy bear will expand in volume and mass after soaking in water. Based on the data in Table 6, the gummy bear absorbed water and increased in size. The volume and mass of the gummy bear increased from Time 1 to Time 2, indicating that it absorbed water and swelled.
Why do gummy bears shrink in vinegar? ›
The science behind the experiment:
The acid in the vinegar breaks down the protein, allowing more water into the bear, but also causes it to lose its shape, The salt water actually has less water than the gummy bear, so the water in the bear should move into the surrounding solution, causing the bear to shrink.
What were the results of the gummy bear experiment in vinegar? ›
The gummy bear we put in vinegar did expand, but lost all of its gummy bear shape and just became a blob. We believe that the acid in the vinegar dissolved the gummy bear completely. The answer to our gummy bear experiment was simple. Osmosis!
Why was the reaction with the gummy bear a chemical change? ›
In the video, when the gummy candy was placed into a test tube with the oxidizer, the gummy candy burned up and created new chemicals. Since new chemicals were formed, it is an example of a chemical change.
What is the science behind gummy bears after workout? ›
A handful of gummy bears, saccharine though they may be, are just what the doctor ordered in terms of a rapid glycogen fix. Glycogen replenishment causes a spike in insulin within the body, which opens up certain receptors on muscle cells.
