What do you learn from the gummy bear experiment?
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 bear got bigger!
What is the independent variable in the gummy bear experiment?
Introduction
| Research Question | How do different solutions cause gummy bears to change in size? |
|---|---|
| Age: | 4th grade and up |
| Time to complete: | 2 hours or more |
| Safety concerns: | none |
| Independent variable: Type of solution Dependent variable: Volume of gummy bear | Controlled variables: Time soaked in solution Type of gummy bear |
What is the science behind gummy bears?
Gummy Bears are made of a protein substance called gelatin, which gives candy a jelly-like texture. When the Gummy Bears are placed in water, the water molecules move into the pores because there are fewer water molecules in the gelatin than in the water.
What happens in gummy bear experiment reaction?
A gummy bear is dropped into an ignition tube containing a small amount of molten potassium or sodium chlorate. The sugar present in the gummy bear undergoes rapid oxidation forming carbon dioxide and water, assuming complete combustion, a very exothermic process.
Why does the gummy bear experiment 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.
What is the purpose of the gummy bear osmosis lab?
Osmosis is the movement of water molecules from an area of higher concentration to lower concentration over a semi permeable surface. The gummy bear in this experiment will act as the semipermeable surface, allowing water molecules to flow in and out of the gummy bear.
Is the gummy bear experiment osmosis or diffusion?
Why a Gummy Bear? 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 happens in the Golden Rain experiment?
The golden rain experiment involves two soluble ionic compounds, potassium iodide (KI) and lead(II) nitrate (Pb(NO3)2). When mixed, as the lead from one solution and the iodide from the other combine to form lead(II) iodide (PbI2), which is insoluble at low temperature and has a bright golden-yellow color.
What type of chemical reaction is the gummy bear experiment?
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.
What is the hypothesis for 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.
What are the variables in the gummy bear experiment?
The dependent variable is whether the amount of water lost or gained in the gummy bears varies in a linear fashion. The constants are the type of gummy bear used in this experiment, the type of salt, the type of beaker, the type of scale, the cover, amount of water, and the amount of time the gummy bears have.
What is gummy bear science?
The Science behind the Experiment. Gummy bears are made up of water, sugar, and gelatin. Like a sponge, gummy bears will absorb water but the gelatin keeps the bears from dissolving in the water.
What is the independent variable for gummy bear?
Tweezers The independent variable is the salt in the water. The dependent variable is whether the amount of water lost or gained in the gummy bears varies in a linear fashion. The constants are the type of gummy bear used in this experiment, the type of salt, the type of beaker, the type of scale, the cover,…
