5 gummy bears b. 5 beakers c. A scale d. Distilled water e. Salt f. A cover for each beaker g. A paper to put on the scale h. Tweezers The independent variable is the salt in the water. "Osmotic pressure. The gummy bear left in salt water will shrink swell stay the same. Two blue gummy bears had a height of 2 centimeters each. New gummy bears soaked in salt water will shrink, but imperceptibly so. The purpose of this experiment was to study why the death occurred among those who drank salt water. So the water swells the gummy bear rather than dissolves it. When gummy bears are made, gelatin and water are heated and mixed (like when you make gelatin at home). Experiment- 1. You may need to learn what Osmosis and Osmotic pressure are for your test. Most sugary candy dissolves in water. The gelatin makes the Gummy Bear act more like a sponge by absorbing water instead of being dissolved in it. In vinegar, the gummy bear got bigger, but it also started to fall apart, and that’s because of the acid in vinegar which can dissolve gelatine. -scale!& ruler ★ Procedures: Materials needed: a. In fact, you might want to try this experiment first, so your kids understand that this is true. The gummy bear left in no water will shrink swell stay the same. 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. Because there are more solute molecules in salt water, and since Gummy Bears are made up of water, the water moves out of the gummy bear and it may shrink. The bears' gelatin construction will cause it to hold its shape and size, for the most part, even when water leaves the bear. Salted water had much higher concentration than the pure one, so less water went into the gummy bear (in gummy bears there is some water, but not much, so the concentration is very high). When salt is dissolved in water, the salt is the solute and the water is the solvent. This is because they’re made with gelatin. dissolved in 100 mL water -3 gummy bears! The salt from the water gets absorbed by the bear. Gummy bears and gummy anything is made out of gelatin, a protein byproduct extracted from bones . - After two nights: They had more bubbles in them but was still the same size. In the bowl with the salt water, we tried to balance the amount of stuff {salt} dissolved in the water with the amount of sugar dissolved in the gummy bear. After The mass of these gummy bears together were 5. Many types of liquids could dissolve gummy bears. The mass of these gummy bears together were 5. Gummy bears are an exception – they don’t dissolve in water. ★ Materials: -3 beakers -100 mL water -labels -salt! Gummy Bear Experiment: Salt Water II 28 grams. Gummy bears can expand with water because there is less concentration of water molecules surrounding the gummy bears therefore making it hypotonic. The dependent variable is whether the amount of water lost or gained in the gummy bears varies in a linear fashion. Effect Of Gummy Bears In Salt Water And In Regular Water My Conclusion was.. Bibliography In the salt water: - After one night: They were the same size but had a few little tiny bubbles in them. A solute is a substance dissolved in another material. Since our gummy bear placed in the salt water solution did expand a little bit, we knew our salt water solution did have a lot dissolved in it but not quite as much as the gummy bear did. Gelatin is water soluble, although temperature does affect the rate of solubility. Now, the water percentage has decreased, so it is not as large. Why does salt dissolve in water and gelatin doesn’t? Two orange gummy bears had a height of 2 centimeters each. 37 grams.
