Gummy Bear Lab
Transcript of Gummy Bear Lab
If sugar is added to the water will it affect the amount of diffusion that occurs? If so, will it cause the amount of diffusion to increase or decrease? Hypothesis If sugar is added to the water then the amount of diffusion will increase. Question of
Investigation Materials -3 Beakers
-1 Graduated Cylinder
-3 Gummy Bears
-15 Grams of Sugar
-285 mL of Water Procedure 1- Gather materials.
2- Measure 5 grams of sugar and 10 grams of sugar and pour into separate beakers.
3- Measure the weight of each individual gummy bear using the scale and record its weight
4- Measure 100 mL, 95 mL, and 90 mL of water using graduated cylinder.
5- Pour 100 mL of water into an empty beaker, 95 mL of water into beaker with 5 grams of sugar and 90 mL of water into beaker with 10
grams of sugar.
6- Mix water and sugar together until sugar is
7- Place one gummy bear into each beaker.
8- Let gummy bears sit in the solution for
9- Remove gummy bears from solution and wipe of extra water.
10- Re-weigh each individual gummy bear and record new weight. Summary We placed a gummy bear into a beaker containing different concentrations of sugar and water and let them sit for thirty minutes. We took the weight of gummy bear before and after in order to calculate the weight gain and the amount of diffusion that occurred. These calculations helped us to prove our hypothesis and to answer our Question of Investigation. Data 5 Minutes 10 Minutes 15 Minutes 20 Minutes 30 Minutes 25 Minutes Conclusion In conclusion, the data we collected answered out question of investigation and proved our hypothesis to be correct. The amount of diffusion occurring increases with the amount of sugar mixed in the water. Our data proves this because the weight gain of the gummy bear that sat in 100 milliliter of water and 0 grams of sugar was less then the weight gain of the gummy bear both in the 95 milliliter of water and 90 milliliter of water. The difference in weight with the gummy bear in 100 milliliter of water and 0 grams of sugar was 0.472 grams. The weight gain of the gummy bear in 95 milliliters of water and 5 grams of sugar was 0.616 grams. Lastly, the weight gain of the gummy bear in 90 milliliters of water and 10 grams of sugar was most increased at 0.688 grams.
