Gummy Bear Lab
Hypothesis:
*What do you think will happen to a gummy bear if you leave it in water overnight?
I think that the gummy bear's size will expand, because it is absorbing the water in the container.
Measurements
Bear color length width thickness volume mass density 1- Peach 2.2cm 1.3cm 1.1cm 3.15cm3 2.3cm3 .76cm3
2- Clear 3.2cm .2cm .2cm 12.8cm3 8.9cm3 .69cm3
Amount of change 1cm 7cm 9cm 9.65cm3 6.6cm3 .07cm3
3- 3.5cm 2cm 2.3cm 16.1cm3 7.5cm3 .47cm3
Throughout day one the water was at 50 and the second day was 40. The third day stayed the same as day 2.
Questions
1. Was your hypothesis correct?
Yes, because my gummy bear did expand in size.
2. What change is greater - volume or mass?
Volume, because the measurements changed.
3. Was there a change in density?
Yes, the bear absorbed a lot of water. Therefore the bear got heavier.
4. How do your results compare to those of your classmates?
My bear came out with a heavier mass and we all started with different sized gummy bears.
5. State the results of the day 2-3 salt water test.
length- 2.2cm width- 1.3cm thickness- 1cm volume- 2.86cm3
density-.87
6. Look specifically at the volume. Explain changes based on your measurements.
The changes would be that the volume is lower than the gummy bear in regular water, and not salt water.
7. How would you change the lab to test another variable?
I would have tried to leave it inside of alcohol, soda, and juice. Just to see what would have happened. I would have also put the gummy bear into a different temperature water (hot water).
8. The biological process used during this lab would be osmosis. Osmosis is being occurred because in osmosis a less concentrated solution is turned into a more concentrated one. The gummy bear lab is using osmosis because the gummy bear was in a much simpler form and a small size. After leaving the gummy bear into the water over night the bear turns into a bigger gummy bear. Osmosis is used especially in the size of the gummy bear. Not only size but the mass and the length. The gummy grew into a way bigger and heavier bear, than when it came from its original package.
