= Gummy Bear Experiment =

= = =**In this experiment we will put 3 gummy bears, all the same color, in three different types of water. Distilled, Tap, and Salt. We will record how the gummy bear has in width, length and height in 24 hours then 48. Next we will find the volume by multiplying length times width times height.**= = = =**__Question:__**= =**What will happen when we put a Gummy Bear in tap, distilled, and salt water?**= = = =**__Hypothesis:__**= =**__Gretchen's:__ I think they will expand most in the distilled water because of the chemicals.**= = = =**__Zach's:__ I think that they all will all expand and get bigger.

What happened in my investigation was that the distilled water made the gummy bear grow the fastest and largest, the salt water made the bear grow the second biggest, the tap water grew the least. =

= 2. In the starting measurement the gummy bears were 400 (distilled), 420 (tap), and 2,295 (salt) mm in volume (It's not that salt's was huge it was tap and distilled were very small). On the second day the distilled was 9,000 mm volume, the tap was 1,530 mm and salt 4,522. In the last day of the experiment the distilled was 23,400 the tap was 1,190 mm and salt was 17,000. =

= 3. (Distilled) My hypothesis was that the gummy bears would expand the most in the distilled water because of the chemicals- This was supported because the distilled water did grow the largest, however the distilled water does not have any chemicals. (Tap water) The hypothesis for the tap water is that all the gummy bears will expand and get bigger. The distilled water will dissolve the most, then the tap water and last the salt water. This was supported because all of the gummy bears did get bigger. But the gummy bears didn't dissolve at the end of our experiment. (salt water) The salt water’s hypothesis was that the salt water gummy bear would expand in all directions and lose some of it’s colors.-This supported because the salt water gummy bear did grow in all directions, and the gummy bear’s color did go away a little =

= 4. The answer to our question is that the gummy bear in tap water will grow around 1,190 mm in volume, the gummy bear in the salt water will grow about 17,000 mm in volume. Also the distilled water was humongous recording at 23,400 mm in volume. =

= 5. There are more molecules in salt and tap, and the distilled has hardly any. So the water that doesn't have much molecules goes to the gummy bear because the gummy bear has the most molecules. =

= 6. Another experiment we would like to try is gummy bears in milk, lemonade and vinegar for 72 hours. =
