The Gummy Experiment!

Problem: I'm trying to figure out which gummy bear would change the most when i put them into water, salt water and soda.

Hypothesis: My hypothesis was the soda bear will have the most change.

Conclusion: In conclusion my hypothesis was correct. Out of all the bears the soda one had the most change, the salt water bear had the least changes.

Procedures:

1. Take the bears from the liquid

2. Measure

3. Record measurement on paper

4. Take Pictures

5. Put pack in liquids

Abstract:

The Gummy Bear Experiment!

A few month ago I was just thinking about what to do for this science fair and then something popped into my mind, “ What would happen to the gummy bear when I put it in soda, water, and salt water?” I’ve seen this experiment before and I decided maybe I should try this out myself. I thought to myself out of the three liquids the most change would be the gummy bear in the soda.

How I set up my experiment was I measured out 1 ½ cup of liquid into each cup and labeled them so I would know which was which. Then I got a ruler and then measured the bears and recorded it on paper, I measured the length, width and how wide they were. Finally I got the three gummy bears and dropped them into the liquids. From that all I really had to do was take them out of the liquids every morning and measure them, also I would take pictures. I only did this experiment for three days and the bears changed a lot each morning.

It all started January 2 when i got all of the stuff that was needed for this experiment, on January 3 was when all of the fun really started. I started out by measuring the gummy bears and doing all the steps that I said before, the gummy bears were originally 2 cm long, 1 cm wide and 1/2 cm thick. Then I took pictures before dropping them into the liquid. On January 4, I took the gummy bears out of the water and measured them. The soda bear measured at 3 cm long, 1 ½ cm wide and 1 ½ cm thick. For the water bear it was 3 cm long 1 ½ cm wide and 1 cm thick. As for the water bear in the salt water it measured at 3 cm long 1 ½ cm wide and 1 cm thick. The salt water in the cup started turning a bit orange. Before putting them back in I took pictures. On January 5, i took the bears out again and measured them. The soda i could even measure because during the day before it split apart. The water bear was 4 cm long, 2 cm wide and 2 cm thick. For the salt water bear it was 3 cm long, 1cm wide and 1 ½ cm thick. Finally it was January 5th and it was time to check the ending result, soda I still could not measure because it fell apart, the water had a huge change and the head fell off so i couldn't really measure it, and for the salt water bear it was 3 ½ cm long, 1 ½ cm wide and 1 ½ cm thick.

After three days of measuring and taking pictures I found that my hypothesis was correct. In the end the soda bear couldn’t even be measured, it fell apart. If I wanted to make this experiment more accurate i would have to do it many more times. If I wanted to improve this experiment I would make sure i checked the bears the same time morning. Furthermore, with all the data i collected from day one to day three my experiment was half and half, half fair and half not fair.
