What happens to different pairs of gummy bears left in different types of liquids?

Question:

Hypothesis:

I predict that the different liquids will change its form of the gummy bear because all the liquids have different type of chemicals. For example, Water + Gummy Bear = bigger gummy bear.

Procedure:

1. Gather my liquids (vinegar, salt water, water, etc.)

2. Then get a bag a gummy bears

3. Fill separate small bowls half way, with all the different types of liquids

4. Measure the volume and the weight of each gummy bear before placing into the bowls by using a ruler and a weight.

5. Place the two gummy bears in a bowl then let it stay there for 24 hrs.

6. When 24 hrs passes I will measure the volume and weight again to see the difference

7. Repeat steps 3-6 twice with a different pair of gummy bears

What Happens to Different Pairs of Gummy Bears that are Left in Different Liquids?

I wanted to investigate what would happen to a gummy bear that is left in different liquids. I decided to investigate in this sort of idea because I thought it was interesting and fun. I predicted that, the different liquids will change the form of the gummy bear because all the liquids have different chemicals. For example, water plus gummy bear equals a larger gummy bear.

I began testing after a collected all my materials. My first experiment session began after I filled small bowls with all the different liquids that I used. Before placing the gummy bears into the bowls I measured the volume and weight of each. After that, I put a pair in each bowl and let them sit there for at least 24 hours. As time went, I would go and check on the gummy bears to see if there was any difference. When all 24 hours passed, I remeasured each gummy bear to see if there was any difference.

The data that I collected and observed shows that most of the gummy bears grew in the different liquids. The average volume of each gummy bear was 3 cm3 and the average mass was 4.61 grams. Most of the gummy bears grew about 3.89 grams. All summarized, my data shows that there is a better chance on the gummy bear to grow than to shrink.

This project approved my hypothesis. My hypothesis was correct because I said that the liquids would change the gummy bears form. For example, the gummy bear that was in the water did grow, which means that the gummy bear is more likely to suck in the liquid to enlarge it. My experiment was accurate because each bowl had the same amount of liquid, each gummy had the same weight and volume, and each gummy bear was left in the liquid for 24 hours. Another thing that was accurate about my project was that the same supplies were used and the same brand of gummy bears was used. If I could improve this experiment, I would probably let the gummy bears stay in the liquid for a longer time or I could put more liquid into the bowls and measure how much liquid the gummy bear sucked. So in all, there was no differences in each bowl. I learned that gummy bears suck in the liquid to make them bigger, for example they are sort of like sponges. I also learned that gummy bears seem to go by a lot, and that waiting is time consuming and really fun.

Conclusion

My hypothesis was approved by my data, because I predicted that the liquids would change the gummy bears form. All my observations and my data proved this, because most of the gummy bears grew bigger than its original size. My experiment was accurate because the same brand of gummy bear was used. Other things that made this experiment accurate was that the same amount of liquid was poured in each bowl and each gummy bear was left in the bowl for the same amount of time. If I could improve this experiment, I could’ve left the gummy bears in the liquid for a longer time or I could have tried to use more liquids. In all my experiment was accurate and successful.
