Getting to know my grow beast
I was given two different grow beasts, the first was a pink t-rex (Rexy) and the second was a blue brontosaurus (Bronto). Rexy was the first of the two beasts to be submerged. She swam in a bowl of room temperature water. As a class, we decided to measure our beasts by their length from the tip of their head to the tip of their tail.

Rexy Swims in Water!
Rexy's beginning length was 4.1 cm from head to tail. Rexy swam for about 3 days, for a total of 70.5 hours, respectively. At the end of her swim, I removed her from the water and her final measurement was 11.1 cm. Her growth rate was rather steady and started to slow down towards the end.

INVESTIGATION TIME!!!
To investigate the conditions that effect the growth rate of the grow beasts, I decided to change the liquid in which Bronto would swim in for about the same amount of time Rexy was able to swim. Bronto was submerged into 100% lemon juice (from concentrate). I chose lemon juice because of it's acidity. I was wondering if the acidity would penetrate Bronto faster, causing a faster growth at the beginning.

Bronto's Swim in Lemon Juice
Bronto's beginning length was 4.4 cm, however, Bronto did not enjoy the lemon juice. Not only did he not really grow that much but he also started to disintegrate the longer he spent time in the lemon juice (probably due to the acidity). I guess my hypothesis was correct in the sense that the majority of the growth happened towards the beginning of his time in the lemon juice, but he did not grow nearly as much as Roxy who was submerged in water. I'm guessing Bronto's growth was due to the fact there is still water in lemon juice from concentrate.



Overall, Bronto sat in the lemon juice for 4 days, approximately 78 hours. See below for growth details.
 * Hours || Length (in cm) ||
 * 0 || 4.4 cm ||
 * 4 || 4.5 cm ||
 * 8.25 || 4.6 cm ||
 * 21.25 || 4.9 cm ||
 * 24.5 || 4.9 cm ||
 * 28.5 || 5.0 cm ||
 * 33 || 5.0 cm ||
 * 44 || 5.1 cm ||
 * 49.25 || 5.1 cm ||
 * 52.75 || 5.1 cm ||
 * 57.75 || 5.2 cm ||
 * 70 || 5.3 cm ||
 * 74.25 || 5.3 cm ||
 * 78 || 5.3 cm ||

Conclusion
After completing this experiment, it is easy to say that pure room temperature water is a better solution to grow your beasts in. The acidity of the lemon juice did make the beast grow towards the beginning but it did not grow like the beast in water. Along with stunting the growth of the second beast, it also started to disintegrate. I am drawing the conclusion that since the lemon juice had some water in it, that is why the beast grew as much as it did. I drew this conclusion from the pervious data that water made the first beast grow. If I were to complete this experiment again I would try different solutions of water such as sugar water or salt water.
