In conclusion, the data from the goldfish respiration lab supports my hypothesis. My hypothesis was that if I were to put the goldfish in the 27OC water then the goldfish will breathe faster because the water is hotter and the molecules move further apart. Therefore, the fish will have to take more breaths. In 10OC water, the goldfish will take fewer breaths because in colder water the molecules move slower and they are closer together. As a result, it will have to take fewer breaths. My lab partner and I put a goldfish in three different temperatures of water. The first thing we did was put the goldfish into the room temperature beaker of 23OC water and recorded the number of breaths per minute three separate times. The outcome of numbers were 108, 86, and 55. The average of BPM in 23OC water calculated out to be 49. Next we put the goldfish in the 27OC water and recorded the breaths per minute again. The new outcome of numbers was 161, 163, and 129. The average breath per minute of the goldfish in 27OC water was 151. We finally recorded the goldfish’s BPM in the 10OC beaker of water. Our results were 46, 55, and 49 which gave us an average of 50 BPM. This data proves that the goldfish took more breaths in warmer water than it did in colder water because the oxygen molecules are arranged further apart in warmer temperatures. In order for the goldfish to get the oxygen it needed, the goldfish had to maintain a stable level of internal conditions even though the water temperature was changing. This is called homeostasis. Homeostasis is when the body tries to keep the oxygen level stable. The change the goldfish had to go through is called acclimate which is an organisms change in response to a change in the organisms environment. By doing this lab, I learned what homeostasis is and I learned what the difference is between acclimating and
