The Temperature Affect on Gold Fish Respiration Rate
Abstract:
In this lab activity, we had to determine whether the temperature would affect the gold fish respiration rate when we decrease the water by 2 degrees Celsius three different times. We did this experiment by placing a fish into a beaker and counting its breaths. We first put the fish in a beaker with room temperature water. We then added ice into the beaker until we dropped the temperature 2 degrees; we did this step 3 different times, therefore, dropping the temperature to a total of 6 degrees. Each time we did added ice and dropped it 2 more degrees, the respiration rate of the goldfish decreased. The results show that with the temperature decreasing, the gold fish respiration
The temperature begins at 20.3 degrees Celsius (room temperature), which shows a respiration rate of 87.8; the temperature gets lowered at the end to 10.9 degrees Celsius, which shows a respiration rate of 55.6. These results prove my hypothesis wrong; temperature does, in fact, have an affect on goldfish respiration rates.
Discussion/Conclusion:
Overall, we saw that our hypothesis was incorrect, and that the water temperature actually does have an affect on the respiration rate of the goldfish. Our results show that the respiration rate of the fish continues to slow down as we decreased the temperature to two degrees Celsius each time. This is because the colder the fish gets, the less energy it has. Not only does could the temperature have an affect on the goldfish, but there could be several other reasons as to why the respiration rate of the fish slowed down. The fish could have been sick, scared, and simply just not used to this new habitat. Also, it may not be the fish, it could always be human error. Someone could have easily miscounted the number of times the fish was breathing. Sometimes it looked like our fish was breathing but we were not for sure, so we could have easily miscounted those and added them when we were not supposed to. Overall, I enjoyed this experiment and I would like to do it
My hypothesis for this experiment is that the higher the levels of caffeine the water flea was exposed to, the quicker the heart rate would be.
I predict that when the egg is placed in the vinegar solution, the calcium carbonate shell will dissolve. I predict that when the egg is placed in a hypertonic solution such as corn syrup, it will crenate. I predict that when the egg is placed in a hypotonic solution such as water, it will expand.
In each temperature increment there were three different flasks filled with different levels of CO2 in the water to show the effects of ocean acidification on the larvae. The first flask was filled with present day CO2 levels of 380 parts per million (ppm), the second was filled with 710 ppm CO2, and the third was filled with 3,000 ppm CO2. The last two flasks are estimated of what the ocean CO2 levels will be in year 2100 and 2300, respectively. The results of each flask were assessed on days 3, 7, and 14 and were tested to find out the levels of calcium the larvae contained. However, not all larvae were tested because the researchers used random sampling to test the larvae to because this created separation from the few mothers of each larvae. To test the calcium content of the larvae the researchers used ion chromatography. Ion chromatography separates different ions to show the content of each ion in the larvae, so this shows the calcium levels because calcium ion can be separated to show the
Temperature can determine the chemical reactions in metabolism. When temperature is high, chemical reaction will increase which will have more metabolic activities. In contrast, when temperature is low, metabolic activity will decrease. Metabolic level has an high impact on activity levels. Thus, temperature will affect C. nemorails’ activity level. As temperature increases C. nemoralis’ activity level will increase and as temperature decreases C. nemoralis’ activity level will decrease. However, C. nemorails cannot adapt to temperature above or below its tolerance temperature 8-22C or else they remain at rest or their activity levels will be relatively low.
Imagine this, you’ve lost your focus, you start to get bored, you begin playing with your fingers, you don’t know what to do. Suddenly, you see a beautiful Goldfish swimming around in the water peacefully. It calms you down and gets you focused again. Or maybe in free time you and your friends don’t know what to do, well a Fantail Goldfish is colorful, bright, and keeps you entertained. Our school pet should be a Fantail Goldfish because they typically live about 10 years in an aquarium, so they don’t die quickly. Goldfish have no eyelids so they can’t close their eyes like we do when we're asleep. Despite that, goldfish do rest sometimes during the day and throughout most of the night. Also, make sure to feed your fish in small amounts. Do
Cold water is the key aspect in the phenomenon called the mammalian diving reflex. This reflex has been beneficially used for thousands of years by whales, dolphins, seals and other mammals that inhabit the frigid waters of the world. The diving reflex slows heart rate and causes peripheral vasoconstriction to keep blood and oxygen to the brain and other vital core organs. This reflex allows these mammals to conserve oxygen and stay submerged over longer periods of time, providing them more time for finding food, protection and travel.
The null hypothesis at the inception of this lab stated that the breathing rate of a gold fish would not be effected with decreased water temperature around it. The alternate and working hypothesis however stated that decreasing the water’s temperature will decrease the goldfish’s breaths per minute. After preforming the experiment, my results support my original hypothesis as the fish’s breaths per minute did drop when the water temperature lowered. In my group’s experiment, the fish’s breathing rate stayed constant after only decreasing the temperature by 5 ◦C, the breathing rate then plummeted once the water temperature was at 10 ◦C. As a total class, the experiment further supported the hypothesis with the breathing rate per minute dropping

This experiment tested whether or not baking soda affected the rate of photosynthesis over time. For this experiment there was a beaker containing 100ML of running distilled water added to a beaker with 1% or 1 gram of baking soda. Then another beaker was placed beside that beaker with 100ML of 0.2% sodium bicarbonate. This was done to test the rate of photosynthesis with different amounts of baking soda over time. Both beakers were placed under a red light with 25 watts of electricity for two trials at 23 degrees Celsius. After 10 minutes in the first trial, it showed 1% of baking soda caused a greater amount of leaves to float over time; while the 0.2% sodium bicarbonate caused a fewer amount of leaves to float to the top of the beaker overtime.
The incident happened long ago, but nobody ever seemed to remember. Except for Michael. After all these years, every piece of the pain was carved in his memory, as if he was always there, always making the mistake. He was eleven, an appropriate age to start to learn things.

In a 100ml beaker 30mls of water was placed the temperature of the water was recorded. 1 teaspoon of Ammonium Nitrate was added to the water and stirred until dissolved. The temperature was then recorded again. This was to see the difference between the initial temperature and the final temperature.
The purpose of this lab was to study the response of the genus Daphnia to chemical stimuli and to examine human responses to different stimuli. A stimulus is an incentive; it is the cause of a physical response. Stimuli can have a physical or chemical change; an example of a physical change is a change in temperature and sound. An example of chemical change would be changes in hormone levels and pH levels. Muscular activity or glandular secretions are responses that occurs when stimulus information effects the nervous and/or hormone system. Daphnia is a genus; it is a small crustacean that lives in fresh water. The body of the daphnia is visible and its internal organs are clearly seen thus it was chosen for this exercise. The
Oxygen has become essential over time but there is major difference in aquatic respiration versus land reparation in vertebrates. In osteichthyes (bony fish), the largest group of modern fish, counter current flow is required for the most efficient form of gas exchange and respiration when chondrichthyes (cartilaginous fish) use ram ventilation. Fish in general require a more efficient form of gas exchange then mammals because their medium, water, contains less than 1% dissolved oxygen compared to 2...
I'm swimming about and see eight other fish swim around me. The thermometer reads 72 degree Fahrenheit, but the cold water suits me just fine. There are white, black, and gray pebbles all over the bottom of the tank which collects the deserted food particles. I accidentally suck up a small pebble with the fish food I tried eating from the bottom of the tank.
