Goldfish's Respiration Rate
My hypothesis was supported by the experiment. The goldfish’s respiration rate slowed down as the temperature of the water was lowered. The independent variable of this experiment was the temperature of the water, and the dependent variable was the respiration of the goldfish. When the goldfish lowered its respiration rate it did not intake as much oxygen. Without as much oxygen, the goldfish used less energy. The goldfish used what energy it did have to keep alive. Although the results seemed pretty persistent along all of the groups, the results could have been effected by a few things. For example, the fish could have not remained calm enough to count the number of respiration. The sizes of the goldfish were different. The amount of water
Gummy Bear Lab

Isopod Lab Report
1285 Words | 6 PagesThe χ2 value was 0.012858, df was 3 and hence the P value was less than 0.001 which proves that this result is not a result of random probability and is in fact reliable. In Trial 3, twelve isopods (60%) made the choices of hiding behind the sucrose sponge. The χ2 value was 0.00350342, df was 3 and hence the P value was in between
Daphnia Lab
620 Words | 3 PagesThe following experiment determines the effects of 50 ml tobacco extract on the heart rate of a crustaceans Daphnia Magna. Daphnia represents a small group of aquatic crustaceans, also known as “water fleas”, with clear exoskeletons, which makes studying their heart rate effortlessly. The heart rate can be observed using a microscope and counted under varying conditions. (Pritchard, J. B.) In this case, changing the type and concentration of natural plant substances reveals the effects of the plant defense mechanisms on the specimen of Daphnia Magna.
Goldfish Metabolism Experiment
1468 Words | 6 PagesBefore getting the goldfish subjects, two beakers were filled with 200 ml fish water and weighed. Four goldfish were then collected gently from the fish tank and each two of them were transferred into one beaker. Each beaker along with fish and water was weighed again to determine the weight of each pair of goldfish. For the control group of each trial, the oxygen chamber was firstly filled with 200 ml fish water; after two goldfish along with 200 ml water were transferred into it, it was sealed in order to prevent oxygen exchange with the ambient environment.
Pillbug Lab Report Hypothesis
864 Words | 4 PagesDescription of Experiment: Hypothesis Actual Hypothesis: If the majority of the pillbugs are on one side of the choice chamber, regardless of the conditions (wet or dry) of that area, then the rest of the bugs will move to that area. Null Hypothesis: The majority of the pillbugs being on one side of the choice chamber does NOT affect where the rest reside to. Alternative Hypothesis: If the majority of the pillbugs are on one side of the choice chamber, then the minority will control/convince the majority to come over to that side.
Isopods Vs Pillbugs
1003 Words | 5 PagesIn this experiment, we are testing whether or not the Isopods' have more of a preference for an environment with syrup or with water. The alternative hypothesis we devised is that if the Isopods are placed in between a syrup and a water chamber, then they will go towards the syrup chamber. This is believed because we believe the Isopods may have an attraction to the sweet scent and taste of the syrup. My group and I observed 10 pillbugs behavior over the span of 5 minutes, recording the number of pill bugs found in each chamber every 30 seconds. We fail to reject the null hypothesis because the chi squared value is 3.6 which is less than 3.84 (critical value at .05).

What Of This Goldfish Analysis
792 Words | 4 PagesIn the story, “What, of This Goldfish, would You Wish?” is about a man, Sergei Goralick, and his magical goldfish that granted him three wishes. Based on Sergei’s own speech, thoughts, and actions, readers can infer that deep down he is depressed and lonely. Sergei kept himself distant from everyone and was not very fond of strangers knocking on his door. One day a boy, Yonatan, showed up at Sergei’s front steps and insisted on asking questions for a movie he was filming, but Sergei was not appealed. As Yonatan still tried to question he was intrigued by Sergei’s magical goldfish, Sergei became overprotective and killed the boy.

Soccer Ball Hypothesis
231 Words | 1 PagesThe hypothesis for this project was “If a soccer ball has less regulation air pressure, then the distance the ball travels when kicked will be less.” It was therefore rejected. The soccer ball with less air traveled farther than the soccer ball with more air. The average distance of the soccer ball with less air traveled 29 yards, and the soccer ball wind or that I was tired.with more air traveled at an average distance of 19 yards. could’ve been caused by the It Everything went according to plan except that the hypothesis was rejected.
Effect Of Light Intensity On The Rate Of Transpiration
1950 Words | 8 PagesResearch Question: How does the presence of light impact the rate of transpiration in plants? Aim: The aim of this experiment was to investigate how the presence of light affects the rate of transpiration in plants. Hypothesis: As light intensity increases, the rate of transpiration (water uptake) in a plant increases.
Ocean Acidification Essay
861 Words | 4 PagesEver since the industrial revolution commenced, around one third of the carbon dioxide released by human interference has been absorbed by the ocean, which is one of the reasons of the drastic change in climate as well. Without the ocean absorbing carbon dioxide, the carbon dioxide n the atmosphere would be drastically higher, with possibly increasing the levels of climate change. The point of the research is to see how will the pH affect the organisms in the marine ecosystem and does carbonation affect an organism’s mass and form. Many organisms that are part of the marine food chain are going to be affected by ocean acidification due the levels of acidity deteriorating the calcium carbonate within the animal. It turns out
