The Effect of Water Temperature on the Breathing Rate of Goldfish
The scientific method of problem solving is a method that scientist use to predict and provide evidence to back up a certain experiment. The scientific method of problem solving consists of a series of steps that must be completed. The first step is to recognize the problem, observe the thing the experiment will be conducted on, and gather data. The second step is to form a hypothesis,which is a educated guess, which is formed after the gathering of data from the observation. The third step is to test your hypothesis by experimenting and recording data to determine if the hypothesis solves the problem or not. The fourth step is to analyze data and draw a conclusion, yes, the hypothesis was correct, or no, the hypothesis was incorrect. A hypothesis is an educated guess or what you think will happen. When forming a hypothesis two hypotheses are made which are null hypothesis and a working hypothesis. The null hypothesis is a hypothesis that states that nothing will happen, no matter what happens to the independent variable, the dependent variable will not change. The working hypothesis is a hypothesis that states that the independent variable will affect the dependent variable. The data in a experiment supports the working hypothesis and falsifies the null hypothesis by proving that the independent variable will affect the dependent variable.
An endotherm is a living organism that has built in mechanisms that maintain a constant body temperature. An ectotherm is a living organism who’s body temperature fluctuates with the surrounding or ambient temperature. Fish are ectothermic which means that when the water temperature decreases, the body temperature of the fish decreases. When the body temperature of the fish decrease, the breathing rate decreases. The metabolic rate in a fish is usually estimated by oxygen consumption, so when the breathing rate decreases the metabolism...
