Planavsky 1 Abstract: In this paper I discuss my research and data for the relationship between the length and weight of aquatic organisms, the relationship between temperature and respirations of a goldfish, and how I used deductive reasoning and the scientific method to decipher the contents of an unknown box. I included, my diagrams, data tables, and list of the steps of the scientific method to make my research easier to understand and faster to access. Introduction: The scientific method is the basis of all scientific discoveries and studies. This experiment shows the many uses of the Scientific Method. The first and most important part of any scientific research is the observations. “A good scientist is observant and notices thing in the world around him/herself.” (Carter) After the observations have been taken you must form a hypothesis. After forming a hypothesis it must be tested. “ An experiment is a tool that you design to find out if your  ideas about your topic are right or wrong.” (Understanding) If the experiments prove your hypothesis false  you must reformulate or modify your current hypothesis.  If after multiple experiments are completed and the results are consistent, then a hypothesis can become a theory. (Wudka) Objectives: To show the ratio of length to weight in different aquatic species. To show the relationship between fish respirations and the water temperature. To explain how the use of the scientific method helped to develop and decipher what was in a closed box. Materials and Methods: Aquatic Organism Measurements Materials: Two species with 5 specimens of each, Asterias (common name Starfish) and Arbacia (common name Sea Urchin) with the spines removed. Use of a ruler with millimeter increments, a top loading balance measuring in grams, a petri dish for weighing the samples on the top loading balance, a calculator for determining the mean, variance, and standard deviation of the data gathered from your samples. Method: Starting with one specimen of Asterias, I measured the length as shown in Figure-1A with the millimeter ruler. Then I took the sample over to the top loading balance along with a petri dish. Placed just the petri dish on the balance, nullified the weight of the petri dish by using the tare ability that the balance has. Then I placed the specimen onto the petri dish that was
