Investigative Lab Proposal - Assignment Example

Lab Effect of Temperature on Gold Fish Respiration Rate. The aim of the study is to determine how temperature canimpact the rate of respiration of Goldfish. Three goldfish will be used in the study. The temperatures to be considered in the study will range from 4 to 41 °C.IntroductionGoldfish is a freshwater fish, belonging to the family Cyprinidae and genus Carassius, It is commonly found in ponds and aquariums. It is native to China, and the first time to be domesticated was centuries ago from the wild type, carp like, olive-colored fish that is up 40 cm long.

Subtropical is their native climate and they dwell in freshwater that has a pH of 6.0–8.0, a 5.0–19.0 dGH water hardness and 4 to 41 °C temperature range Despite they they may not survive long enough at higher temperatures. Infact, they are taken to be not suited to living in a tropical fish tank that is heated, as they are employed to the greater oxygen amount in unheated tanks as well heat can burn them. (Copp and Sayer, 2010)ExperimentMaterials: Infrared gas analyzer, Fish tank with a heater, three gold fish, thermometer and two hot water bags.

For this experiment, Gold fish 1 will be placed directly into the fish Tank with temperature near to 40c . Gold fish 2 will be placed in fish tank with room temperature. Gold fish 3 will be placed in fish tank with a temperature near to 4o0c.The temperature recording will be done through placing the thermometer in the fish tank. The machine will be expected to match after every five minutes. Alteration will be done at different points. Hypothesis and Rationale: The experiment will be carried out to ascertain if temperature has a significant effect on respiration rates of the Gold fish.

It is based on the fact that there is kinetic energy alteration of enzymes involved in respiration with change in temperature thus its rate of reaction can either be faster or slower Null hypothesis: temperature has no significant effect on the Gold fish rate of respiration.Alternative hypothesis: There is significant impact of temperature on the Gold fish rate of respiration.Works CitedCopp GH, Sayer CD (2010) Norfolk Biodiversity Action Plan – Local species action plan for crucian carp ( Carassius carassius).
