Science meets Real Life Cheryl Hankins SC300: Big Ideas in Science: From Methods to Mutation There are two different ways to use the scientific method. The five step method involves observing/research‚ hypothesis‚ prediction‚ experiment‚ and conclusion (Understanding and Using the Scientific Method‚ 2011). The seven step method involves observation‚ question‚ research‚ guess‚ experiment‚ analyze data‚ and conclusion (Trefil & Hazen‚ 2010). Whether using the five step method or the seven step

enzyme. The hypothesis was that alkaline phosphatase activity will be critically affected by pH effects. The hypothesis was valid because the data shows that the pH values for the acidic‚ basic‚ and neutral tubes increased over time‚ absorbing at similar rates. The basic tube had the highest rate of absorbance while the acid tube had the lowest rate of absorbance. In the following experiment‚ the effects of varying enzyme concentrations on the catalytic rate of ALP were tested. The hypothesis was that

steps used to basically form an opinion and test that opinion. The method steps include‚ observation‚ research‚ creating an educated guess‚ or hypothesis‚ testing that hypothesis‚ analyzing the test results‚ and recording the results as true or untrue. If testing of the hypothesis results in disproving it‚ the steps will begin again with a new hypothesis (Science Buddies‚ 2002-2012). One can easily follow the steps of the Scientific Method with a study of how plants respond to light. To

and 20 percent went to dry. Though we were wrong for the fourth trial. Only 40 percent of the isopods went towards the glucose and 60 percent went towards the water. This shows that the isopods prefer a moist area than a sweet one. Therefore‚ our hypothesis was incorrect. Discussion For future references what we could do to improve out methods of conducting this experiment is after each trial we should clean the choice tube to make sure there is no residue‚ which can cause miscalculations.

observations. The next step in the scientific method is experimentation. These are controlled tests that are used to confirm or discredit the hypotheses or laws. Once the experiments are completed we revise the hypothesis‚ or revise the law to form a confirmed hypothesis. Then we use the confirmed hypothesis to form theories. The theories are then also tested by experimentation in order to confirm or allow us to revise those theories. The last step is to report the results for others to use to increase their

Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water. What would your experimental approach be to test this hypothesis? What would be the independent and dependent variables? What would be your control?
