Question

Science can be defined as a systematic approach to acquiring knowledge. Science is based upon facts and evidence rather than beliefs or superstitions. To understand Biology and science, you must first examine how scientific knowledge is obtained. Science is a process that involves several steps. Read the description of the steps involved in the scientific method in the text paying close attention to the steps outlined in Section 1.3. Then pick one of the examples below and describe the steps of the scientific method you would use to test the question or find the solution to the problem. In other words, please design a virtual experiment (using the steps of the scientific method) to test the hypothesis you make about one of the questions listed below.

Be sure to identify the steps (observation, hypothesis, prediction, experiment/test, controls, results, conclusions). In your responses to each other, help each other identify the parts of the process properly so that the results can be clearly interpreted.???
