Asking Questions: Generating Hypothesis

The purpose of this exercise is two fold--- First to give you practice in generating hypothesis, and second to demonstrate that the quality of science is improved by open discussions among people interested in an idea.

Asking Questions

Observe the video provided by your teacher, write down as many questions as you have over the next few minutes. Post at least one question as directed by your instructor.

As a class come to a consensus over the question(s) you think are the most interesting and well written. 

Generating Hypothesis

The questions generated by the group can form an ideal base for generating hypothesis (or set of hypotheses). A Hypothesis is a proposed answer to a question; alternative hypotheses are alternative answers. Remember
  • A hypothesis must be testable. For example, if your question is "are the leaves in the shade larger than those in the sun?" Your two hypothesis are H1: leaves in the shade will have greater surface area than those found in the sun, H2: leaves in the shade will be smaller in area than those found in the sun.
  • "testable" also means that the question cam be answered in the time available, with the tools available, and within the analytical capabilities of the group. It is important to restrict the number of variables, yet it is often one of the more difficult tasks to accomplish.
