The presentation of your experiment is an important component of this exercise. The results of scientific studies are reported through written communication and oral communication. Oral communication through presentations is one of the most important skills to practice as an undergraduate and is not a component of many undergraduate classes. A recent review by the National Science Foundation has indicated that one area of deficiency for students who graduate with four-year degrees in science is oral communication, and a request for science curricula that improve oral communication has been advocated on a national scale (Shaping the Future, NSF 96-139).

Each group will give a presentation of their experiment. Presentations should take from 8 to 12 minutes with several minutes for questions following the presentation. All students in the group must participate in the presentation and present some portion of the material. The presentations should include the following components:

Introduction — State the problem you tested and provide a logical progression to the statement of your hypotheses.

Methods — Give a brief overview of your methods including a statement explaining variables and experimental controls.

Results — Explain results of your experiments using visual aids — graphs and tables.

Discussion — Do you reject or fail to reject your hypothesis? Was your experiment valid and reliable? Were there problems with your experiment? Do you have a new hypothesis or a modified hypothesis? What would you do next? (Be sure to provide evidence for contentions.)
