    Writing an Experiment using the Scientific Method: Example

    Choose two non-human species that interact with each other, such as bees and flowers, or predator and prey species, or two species that compete. Or, you can consider the effect of an environmental factor on living non-human organisms, such as the effects of light or sound on plants or animals, or how food preference, or nutrient quantity / quality affect plants or animals. These are just a few examples. Your observations may lead you to many other types of questions about living organisms, their interactions, and requirements for life.

    Start with an Introduction/Observation and move through the steps of the Scientific Method as outlined below. Your paper should follow this format. Remember, you don't have to actually do the experiment, just write what you would do to test your hypothesis.

    Can you also please explain the difference in the different types of variables? I'm a little confused about those.

    I would recommend basing your experiment on an organism and an environmental factor, as opposed to the relationship between two organisms. I would suggest something such as earthworms and light.

    Start with an Introduction/Observation and move through the steps of the Scientific Method as outlined below. Your paper should follow this format. Remember, you don't have to actually do the experiment, just write what you would do to test your hypothesis.

    Introduction: Describe your observation. Include background information about your observation that you have found using references. List and cite references using APA format.

    I observe that usually earthworms are underground or under rocks, but I also see dead earthworms out in the open on sidewalks. (These are my observations, but you could find additional earthworm data to add to this section if your professor requires sources. However, some of the best observations are those made by someone just being curious.)

    Question: Ask a question about the observation that you have made.

    When developing a problem or question for a particular situation, you are simply stating the obvious. This is usually the easiest part of the scientific method. Examples might include: Where do earthworms live? Or, do earthworms prefer darkness or light? Something more closely related to the second one will be easier around which to generate a ...
