    Start by observing the living species around you. Ever wonder why a pollinator is attracted to a particular flower, or what would happen to predator species if a particular prey species is eliminated? If you were a scientist you could do an experiment to answer your question.

    For this assignment, 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.

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

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

    Hypothesis: Write a statement that describes your explanation for the observation and question.

    Prediction: What do you predict as outcomes (results) of this experiment? (An "If ... Then" Statement)

    Controlled Experiment and Methods: Describe the experiment, variables to be held constant, variable to be tested, and controls. What data will be collected? Keep this simple and test only one variable at a time; holding the others constant.

    Results: Give the results (data) for the experiment. This will be created (imagined) by you since you are not actually doing this experiment.

    Conclusion / Discussion: Do you reject or accept the hypothesis based on the results? Discuss what this means in terms of the hypothesis, or need for additional experiments, or perhaps practical use of the results.

    Plants exhibit different types of growth movements, for instance, Geotropism. It is a growth movement exhibited by a plant in response to the force of gravity, thus known as Geotropism. The roots of a plant grow towards the force of gravity. Thus they are said to exhibit geotropism. Here the plants respond to a particular stimulus known as gravity or gravitational force. We usually observe that the shoot system of plants exhibits negative geotropism, whilst the root system exhibits positive geotropism.

    Question: Is the force of gravity responsible for geotropic movements in plants?

    Hypothesis: "The force of gravity has an important role as related to geotropic movements in plants."

    Prediction: "If a potted plant is placed ...
