Start by observing the living species around you. Choose two non-human species that interact with each other,such as bees and flowers,or predetor and prey species or two species that compete.Or, you can consider the effect of an enviromental factor on living non-human organisims,such as the effects of light or sound on plants or animals,or how food preference,or nutrient quanity/quality effect plants and animals.just a few examples.Your observations may lead you to many other types of questions about living organisims,their interactions and requirements for life. Start with an introduction and move through the steps of the scientific method, including observations/introduction, question, hypothesis, prediction, method/experiment, data collection, results (made up), and conclusion/discussion.
I think it would be easier to base an experiment on an organism and an environmental factor, as opposed to the relationship between two organisms. I would suggest something such as the relationship between plants and the amount of water they receive.
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. For example, I observe that usually plants need water in order to grow. However, there are some plants in deserts that hardly get any water and they still live. (These are my observations, but you would want to find additional plant data to add to this section specific to the plant you choose for your own experiment.)
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: Is there such a thing as too much water for a plant? or Does more water result in taller plants?
Hypothesis: Write a statement that ...
