In science, a variable is any factor, trait, or condition that can exist in differing amounts or types. Scientists try to figure out how the natural world works.To do this they use experiments to search for cause and effect relationships. Cause and effect relationships explain why things happen and allow you to reliably predict the outcomes of ...
- Purpose Statement. The purpose statement helps readers understand what you planned to accomplish with your project. Explain the basic reasoning behind the project, why you found the project compelling, and how you think the results of your experiment will be beneficial.
- Hypothesis. The hypothesis is your rough estimation of what you believe would happen in your experiment. The hypothesis must answer a specific question related to your project.
- Materials List. The materials list is relatively straightforward. You will simply need to make a list of everything you used to complete your experiment.
- Procedures. Writing a procedure is necessary so you can perform each section of your experiment consistently. Also, much like the materials list, the procedure section helps another person carry out your experiment if desired.

In science, a variable is anything that can change or be different. It can be a thing (like a shirt or a jacket), a characteristic (like rough or smooth), or a situation (like sunny or cloudy).

Conducting a fair test is one of the most important ingredients of doing good, scientifically valuable experiments. To insure that your experiment is a fair test, you must change only one factor at a time while keeping all other conditions the same. Scientists call the changing factors in an experiment variables.
