The Science Buddies website aims to promote deep understanding of scientific research through student science fair projects. This segment of the website provides explicit help in understanding variables and designing a fair test. The page includes:

1) Background information: What are variables in scientific inquiry and why is it important to identify them?
2) Eight short examples of scientific questions with independent and dependent variables identified.
3) Sample write-up of a simple experiment with hypothesis, experimental groups described, and variables to be controlled
4) Student checklist for selecting good variables

1. The Nature of Science

1B. Scientific Inquiry
  • 3-5: 1B/E1. Scientific investigations may take many different forms, including observing what things are like or what is happening somewhere, collecting specimens for analysis, and doing experiments.
  • 6-8: 1B/M1b. Scientific investigations usually involve the collection of relevant data, the use of logical reasoning, and the application of imagination in devising hypotheses and explanations to make sense of the collected data.
  • 6-8: 1B/M2ab. If more than one variable changes at the same time in an experiment, the outcome of the experiment may not be clearly attributable to any one variable. It may not always be possible to prevent outside variables from influencing an investigation (or even to identify all of the variables).
  • 9-12: 1B/H2. Hypotheses are widely used in science for choosing what data to pay attention to and what additional data to seek, and for guiding the interpretation of the data (both new and previously available).

  • Science findings are limited to questions that can be answered with empirical evidence. (5)
Science is a Human Endeavor (3-12)
  • Science affects everyday life. (3-4)
  • Scientists and engineers are guided by habits of mind such as intellectual honesty, tolerance of ambiguity, skepticism, and openness to new ideas. (6-8)
