What Is a Constant in a Science Fair Project?
Science fair projects allow students to learn about the scientific process of forming and testing a hypothesis. The term “constant” or “constant variable” refers to the portion of the science fair experiment that remains the same throughout the testing process.FunctionA “variable” is something that alters the experiment and helps to either prove or disprove a hypothesis. Science Kids at Home notes that “constant variables” however, never change throughout the experimentation, increase experiment accuracy, and lend credibility to the science fair project. Science Buddies notes that both constants and variables must be measurable.ImportanceSuccessful science fair projects conduct several trials to prove or disprove the hypothesis. By retesting the experiment, students will learn more about the underlying concept of their topic and the important relationship between the constants and variables.ExampleWhen testing something such as the melting point of an ice cube, the room temperature wou
