Every science fair project can be broken into eight primary sections. When you present your project to a class or the judges of the science fair, you will need to ensure that each of the main eight elements is adequately represented on both your presentation board and your lab reports.

The scientific method involves asking a question, doing research, forming a hypothesis and testing the hypothesis via an experiment, so that the results can be analyzed. Every successful science experiment must include specific types of variables. There must be an independent variable, which changes throughout the course of an experiment; a depende...
Let's say that a scientist is performing an experiment to test the effect of different lighting on houseplants. In this case, the lighting itself would be the independent variable, because it is the variable that the scientist is actively changing, over the course of the experiment. Whether the scientist is using different bulbs or altering the amo...
Dependent variables are the traits that a scientist observes, in relation to the independent variable. In other words, the dependent variable changes depending on the alterations made to the independent variable. In the houseplant experiment, the dependent variables would be the properties of the plants themselves, which the scientist is observing ...
A controlled or constant variable does not change throughout the course of an experiment. It is vitally important that every scientific experiment include a controlled variable; otherwise, the conclusions of an experiment are impossible to understand. For example, in the houseplant experiment, controlled variables might be things such as the the qu...
Identifying control variables, independent and dependent variables is important in making experiments fair. Knowing about variables can help you make scientific predictions and test them.
Aug 16, 2018 · Correlation: A correlation is a relationship between two variables that can be used to predict the behavior or value of one variable if the other is known. Correlation is not the same as causality. In other words, correlating two variables doesn’t always imply one causes the other.
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.
Variables in Your Science Fair Project. Scientists use an experiment to search for cause and effect relationships in nature. In other words, they design an experiment so that changes to one item cause something else to vary in a predictable way. These changing quantities are called variables.

May 6, 2020 · The independent variable is the factor the researcher changes or controls in an experiment. It is called independent because it does not depend on any other variable. The independent variable may be called the “controlled variable” because it is the one that is changed or controlled.
