Primary science enquiries that are comparative tests have many similar features to fair tests in that one variable is changed, another variable is measured, and any other variables are controlled. The difference is that in a comparative test the variable that is changed is discrete rather than continuous, so children are comparing different cases/situations. Children regularly ask questions that lead to a comparative test, and these types of enquiries provide lots of opportunities to measure and collect data.
