    Study Notes

    Testable Questions in Science

    • A testable question is a question that can be answered through experimentation and data collection.
    • Testable questions always involve variables that can be manipulated and measured.

    Format of Testable Questions

    • A commonly used format for testable questions is: "Does [independent variable] affect [dependent variable]?"

    Variables in Scientific Experiments

    • A variable is a factor that can be changed or manipulated in an experiment.
    • An independent variable is the factor that is intentionally changed or manipulated in an experiment.
    • A dependent variable is the factor that is being measured or observed in response to the independent variable.

    Identifying Variables in Testable Questions

    • The independent variable is the factor that is identified as being changed or manipulated in the testable question.
    • In the question "Does changing the height of the ramp affect the speed of the car going down the ramp", the dependent variable is the speed of the car.
    • In the question "Does changing the amount of light affect the growth rate of plants", the independent variable is the amount of light.
    • In the question "Does the temperature of water affect the time it takes a sugar cube to dissolve", the dependent variable is the time it takes for the sugar cube to dissolve.

    Parts of a Testable Question

    • A testable question requires two parts: the independent variable and the dependent variable.

    Controlled Variables

    • Factors that are kept constant in an experiment are called controlled variables.

    Creating a Testable Question

    • The first step to turn a general question into a testable question is to identify the variables that can be manipulated and measured.
    • Examples of things you can change to make "What makes plants grow best" a testable question include light, water, and temperature.
    • When turning a general question into a testable one, you need to identify specific effects that can be looked for.

    Controls in an Experiment

    • Controls in an experiment refer to the standard or normal conditions under which the experiment is conducted.
