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.
