Read each question carefully and provide your best answer based on your understanding of experimental design principles.
1. Which of the following is the BEST definition of a hypothesis?
A statement that summarizes the results of an experiment.
A testable prediction about the relationship between variables.
A conclusion drawn from observations without experimentation.
A general principle that explains a natural phenomenon.
2. In an experiment, what is the purpose of a control group?
To be exposed to the independent variable.
To provide a baseline for comparison.
To measure the dependent variable.
To introduce bias into the experiment.
3. The variable that is changed or manipulated by the experimenter is called the variable.
4. The variable that is measured or observed in response to the change is called the variable.
5. Factors that are kept the same throughout an experiment to ensure a fair test are called .
6. Design a simple experiment to test if different brands of fertilizer affect plant growth. Identify your independent variable, dependent variable, and at least two controlled variables.
7. A good hypothesis must be testable and falsifiable.
