Read each question carefully and provide thoughtful, detailed answers. This worksheet will assess your understanding of experimental design principles.
1. Differentiate between an independent variable and a dependent variable in the context of a scientific experiment.
2. Explain the purpose of a control group in an experiment. Provide an example.
3. Which of the following is the most important characteristic of a good hypothesis?
It is complex and uses scientific jargon.
It is a proven fact.
It is testable and falsifiable.
It always predicts a positive outcome.
4. What is the primary role of replication in experimental design?
To increase the number of variables.
To ensure the experiment is cheap to conduct.
To confirm the reliability and validity of results.
To make the experiment more complicated.
5. A scientific experiment should ideally have only one variable that is purposefully changed by the researcher.
6. Factors that are kept constant throughout an experiment are known as .
7. The process of randomly assigning subjects to different experimental groups helps to minimize .
8. A conclusion is formed before an experiment is conducted.
True
False
9. A valid experiment must always prove the initial hypothesis to be correct.
True
False
10. Design a simple experiment to test the hypothesis: 'Plants grow taller when exposed to classical music.' Identify the independent variable, dependent variable, control group, and at least two controlled variables.
