Read each question carefully and provide thoughtful, detailed answers based on your understanding of scientific experimentation.
1. In a scientific experiment, which variable is deliberately changed by the experimenter?
Dependent variable
Independent variable
Control variable
Extraneous variable
2. What is the primary purpose of a control group in an experiment?
To introduce bias into the results
To provide a baseline for comparison
To manipulate the independent variable
To observe all possible outcomes
3. A testable prediction about the outcome of an experiment is called a .
4. Repeating an experiment multiple times to ensure reliability is known as .
5. Design a simple experiment to test if the temperature of water affects how quickly sugar dissolves. Identify your independent variable, dependent variable, and at least two control variables.
6. Explain the difference between qualitative and quantitative data, providing an example of each in the context of an experiment.

True
False
Match each term with its correct definition.
9. Hypothesis
a. The variable that is measured or observed
10. Dependent Variable
b. A proposed explanation made on the basis of limited evidence as a starting point for further investigation.
11. Independent Variable
c. Factors kept constant to ensure a fair test
12. Control Variables
d. The variable that is intentionally changed by the experimenter
