2. What is the primary function?To establish and quantify causal relationships between variables
3. What is an experiment and why is it important?An experiment is a carefully planned test that helps scientists prove or disprove ideas. It shows how one change can cause another, giving clear evidence for science.
4. How do scientists make sure an experiment is reliable?They repeat the test many times and let other scientists do the same. If everyone gets the same results, the experiment is trusted.

Hypothesis Testing: The process of using experimental data to determine the validity of a proposed explanation.
Independent Variable: The factor deliberately changed or manipulated by the researcher in an experiment.
Dependent Variable: The outcome or factor measured in an experiment, expected to change in response to the independent variable.
Control Group: A group in an experiment that does not receive the experimental treatment, serving as a baseline for comparison.
