Explanation:

1. Listening to animal sounds uses sensory input to gather data, which is making observations.
2. The scientific method follows the sequence: ask a question, form a hypothesis, test it, analyze results, draw conclusions, and retest if needed.
3. A hypothesis does not restate the question; it is a testable, predictive if/then statement.
4. A correct hypothesis uses a clear if/then structure to state a testable prediction comparing conditions.
5. Using senses to gather information is defined as observation.
6. The scientific method is a structured step-by-step process for problem-solving.
7. The intentionally changed variable in an experiment is the independent variable (also called experimental variable, but independent is the standard term here).
8. The variable measured in response to changes is the dependent variable.
9. The independent variable is the factor intentionally changed, which is incubation temperature here.

Answer:

1. c. Making observations
2. a. Ask a question, make a hypothesis, test the hypothesis, analyze results, draw conclusions, retest.
3. c. It should restate the question
4. a. If a tennis ball is frozen, then it won't bounce as high as one that is not frozen.
5. a. Observation
6. a. Scientific Method
7. c. Independent variable
8. d. Dependent variable
9. c. The temperature
