8. Chapter 1 Review Questions
1. What term describes proposed answer to a scientific question? (A) observation (B) independent variable (C) dependent variable (D) hypothesis 2. What condition in an experiment does a biologist manipulate? (A) independent variable (B) dependent variable (C) control (D) constant 3. Provide an example that displays the importance of and the difference between constants and controls.
Why is “educated guess” not the best way to describe a hypothesis? Think about what “educated” means.

9. Answers
1. What term describes proposed answer to a scientific question?
(A) observation (B) independent variable (C) dependent variable (D) hypothesis
2. What condition in an experiment does a biologist manipulate?
(A) independent variable (B) dependent variable (C) control (D) constant
3. Provide an example that displays the importance of and the difference between constants and controls.
Answers vary. Constants- conditions that do not change. Control- treated like the experimental group except for the independent variable being studied. Used for comparison.

Quality/quantity

11. Answers cont. 4.Which is the correct sequence of scientific inquiry?
Don’t fixate so much on the number of steps. Understand the process involves observing, hypothesizing, experimenting, analyzing, and evaluating/concluding
