BIOL 134 C002 EXPERIMENT DESIGN PLAN
COMPREHENSIVE STUDY GUIDE 2026 FULL
QUESTIONS AND SOLUTIONS GRADED A+
◍ What are independent and dependent variables?.
Answer: Independent variable is manipulated; dependent variable is
measured.
◍ What is the independent variable in a photosynthesis experiment?.
Answer: The different wavelengths of light.
◍ "B" represents the x-axis and is where the Independent Variable (IV) should
be plotted..
Answer: Which letter (A, B, or C) represents the axis where the Independent
Variable (IV) should be plotted?
◍ When is the rate of photosynthesis greatest?.
Answer: During the months of May, June, and July.
◍ What are examples of data presentation methods?.
Answer: Graphs, charts, tables, or maps.
◍ Kaylie's dependent variable (DV) is the mass of the balloon..
Answer: What is Kaylie's dependent variable (DV)?
◍ What is the independent variable in a sugar experiment with yeasts?.
Answer: The type of sugar given to the yeasts.
◍ The variable that is changed in the experiment..
Answer: Independent Variable (IV)
◍ Conduct a controlled test to answer a specific question..
Answer: Experiment
, ◍ What is the boiling point of water?.
Answer: Determined without the addition of any type of solute.
◍ An educated guess of the results of the experiment..
Answer: Hypothesis
◍ Yes, because the only variable that has been changed is the color of the
liquid. If all other variables are constant it would be a fair experiment..
Answer: Could this be used as the beginning of a fair experiment? Why?
◍ What is an example of a testable hypothesis?.
Answer: I predict that the rate of the enzymatic reaction will be highest at a
temperature of 40 °C.
◍ What must be constant in an experiment?.
Answer: Factors like the amount of sugar, water, yeast, temperature, and
light levels.
◍ What is the approximate boiling point of water?.
Answer: Approximately 331 °C.
◍ These are observations that describe "qualities" of something. These would
include characteristics such as texture, color, shape, and do not involve
counting or measuring..
Answer: Describe a qualitative observation.
◍ What is the independent variable in a gas volume experiment?.
Answer: The change in temperatures at which each gas will be measured.
◍ The variables that we keep the same (hold constant) so that they do not
change during the experiment..
Answer: Controls
◍ The x-axis is represented by letter "B"..
Answer: Which letter (A, B, or C) represents the x-axis?
◍ The standard against which the researcher compares the results from each
level of treatment..
Answer: What is a control group?
