1. Explain two ways you know what the independent variable is in this experiment. (Type of Activity) –
What you are changing, the variable which you the experimentor is manipulating.
a.
b.
2. Explain two ways you know what the dependent variable is in this experiment. (Heart Rate measured
in beats per minute.) – What you are measuring, the variable which you the experimentor is
measuring to determine any change.
a.
b.
3. What is the control in this experiment? __standing___ Explain how you know: _this is the
experiment where no change has occurred. This is serving as the baseline for comparison to the trials
where you the experimento has changed something.
4.
Why would this scientist want to include 3 trials and take an average heart rate? __to ensure accuracy,
help minimize error,
5.
6. If you were to graph this data, what kind of graph would be the best to use? ___bar graph. Explain
your answer: __1 qualitative (quality: color, something objective) variable, 1 quantative
(numerical, data driven) variable.
7. What kind of relationship should the graph show based on the data found in the table? __As the type of
activity increases in intensity with the test subject, the heart rate increases. ____________
8. Draw a line representing that relationship
on the skeleton graph to the right.
9. Label each axis of the skeleton graph
with the correct position of the IV and the DV.
Heart Rate vs. Type of Activity
Heart Rate vs. Type of Activity
Heart Rate (bpm)
10. Write in a good title for a graph containing
the data in the table above.
11. Where is the best place for a scientist/researcher
to report their findings so the scientific community
will be informed and begin to test/critique the research
for accuracy, comparison, and modification?
Type of Activity
Publish in scientific journal so other scientists can repeat the experiment and yield the same result.
Use the scenario and the data table below to answer the following questions:
Dr. Stanley is a Zoologist studying elephants and their habits. He decided to find out how many elephants
visited a particular watering hole each day, so he counted the elephants every day for a week. He then found
the mean, median, and mode for his data to help him communicate his findings.

mean--__ add all of the numbers in the set and divide by how many numbers are in the list answer: 21.285
b. median--_the list of numbers should be arranged in order from lowest to highest. The number in the middle or the
average of the two middle numbers is the median answer:

Define/Describe
Reproduce
All living things are composed of one (unicellular) or more (multicellular cells. Cells are the
smallest unit of living things.
All living things have the ability to reproduce to produce offspring.
Move
All living things respond to their environment
Acquire & Use Energy
To cary out life’s functions such as cellular respiration or photosynthesis. Energy is captured
from sunlight by plants and algae. The transfer of energy from one form to another is an
example of metabolism. All organisms require energy to grow, usually in the form of ATP.
Homeostasis
All living things must maintain a stable internal balance. Organisms act to keep their interior
conditions relatively constant.
All living things grow and replenish themselves. Cells individually reproduce, humans as a
group can reproduce.
All living things change over time. Evolution is a genetic change in a population over time.
Grow & Develop
Evolve
Genetics
8
All living things contain genentic material based on the replication and duplication of genetic
material. This genetic information is massed on to future generations in a process called
heredity.
Chapter 2—Chemistry of Life
Use the following word bank to fill in the missing words or phrases in the paragraph about water below.
acid
polar
adhesion
base
surface tension
capillary action
hydrogen (X3)
1-6
cohesion
8-14
hydroxide
oxygen
14. Water—Water molecules are composed of 2 atoms of hydrogen and one atom of oxygen. The position of these atoms causes
a water molecule to be slightly charged or what is called polar. The bond formed by the slight attraction of water molecules to one
another is called a hydrogen bond. It is a relatively weak bond, but strong enough to allow water to form an attraction with itself which
allows for surface tension. This attraction is called cohesion. This is how water drops are formed. Another form of attraction
between water and other polar substances is called adhesion. This is what allows water to move up the stem of a plant, also called
capillary action. If water molecules within a given substance break their individual bonds, the resulting particles are called ions; H+ is a
hydrogen ion and OH- is a hydroxide ion. Substances with larger numbers of H+ in solution are called acid their pH is between 1-6.
Substance with reduced numbers of H+ in solution are called bases their pH is between 8-14.

plasma membrane
Example: see pg. 142 HBIO
2. sexual reproduction- meiosis – involves sperm & egg cells (gametes)

1. P – Prophase I & II
2. M – Metaphase I & II
3. A – Anaphase I & II
4. T – Telophase I & II
