Unit One: The Nature of Science and Biology

N-Journal: Conducting an Experiment
For a science class project, Sandy wants to test the effect of rap music on pea plant growth. She plays loud rap
music 24 hours a day to a series of pea plants grown under light and watered daily. At the end of her experiment,
she concludes that rap is conducive to plant growth. Sandy receives a low grade on this experiment from her
teacher.
Why did Sandy’s teacher give a low grade for this experiment? What was the key problem with it? How could
Sandy change her experiment to fix the problem? Rewrite the experiment so it will receive a better grade.

N-Discussion: Unifying Themes
Previously, you were asked to take a moment to write down on a sheet of paper your own list of the
characteristics of life, and to keep it available to compare our list to your own list.
Were there any characteristics that you did not originally have on your list? W ere there any you had that we did
not? Compare what you wrote with that of the other students in your class.

Please try to post and reply to other student discussions within one week so your assignment can be
graded in a timely matter.

N-Journal: Characteristics of Life

Here are six living things: a person, an oak tree, a mushroom, an amoeba, seaweed, and a bacterium. What
features do they all have in common? How do they differ? Use the Internet to aid your research.

10 Purpose of this lab (What is the goal of this lab?
What question is it trying to answer or what
problem is it trying to explain?)
10 Hypothesis (After reading the lab instructions-but
before starting the lab-record your best “educated
guess” about what will happen in the experiment.
What hypothesis can you generate about the
effect of adding salt to water?)
10 Materials (List the materials used in the lab)
10 Procedure (List the procedure that you followed)
10 Data (Data Table)
10 Graph (Data graph)
10 Analysis (Analyze the data you collected in the lab.
How does the data presented above relate to the
hypotheses you generated earlier in lab? Are any
hypotheses disproved by your experiment? Use
your graph to determine the boiling point of a
solution made with 2 ½ tablespoons. This use
of a graph has generated a hypothesis that a 2
½ tablespoon solution boils at ____degrees C.
Prepare a 2.5 M solution and verify your
hypothesis.)
10 Conclusions (After conducting the experiment, how
would you now explain the problem(s) or answer
the question(s) raised when you described the
purpose of the lab? Be sure to base your answer
on the data you collected. If you are given a
solution of unknown concentration, can you
determine its concentration? Explain.)

method in everyday life? List examples.
