SCI 207 Week 1 Lab 1
Dissolved oxygen is oxygen that is
trapped in a fluid, such as water. Since many living organism requires oxygen
to survive, it is a necessary component of water systems such as streams, lakes
and rivers in order to support aquatic life. The dissolved oxygen is measured
in units of parts per million (ppm). Examine the data in Table 4 showing the
amount of dissolved oxygen present and the number of fish observed in the body
of water the sample was taken from; finally, answer the questions below.
1. What patterns do you
observe based on the information in Table 4?
1. Develop a hypothesis
relating to the amount of dissolved oxygen measured in the water sample and the
number of fish observed in the body of water?
1. What would your
experimental approach be to test this hypothesis?
1. What would be the
independent and dependent variables?
1. What would be your control?
1. What type of graph would be
appropriate for this data set? Why?
1. Graph the data from Table
4: Water Quality vs. Fish Population (found at the beginning of this exercise).
Describe what your graph looks like (you do not have to submit a picture of the
actual graph!!).
1. Interpret the data from the
graph made in Question 7.
Lab 1 – Exercise 2: Percentage Error
In the questions below, determine
the percentage error. Show your work on all problems.
1. A science teacher tells her
class that their final project requires the students to measure a specific
variable and determine the velocity of a car with no more than 2.50% error.
Jennifer and Johnny work hard and decide the velocity of the car is 34.87 m/s.
The teacher informs them that the actual velocity is 34.15 m/s. Will Jennifer
and Johnny pass their final project?
1. A locomotive train is on
its way from Chicago, IL to Madison, WI. The trip is said to last 3.15 hours.
When the train arrives in Madison the conductor notices it actually took them
3.26 hours. The train company prides itself on always having its trains to the
station within a 3.00% error of the expected time. Will the train company live
up to its reputation on this trip?
1. A coach tells his little
league players that hitting a 0.275 batting average, within 7.000% percentage
error, means that they had a really great season. Seven year old Tommy ended
the season hitting a 0.258 batting average. According to his coach, did he have
a great season?

Post-Lab Questions
1. Restate your hypothesis.
Was it confirmed or denied? How do you know?
1. Indicate which species was
removed during each round of the experiment.
1. Explain how the ecosystem
was affected by the missing species for each round of the experiment.
1. What actions do we as
humans engage in that can lead to extinction of any of these components?
1. What can we do to minimize
our impact on the ecosystem?
Lab 3 – Experiment 2: Diversity of
Plants
Post-Lab Questions
1. Restate your hypothesis.
Was it confirmed or denied? How do you know?
1. How many different kinds of
species did you find in your sample?
Which species is the most numerous
in your sample area? Which is the least numerous?
1. If each peat pot was a
sample you found in a group of wildflowers, would you determine based on the
diversity of flowers that the ecosystem is healthy?
1. How does biodiversity
contribute to overall health of an ecosystem?

Lab 4 – Experiment 1: The Effects of
Coal Mining
Post-Lab Questions
1. Restate your hypothesis.
Was it confirmed or denied? How do you know?
1. What, if any, change did
you observe within your water samples?
1. What type of substance
formed in the jars?
1. What effect do you predict
coal mining has on the environment?
1. What can be done to prevent
mine drainage from damaging the ecosystem?
Lab 4 – Experiment 2: Solar Energy
1. Restate your hypothesis.
Was it confirmed or denied? How do you know?
1. How did the revolutions of
the motor compare when the solar cell was held to an incandescent light source
vs. the sun as a light source?
1. Does increased exposure to
the sun’s light produce more current? Explain.
1. How did shading different
parts of the solar panel affect the motor’s output?
1. What effect did you observe
when different colored filters were placed atop the solar panel? What does this
indicate about different wavelengths of light?
1. How could you increase the
electricity generated by a solar cell during the day, when the sun’s angle is
constantly changing?

Lab 5 – Experiment 1: Modeling the
Water Cycle
Post-Lab Questions
1. Restate your hypothesis.
Was it confirmed or denied? How do you know?
1. Which water cycle processes
are represented in this model and by what components?
Which processes are not represented?
How could the model be altered to include these processes?
How would the “weather” be affected
if the water was at a decreased temperature?
Lab 5 – Experiment 2: Assessing
Infiltration
Post-Lab Questions
1. Restate your hypothesis.
Was it confirmed or denied? How do you know?
What formed on the inside of the
bags? What parts of the water cycle are represented in this experiment?
What condition showed the greatest
change? What force contributed to this change?
How would increasing the proportion
of land (sand) to water affect the amount of water vapor released?
How would drought conditions impact
infiltration and condensation from the ground?
