2. Cypress Pond Park Planning
City officials planned the placement of the playground, hiking trail, and parking lot
around the pond. In response to concerns that polluted water would run off of the
parking lot and into the pond when it rains, they decided to place the parking area
as far from the pond as possible. A mulched playground was built on the other side
of the pond, and a new hiking trail winds all the way around the pond. Many trees
were removed to make room for the parking lot, playground, and hiking trail.
You job as an environmental scientist is to study the impact the park has on the
pond ecosystem. The pond contains trout and catfish. Catfish are very tolerant of
pollution, but trout are much more sensitive and die off easily when exposed to
excessive pollutants. Before the land and pond were disturbed by the construction
of the playground, hiking trail, and parking lot, you counted the number of fish in
the pond. At that time, Cypress Pond contained 100 trout and 100 catfish. Now you
need to design an experiment to monitor the park’s impact on the populations of
trout and catfish over the next 12 months.
1. What is the purpose of your experiment?
2. Develop a hypothesis for the experiment.
3. What are the dependent and independent variables of your experiment?
3. Monitoring the Biodiversity of Cypress Pond
Procedure
In this section, you will create a step-by-step procedure for testing and monitoring
the number of trout and catfish in Cypress Pond. You must monitor them once per
month for 12 months after the park is built.
4.Data from Monitoring the Biodiversity of
Cypress Pond
Listed below are the results of your hard work. You monitored the populations of
trout and catfish in Cypress Pond every month for a year after the park was
developed. For each month, add the amount of both types of fish together. Write
this total in the Total Number of Fish column. Present these results by creating a
line graph.
Month Number of Trout Number of
Catfish
Total Number
of Fish
January 100 100
February 90 95
March 85 93
April 83 92
