Use this page to explore a hillside spring.
This spring is a hillside or gravity spring; the
water does not issue under artesian pressure, but as seepage,
in which the water percolates from small fractures in the rock.
Factors to consider:

Pond
size (length, width, depth)
Rainfall
Water temperature
Water pH
Stream length, flow rate

Count & identify: |
- Algae (pdf)
- Protozoa and microscopic animals
- Aquatic insects; mosquito larvae separately
- Plants. Species, number, area covered.
- Amphibians

- Chlorophyll
- Nitrogen content as nitrate ion

Before beginning, talk with the
instructor to see the spring and to develop your work plan.
1. Title page (1)
2. Six (no more and no less) content pages. The
text should consist of a student-worded analyses of your research
during long hours in a library and at the spring. Do
not quote authors: Put the information in your own
words and cite your reference.
a. Bimonthly data. (15)
b. Construct a food chain for the pond. (10)
c. Graph one or more of the biological parameters against a
physical factor or another biological factor. (5)
d. Explain the relationship between the factors that you graphed.
(10)
e. Discuss the (beneficial, neutral, negative) significance
of the spring. (5)
3. Read
about the organisms you identified and answer the following
questions:
a. Identify two predators from your food chain:_______________
& _______________
Contrast the two predator types (e.g., speed, camouflage, stealth).
How do they avoid competing with each other?
(10)
b. Identify
some prey defenses, using specific examples from your food chain.
(10)
c. Identify
two herbivores from your food chain:______________
&________________
How do they avoid competing with each other? (10)
4. Literature cited page*.Include
5 references in correct format.
(10) You must use at least 3 journal articles; all references
may not be books and websites. References must be cited somewhere
in the content. Do not include references prior to 1980.
5. Three figures on three separate pages.
a. Each figure must have a legend.
b. Refer to each figure in the body of the text.
c. Figures can include (one) photograph or picture; chemical
formulae; metabolic pathways; phylogenetic tree; survivorship;
population trends; graphs. (9)
