What Pollutes the Pond?

ACTIVITY SHEET

Golden Pond has always been the favorite picnic spot

for people from Pondville. In the last year, algae have

taken over the pond, forming a thick, green mat on

the water surface. The pond smells bad now because

underwater plants, ﬁ sh, and other aquatic organisms

are dying. Underwater plants do not get the sunlight

and carbon dioxide they need. Decomposing algae use

up oxygen that ﬁ sh and other animals need.

Not long before the algae bloom began, the nearby

Big C Chemical Company started manufacturing a new

plant fertilizer. Big C uses the pond water to cool their

machines. The company claims that the fertilizer is

harmless to the pond. Other materials are dumped into

the pond by the SoClean Laundromat and the Pucker

Pickle Factory.

Your Job

You will be given some samples from the Big C Chemical

Company, the SoClean Laundromat, and the Pucker

Pickle Factory. You will test those samples and other

pollutants that might be in the pond. Your job is to ﬁ nd

out which pollutant is causing the algae bloom.
