Seventy percent of the earth's surface is covered in water.
What's in all that water? A lot of life! This lab explores the
impact of pollution on water microorganisms using a bioassay
with Daphnia (water fleas). Students will measure the toxicity
of common household pollutants by examining survival rates of
Daphnia when they are exposed to these chemicals. In addition,
students will classify a variety of water organisms into
kingdoms and phyla.  Back to Labworks!
