Curated OER
Teaching Modeling Water Quality
Students explore the basics of interpreting RUSS temperature and oxygen profile data. They are introduced to the Geographic Information Systems (GIS), particularly with respect to interpreting maps.
Curated OER
Water Quality And pH
Students determine the pH level of water and its effect on aquatic plants and brine shrimp eggs. This is a three part lesson that leads the student through the development of an understanding of water pH. They form a hypothesis and are...
Curated OER
Turbidy and Water
Students use observation skills in assessing the water quality of water samples in this activity and learn that the tastes and preferences of others can be different.
Curated OER
The Physiological Tolerance of Two Species of Protozoans
Students examine the differences in pH tolerance between the two species and relate these differences to their respective niches.
