Curated OER
Stream Chemistry Monitoring
Students become familiar with real-world gathering of chemical data. The experience how the science is done: the nature of analysis, data collection, interpretation, and presentation. They study a nearby body of water for their experiment.

Determining the Relationship Between pH and Hydrogen Ions with Microcomputer Based Lab (MBL) and/or Calculator Based Lab (CBL) Equipment
Learners find the relationship between the variables based on experimental data. They determine mathematical relationship between pH and the amount of hydrogen Ions in solution.
Curated OER
Teaching Modeling Water Quality
High schoolers 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
Learners determine the pH level of water and its effect on aquatic plants and brine shrimp eggs. This is a three part instructional activity that leads the student through the development of an understanding of water pH. They form a...
Curated OER
Turbidy and Water
Young scholars 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.
