Curated OER
Does a change in pH affect the growth and survival rate of aquatic plants?
Students determine if changes in pH affect the growth and survival rates of aquatic plants. They evaluate the optimal pH levels for the growth of aquatic plants.
Curated OER
pH Change and Brine Shrimp eggs
High schoolers determine if brine shrimp eggs hatch and develop more readily in an environment which has an acid or a basic pH. They evaluate the pH level which is optimal for the hatching and development of brine
shrimp.
Curated OER
Sense of Scale
Students examine the pH scale. They research common products and determine their pH level. They create their own pH scale and place their products in the appropriate place.
Curated OER
Stream Chemistry Monitoring
Learners 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
Pupils 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
Young scholars 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 activity 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.
