Weathering and Soil Formation
A set of 27 slides systematically shows how weathering, erosion, and deposition contribute to soil formation. Both chemical and mechanical weathering are described, as are resulting soil layers and properties. There is no longer any need...
Curated OER
Diurnal Cycling Experiments
Students carry out an experiment to monitor diurnal fluctuations in dissolved oxygen, carbon dioxide, pH, and water temperature. They determine the CO2 and pH of the samples (and optionally, dissolved oxygen). Students complete their...

Using A Volunteer Acquired Database Constructed On The Internet, Examine the Relationship between Dissolved Oxygen and Water Temperature
Ninth graders access a database and open a spreadsheet. In this oxygen and water temperature lesson students save the database, sort it and generate scatter plot graphs.
Curated OER
Dissolving Solids and Gases
In this dissolving solids and gases activity, students learn that the process of dissolving gas is opposite of the process of dissolving solids. Students answer 3 critical thinking questions about dissolving gases and solids in solutions.

Under Pressure
Sometimes a little pressure isn't a bad thing! A collaborative lesson uses models to demonstrate how air pressure inflates and deflates the lungs. Participants use everyday materials to create models of the chest cavity to simulate how a...
Curated OER
Reading the River
In collaborative groups, young ecologists measure the temperature, pH, and dissolved oxygen for three different freshwater samples. They examine each sample with a microscope and record observations on the microorganisms in the pond...
Curated OER
What is Dissolved Oxygen?
Students experiment with the LaMotte Winkler-Titration Test Kit to try to answer the question of what is dissolved oxygen. They explore all the possible ways to test for dissolved oxygen and brainstorm all the obstacles that can affect...
Curated OER
Fishkill
High schoolers analyze data to determine the effect of thermal pollution on a certain species of fish. They graph temperature and dissolved oxygen and make inferences on the impact a change in temperature could have on the fish. As a...
NOAA
The Dead Zone
The fifth installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program defines dead zones and how they form. Pupils then examine data from the Gulf of Mexico to determine dead zone formation.

Oxygen Levels and Aquatic Plants and Animals
Students design an experiment to test the effects of a change in the amount of dissolved oxygen of water on aquatic plants and animals. Questions are offered for exploration and experiment design. Results are tabulated and conclusions...
Biology Junction
Water, Solutions, pH, and Buffers
What common chemical includes safety warnings for being harmful if swallowed or inhaled, causes serious eye damage, and needs to be cleaned up immediately if spilled on the floor? Surprisingly, the dangerous chemical turns out to be...

Monitoring Estuarine Water Quality
Students analyze water quality data from real data. In this environmental science lesson, students examine how salinity and dissolved oxygen affect the living organisms in the estuary. They interpret graphs to support or disprove a...
Curated OER
Solutions and Suspensions
Learners explore matter by conducting an in class demonstration. In this liquid mixture lesson, students identify the difference between a solution in which a solid dissolves into liquid, and a suspension where the solid doesn't dissolve...
