Health of Aquatic Life a Real Problem
Learners explore the health of aquatic life in this science lesson They measure and track the oxygen level in the water to determine the health of the aquatic life. They collect this data using the TI explorer to graph and analyze their...
Curated OER
Take a Dip: The Water in our Lives
Students collect water samples from local freshwater sources and test for pH, dissolved oxygen, nitrates, macroinvertebrates, phosphates, and coliform bacteria in order to determine water quality for each source.
Curated OER
Solutions and Suspensions
Students 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...
Curated OER
Message in the Bottles
High schoolers identify the three realms of the Arctic Ocean, and describe the relationships among these realms. They explain the relationships between gross primary productivity, net primary productivity, and respiration.
Curated OER
Save Your Breath
Students discuss metabolism. In this metabolism lesson, students evaluate evidence form a research report and discuss the basis for hypothetical metabolic adaptations to low-oxygen environments in the anchialine caves.
Curated OER
Primary Producers
Students examine the role of carbon in the oceans and how phytoplankton determine the levels present. In groups, they practice measuring primary productivity using two methods. They use the internet to research the role of phytoplankton...
Curated OER
Teaching about the Chemistry of Oxygen Solubility
Students explore solubility of gases in water, Henry's Law, LeChatelier's Principal, and supersaturation of gases in water.
Curated OER
Why Is Our Stream Changing?
Learners test turbidity, pH, oxygen content and temperature of local stream. In this earth science lesson, students collect and record data from the experiment. They analyze findings and present it to class.
Curated OER
The Dead Zone in the Gulf of Mexico
Students explore hypoxic (low oxygen) conditions in the Gulf of Mexico. In this ocean habitat lesson, students hypothesis, design and implement an experiment to explain the existence of the "Dead Zone" in the Gulf of Mexico.
Michigan Sea Grant
Water Quality
Learners observe water samples and measure the samples' water quality. Students develop their own criteria for measuring water quality and test for temperature, acidity, oxygen levels, turbidity, conductance, sediment and hardness.
Curated OER
Measuring Water Quality
Learners are introduced to the various methods of measuring water quality. In groups, they test various water samples using the different methods, writing them down for pH, oxygen, salinity, and nitrate levels. They use their data to...
