Curated OER
Dissolved Oxygen and Temperature
Students are shown how temperature affects dissolved oxygen and they create a graph showing this relationship. They think about the adaptations of animals to live in different water temperatures. Students test four different water...
Curated OER
Dissolved Oxygen Introduction
Students are shown how dissolved oxygen enters the water. They are taught the difference between a water sample that has been exposed to the air and one that has not. Students brainstorm what organisms need to survive. They use dissolved...
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...

What's in the Water? - Stream Side Science
Here is a complete activity in which young biologists or ecologists test the pH, dissolved oxygen, turbidity and temperature of stream water. The class visits an actual stream and makes observations of the site. They use scientific...
Curated OER
Dissolved Oxygen and Respiration
Students are presented with the question, "Do plants that grow underwater use oxygen?" They create an experiment to test the presence of dissolved oxygen in the water using provided materials. Student experiments include a control jar as...
Curated OER
What If There's No Light?
students discuss the importance of light and the consequences of living without it. Using a plant as a demonstration, students predict and observe what happens to a plant when it does not receive enough light. In groups, they experiment...

The Effects of Heat and Acid on the Enzyme Catalase
How quickly do enzymatic reactions occur? Assist the class as they examine heat and pH change to determine the rate of chemical reactions using catalase as an enzyme. Watch them "glow" with excitement!
Curated OER
What Do Fish Want?
Topics covered by the notes in this presentation are water components, what is acceptable in terms of water quality for the fish living in it, ammonia and natural filtration, nitrates, and dissolved oxygen. Each slide has the same...
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...
Omaha Zoo
Monitoring Amphibians
What sort of shoes do frogs wear? Open toad sandals. If your scholars want experience collecting field samples, this is the lesson for you. After learning the proper way to collect field samples, pupils catch amphibians to test for...

Let's Learn About Stewardship and River Basins
What does it mean to be a good steward? Middle school environmentalists learn to care for their state's waterways through research, a guest speaker, and poster activity. Groups must locate and learn more about a river basin and the human...
Curated OER
Teaching about the Effect of pH on Aquatic Organisms
Learners perform experiments to determine the PH, acidity, and buffering qualities of a lake that make them sensitive to acid deposition.
Curated OER
Acids and Bases
In this acids and bases worksheet, students complete 32 fill in the blank and short answer questions on acidity or alkalinity. They color molecular diagram according to the key.

Sustainability: Learning for a Lifetime – The Importance of Water
Water is essential for life—and understanding the importance of clean drinking water is essential in understanding sustainability! Show your environmental science class the basics of water testing and treatment through a week-long...
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...
Curated OER
Acids and Bases
In this acids and bases worksheet, high schoolers review the characteristics of acids and bases, pK values, factors that change the rate of reactions, and catalysts. This worksheet has 17 multiple choice questions.

Is My Water Safe?
Learners discuss what makes their drinking water safe and unsafe. They locate and visit a local tributary and test the water's pH, hardness, dissolved oxygen, and total alkalinity. They compose a summary paragraph about the tests and...
Curated OER
Nature and Fitness Trail
Students plan stations for a nature and fitness trail and construct an accompanying e-Book for extended descriptions at each station. Data on the human impact on the environment is gathered in this lesson.
Curated OER
Water Quality Monitoring
Students comprehend the four parameters of water quality. They perform tests for salinity, dissolved oxygen, pH and clarity or turbidity. Students comprehend why scientists and environmental managers monitor water uality and aquatic...
Curated OER
How about a Little Give and Take?
Middle schoolers design a closed system to test the relationships between plants and animals. They monitor abiotic fluctuations within this living system by using a chemical test kit. They observe how living organisms respond to...
Curated OER
Solutions and Solubility Review
In this solutions and solubility review worksheet, students are given main ideas about intermolecular forces, concentrations of solutions, molar solutions, ionic equations, solubility rules, acids and bases and titrations. Students...
Curated OER
Acid Rain Experiments
Learners define the term acid rain, and the causes of acid rain. They locate regions where acid rain is most affected, and what can students deduce from maps of geology and soils in New York State. Learners answer the questions why are...
Curated OER
Water Quality
Students play the role of scientists testing for water quality in the area. In this ecology lesson, students determine the water sample's pH, temperature, dissolved oxygen and turbidity. They write a journal reflection after the activity.
