Dissolved Oxygen and Photosynthesis: 1
High schoolers are taught that plants produce oxygen underwater, and they design an experiment that test this question. They discuss whether plants give off oxygen, and how to measure this. Students measure the increase in dissolved...
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
Learners 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...
Curated OER
Amounts of Dissolved Oxygen in Various Bodies of Water
Students test water to determine the dissolved oxygen content while displaying the proper use of testing instruments while visiting water testing sites. They determine if the amount of dissolved oxygen is appropriate for the tested...
Curated OER
Water Quality and Dissolved Oxygen
Students investigate the relationship between dissolved oxygen and organic materials and aquatic organisms. This is a 3-lesson plan series in which students explore dissolved oxygen and then design an experiment testing the effects of...

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
Simulating the Effects of Biodegradable Wastes on Dissolved Oxygen
Students evaluate the relationship between biodegradable waste and dissolved oxygen in water. In this biodegradable wastes lesson students complete a lab activity in groups then analyze their results.
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
Dissolved Oxygen Activity
Students explore why dissolved oxygen must be present for aquatic life to survive. They explain what dissolved means. Students discuss what dissolved oxygen is. They watch as the teacher lights two candles and place a jar over one of...
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...

Why Does Water Dissolve Sugar?
Did you know that if you wait long enough, the M on the outside of an M and M will float to the surface when submerged in water? Learners observe the sugar coating of an M and M while it is dissolving in water. They explain how this...

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
Too Much Oxygen or Too Little?
In this oxygen worksheet, students analyze date about the oxygen levels in a river to determine the cause of the dying fish. This worksheet has 2 graphs, 12 short answer questions, and 2 graphic organizers.

Weathering and Soil
From types of rocks to types of weathering, learners gain knowledge on minerals, composition of soil, and the effects of weathering on Earth.
Curated OER
Dissolved Oxygen in an Aquatic Ecosystem
Students explain why dissolved oxygen is important in aquatic ecosystems. They evaluate the optimal dissolved oxygen levels for living organisms.

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
Dissolved Oxygen
Students discuss the relationships between dissolved oxygen in a stream, stream temperature, organic waste loads, and stream conditions by studying and using a model of dissolved oxygen in the stream.
Curated OER
Dissolved Oxygen
Students examine characteristics of dissolved oxygen. Given a stream temperature, and stream conditions, students study the relationships of the dissolved oygen in a stream, in organic waste loads.

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
Testing the Waters
Students use test kits to measure the level of chlorine, iron, sulfide, and dissolved oxygen in tap (drinking) water and stream water. They post and evaluate the results of these water quality tests.
Curated OER
Photosynthesis and Respiration
Students comprehend the relationship between plants and animals in an aquatic ecosystem. They predict the effects of low dissolved oxygen on the organisms. Students create microcosms with plants, animals, or both. They determine which...
