Dissolved Oxygen and Photosynthesis: 1
Students 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 oxygen...
Curated OER
Dissolved Oxygen and Temperature
Young scholars 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...
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...

Eyes on Dissolved Oxygen
Learn about the factors that affect the way oxygen dissolves in salt water with a chemistry lab. After studying the molecular structure of water, young scientists figure out how aeration, temperature, and organic waste affect dissolved...
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
Water Quality and Dissolved Oxygen
Students investigate the relationship between dissolved oxygen and organic materials and aquatic organisms. This is a 3-lesson series in which students explore dissolved oxygen and then design an experiment testing the effects of changes.
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
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...
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.
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's This? Breathing
Crazy fact: Some animals can survive months without oxygen. An online resource describes some unique ways animals collect oxygen and even live without it for an extended time. Learners read about these special animals and use pop-up...
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...
