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...

Under Pressure
Sometimes a little pressure isn't a bad thing! A collaborative instructional activity uses models to demonstrate how air pressure inflates and deflates the lungs. Participants use everyday materials to create models of the chest cavity...
NOAA
History's Thermometers
How is sea coral like a thermometer? Part three of a six-part series from NOAA describes how oceanographers can use coral growth to estimate water temperature over time. Life science pupils manipulate data to determine the age of corals...
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.

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
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...
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
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
Learners 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...

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.

Salmon Scavenger Hunt
Students go on a salmon scavenger hunt to find out about threats to salmon populations. They gather information about some of the reasons wild salmon have gone from such incredible abundance to relative scarcity, and about some of the...

AP Biology Lab Review
A seventy-two slide PowerPoint that reviews several lab explorations done in an AP Biology course. For each lab there is a description, concepts, and conclusions. Many pictures and graphics make this visually appealing, but it would not...

Simulating the Effects of Biodegradable Wastes on Dissolved Oxygen
Young scholars 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
Snapshot Day Definitions & Activities
In this watershed worksheet, students read through related definitions and complete 17 short answer questions about deposition and erosion in the Hudson River.
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
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...

Ecosystem Damage from Household Cleaners
Third graders assess the damage done to various ecosystems by cleaning products and discover how scientists test water quality. Using stream water and common household cleaning agents, they work in groups to test for pH levels. Once...
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
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
Acid Rain Experiments
Young scholars 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. Young scholars answer the...
Curated OER
Fishkill
Students 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 class...
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.
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.
