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...

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...

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...

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...

Learners 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...

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...

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...

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...

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...

Students are given the unique opportunity to see the contrast between parts of a leaf that have photosynthesized and parts of the leaf that have not. This visual image helps students see the results of this biological process. At the...

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...

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...

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...

The Deepwater Horizon oil spill directly impacted an area of the Gulf of Mexico the size of Oklahoma. A marine biology lesson looks at the impact of an oil spill on the deeper parts of the ocean. Scholars download actual data collected...

Students are able to use a secchi disk to measure the turbidity of water by determining the depth at which the sechi disk is no longer visible and using the data in a formula to quantify the results. They are able to use Vernier probes...

What do a dead fish, conservation, and paint have in common? The answer is a great lesson about fish anatomy, fun print making techniques, and unsustainable fishing practices. The class will start by making fish prints with a...

When a candle burns down, what happens to the mass that appears to be shrinking? Lesson begins with a demonstration of the chemical reaction of a candle burning. Then scholars use atom models to observe conservation of mass...

Learners create a model of a salt marsh to discover the impact of pollution and human activities on water-based habitats including bays and the ocean. They recognize the relationship between natural and developed areas. Students impact...

Students examine the effects of detergents and fertilizers on aquatic life and describe algae. Students define the term eutrophication as the process by which a body of water, such as a pond, lake, stream, or river, has a sudden increase...

Students study the ecology, habitats, geographic range and feeding habits of narwhals. They determine at least three reasons for the decline in the narwhal populations and complete the accompanying worksheets.

Students visit a local park to test the quality of the aquatic environments. They search for sources of pollution and examples of pollution control. Based on their obeservations and experiments, they rate their local environment.

Students are introduced to tree structure and use. They identify their special tree using all senses except sight. Students identify six different internal parts within a cross section of tree trunk (bark, phloem, xylem, cambium,...

Seventh graders conduct year long study of water quality over different seasons using variety of probes, including D.O., pH, conductivity and temperature, that are attached to portable technology. Students select three data points in...

Young scholars investigate the important components for a healthy trout habitat. In this fish habitat lesson, students discuss how the aquarium will simulate a trout's environment in nature. Young scholars complete a trout information...
