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...

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...

Sometimes a little pressure isn't a bad thing! A collaborative lesson uses models to demonstrate how air pressure inflates and deflates the lungs. Participants use everyday materials to create models of the chest cavity to simulate how a...

Life before the dinosaurs was pretty amazing—and very fragile! Discover what Earth was like for Cambrian creatures, from the smallest ocean-dwellers to the first land animals. A video from an extensive biology playlist explores how early...

Has Earth's atmosphere always been capable of supporting life? Discover how the air around us has evolved in the first video in a series of seven. Learners watch the amazing transformations that occurred within the atmosphere and the...

Dangerous detergents? Who knew? Pupils learn of the darker side of laundry day as they complete the series of seven videos on water and the environment. The video shows common detergent ingredients, how these ingredients can harm the...

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...

When at rest, humans exhale about 17.5 ml of water per hour, but they lose about four times that amount during exercise. The video shows learners how worms, insects, fish and humans all respire very differently. Viewers then explore the...

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.

Trying to plan a lesson on the respiratory system? Then take a deep breath, because this presentation has you covered. From the atmosphere through the lungs and blood to the body's cells, this presentation investigates the complex series...

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...

young scholars 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...

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...

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...

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...

In this oxygen activity, students analyze date about the oxygen levels in a river to determine the cause of the dying fish. This activity has 2 graphs, 12 short answer questions, and 2 graphic organizers.

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...

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...

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.

In this watershed worksheet, students read through related definitions and complete 17 short answer questions about deposition and erosion in the Hudson River.

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 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...

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...
