This three part activity has students set up experiments to help them better understand the atmospheric portion of the carbon cycle. From this activity, they will be able to explain the concept of sources and sinks as they relate to carbon dioxide, the use of indicator solution bromothymol blue (BTB) to reveal the presence of carbon dioxide, and the qualitative differences between animal and fossil ...

This lesson will help students understand how wild species cope with changing factors in their environment, such as new predators, fewer available resources, more difficult access to mates, and variable weather. The interaction of all of these factors, coupled with the gradual nature of the changes that result, make evolution a complex subject to study. With these hands-on labs, students delve into ...

This lesson explores various hypotheses concerning the extinction of the woolly mammoth. Students will explore a Web resource that presents various hypotheses about why the woolly mammoth became extinct, with a special focus on an infectious disease as the cause. As part of the lesson, students will read an online article about the extinction of the mammoths, which poses questions and possible answers ... Full description.

This article discusses the different zones of light that exist within the ocean and how the varying degrees of sunlight and total darkness affect what lives in each zone. Specifically, it covers: the photic zone, the only region where plants and organisms that depend on photosynthesis can live; the aphotic zone, where light is too dim for photosynthesis and organisms rely on detritus (bits of decaying ...

This activity explores how water chemistry is altered by the biological processes of phytoplankton (microscopic photosynthetic organisms). Students will discover what some of these water chemistry changes are, and what influences these changes (type of water, exposure to light, etc.). The students will design an activity based on experience gained from the first activity. They will determine the changes ... Full description.

This site presents an account of a research cruise to investigate how the food webs in different oceanic habitats vary. The scientists wanted to see ocean life in its natural environment and conduct experiments that would not be possible in the laboratory. They looked specifically at three types of ocean habitat: the open ocean, the continental shelf, and an upwelling area. The researchers were hoping ... Full description.

This case study addresses the invasion of lionfish, a native to coral reefs in the tropical waters of the South Pacific and Indian Oceans, to the Alantic Ocean off the southeastern United States. The study explains how scientists are using newly collected data and technology to learn how an invasive species like the lionfish affects an ecosystem. Students can learn about the environmental and economic ... Full description.

In this lesson, students will investigate adaptations found in microorganisms living in cold-seep communities in the Gulf of Mexico and whether they might also be seen in microorganisms living on other planetary bodies. As a result, they should be able to explain the process of chemosynthesis, explain the relevance of chemosynthesis to biological communities in the vicinity of cold seeps, and compare ...

In this lesson students investigate benthic communities in the deep Arctic Ocean to determine the factors that influence their compositions. As a result of this activity, students will be able to identify the three realms of the Arctic Ocean and describe the relationships between these realms. They will also be able to describe different species associations in a benthic community, infer probable ... Full description.

This activity can be used as an introduction to the world of aquatic organisms or as an investigation into ways of assessing diversity. Most of the life forms in fresh and salt water are microscopic, or at least small enough to benefit from being magnified for observation. In this activity students use a simple method to collect living microorganisms from natural and/or artificial environments and ... Full description.
