In this activity, students will have the opportunity to witness the fragile nature of organisms with regard to temperature. These organisms include common bacteria, such as Escherichia coli and Pseudomonas aeruginosa. Students will understand the role of temperature in determining what kinds of organisms are found in unforgiving environments. As part of the activity, they will practice aseptic technique ...

Paleontologists occasionally find ancient tracks and footprints preserved in the rocks. This lesson opens the door to analysing those footprints, and gleaning information about body size and activities of the extinct animals that made the tracks. Students will learn that patterns can reveal much about the past, in light of the present; and that bipedalism has appeared several times. Relationships ... Full description.

This slide show discusses plant-rich deposits called middens, that are found in caves and rock shelters in the arid southwestern United States. Middens are an amalgamation of plant and animal remains encased in crystallized packrat urine, and can be used to reconstruct past vegetation and climate in the immediate area of the midden deposit. This slide set outlines past climate variability by reconstructing ... Full description.

Randy Davis is a marine biologist who made a major contribution to the study of Weddell seals in Antarctica. Weddell seals spend about 90 percent of their time submerged, making them a tricky animal to study. Davis developed a special camera to study the seals. This in-depth profile takes a look at Weddell seals in Antarctica and of how scientists monitor them. In the question and answer profile Randy ... Full description.

Using this material, students will discover that under special experimental conditions, fish have been observed functioning in ice-free cold salt water at a temperature of -6 degrees Centigrade. Research has found that these fish have eight types of anti-freeze molecules which bathe the interior surface of their skin, acting as a barrier to ice propagating in from outside. When the anti-freeze molecules ... 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.

In this activity students will become familiar with oceanography terms by writing an oceanography horror story. Terms include sea floor features, marine organisms, oceanographic sampling, and creative writing. Students can use their imaginations to good advantage in this activity, but they must get the facts right! For example, they can change one characteristic of an organism, such as increasing ...
