This resource introduces students to the Dry Valleys of Antarctica, the largest area on the continent that is not covered by ice. Materials include a map and some brief facts about Antarctica and the valleys, such as size, location and physical properties (temperature, precipitation and others), and an online journal in which participants in the Dry Valleys Long-Term Ecological Research (LTER) project discuss what it is like to live and work there. The journal entries include descriptions of some of the organisms that inhabit the extreme environments of the valleys, physical features of the valleys, and the strange mummified bodies of animals such as penguins and seals that have been preserved in the cold, dry climate. There is also a glossary of acronyms used in the project and a set of links to other websites with additional information about the Dry Valleys.

This special feature page from the American Chemical Society (ACS) showcases the up-and-coming field of "green chemistry," that is, the development of chemical products and processes that eliminate or reduce the use and generation of hazardous substances. A list of principles behind green chemistry, a searchable bibliography of green chemistry references, and green chemistry links (including conferences). This page comes from ACS's Green Chemistry Project, a three-year educational project to develop and disseminate green chemistry educational materials for graduate and undergraduate chemistry students.

As the carbon dioxide concentration of our atmosphere increases and our climate warms, the hay fever season seems to be getting longer and more severe. In this case study, students assume the a role of a public relations specialist contracted to communicate the link between climate change and pollen allergies. The activity focuses on the importance of scientific skills to careers outside science, and is most suitable for a lower-level introductory biology, human health, or environmental science course.

ARKive is a collection of photographs, videos, and fact-files illustrating thousands of species of animals, with emphasis on the International Union for Conservation of Nature and Natural Resources (IUCN) Red List of endangered species, and on species found in Britain. For each animal there are approximately 10 minutes of video footage, 6-10 still photos, and sound recordings (where appropriate), creating a complete profile of the species' characteristic behavior and appearance. The images are accompanied by a page of facts, including taxonomy, a physical description, conservation status, geographic range, habitat, and other information. There are also links to other animals with related taxonomic families, habitats, or conservation status.

In this video adapted from ATETV, learn how Bristol Community College promotes internships and co-ops to prepare students for work in technology-related careers.

This organization promotes sustainable agriculture. Their website provides publications on production practices, alternative crop and livestock enterprises, innovative marketing, and organic certification, and highlights of local, regional, USDA and other federal sustainable ag activities.

In this activity (page 11 of the PDF), learners investigate how quickly water moves through various materials. They measure and compare the permeability of gravel, sand, and soil. Although this was created as a post-visit activity for a workshop about earth processes, it also makes an excellent stand alone activity.

This two-day lesson helps students understand abiotic and biotic factors. Once the concept has been grasped, they can trace the interactions of these factors within a system.

The COSEE network promotes a better understanding of the key role the ocean plays in global environmental cycles and processes. COSEE activities highlight the contributions ocean-science researchers make to scientific knowledge in these important areas. Each COSEE represents one or more ocean science research institution, an informal science education organization, and at least one affiliate organization representing the formal education community.

Children learn how seasonal weather changes affect everything, from the behavior of animals to the way we dress and play.

This learning activity from the Advanced Technology Environmental and Energy Center (ATEEC) provides students with the opportunity to use analytical meters and instruments and perform acid deposition sampling. Students will collect samples from various sources over a period of time, then measure pH and develop graphs or charts. Users must download this resource for viewing, which requires a free log-in. There is no cost to download the item.

Add acidity to a healthy lake and see what happens to the plants and animals in this interactive activity adapted from EcoKids. ***Access to Teacher's Domain content now requires free login to PBS Learning Media.

In this video, an environmental technologist visits an abandoned coal mine in Kentucky to talk about how a remediation system (a series of settling ponds and treatment cells) is neutralizing the acid drainage flowing from the mine and keeping it from damaging a creek downstream.

For years, our oceans have been hard at work absorbing the carbon dioxide that humans create through burning fossil fuels. Find out what effect that extra CO2 is having on our seas.

In this outdoor game, learners play the roles of gray or red squirrels gathering and storing a supply of food in "fall" and recovering enough of them to survive the "winter." Learners carry bags representing their cheek pouches for carrying food. Learners investigate the advantages and disadvantages of how these two kinds of squirrels store food differently.

There are many websites dedicated to providing the public with information about the biological sciences, but ActionBioScience.org may be one of the best around. Started in 2000 by a group of concerned scientists and educators, the site provides articles by scientists, science educators and students on issues related to seven primary areas, including genomics, biotechnology, evolution, and biodiversity. All of the pieces on the site go through a peer-review process and are written with a keen eye towards providing information in a way that is largely jargon-free and highly accessible. From the homepage, visitors can look for articles in one of seven thematic areas, look for materials in Spanish, and peruse materials created just for educators. The site can also be browsed topically in the larger categories of Biodiversity, Environment, Genomics, Biotechnology, Evolution, and New Frontiers or from the "topic directory" which alphabetically lists all the bioscience subjects covered on the site.
