This article provides an overview of icebergs' formation and characteristics and the hazards associated with icebergs.

The extreme challenges of life in the polar regions require the animals who make their habitat there to make many adaptations. This unit explores the polar climate and how animals like reindeer, polar bears, penguins, sea life and even humans manage to survive there. It looks at the adaptations to physiological proceses, the environmental effects on diet, activity and fecundity, and contrasts the strategies of aquatic and land-based animals in surviving in this extreme habitat. This unit builds on and develops ideas from two other 'Animals at the extreme' units: The desert environment (S324_1) and Hibernation and torpor (S324_2).

This article lists common misconceptions about weather, climate change, and the polar regions. It provides formative assessment probes and information about teaching for conceptual change.

This nonfiction article, written for students in grades 4-5, explores the life and seasonal migration of the sanderling bird. Modified versions are available for students in younger grades.

Fundamentals of Biology focuses on the basic principles of biochemistry, molecular biology, genetics, and recombinant DNA. These principles are necessary to understanding the basic mechanisms of life and anchor the biological knowledge that is required to understand many of the challenges in everyday life, from human health and disease to loss of biodiversity and environmental quality.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Glaciers and ice sheets may seem dead and empty to the naked eye, but the dust that coats them, cryoconite, is a hotspot for microbes and microbe-driven biogeochemical cycling. However, little is known about the geographical diversity in cryoconite microbial communities. Most cryoconite research focuses on polar microbial communities, and reports on Asia’s high mountain glaciers are rare. A recent metagenomics study found key metabolic and light harvesting differences between polar and Asian alpine cryoconite microbiota. The Asian cryoconite community had more abundant genes for denitrification, suggesting that denitrification is enhanced there compared to polar regions. While Asian cryoconite is dominated by multiple cyanobacterial lineages that possess phycoerythrin, a green-light harvesting protein, polar cryoconite is dominated by a single cyanobacterial species (_Phormidesmis priestleyi_) that lacks phycoerythrin..."

The rest of the transcript, along with a link to the research itself, is available on the resource itself.

This activity is an easy way to demonstrate the fundamental properties of polar and non-polar molecules (such as water and oil), how they interact, and the affect surfactants (such as soap) have on their interactions. Students see the behavior of oil and water when placed together, and the importance soap (a surfactant) plays in the mixing of oil and water which is why soap is used every day to clean greasy objects, such as hands and dishes. This activity is recommended for all levels of student, grades 3-12, as it can easily be scaled to meet any desired level of difficulty.

This article is about the latest remake of Jules Verne's popular 144-year-old novel Journey to the Center of the Earth that also provides links to the American Geologic Institute's (AIG) Educator Guide for using the movie (Journey to the Center of the Earth 3D) to interest students in geology and earth science.

This article highlights seven science lessons that teach elementary students about seasonal change. Suggestions for integrating literacy and science include two lessons that use informational text and cause and effect relationships.

This article sets an historic context for Jules Verne's novel Captain Hatteras (1866), and presents an overview of day-to-day survival on the typical 19th century arctic voyage portrayed in this fictional account.

This nonfiction article, written for students in grades 4-5, explores lichens: a partnership between an alga and a fungus. Modified versions are available for students in younger grades.

This article discusses the types of plants found in the Arctic and Antarctic as well as the adaptations that enable their survival in the polar regions' harsh conditions.

This article highlights science lessons about mammals, mammal diversity and adaptations, and polar mammals. Literacy integrations and alignment to national standards are included.

Students learn about the basics of molecules and how they interact with each other. They learn about the idea of polar and non-polar molecules and how they act with other fluids and surfaces. Students acquire a conceptual understanding of surfactant molecules and how they work on a molecular level. They also learn of the importance of surfactants, such as soaps, and their use in everyday life. Through associated activities, students explore how surfactant molecules are able to bring together two substances that typically do not mix, such as oil and water. This lesson and its associated activities are easily scalable for grades 3-12.

This nonfiction article, written for students in grades 4-5, explores the relationships between various tundra species: marsh marigolds, bot flies, and caribou. Modified versions are available for students in younger grades.

This article discusses the strategy of using discrepant events in elementary science instruction. It includes links to four video clips of the sun's path in the Arctic or Antarctica.

Abstract: This video explores individual variation found among Weddell seals, and what those differences might mean for the future of this southernmost mammal on Earth, living in the most pristine marine environment remaining on our planet. The video features interviews on location in the Erebus Bay area of Antarctica's Ross Sea with ecologists Jay Rotella, Bob Garrott, Thierry Chambert, and Jesse DeVoe of the Weddell seal population project research team. Also featured is some truly spectacular underwater footage by Henry Kaiser, courtesy of Jo-Ann Mellish and Project B-470 (NMFS Permit No. 15478 and ACA 2003-12), and lots of Weddell puppies and moms filmed by Mary Lynn Price and other members of the B-009 Weddell research team. The video was edited and produced by Mary Lynn Price. This project video is made possible with funding and support from the National Science Foundation, and the assistance of the United States Antarctic Program. Produced in association with Montana State University.
