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.

This module introduces the concept of biological absorption, storage and distribution of chemicals.

This module provides an intrioduction to acid and base chemistry. The Arrhenius and Bronsted-Lowry concepts of acids and bases are discussed as well as the pH scale and neutralization reactions.

This guide accompanies an educational wallsheet that uses active galaxies as an engagement to teach selected topics in physical science and mathematics from the Fermi Gamma-Ray Space Telescope Web site. Active galaxies have super-massive black holes in their cores, some of which emit jets of particles and light. It features three curriculum enhancement activities, background information, assessment information, student worksheets, extension and transfer activities, and detailed information about the physical science and mathematics content standards that are supported.

This large pop-up book with foldouts contains a 3D model of an active galaxy with jets that pops up out of the center. Active galaxies, a major scientific target for the GLAST mission (renamed Fermi in 2008),contain super-massive black holes at their cores, and sometimes emit jets of particles and light. One foldout contains explanatory information for the parts of the galaxy depicted in the central pop-up, as well as a glossary, while the other contains a classroom activity, the "Tasty Active Galaxy." The back of the book features a cartoon story: "How the Galaxy Got Its Jets."

This site presents information about the Advanced Composition Explorer (ACE) spacecraft and its mission, science goals, history, and background. The mission summary includes a brief description of the energetic particles from the sun and from interstellar and galactic sources that are the objectives of the ACE mission. Links to additional information are also supplied.

Multiple activity, comprehensive lesson plan includes background information, grading rubric, information on associated learning standards and assessment, as well as links to additional external resources. Activity explores the concepts of a hurricane's impact on the environment, society, and economics of a given community. Students map the potential storm surge and flooding on a topographic map and locate and report on past hurricanes in a specific geographical region.

The Mariners' Museum's curriculum guide with teaching activities that address maritime discoveries from ancient times to Captain Cook's 1768 voyage to the South Pacific. One of four online expeditions. Age of Exploration curriculum includes lesson plans, vocabulary, links to related sites, reference material, video, biographies of famous explorers, and more. Lessons include latitude and longitude, creating a compass, an astrolabe, and a globe, identifying the parts of a ship, plus 7 more.

This site has something for everyone, from glaciologists to grade school students. It explores nearly all aspects of glaciers and includes data and science, facts, a gallery, and a glossary.

This comprehensive site is an introduction to sea ice: what it is, how it forms, how it is studied, how it affected historical expedition in the polar regions, and what role it plays in the global climate. The site contains a glossary of sea ice terms and references to additional information, which all serve as an excellent introduction. Data are also available from various collection methods for student interpretation.

This lithograph contains a Hubble Space Telescope image that shows the colorful Planetary Nebula NGC 2440 with one of the hottest known white dwarfs at its center. The text briefly explains the process of stellar death of sun-like stars and those with a mass greater than eight times the Sun. The accompanying classroom activity is a curriculum support tool designed for use as an introductory inquiry activity. It can be incorporated into a unit that has a scientific inquiry and/or stellar evolution theme. During the classroom activity, In Search of... Stellar Death, students use the lithograph images and text to generate questions about the planetary nebula NGC 2440 and how stars end their lives. Students conduct research to answer their questions then compare the endpoints of different mass stars, providing supporting evidence from their research.
