This reference list has more than 25 books on biodiversity. For each title, the book's author, publisher, and publication date are given. The diverse list includes broad introductions to biodiversity, insightful looks at evolution and extinction, examinations of the partnership between insects and flowers, portraits of vanishing species and explorations of the factors contributing to a global biodiversity crisis.

This video provides an overview of how computer models work. It explains the process of data assimilation, which is necessary to ensure that models are tied to reality. The video includes a discussion of weather models using the Goddard Earth Observing System (GEOS-5) model and climate models using the MERRA (Modern Era Retrospective Analysis for Research and Applications) technique.

This interactive map allows the user to explore projected alterations of land surfaces in coastal communities, based on different scenarios of sea level changes over time.

This is a multi-step, interactive tool for users to identify potential risks (to people, buildings, infrastructure, contamination, land) for selected coastal areas in the US, using scenarios of water level rising (as a result of tides, sea level rise, and storm surge) from 0-10 feet. Tool provides local, regional and national resources as guidance for managing risk.

Perhaps best known for its role as the antagonist in the film Jaws, the Great White shark is probably the world‰ŰŞs most feared animal, and easily the most fearsome of the sharks. In this video, Jonathan travels to Mexico to meet a Great White up close and personal. Nothing can prepare him for the sheer size and strength of a fully grown Great White shark! He learns how white sharks are being studied and how they react to both people and sea lions. Please see the accompanying study guide for educational objectives and discussion points.

When manatees were first seen by Columbus, he thought they were mermaids..but he had been at sea for a long time! Today these gentle marine mammals are threatened by loss of habitat and collisions with boats. This video segment explores the endangered manatees of Florida and their struggle to survive, as well as some of the people who are working to save them. Please see the accompanying lesson plan for educational objectives, discussion points and classroom activities.

The Take Action column in the free, online magazine Beyond Weather and the Water Cycle suggests actions young people (K-grade 5) can take to reduce the impacts of climate change. The magazine examines the recognized essential principles of climate literacy and the climate sciences as well as the guiding principle for informed climate decisions.

This article describes energy efficiency as it relates to home and school energy use and provides ways that children can help.

This article provides an overview of Tapped In, a web-based learning environment for educators and professional development providers.

This video segment from the Nevada Department of Wildlife looks at tarantulas' survival skills and their habitat.

This article provides an overview of energy education curriculum materials available from the National Energy Education Development (NEED) Project. Teachers may become a member, or use free online resources.

This article provides lesson plans about natural resources and energy sources for elementary teachers.

In this video adapted from Earth Island Institute, meet a high school student who educated her community about how a coal-burning power plant was contributing to asthma and other health problems there.

This interactive map allows students to experiment with decadal average temperature projections. Overall temperatures are expected to rise throughout the century and this tool demonstrates those projected measurements.

This NASA video discusses the impacts of the sun's energy, Earth's reflectance, and greenhouse gases on the Earth System.

This visualization graphically displays temperature and CO2 concentration in the atmosphere as derived from ice core data from 400,000 years ago to 1950. The data originates from UNEP GRID Arendal's graphic library of CO2 levels from Vostok ice core.

This is an interactive website that provides descriptive information and data related to ten key climate indicators. These climate indicators and related resources show global patterns and data that are intuitive and compelling teaching tools.

This investigation is a laboratory activity in which the alkalinity of 2 types of substrates (carbonate vs. non-carbonate) are compared on the basis of titration. Students will reflect on the relationship of alkalinity and toxic heavy metals. Teaching ideas from: Project Wet, Water Education for Teachers as found in: "Healthy Water Healthy People, Field Monitoring Guide "(2003)

This engaging video focuses on national and global wind energy potential by specifically highlighting Texas' role as wind energy leader and energy efficiency efforts in Houston, Texas.

In this activity, students calculate the cost of the energy used to operate a common three-bulb light fixture, and compare the costs and amount of CO2 produced for similar incandescent and compact fluorescent light bulbs.
