Potential Effects of Amazon Deforestation on Tropical Climate
11.03.2007    

This report describes the results of a study in which climate modeling was used to examine the effects of deforestation in the Amazon basin. The study concluded that changes in land surface properties (loss of forest cover) cause changes in the mean surface wind stress in the tropical Pacific, which in turn results in increased variability of El Nino/Southern Oscillation (ENSO) events.

Under the Weather: Climate, Ecosystems, and Infectious Disease
10.31.2007    

This scientific report addresses questions on climate change and public health. Can we use climate and weather forecasts to predict infectious disease outbreaks? Can the field of public health advance from "surveillance and response" to "prediction and prevention?" Can we predict how global warming will affect the emergence and transmission of infectious disease agents around the world? Under the Weather evaluates our current understanding of the linkages among climate, ecosystems, and infectious disease; it then goes a step further and outlines the research needed to improve our understanding of these linkages.

Dead Zones: Why are the Waters Dying?
10.28.2007    

This lesson explores the effects of pollution, in particular nitrogen pollution, on marine ecosystems. Students can brainstorm the effects of pollution on marine life, examine the sources and causes of nitrogen pollution, discuss possible solutions, and apply their knowledge to specific actions in their own lives.

Ocean Currents - Animated Lesson
10.27.2007    

This animated lesson focuses on ocean currents. Some of the topics covered include: gravity- and wind-driven currents, the Coriolis Effect, El Nino, longshore currents, upwelling, and the global conveyor belt. Additional links to the global impact of ocean currents (video), El Nino (activity), and currents and marine life (activity) are available.

It's Just a Phase: Water as a Solid, Liquid, and Gas
10.26.2007    

In this activity, students will construct models of water molecules in the three physical states. By completing this activity, students will understand that matter can be found in three forms or phases (solid, liquid, and gas) and they will be able to explain the molecular behavior of ice, water, and water vapor.

Carbon Stabilization Wedge Game

Global carbon dioxide

The Carbon Stabilization Wedge game, a unique, hands-on learning tool, helps students learn the impacts of different strategies for reducing greenhouse gases. To emphasize the need for early action, this activity strives to drive home the scale of the carbon mitigation challenge and the tradeoffs involved in planning climate policy. It uses the the concept of 'stabilization wedges' - 25 billion ton "wedges" that need to be cut out of predicted future carbon emissions in the next 50 years to avoid a doubling of atmospheric carbon dioxide over pre-industrial levels.

Communicating and Learning About Global Climate Change
10.23.2007    

This is a 12-minute video on climate change made by the American Academy for the Advancement of Science (AAAS), which can be viewed online as RealVideo or Windows Media. Some of the nation's top climate experts are featured in this video detailing the latest science on the subject and working with the audience to explore inventive educational and technological responses to it.

Communicating and Learning About Global Climate Change (Teacher Guide)
10.23.2007    

This teacher guide created by AAAS is designed to give you a brief overview of Project 2061's recommendations for the relevant ideas and skills that all students should learn to understand the science of climate change, the process of scientific inquiry, and the trade-offs and constraints implicit in making choices about technology.

Our Super Star
10.10.2007    

In this lesson, students use observations, activities, and videos to learn basic facts about the Sun. For example, students will understand that the Sun is a star and that its radiation provides Earth with heat and light. Students also model the mechanics of day and night and use solar energy to make a tasty treat.

Diffusion at Work: An Interactive Simulation
09.15.2007    

This hands-on Oceanography article describes an activity that helps students better understand the nonintuitive concept of diffusion and introduces them to a variety of diffusion-related processes in the ocean. As part of this activity, students also practice data collection and statistical analysis (e.g., average, variance, and probability distribution functions).

Getting to the Core of Climate Change
06.28.2007    

How can we use ice core data from the polar regions to investigate changes in Earth's climate past, present, and future? Students investigate climate changes going back thousands of years by graphing and analyzing ice core data from Greenland and Antarctica.

The Water Cycle
06.28.2007    

In this lesson, students build upon their previous investigations of water and its different forms by learning about the water cycle. Students begin by reviewing previous knowledge about water and how it can freeze or turn into a gas depending on how low or high temperatures become. They then learn about the water cycle and its key processes that affect our lands, oceans, and atmosphere. The ongoing need for fresh-water conservation is also highlighted.

Thermal Expansion and Sea Level Rise
06.28.2007    

Students will use a lab activity to describe the change in water level when the water is exposed to heat, differentiate between thermal expansion and melting snow and ice fields as they relate to sea level rise, and predict the impact of rising sea level on coastal areas.

Make Convection Currents!
06.28.2007    

Students observe convection in water due to temperature differences and describe the pattern of water movement with words and pictures. During a class discussion students learn that the same process happens in both the oceans and the atmosphere.

Exploring the Environment - Severe Weather: Hurricanes!
01.17.2007    

Exploring the Environment™ (ETE) is a series of interdisciplinary, problem-based learning (PBL) modules for high school students. The project engages student teams in addressing real-world problems related to weather, population growth, biodiversity, land use patterns, volcanoes, water pollution, and global warming. Teams analyze remotely-sensed satellite images to come up with solutions to open-ended earth science problems--problems that real scientists are working on today in much the same fashion. In this module, students are asked to track and predict landfall of the next hurricane to threaten the United States.
