Users can learn about the need for more efficient usage of water for irrigation, and about the activities of the Water Resources Development and Management Service, which is concerned with sustainable use and conservation of water in agriculture. Links to other sites related to irrigation practices and ... Full description.

In this lesson, students learn about the limitations of weather forecasting and how consumer-driven weather forecasting companies attempt to meet the demand for accurate, long-term weather forecasting. The students then act as meteorologists, researching the weather patterns occurring in specific regions of the world and developing their own weather forecasts. Objectives, a materials list, procedures, ... Full description.

NeMO studies the dynamic interactions between submarine volcanic activity and seafloor hotsprings at an observatory called Axial Seamount. The research activities at NeMO provide an extraordinary educational opportunity, both from the daily reports from expeditions at sea and from creative learning materials based on NeMO results. The site features curriculum materials designed for high school and ... Full description.

This Internet-based collaborative project will allow students to share information about water usage with other students from around the country and the world. Based on data collected by their household members and their classmates, students will determine the average amount of water used by one person in a day. They will compare this to the average amount of water used per person per day in other ... Full description.

This activity explores the potential impact of climate variability and change on one of Earth's increasingly vulnerable resources, forests. Although the activity is designed to tap specific skills and knowledge through scientific inquiry, its broader intent is to stimulate thought about the long-term impacts of a warmer planet. The scenario invites students to examine higher level issues of climate ... Full description.

For this lesson, students will assume the role of an outdoor sports event planner. They will evaluate changes in air quality over a one year time frame based on a review of Air Quality-Carbon Monoxide Data and quantitative line graphs. The data will be used to make an informed decision about the best times of the year to plan for outdoor and indoor sports activities. Full description.

In this lesson, students will investigate changes in air quality due to human interaction particularly burning of fossil fuels, and crop burning which increase levels of carbon monoxide. Students will evaluate changes in air quality over a 6 month time frame using Air Quality-Carbon Monoxide Data and draw conclusions based on observing color plot comparison graphs. Full description.

In this lesson,students will play the role of a sailboat captain in The Hamptons, an upscale vacation venue, who must schedule sailing trips to amuse tourists and make money for the company. Using Monthly Wind Speed data from 1995-2005 from MyNASAData website, students will evaluate changes in the monthly wind speed, draw conclusions about how wind speed will effect their company positively or negatively, ... Full description.

This lesson will connect the idea of the tilt and orbit of the earth (changing of seasons) with monthly changes in snow/ice. Students will evaluate changes in the snow/ice cover from January 2008 to June 2008 and compare to the tilt of the Earth and position in orbit (seasonal change) using monthly Snow/Ice Data from January 2008 to June 2008 from MyNASAData website. Full description.

In this lesson,students will evaluate a location in the Northern Hemisphere and Southern Hemisphere to determine the areas best for collecting solar power. Changes in surface radiation will be evaluated using Monthly Surface Radiation data from 2007 from MyNASAData website. Students will draw conclusions about how surface radiation levels will affect choice of solar power plant location selection ... Full description.
