This is the home site for the online series of Exploring the Environment (ETE). Exploring The Environment features an integrated approach to environmental earth science through modules and activities. The vision of the ETE online series is to promote science-literate and reflective students who are knowledgeable of the earth's processes and their responsibilities for stewardship. The modules and activities ... Full description.

The Earth Science Picture of the Day is an image archive that is hosted by the Universities Space Research Association in association with NASA's Goddard Space Flight Center with a record of entries beginning September 2000. Each image is accompanied by a descriptive text and links to relevant supporting websites. Keyword searching is provided. Browsing by related fields includes: agriculture, astronomy, ...

The purpose of NASA's Earth Observatory is to provide a freely accessible publication on the Internet where the public can obtain new satellite imagery and scientific information about our home planet. The focus is on Earth's climate and environmental change. The site is divided into six main sections: Data and Images, Features, News, Reference, Missions, and Experiments. The Data and Images, Features, ... Full description.

This website complements the book "Dr. Art's Guide to Planet Earth" written by Dr. Art Sussman. The website includes animations, lesson plans and experiments that can be used in conjunction with the book. The number of items are continually being increased as a result of collaboration with K-12 teachers and field testing. It also includes the complete text of the first chapter which introduces systems ... Full description.

This site contains 12 questions on the topic of the atmosphere, which covers electromagnetic radiation and layers of the Earth's atmosphere (exosphere, thermosphere, and more). This is part of the Principles of Earth Science course at the University of South Dakota. Users submit an answer and are provided immediate verification. Full description.

This applet determines the height of the base of any cumulus cloud that might form due to convection, when the temperature and dew point sliders are adjusted. The applet displays clouds between 1000 and 10,000 feet. Full description.

This lesson demonstrates the relative thickness of the atmospheric layer that includes the troposphere and stratosphere. Students will be able to explain how relatively thin the atmosphere is compared to the size of the planet and will understand the relative extent of the four major atmospheric layers. The instructor guide contains detailed background material, learning goals, alignment to national ... Full description.

This activity is designed to teach students how to read and understand a meteogram. It should enable students to more readily understand the movements of fronts and the interactions of weather variables as illustrated by the meteogram. Generally students measure and observe the variables as separate entities but by viewing the weather variables including temperature, dew point, wind speed, wind direction, ... Full description.

This activity is designed to be used as either a teacher demonstration or a laboratory activity as part of a weather unit. It reinforces the concepts of condensation, dew point, humidity, pressure, condensation nuclei, and the process of cloud formation. The site has a list of required materials, detailed instructions, questions for the students, and links to other weather-related sites. Full description.

In this lesson, students learn how meteorologists measure the weather by examining some online, real-time data resources and collaborating to create an in-class weather station that tracks local weather patterns for one week. Students compare this information to weather patterns in two other locations. After completing this lesson, students should be able to explain ways that meteorologists measure ... Full description.
