This poster outlines the major mission highlights of the Interstellar Boundary Explorer (IBEX) mission, a Small Explorer Earth-orbiting spacecraft that is designed to map the distant boundary between the solar wind from our Sun and the interstellar medium. This poster supports a full length planetarium show about the IBEX mission and the boundary of the Solar System. Each short activity/product helps ... Full description.

Imagine the Universe is dedicated to discussion about the universe, how it is evolving, and the kinds of objects and phenomena it contains. The site is intended for students age 14 and up and is a service of NASA's High-Energy Astrophysics Science Archive Research Center (HEASARC). Contained within this site are explanations of the concepts and principles used to study and understand the universe, ... Full description.

This activity and demonstration teaches the concept of parallax (the apparent movement of an object caused by a change in the viewer's position) and relates the concept to a real-world astronomical event, ­the discovery of Pluto. It employs the Blink Comparator, an online simulation illustrating the technique used by Clyde Tombaugh to discover the ninth planet on February 18, 1930. Full description.

In this lesson, students observe a teacher-directed demonstration that provides a conceptual understanding of latent heat, the "hidden heat" present in all changes from one phase to another, by using a hand warmer. Full description.

Watersheds are those land areas that catch rain or snow and drain to specific marshes, streams, rivers, lakes, or to ground water. This site allows users to locate their watershed by city, county, state, or region. Links provide information about stream flow, water use, conservation efforts, demographics, forest riparian habitats, science in your watershed, water discharges, and assessment of watershed ...

This poster outlines the components of our Solar System?s heliosphere, with a compelling heliosphere boundary image on the front and introductory information about the parts of the heliosphere boundary on the back. This poster will be distributed along with activities (some of which are included in this review cycle) to support a full-length planetarium show about the IBEX mission and the boundary ... Full description.

This activity relates an elastic collision to the change in a satellite?s or spacecraft?s speed and direction resulting from a planetary fly-by, often called a ?gravity assist? maneuver. Both hands-on and online interactive methods are used to explore these topics. Full description.

The Supernova Educator?s Guide was developed by the XMM-Newton and GLAST E/PO programs. It features three curriculum enhancement activities and one scientific literacy activity, extensive background information, assessment rubrics, student worksheets, extension and transfer activities, and detailed information about the physical science and mathematics content standards. An electronic version of one ... Full description.

This site describes snow crystals and snowflakes. Although a common meteorological phenomenon, snow crystal growth is a fascinating and poorly understood process, in which remarkably complex and beautifully symmetric structures appear, quite literally, out of thin air. The many facets of snow crystals are described here, along with the attempts to understand their formation. Site highlights include ... Full description.

This site provides the user an opportunity to explore storm clouds and climate change through the use of NASA climate research data obtained through satellite imaging. The user is challenged to investigate actual scientific research data on clouds and storms, and make observations and interpretations available to NASA research scientists for review. Topics addressed by these investigations include ... Full description.
