This poster focuses on the topic of space weather. The front gives overview images and the back tells the story of Sun-Earth connections with additional images. It also contains an educational activity. The poster is now out of print. Full description.

This poster depicts the Milky Way galaxy at radio, infrared, optical, x-ray, and gamma-ray wavelengths. Captions describe the Milky Way and what can be learned about the galaxy from measurements made in each segment of the electromagnetic spectrum. Note: the poster is out-of-print, but a PDF can be downloaded at this site. Full description.

An interactive slide show explores the journey of a single snowflake onto and through a glacier. This journey, which can take as much as 30,000 years to complete, shows that the life cycle of a glacier can be more complex than originally perceived. Full description.

This resource gives an impression of how immense our Universe is by employing a method used many times in "Power of 10" films - that is, starting with an image of the Earth and then zooming out towards the furthest visible reaches of our Universe. This is not, however, an exercise in "powers of 10" - on the contrary, the goal is to show astronomical distances without scientific notation. It focuses ... Full description.

This report discusses how natural processes and human activities affect the interactions of ground water and surface water, and the importance of considering ground water and surface water as a single resource. Topics include natural processes of ground- and surface-water interaction; chemical interactions; and the effect of landscapes on these interactions. There is also discussion of the effects ...

Geomorphology from Space is an out of print 1986 NASA publication edited by Nicholas M. Short, Sr. and Robert W. Blair, Jr. designed for use by the remote sensing science and educational communities to study landforms and landscapes. The core of this book is a gallery of space imagery consisting of 237 plates, each treating a geographic region where a particular landform theme is exemplified. Commentary, ... Full description.

This set of introductory materials outlines the basic concepts of groundwater and hydrology. Graphics with accompanying definitions explain basic hydrologic terms such as aquifer, recharge, and discharge. There are also news articles, a reading list, a questionnaire, and a quiz. Full description.

This site features a series of Flash-based animations on several aspects of the San Antonio Water System. Although regional in focus, the topics are broadly applicable. They include: the hydrologic cycle, aquifer structure and function; non-point-source pollution, fresh water distribution, waste water treatment, aquifer storage and recovery and household water conservation. There are also links to ... Full description.

This three-part module covers the major concepts of the chemistry of water, at a level appropriate for late primary and early intermediate learners. Key vocabulary words are defined using examples that are relevant to children's lives. Each part of the module contains an activity or experiment to reinforce the science content that was covered. Full description.

A phase diagram shows the preferred physical states of matter at different temperatures and pressures. This phase diagram shows these states for water. Critical points, triple points, and ice phase processes are defined and illustrated as a function of pressure and temperature. The diagram is accompanied by a set of tables that give detailed thermodynamic data for the triple points and structural/crystallographic ... Full description.
