Water on Mars is a Windows to the Universe Exploratour and provides information and images about Mars' atmosphere, polar caps, Martian fog, clouds, Martian storms, possible rain, running water, outflow channels, river valley networks, tributaries, map of valleys and networks, lakes and floods, possible shorelines, Mars Pathfinder, Martian rocks, Mars cryosphere, and the water cycle. Windows to the ... Full description.

This Windows to the Universe site provides beginner, intermediate and advanced information about Martian flooding. It includes a NASA image of Mars despicting outflow channels and river valley networks, which provide evidence for two theories about the global Martian water cycle. Full description.

This module from the Mars Exploration Curriculum revolves around the question of whether there is water on Mars. By experimenting with water as it changes state and investigating some effects of air pressure on water's boiling temperature, students not only learn core ideas in physical science but can deduce the water situation on Mars by applying those concepts. They use evidence from their work ... Full description.

This series of modules integrates printable images of Mars into classroom activities. Four broad topics cover the exploration of Mars and the Pathfinder missions, the great Martian floods and the Pathfinder landing site, the canyon Valles Marineris, and water on Mars. Each topic has several discrete activities associated with it that can be used independently. There are supporting materials for teachers ... Full description.

This article examines the evidence for recent liquid water on Mars. NASA scientists believe that piles of crater-topped debris snapped by the Mars orbiter were caused by the teakettle explosion of water through volcanic lava flows at the planet's equator and are the best evidence yet for recent liquid water at the Red Planet. Researchers believe that lava flows advanced over wet ground, causing steam ... Full description.

In this lesson students explore the idea of water on Mars. Many active links allow the students to come to their own conclusions about water on Mars and explore how Earth might appear from space without water. Other links provide the students with the opinions of experts. This is the eighth in a series of interactive student lessons from the Martian Sun Times. Full description.

This collection includes QuickTime, MPEG-1, and GIF animations and interactive images of Martian exploration and geology. These visualizations illustrate Mars' surface geology and historical and current water presence and display information from the Spirit, Opportunity, Pathfinder, and Sojourner rovers and landers. Many of the visualizations have long download times, but are well worth your patience. ... Full description.

This Nine Planets page contains details about the planet Mars. Information includes planet diameter, mass, distance from the Sun, orbit, and mythology. Also covered are planet composition, surface features, atmosphere and magnetic field data, temperature on the planet, and results from exploration spacecraft. Phobos and Deimos (Mars satellites) are also covered in depth. The site provides links to ... Full description.

This article is a Why Files report on the increase in "natural" disasters from floods, probably the most destructive type of natural disaster. The article notes that in constant dollars, the cost in 1998 alone exceeded the economic toll of the entire decade of the 1980s. Evidence is cited that inundations reflect human action rather than simply rainfall amounts. The report covers: furious floods (including ... Full description.

This NASA-hosted site is a section of the Mars Pathfinder Science Results Directory with a specific emphasis on the geologic and geomorphic characteristics observed. Many photos and satellite images are available, with the option to view and download full size images. Scientific theories are offered as to the probable geomorphic agents sculpting Mars' surface.
