THE MOON & MOON PHASES

• Demonstration of Moon Phases (Java) - moon phases from three points of view: top view; earth view; or both. Great tool for visualizing what causes the cycle of moon phases.
• Moonlight Madness - Learn to identify moon phases (GIF animation by Ed Stephans stephan@henson.cc.wwu.edu)
• Earth and Moon Viewer. Real-time views of the earth showing day and night views. Also views of the earth from the sun and moon.
• Sky & Telescope's Touring the Moon with Binoculars

  • For a unique perspective of the 26 February 1998 solar eclipse (looking down at the Earth instead of up at the Sun), a variety of interesting eclipse images are available from the GOES Project Eclipse Watch Web site, including a small GIF animation (0.2 MBytes) and a medium QuickTime animation (0.6 MBytes) which are ideal for use in the classroom.

OCEAN TIDES

Did you know that ocean tides are caused by the moon? See if you can determine the relationship between the phase of the moon and the time of high (or low) tide and tidal range (difference between high and low tide) by visiting either the WWW Tide and Current Predictor (or the WWW Tide and Current Predictor mirror site) or the NOAA Coastal and Estuarine Oceanography Branch (CEOB) Tide and Tidal Current Prediction. See also the NOAA National Ocean Service Tide and Current Glossary.

• Terrestrial Impact Craters - Impact craters are geologic structures formed when a large meteoroid, asteroid or comet smashes into a planet or a satellite. Believe it or not, the Earth has been even more heavily impacted than the Moon! In contrast to the moon (where craters are well-preserved), craters on the Earth are continually erased by erosion and redeposition as well as by volcanic resurfacing and tectonic activity. Thus only about 120 terrestrial impact craters have been recognized. View several of the more prominent craters on Earth.
