25 Things You Can Do To Save Coral Reefs
"In the United States, the Department of Commerce’s National Oceanic and Atmospheric Administration (NOAA) is responsible for monitoring and maintaining the health of domestic coral reefs. But all of us can help, even if we don’t live near a coral reef. To that end, NOAA offers twenty-five reef-saving activities (""Become a member of your local aquarium or zoo."") that will spur your own reef conservation ideas."

"PBS: Mountain Maker, Earth Shaker"
"Take a hard-boiled egg and crack its shell. Does the egg remind you of anything? The Earth,perhaps? The egg could be seen as a tiny model of the Earth. The thin shell represents the Earth’scrust, divided into plates; within the shell is the firm but slippery mantle. Visit this PBS ScienceOdyssey (my pick of the day) for the Shockwave Plate Tectonics activity illustrating whathappens when Earth’s plates push and pull against each other. Next browse the thirteen relatedarticles, also available in printable versions with white backgrounds."

"Fossils, Rocks and Time"
"Reproduced from a free print publication of the U.S. Geological Survey, this online booklet is a marvelous introduction (in non-technical language) to how geologists study fossils to learn about the earth’s history. ""People who study Earth’s history also use a type of calendar, called the geologic time scale. It looks very different from the familiar calendar. In some ways, it is more like a book, and the rocks are its pages. Some of the pages are torn or missing, and the pages are not numbered, but geology gives us the tools to help us read this book."""
