GSA EarthCache - An Introduction. How to Have Fun & Learn about the Earth at EarthCache™ Sites Visiting an EarthCache site is a great way to learn more about our wonderful world.
It can take you to many places that you would not normally visit, and teach you about why those places are special or unique. EarthCache sites can also teach you and your family important skills such as navigation and map reading. What better way to learn than to have fun exploring on this wonderful planet we call Earth! Science Education News: HHMI Debuts EarthViewer App for iPad. EarthViewer shows continental arrangements as they shift through time—including Pangea from 215 million years ago.Have you ever wanted to go back in time to see what the Earth looked like 400 million years ago?
You can with the EarthViewer, a free, interactive app designed for the iPad, that lets users explore the Earth’s history with the touch of a finger by scrolling through 4.5 billion years of geological evolution. The app, developed by HHMI’s BioInteractive team, tracks the planet’s continental shifts, compares changes in climate as far back as the planet’s origin, and explores the Earth’s biodiversity over the last 540 million years. It combines visual analysis with hard data, and helps students make connections between geological and biological change.

Wegener's Puzzling Evidence Exercise (6th Grade) Although Alfred Wegener was not the first to suggest that continents have moved about the Earth, his presentation of carefully compiled evidence for continental drift inspired decades of scientific debate.
Wegener's evidence, in concert with compelling evidence provided by post World War II technology, eventually led to universal acceptance of the theory of Plate Tectonics in the scientific community. The following files are needed for this exercise and can be downloaded in pdf format (Teacher Overview, (For Teachers) Wegener's Key to Continental Positions for grade 6, Student Puzzle Pieces, Key to Wegener's Evidence sheet, and Student Map of the World Today). If students need additional hints beyond those provided below, there is a Puzzle Outline Hint to be used as a base for the puzzle.

Recent images of massive earthquake-induced waves washing away entire towns or buildings reduced to rubble by the violent shaking of Earth’s crustal plates have underlined, all too painfully, the importance of understanding our dynamic and ever-changing Earth.
These natural earthquake hazards will always be with us, but the consequences are not inevitable—if we prepare for them. An essential part of that preparation is education. Education is the key to ensuring that people take appropriate actions when living in earthquakeprone areas and for supporting policies and decisions that will save lives and property. Earthquake Science Explained is a series of short articles for students, teachers, and parents originally published as weekly features in The San Francisco Chronicle.

The applet lists a "halflife" for each radioactive isotope.
What does that mean? The halflife is the amount of time it takes for half of the atoms in a sample to decay. The halflife for a given isotope is always the same ; it doesn't depend on how many atoms you have or on how long they've been sitting around. For example, the applet will tell you that the halflife of beryllium 11 is 13.81 seconds. Let's say you start with, oh, 16 grams of 11Be.
