Grains of Sand Reveal Possible Fifth State of Matter
“You walk on the beach, and the sand supports your weight. Pick up a handful, and it runs through your fingers, like a liquid. But you can’t walk on water,” said Jaeger. “In the top of an hourglass, sand is this strange solid. It’s at the verge of being a solid; it flows through the middle as something like a liquid, and then it’s a solid again,” he said.

A Film About Our Planet: HOME
HOME is a full-length film by Yann Arthus-Bertrand, being shown on YouTube. The movie shows Earth’s beauty with breathtaking aerial footage, and discusses the impact humans have had on the planet. Below is a short trailer.
You could show parts on several days. Or choose parts to show. Definitely has a theme worthy of showing to an Earth Science class. You decide what your own students can handle. Could even be shown without sound while your students work on an Introduction to Earth Science assignment! (Scroll to the bottom of the page.)

The Formation of Earth's Mantle
"By using a super-computer to virtually squeeze and heat iron-bearing minerals under conditions that would have existed when the Earth crystallized from an ocean of magma to its solid form 4.5 billion years ago, two UC Davis geochemists have produced the first picture of how different isotopes of iron were initially distributed in the solid Earth."

Element #112 added to Periodic Table
Ununbium
Symbol: Uub
Atomic Number: 112
Atomic Mass: (277.0) amu
Melting Point: Unknown
Boiling Point: Unknown
Number of Protons/Electrons: 112
Number of Neutrons: 165
Classification: Transition Metal
Crystal Structure: Unknown
Density @ 293 K: Unknown
Color: Unknown
I consider this pretty BIG NEWS! The element Ununbium has been added to the Periodic Table! What fun!
Ununbium is not its "real" name. Check this site out for keys to the naming of newly discovered and as yet "unnamed" elements. Scientists argue so much over who first "discovered" the heavier elements, so they give them a scientific name so we can call them something. Then they let the scientists duke it out till someone is declared the winner and gets naming rights.
BBC Article about Uub.

Research suggests winds dying down across US
"The wind, a favorite power source of the green energy movement, seems to be dying down across the United States. And the cause, ironically, may be global warming — the very problem wind power seeks to address."

Quatenary Period Wins Out
"Pending an almost certain ratification by the ultimate authority--the International Commission on Stratigraphy --the Quaternary will officially take over the past 2.6 million years of the geologic time scale, when humans took up tools and the world began slipping in and out of the ice ages."

New Report Sets Forth Principles of Earth Science Literacy
Earth's rocks and other materials provide a record of its history. Our solar system formed from a vast cloud of gas and dust 4.6 billion years ago. Earth's crust has two distinct types: continental and oceanic.
These and other concepts are the major ideas of Earth science that all citizens should know, according to a newly released report--Earth Science Literacy Principles: The Big Ideas and Supporting Concepts of Earth Science--funded by the National Science Foundation (NSF)-supported Earth Science Literacy Initiative (ESLI).
