Earth's Core Hotter Than First Believed

coreUsing a series of very technical tests, scientists from the French research facility CEA have determined that the Earth's core is roughly 6,000 degrees Celsius. That is approximately 1,000 degrees hotter than the temperature obtained by tests in the 1990s.

These new figures show that the center of the Earth is just as hot as the surface of the sun.

The experiment that supplied the new temperature used X-rays to probe tiny samples of iron at extraordinary pressures to examine how the iron crystals form and melt. The BBC reported that "To replicate the enormous pressures at the core boundary - more than a million times the pressure at sea level - they used a device called a diamond anvil cell - essentially a tiny sample held between the points of two precision-machined synthetic diamonds.

Once the team's iron samples were subjected to the high pressures and high temperatures using a laser, the scientists used X-ray beams to carry out "diffraction" - bouncing X-rays off of the nuclei of the iron atoms and watching how the pattern changed as the iron changed from solid to liquid."

Crisis~ the Game

During the last week of school~ I decided to try an experiment. Inspired by a documentary about John Hunter~ the fourth grade teacher who created the World Peace Game~ I began playing a simulation with my gifted fifth graders.

I called it Crisis~ the game.

The reason I called it Crisis was because I wanted my students to become problem solvers~ and what better place to solve problems but in the world.

The rules were simple:

  1. 1. Solve whatever issues or problems...

Desk Olympics

Sometimes~ it feels like a no-win situation.

You position the students desks facing each other~ in cooperative learning style~ and their eyes are on each other~ instead of you.

You face the desks toward you~ and it may discourage discussion and create the feeling of being an institution.

That is~ until you learn about Desk Olympics.

The concept involves training...
