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."

The Samurai were fierce warriors of Feudal Japan (we’re talking 1100 to 1800s). They lived during times of constant fighting, whether between warring lords in Japan or against invading enemies, such as the Mongols.

Samurai had to be incredibly sharp, focused, centered, calm, and ready to leap into action at any moment. This explains why they were drawn to the practice of Zen Buddhism and training the mind through meditation.

Today, the enemy or constant threat isn’t so much...

Educators - Do your homework!

I have recently retired as a school administrator after 51 plus in education.  I have been reading about a lot of new administrators who are all ready burning out, feel overwhelmed, overworked, and under compensated.  I was fortunate to have worked in more than a dozen schools and similar number of other educational positions. I worked in seven states and two countries. My point in saying this as I changed jobs, I had to thoroughly investigate each one before accepting the new assignment. ...

How you feel depends on your role—whether you're a first-year teacher, a veteran teacher, or maybe it's your last year; a new student in a district; a graduating senior; or a parent dropping your child off for the first time. Returning to school means...

Family Forums: What are They?

As you begin your new school year, I wanted to share with you something that I did to involve, engaging and build relationships with families----I call them “Family Forums”.  I decided that Family Forums would not only become a normal part of building a successful reciprocal relationship with the families in my classroom but also a time to teach and learn from one another. My forums were a party for my families, not a meeting but a place to come and have fellowship with others. It was also a...

Ten Ways to Engage All Students

As we begin the new school year, stop and reflect on what new things you want to try. Ask yourself how you can make your lessons more engaging or hands-on. Do you need to try new ways of differentiation? What about researching engaging ideas online or observing colleagues? Is there a professional development you have been wanting to attend?

At the beginning of each new year and after each teaching day, I...

Welcome Back to School! Freeing...

It is the most exciting time of the year as teachers start returning back to school. Teachers and administrators are looking forward to the new school year. Many administrators think that this is a time for team building and professional development in the short time before students  arrive. As a former principal, I learned that teachers are anxious to get into their classrooms and prepare for school to start.

What I was told was that our teachers appreciated how I approached the...
