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."

A New Year’s Resolution: Include Gifted...

During 2018, why not resolve to reach all learners in the classroom, despite where they fall in terms of academic ability?

Included in that resolution might be the goal to further challenge gifted students—a promise to help them learn something new everyday day, to provide enrichment and opportunities to develop their abilities, and not simply ask them to do more work or tutor classmates.

If you’re already challenging the gifted, I congratulate you! But you still might find...

If I had a Magic Wand (and Could Change...

I often dream about what I would change in education if I could wave a magic wand. I try to work towards those changes in the real world--but dreaming, I guess, is easier.

I think imagining how we might better serve students is an important first step. Closing our eyes and asking ourselves: What kind of education would I like to see for students and my own children? Then, letting the answers emerge.

Here are some of my “answers” (in no particular order):

Tackling the Narrative of Your Grant...

I promised to follow up my last blog about demographics with a start to the process of writing your narrative. This is the heart and soul of your application.

Before you start, read the rules or application forms you have received from potential funding sources you've identified. Read them twice. With a federal grant, read them four times. You want to know about formatting, spacing, font (sometimes), number of pages, etc. You'll want to know if you can include an appendix beyond the...

Demographics in Grant Applications

Okay, there's no way around it, there are parts of the grant application process that are just plain boring. Last time, I finished a discussion about federal and state grants with a promise to discuss the narrative writing process for prospective grant seekers. Grant writers probably develop writer's block more often than any other writing niche, so it helps to have it all compartmentalized and routine. In our resources section, you'll find a sample of a "demographics" page for a grant...

With this being the time of year for the story, A Christmas Carol, it's a great opportunity to learn about its author, Charles Dickens. One of the most famous writers of all times, Dickens also wrote Oliver Twist, Great Expectations, A Tale of Two Cities, David Copperfield and more. 

Today, a person who is very tight with money, is often called a scrooge, after, the main character in A Christmas Carol. Did you know that several other words and phrases were coined by Charles...
