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."

It’s no secret that students, especially those in elementary schools, have trouble sitting at a desk or in front of a screen all day.

It’s natural for children to want to move, jump around, burn off some of their extra, seemingly boundless energy. It’s also apparent that children (and adults) are more distracted than ever. We all need tools to help us focus.  

Movement is good—but researchers are finding that movement coupled with mindful intention, for instance, becoming...

A Major Weakness in Our Education...

Students can spend 12 years in school (even more) and not know what they’re good at.

While they have hopefully mastered academics such as reading, math, and science, they likely have spent little to no time studying their own natural talents and strengths during that time. This is a major gap in our education system.

There has been a plethora of research on the development of individual strengths and talents and their use in the workplace, mainly by Gallup. The company had...

Staying Positive in This Unknown Time:...

As families and teachers, we are all concerned about how our children are dealing with what is happening in the world. Staying positive during this unknown time is such an essential part of how your children will learn to deal with times of uncertainty and conflict.
