Using 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."
Infants and toddlers are unique in their own way as they begin developing, growing, and learning—and it is no different for language development. Infants begin learning in the womb and can differentiate the family’s voices almost immediately. In the second half of the first year, they are able to differentiate foreign languages and sounds from the language they will be using (Klass, 2017). Language development is...

Hello to the 2023-2024 school year! It is here!
Let’s make this your best school year yet! As this year begins, think of new ways to involve your families in the classroom and new ways to communicate and reach all people. Whether parents are separated, grandparents, or other family members are raising children; everyone needs to be involved in a child’s school success. Maybe...
There is a Black History Month, Native Americans Heritage Month, a Hispanic American Month and a Woman’s History Month. Asian American and Pacific Islanders Heritage Month is a time to highlight the contributions of these groups of people to the culture of the...
I had been retired for about 18 months and not enjoying myself. My wife would travel to go to work and leave me alone with a TV and my two dogs. This was certainly not how I wanted to spend my “golden years”. After working over 51 years in education in the United States and Egypt I had few plans on how best spend my idle hours. Frankly, I was bored and frustrated.
Fortunately very close to my house they were building a new school. I decided to look into this possible opportunity....
