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."

As a teacher, have you ever expected students to listen to you just because you’re the teacher? They’re supposed to listen to the teacher, you think. Or maybe you expect them to pay attention because you know your content so well. You have a master’s degree in math or science instruction. You might have noticed that certain students listen and behave better for you after you began to know them better. You invited them to lunch, praised them in class then they...
