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."
Online teaching encourages us to think outside the box. It is different than that of a brick-and-mortar where you have your office, and your students stop by to just “visit .”Your colleagues are not next door to run to lunch, and there is no band practicing their marching routines for the big football game. But online learning offers so much, and as lifelong learners, we must show our students that it is just as...

Importance of decorating your classroom - A new school year is beginning.
As teachers, we are lifelong learners that want to be the best we can be. In my opinion, we are always changing and learning, and we want to do what is right for the students we teach. I always tell my students that I am a mentor, guide, cheerleader, and co-learner. As you approach another new course with students that are needing you to give them your all, what will you do to ensure that you are being innovative...
Mindfulness-or training one’s attention to focus on the present moment-has become all the rage, filtering into schools and classrooms. Books and articles suggest that teachers and students can benefit from mindfulness practices such as mindful breathing, meditation, and mindful walking.
While I subscribe to the concept of mindfulness, the term might put off some educators, who don’t want to get up in cultural nuances or esoteric practices. Therefore, let’s use the phrase, conscious...
