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."
Summer learning has a huge impact on accelerating your child’s success for the fall. When the last bell rings for children to be out of school, it is a time for sleeping, spending time with family and friends, playing in the water, taking vacations, AND LEARNING. Children love to learn. Keeping that spark of interest in mind, you want to make sure to work with your child this summer so that skills and topics are...
As teacher professionals, we are all leaders in some capacity. It is important as leaders that we show others how to be their best selves. We need to model for others and support choices and decisions. We must also build relationships that are reciprocal with faculty, staff, and families we work with. I have been in several leadership positions, from a cheer...
Family Forums are something I implemented when I was teaching, and I decided they would become a regular part of building successful relationships with the families in my classroom. I challenge you to take the elements of my Family Forums and incorporate them into your teaching practices because they work!
Family Forums should be just what the name suggests: a time when...
I had the good fortunate of being a principal of seven schools in four states. Something I learned early in my career was unless the superintendent tells you to make these changes immediately or you are extremely familiar with the school, I would wait before I started to revamp what is already in place. If I had to guess a timeframe, perhaps a semester or a year might be a good rule of thumb. What I would consider minor changes could be implemented sooner of course.
I have seen too...
