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."
Back to school—it's here!
There are many emotions and thoughts about returning to school: excitement, joy, pressure, sadness, and anxiety, to name a few. How you feel depends on your role—whether you're a first-year teacher, a veteran teacher, or maybe it's your last year; a new student in a district; a graduating senior; or a parent dropping your child off for the first time. Returning to school means...
As you begin your new school year, I wanted to share with you something that I did to involve, engaging and build relationships with families----I call them “Family Forums”. I decided that Family Forums would not only become a normal part of building a successful reciprocal relationship with the families in my classroom but also a time to teach and learn from one another. My forums were a party for my families, not a meeting but a place to come and have fellowship with others. It was also a...
As we begin the new school year, stop and reflect on what new things you want to try. Ask yourself how you can make your lessons more engaging or hands-on. Do you need to try new ways of differentiation? What about researching engaging ideas online or observing colleagues? Is there a professional development you have been wanting to attend?
At the beginning of each new year and after each teaching day, I...
It is the most exciting time of the year as teachers start returning back to school. Teachers and administrators are looking forward to the new school year. Many administrators think that this is a time for team building and professional development in the short time before students arrive. As a former principal, I learned that teachers are anxious to get into their classrooms and prepare for school to start.
What I was told was that our teachers appreciated how I approached the...
Want to buy your very own dinosaur? A Gorgosaurus (relative to the T-Rex ) and estimated to be 76 million years old is for sale. It is the only such dinosaur skeleton that will be sold to a private owner and not go into a museum. Gorgosaurus once roamed the earth in what is now Canada and the western USA and this particular skeleton was found in Montana in 2018.There aren’t many such skeletons so it is believed that the Gorgosaurus(...
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...
