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."
When you walk into an early childhood classroom, what do you expect to see? Teachers, administrators, staff, and educational expects probably expect to see something different than parents, children, or community members. Teachers are usually taught in school what is appropriate and needed to have a warm, welcoming, and appropriate environment for each age level. Therefore, hours of thought are put into how their...

When I was in college, I heard all about centers and how fun they were. I observed in classrooms where centers were placed throughout the environment. Until I got my own classroom, I never really understood the effect that centers had on a classroom setting. I didn’t truly...

When I started teaching, I knew centers were an important part of an early childhood classroom. I knew we learned about them in college, and I had seen them set up in different environments that I had observed. I didn’t fully understand centers and why they were necessary until the second week of school, my very first year...

All teachers use different strategies and learning opportunities for their students. We all know that we need to change our ideas and teaching each year, depending on who our students are, what they know, and what they need. We are usually given a set of curricula that either...

Before school starts, it is important that you, as the early childhood professional, teacher/leader, begin building relationships. There are many things you are probably already doing, but this new year, start thinking outside the box on new ways to build relationships not only...
When we looked at the last article, What Children Need and Want from a classroom, it made me think about what families of children need and want from their classroom and the teacher. If you are teaching young children, this could very well be the first time families are leaving their child. Each family is entrusting...
We know that today is different than last year at this time. I am going to share with you ideas to partner with families right now during the pandemic but also, when things get back to “normal”, as we know they will, ideas for cultivating that relationship.
Right now, families just need support. Teachers need support also. We all need to work together and be kind and realize we are each doing everything...
I think that all teachers have amazing and engaging teaching strategies that we use with the students in our classroom. It’s almost like we are born with creativity and ways to help children and reach families. Creativity is a large part of developing engaging teaching strategies. Having the background of how children grow and develop and what their background knowledge is, is also important to know and...
Think about a classroom, any classroom. When you think of this room, what do you see? What do you hear? If it is your own classroom, you know these sights and sounds by heart, but if you are visiting a new classroom, you may have a lot to learn. As children are welcomed into a new classroom, they have procedures, routines, expectations, and transitions to learn. As teachers set up their daily schedules, they...
