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."
I recently saw a photograph (on Facebook) of a large trash can/bin stuffed full to overflowing and the caption read, “This is our school curriculum!” I laughed and thought – I can relate to that! I think an overstuffed curriculum makes for a stressed teacher, and sometimes we forget to have fun and make connections with our students.
Why did you become a teacher? To teach the curriculum? I would guess, no! To design assessments with appropriate criteria? I would guess no! To create...

As teachers, we know that student writing and reading are intrinsically linked. Sometimes, all it takes to bring out their inner writer is the right book. So, how do we find those perfect books to help our students grow as writers?
Our friends over at Primary Paradise dive into Using Real-Aloud Connectors to really ignite writing in K-5 students. It’s so important to share rich, engaging books with our students...

Happy Birthday, Hans Christian Andersen! (April 12th)
Did You Know?
1. In 2012, a fairy tale of Hans Christian Andersen was found. It is believed to be his very first story, written as a teen. The six page story...
Please go ahead and finish this statement: a gifted student is like…
What did you say or write? What images did your simile draw upon? Do you view gifted students as “shining star,” “shooting rockets,” or “diamonds in the rough?”
If your similes were predominately positive, you are not alone. A study (Olthouse, 2014 ) found that pre-service teachers mainly represented gifted students in this fashion. The group inaccurately believed, for example, that gifted students almost...
When you have people together for any amount of time, a culture emerges that consists of a set of customs, beliefs, values and norms. This culture can either create a sense of mutual purpose, a mission, a vision, values and goals or perpetrate discord. Every school has a culture whether you work on the culture or not (Barth, 2003). Culture cannot be seen but it is there. It is an important aspect of school.
Culture consists of the beliefs, feelings, behaviors, and symbols...
Principals play a key role in facilitating the work of experienced teachers who serve as mentors, including preparing them for the role. Veteran teachers may have little experience with the core activity of mentoring---observing and discussing pedagogy with their colleagues.
Many teachers, especially those teaching in secondary schools, often work in isolation with little contact with their peers. This isolation, coupled with the lack of opportunity to observe and discuss each other’...

“Thirty years ago global warming was not widely understood,” observed Richard Robbins in our 2013 interview with him about his acclaimed film, Girl Rising. He believed the most powerful argument in favor of educating girls was as a strategy to eliminate global poverty.
