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."
Note: This is the third and final installment of a three-part series on Type 3 projects for gifted/advanced students.
Now, that you have introduced students to Type 3 projects and helped them plan out their projects, it’s time to manage their work and progress. Of course, there’s a number of ways to do this; I will share what has worked for me. The more students you have simultaneously working on Type 3 projects, the more organized you need to be in your practice. The...

In my last blog, I introduced Type 3 projects—long-term investigations that involve solving real-world problems with real-world products and services. After introducing Type 3s to students through videos, examples, and student testimonials, it is time to begin the projects. If I were to encapsulate the proper starting of these projects in one word, it would be preparation. Students must think through...
Note: This is the first of a three-part series.
One of the best tools I have come across to challenge gifted and advanced learners is the Type 3 enrichment project. Type 3s are real-world, problem-based, long-term investigations. They fall within Renzulli’s Schoolwide Enrichment Model, which you can read about here.

Once upon a time, we thought the only place to meet authors was in bookstores and the only way to network with movie industry people was at film festivals. But look at the disruptive innovations we’ve witnessed, thanks to technology, since the 90’s. There are new platforms and vehicles allowing vast audiences to participate...

A total solar eclipse to cover the USA from coast to coast hasn’t occurred since 1918, and one to exclusively occur only over the United States hasn’t happened since Revolutionary War days (1776). However, that will change on August 21st. On that day, the moon will block out the sun leaving what scientists call a “diamond ring” remaining. The entire solar event will last just three minutes....

In a 21st century world where we are learning, unlearning, and relearning all the time, how can teachers keep up?
The presence of technology in schools is increasing as are the opportunities to integrate tech into practice. However, the moment teachers master one new piece of tech, there may be something...
