In a case of life imitating art, the European Space Agency is working on an experiment designed to launch a projectile into space and collide with an asteroid in an effort to alter its path away from Earth.
"Concepts are being sought for both ground- and space-based investigations, seeking improved understanding of the physics of very high-speed collisions involving both man-made and natural objects in space," the ESA announced in a statement.
The plan will culminate in a large-scale experiment in 2020, at which time two spacecraft will be launched in the direction of a 2,600-foot asteroid called 65803 Didymos. One spacecraft will intentionally crash into Didymos, attempting to alter its course, while the other records the results.

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.

During my last blog~ I shared a story about how problem-based learning was used to challenge one of my students.
In this post~ I want to outline the steps that have personally helped me implement this method.
First~ you have to find the right problem.
Problem-based learning~ or PBL~ is personalized for each child. It requires differentiation at a very deep level.
According to Dr. De Gallow at the University of California~ Irvine~ One of the primary features of Problem-...

Improved technology played a big role in the identification of the two primary suspects in the Boston Marathon bombing.
Law enforcement officials were deluged with digital images and video after asking anyone who was in the area during the event to submit them. Traditionally it would take hundreds of officers countless hours to examine...
The invasion of the Giant Snails sounds like a science fiction movie title but in Florida~ it's very real. The giant African land snail has invaded the state and since they have no natural enemies~ the snails are causing quite a problem. As their name suggests~ the snail is very large...think the size of a rat. And~ the giant African land snail multiplies quickly. Just one female can produce 12~000 eggs in one year! The giant African...
Ali Razeghi, a scientist from Tehran, claims to have successfully created a time machine. According to The Telegraph, Razeghi's machine is not a time traveling device in the classic sense. That it, it does NOT...
Id like to dedicate my next few posts to the topic of problem-based learning.
It is certainly a method that motivates students~ helps them develop valuable how-to learn skills~ and makes learning relevant. Before I get into the particulars~ Id like to use this blog to share a true story illustrating the power of teaching through problems.
(Please feel free to share your stories of problem-based learning or post comments by visiting the Gifted/Enrichment group at...

I wasn't much of an athlete growing up. I hung around other kids who played sports, but I was never really good at any of them. Baseball, football, and soccer just didn't make sense to my body.
Take baseball for example. To me, the idea of failing to hit the ball was more anxiety than I could take. So I'd stand there...
