NAGC recognizes the challenges that educators experience when faced with providing students with high-level coursework in the STEM fields. In this section, you will find resources that can provide a framework for addressing those issues. Cogito.org was developed by the Johns Hopkins Center for Talented Youth (CTY), in collaboration with TIP at Duke University, CTD at Northwestern, RMTS at U. of Denver, the Belin-Blank Center at U. of Iowa, C-MITES at Carnegie Mellon, the Davidson Institute for Talent Development, the Center for Excellence in Education, and Science Service.

Could you dig a hole all the way to the Earth’s mantle?"
If your family took you on a vacation to the seashore when you were a small child, you probably remember the exhilarating feeling of digging into the wet sand with a plastic shovel. As the hole got bigger and deeper, you naturally wondered what would happen if you just kept digging and digging. How deep could you get? Would you really eventually pop up out of the ground somewhere in China, as your big sister or brother tried to get you to believe? Unfortunately, you never got to find out, because just as you were starting to make some real progress, it was time to pack up the beach umbrella, and go get an ice-cream cone and take a 10-cent ride on the mechanical pony on the boardwalk.Earth's magnetic field reversed extremely rapidly soon after modern humans first arrived in Europe, completely flip-flopping in less than a thousand years. Earth's magnetic field reversed extremely rapidly soon after modern humans first arrived in Europe, completely flip-flopping in less than a thousand years, new research suggests. PHOTOS: Earth Perspectives Through the Ages These findings, detailed Oct. 15 in the journal Earth and Planetary Science Letters, could shed light on how and why magnetic field reversals happen, and how they leave Earth vulnerable to solar and space radiation, the study scientists said.

Sarah Brightman will sing in space
Follow Sarah Brightman on her journey to Russia's Star City to begin her medical assessment for spaceflight. By Alan Boyle, Science Editor, NBC News Soprano superstar Sarah Brightman has confirmed that she's planning a flight to the International Space Station and hopes to sing a song in orbit — but not until after she finishes up the worldwide concert tour that she's just about to start. We've basically known about Brightman's spaceflight gig since August , but today's news conference in Moscow gave the British singer a chance to talk about the multimillion-dollar orbital tour. She told reporters that she's had an "incredible desire" to go into outer space since childhood. In fact, seeing the Apollo 11 moon landing in 1969 "actually inspired me and gave me the courage to go into the career that I have," the 52-year-old said.Aerial Photographs of Volcanic Iceland by Andre Ermolaev
At first glance these photos by Andre Ermolaev look like twisting abstract paintings, but in reality are aerial photos of rivers flowing through Iceland’s endless beds of volcanic ash. Given its name and stereotypical depiction it’s somewhat surprising to learn that the small country named after ice is home to no less than 30 active volcanic systems. You’ll remember the eruption of the massive Grímsvötn volcano just last year that spewed some 120 million tons of ash in the first 48 hours and snarled air traffic for days. Of his photographs Ermolaev says: Iceland is a wonderful country; I would even say that it is a true paradise for all the photo shooting-lovers.

The tests available on this web site were developed by a team of researchers in the Science Education Department of the Harvard-Smithsonian Center for Astrophysics. The content of the questions is based on published studies of science misconceptions and the NRC National Science Education Standards. Research scientists in the specific content areas evaluated draft questions for scientific accuracy and the development team iterated revisions with the scientists until all comments were resolved.

Instruction versus exploration in science learning
Welcome to the fourth-grade science fair, with its baking-soda volcanoes, bread mold grown in drawers, proud parents and thoughtful judges. The teachers can't help but wonder if the young would-be scientists can tell good science from bad. In science, how is critical thinking best taught? This question may be answered by David Klahr, PhD, a psychology professor at Carnegie Mellon University, and Milena Nigam, a research associate at the University of Pittsburgh's Center for Biomedical Informatics. They have new evidence that "direct instruction"--explicit teaching about how to design unconfounded experiments--most effectively helps elementary school students transfer their mastery of this important aspect of the scientific method from one experiment to another. Their assertion is based on years of research, including a controlled study presented in March at the U.S.
