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.

Have you heard of Teachers Domain? I stumbled upon it during my search for time elapse videos for the life cycle of a plant.

Each lines up with national standards.
To use the media library~ you will need to register for a free teacher...
I have to share this fantastic strategy with you.
It involves pre-testing your entire class~ allowing students to earn time to work on enrichment/extension activities.
Its an effective way to motivate students and provide them the opportunity to demonstrate what they know and work on perhaps more interesting activities. This method is also a way to offer enrichment opportunities to all higher performing students~ not only those labeled gifted. This way~ you eliminate any...
Although I love winter(I am a skier)~ I am SO VERY MUCH looking forward to the return of my beautiful and colorful flowers to return to my gardens. Daffodils are starting to sprout through the surface as are some of my tulips. Color is slowly starting to take hold in the lawn and I eagerly watch for budding on the trees. To me~ flowers always make me smile!When I retired from teaching I created a teacher garden. Teaching themed chimes hang from shepherd poles and I have a wonderful lilac...
Since Arne Duncan took over as Secretary of Education~ his YouTube channelhas uploaded more than 450 videos and counting (currently 462)~ which follow many of his television spots~ speeches and school appearances and address some of the tough questions he regularly receives. Lately~ he's been bouncing around the country talking to educators and the public at both K-12 schools and institutions of higher education~ all in an attempt to better...
Ask practitioners and administrations on the ground in the education system about state education agencies (SEAs), and you may encounter skepticism. SEAs need not be considered antiquated bodies, as they are the heart of leadership in a states education system. SEAs monitor compliance and accountability, but they also provide support for policy design and implementation. These entities are well positioned to use high quality research in policy and practice, but there is variation in efficacy...
Banning Dodge Ball?
A New Hampshire school district has banned the game many of us grew up playing and probably supervised during recess as adults. The school board felt that the game~ which involves human targets~ is not appropriate. Some people are calling the decision ridiculous. Others are saying it was the right decision.Here's my humble opinion.
Although dodge ball was something I used to play(after my favorite-kickball) and as a teacher~an activity I used to supervise...
In the News-Gustave Whitehead is being credited as having the FIRST successful powered flight in history(Bridgeport~ CT~ on August 14~ 1901)~ two years before the Wright Brothers~ by Jane's All the World's Aircraft. Whitehead's craft~ called the Condor~ did two flights on that date. Reaching 50 Ft.~ the distance covered was 1 1/2 miles.
Things to discuss:
1. Do you think that history books will be changed to give Gustave Whitehead credit for what he did?
2. Why do you think...
In a previous blog~ I addressed the question over whether advanced learners should take part in acceleration or enrichment. In summary~ while I am a strong believer in enrichment activities that develop a students strengths and talents~ I believe acceleration can be beneficial in certain circumstances.
This blog will focus on ways to accelerate a student once they have demonstrated mastery of a particular subject or lesson.
The first step is determining whether a student has...
When a very rough beta version of what industry insiders are calling the "paper phone" emerged last year, people began to wonder exactly how this new, bendable mobile device could be used in a practical way. In a recent filing with the U.S. Patent Office, Apple may be tipping its hand as to how the tech giant envisions using it in future iPhone models.
The...
Recently~ I gave a talk to some students at the University of South Florida regarding methods for working with gifted children.
They posed an interesting question~ one that really got me thinking.
Should you provide enrichment or acceleration when teaching gifted students?
Theres no simple answer. I think it depends on a number of things.
In a perfect world~ you would use both of these approaches to meet the needs of your gifted and higher-performing students. However~ in...
