poetry space science activities A simple magnetometer Tips It is important that when you adjust the location of the sensor card inside the bottle that its edges do not touch the inside of the bottle. Be sure that the mirror spot is above the seam and the taping region of this seam, so that it is unobstructed and free to spin around the suspension thread. The magnetometer must be placed in an undisturbed location of the classroom where you can also set up the high intensity lamp so that a reflected spot can be cast on a wall within 1 meter of the center of the bottle. This allows a 1 centimeter change in the light spot position to equal 1/4 degree in angular shift of the magnetic north pole. At half this distance, 1 centimeter will equal 1/2 a degree. To begin a measuring session which could last for several months, note the location of the spot on the wall by a small pencil mark. Most of the time there will be few detectable changes in the spot's location, so you will have to exercise some patience. Conclusions Related Web Resources

10 Best Places to Live for Escaping World Conflict | Expatify - StumbleUpon Where would you be the safest if World War 3 broke out tomorrow? Perhaps it’s a grim subject, but safety and distance from world conflict can be a motivating factor in your choice to expatriate. At the very least, conflict around the world can weigh heavy on the soul, and it’s nice to know there are some places still left in the world where you might be left in peace. Thus, we’ve assembled a list of the 10 best places to live if you want to escape world conflict. 10. Switzerland’s long history of neutrality and its tucked away location among the valleys of the Alps still make it a safe bet, even despite having a high number of bordering nations. 9. Costa Rica has a stable democracy, a disbanded military and a national policy of neutrality. 8. There are regions of Papua New Guinea that are still being discovered for the first time. 7. Canada is the second largest nation in the world, yet it only shares a land border with one other country– the U.S.A.– and it is a peaceful border. 6. 5.
The Magnetometer Adapted from a TOPS Terra Bagga activity Type of Lesson: Hands-on activity Time Needed: 25 minutes National Standards Addressed Earth and Space Science, Grades 9-12: Movement of matter between reservoirs is driven by the earth’s internal energy and external sources of energy… Physical Science, Grades K-4: Magnets attract and repel each other and certain kinds of other materials. Physical Science, Grades 9-12: Electricity and magnetism are two aspects of a single electromagnetic force… Science and Technology, Grades K-4: Tools help scientists make better observations, measurements, and equipment for investigations. Unifying Concepts and Processes, Grades K-12: Models are tentative schemes or structures that correspond to real objects, events, or classes of events and that have explanatory power.

Scientists measure dream content for the first time: Dreams activate the brain in a similar way to real actions The ability to dream is a fascinating aspect of the human mind. However, how the images and emotions that we experience so intensively when we dream form in our heads remains a mystery. Up to now it has not been possible to measure dream content. Max Planck scientists working with colleagues from the Charité hospital in Berlin have now succeeded, for the first time, in analysing the activity of the brain during dreaming. They were able to do this with the help of lucid dreamers, i.e. people who become aware of their dreaming state and are able to alter the content of their dreams. The research is published in the journal Current Biology. Methods like functional magnetic resonance imaging have enabled scientists to visualise and identify the precise spatial location of brain activity during sleep. The coincidence of the brain activity measured during dreaming and the conscious action shows that dream content can be measured.
