Secret Worlds: The Universe Within - Interactive Java Tutorial

Secret Worlds: The Universe Within View the Milky Way at 10 million light years from the Earth. Then move through space towards the Earth in successive orders of magnitude until you reach a tall oak tree just outside the buildings of the National High Magnetic Field Laboratory in Tallahassee, Florida. After that, begin to move from the actual size of a leaf into a microscopic world that reveals leaf cell walls, the cell nucleus, chromatin, DNA and finally, into the subatomic universe of electrons and protons. Once the tutorial has completely downloaded, a set of the arrows will appear that allow the user to increase or decrease the view magnitude in Manual mode. Click on the Auto button to return to the Automatic mode. Notice how each picture is actually an image of something that is 10 times bigger or smaller than the one preceding or following it. Earth = 12.76 x 10+6 = 12,760,000 meters wide (12.76 million meters) Contributing Authors David A. Questions or comments?

הסרטון של כדור הארץ מהחלל, הפעם ב-HD - מדע וסביבה בסרטון ששחררה אתמול (שלישי) נאס"א נראים צילומים מרהיבים של כדור הארץ. את הסרטון צילמה תחנת החלל הבינלאומית, שנמצאה בגובה 350 קילומטרים, בתקופה שבין אוגוסט לאוקטובר 2011. הסרטון בן החמש דקות מתחיל בצילומים של ארצות הברית ומסתיים בצילומים ממזרח אירופה ובדרום-מזרח אסיה. בין היתר נראים הזוהר הצפוני והדרומי, המזרח התיכון ומדבר סהרה, מרכז אמריקה ועוד. כמו כן ניתן להבחין במופעי ברקים. סדר הקטעים בסרטון:

For Students K-12 No matter how old or you are, learning about nanotechnology can be fun and exciting. All around the country, we have found new ways to learn about nanotechnology. There are museum exhibits with hands-on experiments and exhibits, and even if you can't get there, you can watch the experiments and visit the museums online. There are magazines with cool stories and games about nanotechnology. Check out the nanotechnology bus that drives around the country and find out when it's coming to your town. There's even a program to learn about nanotechnology by playing with Legos®!

Nanotechnology does not fall under just one discipline such as physics, biology, chemistry, materials science, or engineering, but all these and others. In science, technology, engineering, and math (STEM) education circles, there is an ongoing debate about nanotechnology education: Should it have its own individual curriculum? Or should nanotechnology be woven into the many scientific—and social—disciplines comprising its many elements? This section won’t settle that argument, but it does provide a wide variety of resources to help teachers who are making nanotechnology a part of their lesson plans. The National Nanotechnology Infrastructure Network Education Portal has useful guidelines for approaching how to integrate nanotechnology into your curriculum.
