Zoom from the edge of the universe to the quantum foam of spacetime and learn about everything in between.

Click "Start," and then use the slider across the bottom, or the wheel on your mouse, to zoom in -- and in and in and in... or out and out and out... It will take you from the very smallest features postulated by scientists (the strings in string theory) to the very largest (the observable universe). This really is a fabulous visual demonstration of scale at micro and macro levels. This is an excellent way to bring spatial thinking into the math curriculum as well.

Earlier I have posted the classic image of "Earth Lights at Night," and discussed the classroom uses of the image.  This cartogram helps take that analysis one step further.  This cartogram helps students to visualize the magnitude of population (with the cartogram adjusting area for population) and then to see the patterns of energy use, global consumption and urbanization with in a new light.

Evolutionary biologists say the first speakers of what would become the Indo-European languages were probably farmers in what is now Turkey — a conclusion that differs by hundreds of miles and thousands of years from a longstanding linguistic theory.

This research potentially can explain much about the geography of languages and the distribution of cultural groups in Eurasia.

This classic image is full of classroom applications.  The first impulse of most students is to note that this image will show us where people live, where the cities are or some other comment that speaks to the magnitude of the population in the white areas.  Let them analyze this for more time, and they'll notice that population isn't the whole story of this image.  A place like India shines, but less brightly than the eastern part of the United States.  I like to point out that South Korea appears to be an island (because North Korea is literally blacked out).  Politics, development, affluence and population information are all embedded in this image.  As with all maps, the more information you have about the place in question (in this case, Earth), the more meaningful information you can extract out of the map.
