If x is negative, then we apply the property of exponents, a -m = 1/a m and then we apply the same logic as explained earlier. If x is positive, we simplify 10 x by multiplying 10 by itself x times. The powers of 10 are of the form 10 x, where x is an integer. This means that we need to multiply 10 seven times, that is, 10 7 = 10 × 10 × 10 × 10 × 10 × 10 × 10 For example, 10 to the 7th power means 10 7. Now, let us try to understand it the other way round. Here, 10 is the base and 9 is the power and this is read as 10 to the ninth power. Therefore, exponents help to express this easily and this value (10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 = 1000000000) can be expressed as 10 9. Now, if we need to multiply 10 thirty times, it would be even more difficult to write the product with so many zeros. If we multiply 10 a couple of times it becomes difficult to write the number as in this case, 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 = 1000000000. These numbers which are written as exponents are the powers of 10. Adjust the settings and play your Powers of Ten.The powers of 10 means when 10 is multiplied a certain number of times, the product can be expressed using exponents.Label your boxes following the example in the video tutorials.Use your range rings as guides to draw squares that are 10m x 10m, 100m x 100m, 1km x 1km and so on.Draw range rings around your center point using the range ring calculator at.Embed your images in a Google Earth placemark at the center of your Powers of Ten tour. ![]() Upload the images to a photo-sharing site, Google Drive, or a school server.PowerPoint will work and is demonstrated in video 1.01 on the tutorials page. If you make one Powers of Ten for the whole class, you may wish to have your class form a ten-meter by ten-meter square and take a picture from a second story window. You might use a piece of playground equipment or something unique to your school or landmark. Featuring items in these pictures can help build understandings of scale. Take pictures showing one centimeter, 10 centimeters, and the entire meter stick. At the center point of your project, take pictures that include the meter stick.All of the work can be done with Google Earth, but the Pro version simplifies some steps. Install Google Earth Pro (now available free).Individual projects make more sense for rural districts, with lower population densities. The project can be done individually, in groups, or as a class. Students may create their own Powers of Ten using their homes or other landmarks as center points. Identify the site you’d like to serve as the center of your Powers of Ten.Tutorial videos are also linked from this page. Watch the video of Google Earth Powers of Ten example.Watch the original Powers of Ten film.It is important for the teacher to run through the procedure prior to attempting with a class. Highlight a key big idea: To Understand (Deep) Time and the Scale of Space, Models and Maps are Necessary.Make maps more concrete for your students. ![]() Why Make a Local Version of Powers of Ten? It is, "A film dealing with the relative size of things in the universe and the effect of adding another zero." See the film and learn more about the Charles and Ray Eames here: The film begins by joining a picnic at a Chicago waterfront park “with a scene just one meter wide, which we view from just one meter away.” Each ten seconds, the camera pulls ten times further away.
