Prepare a computer with an Internet connection and a projector to watch the Powers of Ten video. (Thanks to for pointing to the original YouTube clip, and Kottke. Print one copy of Powers of Ten 11 x 17 Poster display on your classroom wall. Also check this competition to create a companion video for Powers of Ten, sponsored by design blog Core77, the Eames Office, and Herman Miller. All you do is zoom way out and zoom way in - the universe is just a matter of perspective.įor more, check out “Powers of Ten” on Wikipedia, and the official “Powers of Ten” website. Once we reach 10 24 meters (the size of the observable universe), the camera then begins a faster zoom-in…and goes beyond the original scene, into the microscopic scale and beyond.įor me, “Powers of Ten” is an educational touchstone - it’s a film I was shown several times in science classrooms, and to this day, I find it captivating in its simplicity and power. As we zoom out, we see the earth, the solar system, the galaxy, and so forth. What does the exponent mean The exponent indicates the number of times the base number is multiplied by itself. Created in 1968 for IBM by Charles and Ray Eames (yes, of Eames Chair fame), the film has a very simple premise: start at a static scene, then start zooming out, at one “power of ten” per ten seconds - for example, from 10 2 meters to 10 3 meters. Here the base number is 10 and the exponent is 2.
If you’ve never seen the classic short “Powers of Ten,” I’ve got a treat for you. Finally, the Eames Office has an official YouTube channel (albeit with only one. Here's what I wrote in 2009 about a (now taken-down) YouTube clip of the film: I've written about 'Power of Ten' before, but the videos have been taken down due to copyright claims by the owners. If you haven't seen this classic film from 1977, please take a few minutes to enjoy it. Finally, the Eames Office has an official YouTube channel (albeit with only one video for now) hosting a version that will not be taken down.

Once you have watched, check my video below that has extra practice problems on this subject. Decide if you want the number to have decimal places.
#Power of ten video how to#
Watch my video above to walk through several examples of how to divide fractions by a power of ten. Choose the size of the numbers you would like to appear, as well as the size of the power of 10. We will still add zeros, but we will be moving to the left instead of the right. So for dividing numbers by a power of 10, we will do the opposite. Multiplication increases numbers and division makes them smaller. Now we all know that division is the opposite of multiplication. When we multiplied decimals by a power of 10, we added more zeros to the right, but we had to do a second step to move the decimal point to the right also. The number of spaces that we would move would either be the number of zeros (if our number was in standard form), or the number of places in the exponent index (if it was in exponential form).
That second step was to move the decimal to the right. Then when we multiplied a decimal by a power of 10, we also added more zeros to the right, but we had to do a second step. If you remember, when we multiplied a whole number by a power of 10 (either by the number in a standard form or in the exponential form), we added the corresponding number of zeros to the end of our number to get the result.
