Power of 10
Go immediately to this site for a remarkable experience! This website was recommended to me by list member, Debbie Eaton. It is simply spectacular. You are treated to a journey through the universe that starts with a view of the Milky Way at 10 million light years from the Earth. Then through the magic of magnification and the power of 10, you continue to move through space towards the Earth until you reach a tall oak tree. From there you move into a microscopic world that reveals leaf cells, DNA and finally, you are in the subatomic universe of electrons and protons. Each facet of the journey is 10 times smaller than the previous one – and it all takes place within a few minutes on your computer screen. (Note: When you get to the site, it takes a few minutes for the tour to begin – but be patient, it’s worth the wait.)
After the “tour” you can read about the powers of 10 and exponential notation. As you read the text, you can also click on “Perspectives: The Power of 10″ to review other activities/lessons to further learning – it includes a virtual scanning electron microscope! You will no doubt want to explore the menu at this site as well – there is lots of great science information here.
