Video Podcasts: The Incredible Two-Inch Universe

What You'll Need

View/Listen
Wrap your mind around the vast distances in the universe. What you'll need: a measuring tape, 6 round images from the printable 2-inch universe PDF, a grain of salt and a wide open mind. What to do: explore the universe by shrinking cosmic scale in four steps zooming out from the realm of Earth and moon to the realm of the galaxies. At each step hold up the image that represents that cosmic object scaled down to 2 inches (about 5 centimeters) in diameter. Ask a friend to predict the scaled sizes and distances of the objects before you reveal the answer.
