Zoom into Microscopic Worlds
With the Java applet Secret Worlds: The Universe Within, your students can view the Milky Way at 10 million light-years from Earth. Then they can move through space toward Earth in successive orders of magnitude until they reach a tall oak tree just outside the buildings of the National High Magnetic Field Laboratory in Tallahassee, Florida. After that, they can begin to move from the actual size of a leaf into a microscopic world that reveals leaf cell walls, the cell nucleus, chromatin, DNA and, finally, into the subatomic universe of electrons and protons.
