Build your own microscopes, telescopes & binoculars witht his unique optical construction kit. This innovative kit teaches young scientists how microscopes & telescopes work by letting them build these scopes from simple, reconfigurable parts. Discover first-hand how lenses bend light & learn how they can be combined together to make images larger & clearer for different applications. Build many types of scopes & learn how their various components function. Experiment with different lenses, different tube lengths, & different body configurations. Construct binoculars & a spotting scope. Examine three prepared slides under your microscope & prepare your own slides. Use the telescopes to view far away objects on Earth, & the craters on the moon. Build 28 different models with 147 building pieces. Full-color, 60-page experiment manual.
