The Microscope Explorer Kit is a valuable tool for the young to the older for exploring anything from coins and stamps to the hidden world of nature. It features a 20X stereo microscope, 3 genuine ancient coins, a cleaning brush and tweezers. Learn how to use a microscope as you discover where these coins were minted, how they were made, and who they were minted for. But the fun doesn’t end with the coins. A stereo microscope is a great tool for discovering more about the world in which we live. Look at rock formations, insect habitats or sand from the beach. Because it’s battery operated and lightweight it can go almost anywhere. A great field trip microscope. The unit is 8×2.5×5″ and requires 2 AA batterises (not included). Age:7+.
