This is the interactive microscope that lets young biologists explore the natural world with video-playing slides or their own samples. Eight double-sided smart slides show more than 220 live-action educational BBC videos and images on 15 topics including leaves and flowers, flying insects and crawlers, the human body, food and minerals, and more on the 2.4" viewing screen. Two reusable slides and a tray for larger objects let kids prepare their own samples for viewing at 50-200x magnification. The microscope can store about 100 images in its internal memory and thousands more on a microSD card up to 32GB (not included). Four included adventure games and a quiz game offer budding scientists a fun way to test their knowledge. Includes 4 AA batteries. Ages 5 and up. 9 1/2" H x 5" W x 4 3/4" D. (1 1/2 lbs.)
