The toy microscope of choice was the Adafruit 5MP USB microscope with a VividiaTM stand for the following reasons: 1) it was more fun to see the objects magnified on a computer screen, 2) the objects could be photographed and videographed, 3) 5MP allows for large screen pictures, and 4) the teachers laptop can be projected onto a wall screen to the whole class for easy teaching. The Adafruit microscope was later replace with a Celestron “true” 5MP microscope. Most USB microscopes come with a stand, however none of those stands have the features of the Vividia stand that moves in both the X and Y axis, and has back lighting. I think this microscope about a good as it gets for a toy microscope, although the price may be an economic barrier to learning for some.
