IBM Zurich's Lego Microscope

A scientist at IBM Zurich has built a Lego microscope that captures images using a Raspberry Pi and a PiCam. There’s a YouTube video here:, an article in IEEE Spectrum here: and the actual instructions here:

This instrument can be built with off-the-shelf components and a few parts 3D printed using a classroom 3D printer. Do note that there’s about $300 of parts and equipment and a certain amount of precision is needed. Such a project may be more suitable for high school students than for lower grades.
