My first observation a flea

My students collected, mounted and identified microscopic features of specimens from the school’s garden – all in the field. My students love the Foldscope’s ease of use and the design.

Binder Clip Method of Securing a Glass Slide

Myself and a colleague have built and used two Foldscopes thus far and are very impressed. We tested it with both a prepared glass slide and the paper slide making materials provided in the kit. One thing we noticed was that a glass slide, being fairly heavy in relation to the scope, is hard to…
