This work presents a project for a homemade microscope with a new and alternative way to get spherical lenses, using cheap materials, which can facilitates its construction and use. The simplicity in its assembling and handling encourages its use in poor resourced places and additionally makes it a very portable instrument. Furthermore, suggestions of samples to be examined by students of different disciplines are also presented. This may encourage students and teachers to be more involved in elaboration of and/or participation in interdisciplinary projects. This homemade microscope enables visualization of small structures, their shapes and colors. The use of this simple instrument can grow in the students the desire and interest in the study and analysis of materials and objects in a much more instigating way, then by simple unaided eye observation.
