Abstract

In this work it is presented a didactic and low-cost experiment, in a simple and intuitive way, called water drop projector. This experiment can be a more efficient alternative to the use of microscopes for observing microorganisms in the classroom, because it can be viewed by several people at once and its components are easily accessible. The physical foundation of the experiment is based on optical concepts and can be performed in a dynamic and interactive way, providing a discussion about light interaction with organic matter and the wave and geometrical features involved. The water drop projector can be used in classes of different disciplines both exact and biological, in primary, secondary and higher school levels. Initially, the experimental methodology is shown, as well as suggestions on alternatives material for experimental setting. Next, the physics involved in image formation is described and several applications that can be done in the classroom are demonstrated. The main goal of the work was to explore several approaches that can be done with the experiment, in order to show its scope and easiness to interact physics with other areas of knowledge, such as biology.
