Refraction

The purpose of this project is to build a science exhibit that teaches the concept of refraction through written and visual aids. The project uses two lasers, both mounted to be perceived as one continuous laser, to represent the angle of incidence and the angle of refraction through three different media. The user interacts with the exhibit by turning a knob mounted at the lower right corner of the exhibit. The knob has three different settings that correspond to the three different media. Visual aids in the form of icons allow the user to easily identify what refractive medium is being represented. Other visual aids include charts and diagrams that give visual representations of material covered in the text of the exhibit. The written portion of the exhibit gives a short summary of the concept of refraction and the elements that are involved. Working together, the written text, visual aids, and user interaction with the exhibit should provide an educational experience that teaches the concept of refraction.
