Mini Bulb Projector: A Teaching Aid for Topic on Optical Devices and Light

A student mastery of study material can be observed from their level of understanding on the concept given by the teacher. Th e morevisible the concept, the easier student comprehend it. However, there are many natural sciences phenomena which ar e invisible to thenaked eyes; even though we can see the effects, such as atoms, static electricity, rainbow, tsunami, etc. These abstract conc epts oftenmake students hard to understand them. Therefore, the teachers need the teaching aids to help facilit ate the students to imagine theevent or how the concept occurs. This project aims to develop an integrated teaching aid called “mini bulb projector” that co mbines thestudy materials on optical devices and light. This teaching aid was made of simple mater ials which are easy to obtain, to assemble andto manipulate both by students and teachers. We hope that the teacher can use this teaching aid in our next study to deliver the topic ofoptical device and light to the student effectively.
