Grade Level: 6th - 12th; Type: Mechanical Engineering
Design and build a working slide projector. The goals of this project are:
- To design a fully functional mechanical invention.
- To create an interesting visual display.
- How does a slide projector work?
- What is the latest slide projector technology?
- What are the uses for a slide projector?
Building a slide projector is easier than you might expect. Yet, many people will think you're a genius for building one. This project invites you to build a basic slide projector out of ordinary materials. You'll also learn how to make the slides.
