Hands-on projects that can be completed by students inexpensively and in a reasonable amount of time. One example that students can complete in a little over an hour is an LED circuit that lights up their initials. The students consider engineering tradeoffs such as high brightness versus battery life, and this circuit is very easy to debug, making it a satisfying experience.
Other projects, which were mostly developed by ECE students, include:
- Audio equalizer: Allows students to play music through low pass, high pass, and band pass filters, and relate this project to physics concepts
Infrared heart rate monitor: Makes a light blink with your pulse
Jeopardy game buzzer circuit, accompanied by a Jeopardy game
DC motor using a battery and magnet to make it spin
Speaker: Build a working speaker using paper, wire and a magnet!
Smart lighting teaches students about saving energy by building a circuit to turn the lights out when not needed
3D optics: illustrates the physical principles of 3D perception, how 3D glasses work, and lets students generate their own 3D images
The projects make perfect hands-on activities for school classrooms and STEM Clubs (Science, Technology, Engineering, and Math). Each project has a set of instructions and explanation of the physical principles being applied, a slide presentation that could be used in a classroom, and, in some cases, a student handout. The documentation was written specifically for educators, so teachers can complete the activities independently. Instructions include parts lists and vendors.
Prof. Anderson’s outreach group is available to visit Columbus-area schools to lead the projects described above. Interested school teachers for second grade and up may email email@example.com for more information.
