Unit 14: Electronics


Strange things happen when you run electricity through resistors, capacitors, transistors, diodes, relays, and LEDs… you get FM transmitters, door alarms, police sirens, robot sensors, and much more! And that’s exactly what we’re going to learn about in this unit. We’re going to take the electronic world apart piece by piece so you can truly understand the how and why circuits really work by building several ultra-cool electronics projects.


NOTE: We’re fixing the navigation, so you will notice changes to the menu on the right while we spiff up the website!



We’re going to learn about one of my favorite topics (No, it’s not shooting off rockets – that’s my other favorite ). You’re going to learn about electronics.  But before we dive into doing experiments, let’s talk about what electronics actually is.  First, start with the kind of electric circuits you made in Unit 10.  These kinds of electric circuits use switches, motors, batteries, lights and stuff like that.  In this unit, we’re going to build more complicated circuits that do far more that just turn stuff on and off.  You’ll get the chance to build burglar alarms, FM transmitters and more.


Special Note: This unit builds on the topics covered in Unit 10, and is appropriate for students grades 5-12th.


One of the best things you can do with this unit is to take notes in a journal as you go. Snap photos of yourself doing the actual experiment and paste them in alongside your drawing of your experimental setup. This is the same way scientists document their own findings, and it’s a lot of fun to look back at the splattered pages later on and see how far you’ve come. I always jot down my questions that didn’t get answered with the experiment across the top of the page so I can research it more later. Are you ready to get started?


Unit 14: Electronics Teleclass

This is a recording of a live teleclass I did when this unit was first released. This is a great way to get introduced to the unit you’re about to do and get started. I’ve included it here so you can participate and learn, too! To listen to the audio recording, download the teleclass mp3 here.
