What’s an electrical engineer’s favorite ice cream flavor? Shock-o-late!


It’s all about electricity and CIRCUITS! We will be building and creating our own circuit inventions with wire, copper tape, LEDs, motors, and batteries, as well as working with a cool tool called a Makey Makey. Think of Makey Makey like an external computer keyboard, but with all the keys ripped off so you can mess with the circuits underneath. Using the Makey Makey, you can add any conductive material to the circuit and turn it into a keyboard key! The possibilities are endless! We can build pianos out of bananas, game controllers from gummy worms, or even turn your classmates into keys!

This class is for nerds who are creative, inventive, and sometimes silly! Anyone who finds circuits intriguing and wants to learn more about how electronics work will have a blast in this shockingly fun class!

Nerds in this class make some shockingly awesome electrical creations! Using the Makey Makey and basic circuitry, they can make things like fruit pianos and custom game controllers! We even make some cool artsy circuits like spin art machines. Of course, students are also free to make their own evil genius inventions >:)

Nerds in this class learn about a handful of cool electronics and electrical engineering topics. We will explore electricity, series and parallel circuits, conductors and insulators, and capacitive sensing. We’ll also look at how we can apply some of these technologies into our own creations during class activities!

Our Big Nerds classes for grades 4-7, are engaging and exciting and vary greatly in content and structure, but in some form there is always direct instruction from the teacher, guided practice, and independent or small group work with help and support from peers and staff. We usually begin the day with a team building activity and move into our first lesson. Next is a hands-on activity or project. Halfway through the class, kids will take a brief recess and snack break. A second lesson follows break and the kids will do another project/activity or continue one they were working on. It’s always fun and engaging with hands-on projects!

SUMMER & BREAK CLASSES ONLY: Class is 3hrs each day, so bring a snack for break time. Also, bring your own refillable water bottle. Don’t have one? Add our Nerding water bottle to your order and pick up on first day of class!


Your nerd will build and discover like these nerds have.
