S.T.E.M. Class

Speedster Physics

Grades: After School 3-6, Summer 4-7

Build, test, improve, race!

We have awesome flexible tracks for creating loops and stunt tracks! Design and build your own racers and show off your skills in speed, distance, and style in a friendly, supportive, and energetic environment! Test and tweak variables to optimize your design, and discover the science behind your cars & tracks.

Q: Why couldn’t the frog find where he parked his car? A: He’d been toad!


We’ve added flexible tracks for stunts and loops which has changed about half of the physics lessons in this class. You’ll love taking this again if you took “Racer Engineering” last summer!

Get ready to become a Racer Engineer and explore the thrilling world of physics in a wild ride of fun! In this class, you’ll design and build your own racers to race down our 32ft straight track and showcase raw speed, as well as mastering loops, jumps, turns, and stunts on our 5 additional 25ft flexible tracks. We will also build and test other speedsters like planes, drop copters, and stomp rockets!

But this class isn’t about winning, it’s about learning how to test and tweak variables to optimize your design, problem-solve to overcome challenges, and discover the science behind your creations. With friendly, supportive, and energetic racing and stunt showcases, get ready to experience the rush of Racer Engineering and unleash your inner problem solver!

***This class is open to ALL kids entering grades 4-7, and girls, this class is perfect for you! We believe in empowering young girls to explore their passion for engineering and science. Just remember girls, science is ALWAYS FOR YOU. 

This is the ideal class for anyone who loves to make things out of recyclables, and anyone who loves building! If you think you’d enjoy designing and building your own car out of cardboard and creating crazy tracks and tricks for it, you will LOVE this class!


Nerds in this class makerace cars out of recyclable materials. Nerds will design their own cars and spend the week building, testing, and improving upon their designs. Students in this class gain a lot of insight into how small design details can drastically change performance, like the way they place the wheels on their car or the way the car’s weight is distributed.

We will also build other types of speedsters, like planes, drop copters, and stomp rockets!


Nerds learn about some basic engineering principles like simple machines that they can use to put their cars together. Throughout the building process, nerds figure out how their car’s design affects its performance, and see how changing small details can have a big impact.

Nerds will also learn about the Engineering Design Process, a process that engineers use to design, build, and improve their creations. They will be able to test their racecars and conceive ways to make them even faster and stronger. Through this process, nerds learn about planning their creations and being willing to make changes to make them better, even if it means doing something over again.


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.
