Why Choose a CircuitWhiz Kit?

Unlike other science kits our kits combine * hands-on challenges*  with the *excitement of leveling up* which allows your child to learn real scientific concepts all on their own WITHOUT you needing to do anything!

Finally! A science kit that teaches problem solving not following directions...

Most science kits focus on the end result.  Follow these instructions, do these things, and voila! You now have a cool doodad.

But do your kids actually know why they did what they just did?  Do they actually understand the science behind what just happened? 

Probably not...

But at least they did what they were told!

Real science learning, isn't simply about knowing the "right answer"

A quality science education will encourage kids to problem solve, experiment, try again, and work towards a solution. 

As they solve these problems, kids will start to discover important scientific concepts on their own, and a quality kit can highlight and clarify what they just learned and accomplished.

We love the circuit kit! My kids love that they get to be creative and solve problems by themselves. I love that they are getting a high quality introduction to electricity! We’ve tried multiple circuit kits and this is the best by far. Linsey is a master teacher. Between the short videos and the hands-on learning, these are science principles my kids won’t easily forget.

They were actually learning

The CircuitWhiz kit is the only learning kit I've ever seen that actually had my kids and me learning, not copying. It challenged all of us to really engage in a scientific mindset, asking ourselves questions, experimenting, and drawing conclusions. There is so much room for growth throughout the kit, not just a one and done. I can't recommend the CircuitWhiz kits enough!

They Want to Wire their Doll House

My kids have LOVED this. It's been amazing to see them internalize the ideas and problem solve. They now want to wire their doll house with lights and switches. Do you have any suggestions where to buy the electrical components for that?

What Makes our CircuitWhiz Kits Unique?

More Than Just Following Instructions – A Journey in Problem-Solving!

Most science kits rely on step-by-step instructions or copying images.

With CircuitWhiz, kids aren’t just following directions—they’re actually solving problems.

Each challenge bag introduces a new mystery, encouraging them to think critically and learn real concepts in circuits as they work toward the solution.
  • Forget “copy and build” projects. CircuitWhiz encourages kids to discover, experiment, and find solutions on their own.
  • Boosts confidence with each completed challenge, helping them develop pride in what they learn and achieve.
  • Captivates kids with hands-on problem-solving, making each new level feel like a fresh achievement.

Packed with Over 30 Real Components and 15 Levels of Fun!

With more than 30 real electrical components and 15 unique challenges, CircuitWhiz doesn’t end after a single project.

Each new challenge builds on the last, keeping kids engaged long after the first use.

They’ll continue learning, playing, and inventing as they explore all that CircuitWhiz has to offer.
  • Real parts for a real learning experience that feels like hands-on science—not just another toy.
  • Mystery bags reveal new components and challenges, sparking curiosity and excitement with every new level.
  • Perfect for kids ages 8+ who love to tinker, explore, and take on new challenges.

No Screens, Just Discovery and Achievement!

Kids love the thrill of leveling up in games.

CircuitWhiz brings that same excitement into a learning journey—without the screens!

Each new bag keeps them guessing, each challenge feels like leveling up, and they’ll be eager to share every new accomplishment with you.
  • Screen-free fun with an emphasis on learning and curiosity.
  • Challenges progressively increase, so kids stay motivated as they learn.
  • Every challenge is another achievement, giving them a sense of pride and accomplishment.
NOTE:  There is an option to watch a 2-minute video for each level where Linsey shows the solution and explains the science behind what the kids just learned.  This part is optional as the science is also explained on the cards.  But this is a great alternative for kids that prefer learning from others rather than reading themselves.

Something They Can Do on Their Own

Want to support your child's learning journey, but don't have time or expertise to initiate everything?  

Everything you need is inside this kit. 

No expertise or other equipment required.
  • Open up the kit and get started right away, diving straight into the first challenge—no adult preparation required.
  • Encourage independence yet also an opportunity to celebrate together as they finish and show off each challenge—giving you a chance to tell them how proud you are.
  • Perfect for busy parents who want to support learning, but can't be the one to teach it all the time.

How does the CircuitWhiz Kit Work?

Open the Level Bag

There are 15 different levels, each with a unique challenge and secret electrical components.  
When your child opens the bag, they get a challenge to complete and everything they need to figure it out.  They get to jump in and start problem-solving right away!

Solve the Challenge

Real hands-on experimentation with lights, switches, motors, LEDs, resistors, and more allows kids can explore the world of circuits like true scientists.  The joy is real and exciting as they discover the solutions to each challenge.

Learn the Science

Each level has a specific science principle the kids will learn. They can read about the science themselves on the challenge cards, or they can scan the QR code to watch Linsey teach a 2-minute science lesson.   This gives kids independence to experiment AND learn science along the way.

He LOVED it

My 10 year old son LOVED this. He thanked me for getting it after the 1st level package. He worked on it for about 2-3 hours straight and I didn’t hear one word about playing on the Xbox that whole time. He LOVED it!!! And it’s definitely something he’ll continue pulling out again and again to use

One Year Later

We love our circuit kit! My kids still play with it regularly a year after the initial purchase. We even ordered extra copies so everyone can play at once. Every friend who comes and sees it ends up ordering one themselves (or asking Grandma to get it for them!). Even I learned more about circuits as I played with my kids. I can’t recommend this enough!

Just the Right Challenge

We bought a Circuit Whiz kit and it has been the best thing ever!!! My kids LOVE it! It's challenging enough that they don't just breeze through it and it takes them a bit of time to work through things and figure it out. But it's also not too challenging or overwhelming that they get discouraged. It is so well thought out, with great info, so my kids are able to do it without my help. It's the perfect activity! And totally reusable to allow kids to continue learning, experimenting, and discovering. It's so awesome!!!

This is ideal for ages 8-14, though we've had plenty of adults and older teenagers that have learned a lot and been stumped by some of the puzzles.  We have had plenty of 7-9 year olds go through it and love their experience too.  If they're younger than 7-8 then we suggest waiting a year or two so it's not as difficult and they can enjoy it more.

Each level covers a different topic. Over the course of all 15 levels kids come to understand the topics of:

  • Complete circuits
  • Positive and Negative charges
  • Voltage
  • Parallel and Series
  • Morse Code
  • Resistors
  • and More

Over the course of all 15 levels, kids will open up packages that include items like:

  • Lightbulbs
  • Batteries
  • LEDs
  • Motor
  • Switches (multiple kinds)
  • Buttons
  • Resistors
  • Magnets

Hi!  We're the Jensens.  We are a homeschooling family of six that loves science and games.  Linsey (Mom) has a bachelor's in physics and a master's degree in education.  Scott (Dad) has a PhD in physics.  And all four children are great play testers of all our experiments. 

We are most proud of this game because of the way it uses our physics knowledge, education and parenting experience, as well the fun and excitement of games to create something truly captivating and memorable.  

These kits are hand put together in our home in Heyburn, Idaho by everyone in the family.

Did you learn to ride a bike by reading instructions? As humans, we all learn better through experience, through trial and error, and through problem solving.  Not from reading a textbook.  Each of the 15 challenges guides kids to discover solutions through problem-solving, allowing them to learn by experimenting and exploring. 

The challenges are specially curated to slowly but surely build on each other so that it pushes kids to the edge of their understanding -- everything is within their grasp.  It’s designed to be engaging while building confidence and real understanding because they are solving real problems!  

Nothing beats the look on that child's face when they get that lightbulb to light up all by themselves!

Most kids will spend a couple weeks progressing through the levels.  Plan on 4-8 working hours to get through all the challenges if they don't have any experience with circuits.  The beginning levels are easier and kids can go through them quickly once they get the hang of of it, but the levels at the end of the kit are tricky even for adults!

Once the challenges are finished, kids will have all the components they need to make their own circuits.  Everything is reusable and they can create and take a part different creations to their hearts content.  So this kit doesn't end after the challenges are completed.

Yes!  Everything in this kit is reusable.  Each of the components can be used over and over again.  It does include AA batteries that might need to be replaced eventually.  And there are extra lightbulbs included for when the original ones burn out.

Not only that, but the entire kit is resettable!  On each level's challenge card there is a list of the components needed to solve that challenge and the bolded items are the components that go in that bag.  So if your child wanted to reset the kit for someone else to try they can put the components in the correct bag and it will be all ready to go.

No worries!  I got you!  This is meant for beginners and veterans alike.  The first few levels are pretty simple to help the players understand the basics of electricity.  Also included are some basic "troubleshooting tips" that covers the most common situations that kids get stuck (for example, when the alligator clips are attached to the plastic coating instead of the actual wire).  

There have been plenty of families go through this kit not knowing anything about electricity to begin with and come out at the end as Circuit Whizes!
