Are you struggling to keep up with your kid's questions about science and engineering?

Do you want science and engineering activities that build on your student's existing interests?

Are you searching for mentors that can help a learner you love explore a budding interest in engineering?

Do you want challenges that encourage your student to go deeper?

You have found the right place.

Welcome to the Curiosity Club, a hub of connection for curious kids interested in exploring science and engineering.

The Curiosity Club is the place for anyone who wants to learn more about engineering. Encourage your kids to ask the big questions that matter while in a supportive online environment. Your kid will be challenged with fun, hands-on, creative engineering design challenges that keep them coming back for more. New design challenges are released every week.

In the Curiosity Club, you will find high quality, unique, and innovative engineering design challenges you could do today with supplies found in your house. All design challenges are led by an experienced engineer with a passion for mentoring the next generation of problem solvers.

All members of the Curiosity Club will have the opportunity to practice being real engineers, scientists, and inventors. Watch the learners you love discover the world of engineering, make friends around the world, and confidently solve problems big and small.

Weekly design challenges include prompts like:

  • Invent a better water bottle
  • Create your own fidget cube
  • Devise efficient ways to tunnel through fruit
  • Design scissors that can cut through playdough
A stack of sample resources you may find in the Curiosity Club [6 covers are overlaid with Airplane Explorations, An experiment log for Will It Float or Will It Sink, Adventures with Physics, "The Flight of the Bumblebee" Design Challenge, Engineering Medieval Europe, and Engineering of Everyday Things: The Clothespin]

What are office hours?

Office hours are live video calls with me! I am more than happy to jump into a Zoom videoconferencing room and help learners all over the globe. As founding members, you get to help me craft an office hour schedule that meets the need of our global community.

But.... what supplies will I need?

Great question!

Every challenge is designed to work with items you already have in the house or can find easily at a grocery store, general merchandise store like Wal-Mart or Target, or a hardware store. 

I recommend stocking a home makerspace with the following supplies:

  • Recyclables such as cardboard and plastic
  • Rigid materials like craft sticks, straws, wood dowels, paint stirrers, balsa wood, and stiff foam
  • Flexible materials like foil, paper, pipe cleaners, wire, rubber bands, and flexible foam
  • Adhesives like hot glue, duct tape, and masking tape
  • Tools such as high quality fabric scissors, wood cutters, hot glue guns, and screwdrivers (and yes, screwdrivers are amazing when you're constructing things out of cardboard)
  • Other craft supplies that your kids use often

I also frequently encourage students to generate supply lists comprised of edible materials. Experience has shown me that kids have an easier time thinking about material properties if they are working with objects like licorice and raw spaghetti.

If you're having trouble finding good supplies for a particular challenge, just ask me on the online community.

How much time does each challenge take?

This can vary a lot. When students engage every aspect of the engineering design process, most challenges run between 1 and 4 hours. I deliberately encourage students to try different ideas, and some students develop a long-term interest in projects. Weekly design challenges don't expire, and I'm more than happy to continue supporting your student. I think of challenges as an invitation to explore. It's great to see when students immerse themselves in the process.

What if the challenge is too difficult for my student? What if it's too easy?

I do my best to provide enough scaffolding so every learner can find their footing. I am constantly interacting with members of the Curiosity Club community. Just post in the community or send me an email, and I'm more than happy to help.

Every challenge comes with an interactive notebook to help guide students through the engineering design process. I believe that everyone should have the opportunity to explore engineering, and I'd love to help your family get the most out of your experience.

My oldest is only 5.... Wouldn't it be best to wait?

I'm of the opinion that all kids start out as scientists and engineers. Grabbing a family membership now is a great investment in your kids' curiosity.

Encourage active, engaged exploration

Kids need opportunities to ask big questions and explore their own interests. They want hands-on, open-ended challenges that allow them to use their imagination and see the results of their creativity.

The Curiosity Club incorporates original hands-on engineering design activities that delight learners and keep them thinking. Every challenge comes from the real world and uses supplies that you already have around the house. As kids complete the weekly challenge, they develop a strong sense of pride in their problem-solving skills and abilities to create awesome things.

Practice being a real engineer, scientist, and inventor

Kids want access to the real deal when they explore engineering. They want to know what it's really like to be an engineer, scientist, and inventor. They are actively making decisions about their future and crave authentic experiences.

The Curiosity Club supports learners in discovering how to use engineering design processes and scientific inquiry. We journey through the process together through its ups and down. The Curiosity Club honors how kids learn and provides lots of space for them to celebrate their achievements in a global community.

Access high-quality mentoring from a passionate educator

We learn best when we gather together. With so much out there that promises to help kids explore engineering, it can be difficult to find quality experiences. Kits can only take you so far.

The Curiosity Club goes beyond kits by providing facilitated learning experiences. Questions are always welcome, and, in an online community, the lights are always on. When learners ask questions, they will receive answers tailored to their specific needs. Design challenges are crafted from a place of consistent interaction making the Curiosity Club the premier place to encounter engineering.

Parents Praise for Opportunity Unlocked

My kid said he felt like MacGyver. So if your kid likes to feel like MacGyver, put them in this class or one of this teacher's other engineering classes. -Tiffany

My 13 year old daughter really enjoys Lindsey's classes. Lindsey bends over backward to take care of students and make sure they are getting what they need. We will definitely be looking for Lindsey's classes in the future! -Johanna

My daughter loved rigging things up with stuff we had around the house and I loved watching her imagination ignite and creativity spark with ideas, then when she brought them to life and the pride she exhibited was so wonderful to watch. -Mandy

Lindsey always strives to offer a class that is good cost-value, educational, and useful. My 15 yr. old son enjoyed the concepts covered and the hands-on approach. -Jean

The Tunnel Boring Challenge, a Great Civil Engineering Activity for Kids

The Tunnel Boring Challenge, a Great Civil Engineering Activity for Kids

Civil engineering is more than bridges and towers. Civil engineers create infrastructure that makes our lives possible. Every day, civil engineers are at work designing subway systems, safeguarding the water supply, and ensuring highway safety in and through mountains. But how can adults give kids accessible, understandable, and fun ways to explore infrastructure?  It’s time…

Reimagining the Classic Tower Design Challenge

Reimagining the Classic Tower Design Challenge

Involving kids in engineering can be easy and fun if you can combine creativity, curiosity, and a spark of imagination. You don’t need special supplies to do it. Certain design challenges, like the classic egg drop, come up frequently. Another classic design challenge is designing the tallest tower from spaghetti and marshmallows. Tower design challenges…
