CrunchLabs vs. KiwiCo: Unveiling the Best in STEM Subscription Boxes

Updated: Nov 8

In the world of STEM (Science, Technology, Engineering, and Mathematics) education, CrunchLabs and KiwiCo stand out as prominent players offering subscription boxes designed to engage young minds in creative and educational ways. In this blog post, we'll dive into a detailed comparison of these two brands, exploring their product offerings, target audiences, benefits, pricing, shipping, customer reviews, and wrap it up with a conclusion to help you make an informed choice for your child's STEM learning journey.


CrunchLabs: Igniting Curiosity with STEM

CrunchLabs is dedicated to nurturing young inventors and problem solvers. Their subscription boxes cater to children aged 8 to 14 and focus on science, technology, engineering, and mathematics. The benefits of CrunchLabs include:

  • Diverse Curriculum: CrunchLabs offers a wide range of STEM topics, from robotics and coding to physics experiments, ensuring that young learners get a comprehensive STEM education.

  • High-Quality Materials: Customers appreciate the premium quality materials provided in CrunchLabs kits, making the learning experience both enjoyable and educational.

  • Shipping: They provide reliable shipping options and tracking to ensure timely delivery.

  • Customer Reviews: CrunchLabs receives positive feedback from parents and educators, with many praising the challenging yet engaging projects that inspire critical thinking.


What makes Crunch Labs unique is Mark Rober’s signature blend of creativity, humor, and hands-on science. Each project is paired with a video from Mark himself, where he explains the science behind the build, the engineering principles involved, and fun ways to personalize each project. This combination of interactive projects and expert guidance from a well-known science educator makes learning accessible and engaging for young minds.


What’s Inside a Crunch Labs Box?

Each Crunch Labs box comes packed with high-quality materials and detailed instructions to complete a new build each month. Here’s a look at the typical contents:

  1. All Necessary Materials for the Project - Crunch Labs boxes come with all the materials needed to complete the project, including high-quality parts that fit together easily, reducing the need for additional tools or supplies. The materials are durable and thoughtfully designed for kids to handle safely.

  2. Step-by-Step Instructions - Each box includes a set of clear, illustrated instructions that guide kids through the building process. The instructions are designed to encourage problem-solving, with hints and prompts that allow kids to think critically as they progress through the project.

  3. Exclusive Video Content from Mark Rober - Every Crunch Labs box includes a link to an exclusive video where Mark Rober explains the project, shares insights, and provides additional context around the science and engineering concepts. Mark’s videos make the learning experience feel personal and engaging, breaking down complex ideas into kid-friendly language.

  4. Creative Customization Options - Beyond the main project, Crunch Labs often includes additional suggestions for customizing the builds, encouraging kids to add their own flair or improve on the design, further reinforcing the engineering mindset.


Why Crunch Labs is a Hit with Kids and Parents

  1. Accessible and Engaging STEM Learning - Crunch Labs focuses on making STEM approachable and fun. Each project is crafted to feel like a playful challenge rather than a structured lesson, with Mark Rober’s friendly guidance making the science approachable. The projects are engineered to build fundamental skills in engineering, mechanics, and critical thinking.

  2. Real-World Applications and RelevanceMark Rober incorporates real-world applications into every project, making it easier for kids to connect the science they’re learning with the everyday world. This approach not only makes the projects more engaging but also helps kids appreciate the relevance of STEM in their lives.

  3. Hands-On and Screen-FreeIn a screen-heavy world, Crunch Labs provides an opportunity for kids to engage in screen-free, hands-on play. While Mark’s video adds to the learning experience, the majority of each project requires kids to be actively building, problem-solving, and creating with their hands.


Popular Projects in Crunch Labs

Crunch Labs projects are both fun and functional, ranging from kinetic contraptions to clever mechanisms. Here are a few favorite projects from past boxes that showcase the creativity and educational value of the Crunch Labs experience:


  • The Disc Launcher - In this project, kids create a high-speed disc launcher that shoots small discs across the room. While constructing the launcher, they learn about the principles of velocity, torque, and rotational energy. The hands-on nature of this build keeps kids actively engaged and excited about learning physics concepts.

  • The Hydraulic Claw - The hydraulic claw introduces kids to the principles of hydraulics, as they build a working claw mechanism that can pick up and move objects. It’s a rewarding project that teaches kids about the importance of force, pressure, and simple machines in a way that’s fun to experiment with.

  • The Spinning Top Machine - This project allows kids to construct a spinning top launcher, exploring the concepts of friction, angular momentum, and stability. The kit comes with materials to create different types of tops, which adds to the customization and experimentation aspect.
