Finding ways to engage children in science, technology, engineering, and math (STEM) can often feel like a challenge. Many educational tools are either too academic to be fun or too simple to provide real value. CrunchLabs offers a unique solution by providing hands-on engineering kits designed by former NASA engineer Mark Rober. These kits aim to teach children how to “think like an engineer” through practical, high-quality projects delivered directly to their doors.
What is CrunchLabs?
CrunchLabs is a STEM-focused subscription service that prioritizes “brain-on” learning. Founded by Mark Rober, a popular personality known for his engineering-focused content, the company focuses on making complex physics and engineering concepts accessible. The goal is not just to build a toy, but to understand the fundamental principles that make the toy function.
The service is divided into two primary categories: the Build Box and the Hack Pack. Each category targets a specific age group and skill level, ensuring that the challenges are appropriate and engaging. The kits are designed to be completed independently by many children, though they also offer a great opportunity for families to work together on a weekend project.
One of the standout features of this service is the integration of digital content. Every kit comes with an exclusive video hosted by Mark Rober. These videos explain the “why” behind the build, showing real-world applications of the engineering principles used in the project.
Choosing the Right Subscription Box
Before starting your subscription, it is important to determine which product line best suits the user’s age and interest level. Currently, there are two main paths to choose from.
The Build Box (Ages 8-12+)
The Build Box is the flagship product designed for children typically between the ages of 8 and 12. However, older children and even adults often find these projects satisfying. Each month, subscribers receive a new engineering project that results in a functional, durable toy.
Focus: Mechanical engineering and physics.
Common Projects: Disc launchers, drawing machines, and vacuum chambers.
Learning Goal: Mastering concepts like momentum, elasticity, and gear ratios.
The Hack Pack (Ages 14 to Adult)
For those who have outgrown the Build Box or are looking for a more technical challenge, the Hack Pack is the ideal choice. This subscription focuses on electronics, coding, and more advanced robotics. It is designed for teens and adults who want to dive deeper into the “hacking” side of engineering.
Focus: Electronics, sensors, and microcontrollers.
Common Projects: Infrared target games, automated turrets, and programmable displays.
Learning Goal: Understanding circuitry, logic, and hardware manipulation.
Inside the Build Box: What to Expect
When you receive your first Build Box, you will notice that the packaging is organized to make the assembly process as smooth as possible. Inside, you will find all the necessary components, including high-quality laser-cut wood pieces, plastic hardware, and specialized tools if required.
The instruction manual is designed with clarity in mind. It uses detailed illustrations to guide the builder through each step. If a child gets stuck, the accompanying video provides a visual walkthrough that clarifies the more complex assembly points. This multi-modal approach to learning ensures that different types of learners can succeed.
A unique element of the Build Box is the “Gear” system. With every monthly build, children receive a physical gear. These gears can be collected and added to a large poster provided in the first box. This gamified element encourages consistency and gives children a sense of progress as they move through the year-long curriculum.
Advanced Engineering with the Hack Pack
The Hack Pack takes the foundational concepts of the Build Box and adds a layer of modern technology. While the Build Box focuses on mechanical movements, the Hack Pack introduces the world of “smart” devices. This is perfect for students interested in computer science or electrical engineering.
Each Hack Pack project is designed to be modified. Once the initial build is complete, the instructions encourage the user to “hack” the device. This might involve changing the code or adjusting the hardware to make the device perform a new task. This emphasis on iteration is a core part of the engineering process.
The materials in the Hack Pack are often reusable or expandable. Because it utilizes standard electronic components, users can often integrate pieces from previous boxes into their own custom inventions. This fosters a creative environment where the learning continues long after the specific project is finished.
The Benefits of Hands-On STEM Learning
Why choose a subscription service like this over a standard toy? The benefits of hands-on STEM kits go beyond simple entertainment. They provide a structured environment for developing essential life skills.
Developing Critical Thinking
Engineering is essentially problem-solving. When a child builds a project and it doesn’t work on the first try, they are forced to troubleshoot. They must look at their work, compare it to the instructions, and identify the error. This process builds resilience and logical reasoning.
Encouraging Curiosity
By showing the real-world applications of physics, these kits answer the common question: “When will I ever use this in real life?” Seeing a lever or a pulley in action makes abstract concepts tangible. This often sparks a deeper interest in how other everyday objects work.
Screen-Free Engagement
While there is a digital component to the instructions, the majority of the time spent with a kit is tactile. In an age of increasing digital consumption, having a physical project to focus on can improve fine motor skills and provide a healthy break from screens.
How to Start Your Subscription
Starting a subscription is a straightforward process. You can choose to pay monthly or sign up for an annual plan. Most users find that the annual plan offers the best value, as it often includes a discount and ensures a steady stream of projects for a full year.
Select Your Box: Choose between the Build Box or the Hack Pack based on the recipient’s age and interests.
Choose a Plan: Decide between a monthly “pay-as-you-go” option or a pre-paid annual subscription.
Set Up Your Account: Provide shipping information and payment details.
Wait for Delivery: Your first box typically ships within a few days of your order.
Access the Content: Use the code provided in the box to unlock the exclusive instructional videos online.
Many families choose to start with a single month to test the waters. Because the subscription is flexible, you can often switch between the Build Box and the Hack Pack if you find that one is too easy or too difficult for the user.
Gifting Options
These STEM kits are popular gifts for birthdays and holidays. If you are purchasing a subscription for someone outside your household, you can easily set up a gift subscription. This allows you to pay for a set number of months upfront.
When you purchase a gift, you can often choose to have the first box sent to your address so you can present it in person, or have it sent directly to the recipient. The subscription will then continue for the duration you selected, providing a “gift that keeps on giving” throughout the year.
Common Questions About the Service
Is adult supervision required? While the Build Box is designed for kids to do on their own, some steps might require a bit of extra hand strength or help with alignment. For younger children in the 8-9 age range, having an adult nearby is helpful for the first few builds.
Can I cancel at any time? Yes, most subscription plans allow you to cancel or pause your subscription through your online account settings. Be sure to check the specific terms if you have signed up for a multi-month commitment.
What happens if a part is missing? The kits are packed with care, but if a component is missing or broken, customer support is generally very responsive. They can send out replacement parts to ensure the project can be completed.
Conclusion
Starting a STEM subscription is an investment in a child’s future curiosity and technical ability. By combining high-quality materials with expert instruction from an experienced engineer, these kits provide a learning experience that is both educational and genuinely fun. Whether you choose the mechanically focused Build Box or the tech-heavy Hack Pack, you are giving the gift of knowledge and the confidence to build something new.
