STEM subscription boxes are all the rage right now—and it’s easy to see why. Each month, a neatly packaged box arrives at your doorstep filled with hands-on science experiments, building challenges, or coding activities for your kids.
Sounds perfect, right?
But are they really worth the cost? Or do they end up as just another pile of half-finished projects?
After months of testing popular STEM subscription boxes like KiwiCo, MEL Science, and CrunchLabs, here’s everything we learned—what works, what doesn’t, and whether you should hit “subscribe.”
What Are STEM Subscription Boxes?
STEM boxes are monthly deliveries that include projects designed to teach Science, Technology, Engineering, and Math through hands-on learning. They typically include:
- Pre-packaged materials and tools
- Printed or video instructions
- Learning objectives tied to educational standards
- Projects designed for different age ranges
Some boxes focus on specific subjects (like coding or chemistry), while others rotate themes.
Why Parents Love Them
Let’s be honest: we all want to do cool STEM activities with our kids—but we don’t always have time to plan, shop, or prep. Subscription boxes solve that by offering:
- Ready-to-go projects
- Screen-free learning time
- A consistent routine for STEM exposure
- Confidence for parents who aren’t “sciencey”
They also make great gifts, especially for curious kids who love getting “mail.”
What We Tested
We reviewed 3 of the most popular STEM subscription services:
| Box Name | Ages | Monthly Cost | Focus Area |
|---|---|---|---|
| KiwiCo | 0–16+ | $18–$29 | Engineering, Art, Science |
| MEL Science | 8–14+ | $29–$39 | Chemistry, Physics, STEM |
| CrunchLabs | 8–12 | $29.99 | Engineering & Physics |
Each box was tested by actual families with kids across various age groups for at least 3 months.
Pros of STEM Subscription Boxes
✅ Convenience
Everything arrives in one box, ready to go. No last-minute trips to the craft store.
✅ High Engagement
Many projects kept kids engaged for 30–60 minutes or more—without screens.
✅ Confidence Building
Kids loved the sense of accomplishment after finishing each project.
✅ Real Learning
When well-designed, these boxes teach actual science and engineering principles—not just craft projects.
Cons to Consider
❌ Cost Adds Up
While each box seems affordable on its own, over a year you may spend $200–$400+. Make sure it’s being used consistently.
❌ Some Projects Are One-and-Done
Not all projects have replay value. Once built, some are tossed aside (especially in arts-and-crafts-heavy boxes).
❌ Parental Involvement May Be Needed
Especially for younger kids, parents still need to help—and that may not always fit your schedule.
Our Recommendations
🔹 Best Overall: KiwiCo
Tons of age-appropriate options, creative designs, and excellent educational value.
🔹 Best for Science Lovers: MEL Science
Experiments go deep into real chemistry and physics. Ideal for tweens and teens.
🔹 Best for Engineering Buffs: CrunchLabs
Founded by former NASA engineer Mark Rober, this one is a hit with budding builders and YouTube fans.
How to Get the Most Out of Your STEM Subscription
- Pick the right age level – Don’t go “above grade” just to challenge your child.
- Make it a routine – Set one day per month as “STEM Box Day.”
- Extend the learning – Use the toy as a springboard for deeper questions or extra challenges.
- Cancel or pause as needed – Not every month has to be a hit. Don’t feel locked in.
So… Are STEM Toy Boxes Worth It?
Yes—if your child is the type who enjoys hands-on building and experimenting.
They’re especially great for:
- Homeschool families
- Screen-free weekend projects
- Kids who get bored of traditional toys quickly
- Parents who want more meaningful learning without prep work
But if your child loses interest quickly or you’re tight on time, you may be better off investing in a few high-quality standalone STEM toys instead.
