STEM subscription boxes sound like the perfect solution.
Every month, your child gets a new project. Something hands-on. Something educational. Something that (hopefully) keeps them busy without a screen.
But once you start looking into it, you realize there are a lot of options—and three names keep coming up again and again:
KiwiCo, MEL Science, and CrunchLabs.
They all promise learning. They all look impressive. And they’re not cheap.
So before you commit to a monthly subscription, it’s worth asking:
Which one actually delivers real value—and which one is right for your child?
This guide goes beyond surface-level comparisons. It’s based on how these kits actually feel at home—how kids use them, where they struggle, and what parents notice over time.
What Each Subscription Really Feels Like
KiwiCo: The Easy Starting Point
KiwiCo is often the first subscription parents try—and for good reason.
It’s designed to be:
- Simple to start
- Age-appropriate
- Low frustration
Each box usually includes:
- A main project
- Clear instructions
- Small extras or extensions
The experience feels smooth. Kids can jump in without much help, especially in the younger age groups.
It doesn’t go very deep into theory—but that’s not the goal. KiwiCo is about getting kids comfortable with hands-on learning.
MEL Science: The “Real Science” Option
MEL Science feels different from the moment you open the box.
It’s closer to a lab kit than a toy.
You’ll see:
- Real chemicals (safe, but still real)
- Step-by-step experiments
- Explanations behind what’s happening
This is where things get more serious.
Kids aren’t just building—they’re observing, testing, and learning scientific principles.
But there’s a trade-off:
- It requires more focus
- Often needs adult supervision
- Not every child finds it “fun” in the same way
CrunchLabs: The Fun Engineering Experience
CrunchLabs, created by Mark Rober, sits somewhere in between.
Each box is built around:
- A single engineering project
- A clear real-world concept
- A strong “fun” factor
What makes it different is how it’s presented.
The explanations are engaging. The builds feel meaningful. And kids often look forward to the next box.
It’s less about strict learning and more about making kids excited about how things work.
What You Actually Get Each Month
Here’s a typical snapshot of what these subscriptions look like in real life:
While all three deliver hands-on experiences, the depth, difficulty, and replay value are very different.
Deep Comparison: What Actually Matters
1. Learning Depth
If your goal is real academic learning, MEL Science clearly goes deeper.
It teaches:
- Chemical reactions
- Physics concepts
- Scientific reasoning
KiwiCo introduces ideas but keeps them simple.
CrunchLabs focuses more on understanding how things work rather than academic theory.
2. Engagement Over Time
This is where many parents notice a difference after a few months.
- KiwiCo is consistently engaging but sometimes feels repetitive
- MEL Science is deep but not always something kids want to do frequently
- CrunchLabs often creates excitement and anticipation
Some kids use MEL Science occasionally, but look forward to CrunchLabs every month.
Subscription Boxes Kids Actually Stick With
The biggest factor isn’t the content—it’s whether your child keeps coming back to it.
3. Parent Involvement
This is something many guides don’t talk about—but it matters.
- KiwiCo: minimal help needed
- MEL Science: often requires supervision
- CrunchLabs: moderate help, depending on age
If you’re busy, this can make a big difference in how often the kit actually gets used.
4. Frustration vs Confidence
Some kids thrive on challenge. Others shut down when things feel too difficult.
- KiwiCo builds confidence quickly
- MEL Science can feel overwhelming for some kids
- CrunchLabs balances challenge with guidance

5. Long-Term Value
Think beyond the first box.
Ask:
- Will my child still enjoy this after 3 months?
- Does it grow with their skill level?
KiwiCo offers progression across age groups.
MEL Science becomes more valuable as kids grow older.
CrunchLabs keeps interest high with engaging builds.
Which One Is Best for Your Child?
Choose KiwiCo if:
- Your child is new to STEM
- You want something easy to start
- You prefer low frustration
Choose MEL Science if:
- Your child loves science
- You want deeper learning
- You’re okay being involved
Choose CrunchLabs if:
- Your child enjoys building things
- You want a mix of fun and learning
- Engagement is your top priority
A Smarter Strategy Most Parents Use
Instead of picking just one, many parents follow a progression:
- Start with KiwiCo (early years)
- Move to CrunchLabs (engagement phase)
- Add MEL Science (deeper learning later)
This approach matches how children naturally grow and learn.
Screen-Free Learning Advantage
All three options reduce screen time significantly.
Instead of passive scrolling, kids:
- Build
- Experiment
- Think
