MEL vs Spangler - Monthly STEM boxes reviewed

Kim Hildenbrand

As with many children, my 8-year-old son is always up for a challenge. He constantly seeks new and interesting things to do, with a focus on hands-on activities—and he’s always looking to understand the hows and whats behind whatever he is doing.

For him, that might mean dabbling in magic tricks, trying to solve a Rubik’s cube, or mixing a few things in the kitchen to see what happens.

As a working parent, I can’t always come up with stimulating activities as often as he would like me to. That’s why we gave STEM boxes a try.

These activity-filled boxes arrive regularly in the mail and come with virtually everything necessary to complete some type of project or experiment. I love knowing he’s getting a fun activity—and I also love the fact that I don’t have to come up with it on my own!

There seem to be an ever-increasing number of STEM box options available for kids of all ages. Recently, my 8-year-old and I took two of them for a test drive.

Below, I’ll share our thoughts on the MEL Science Kids box and the Spangler Science Club. I hope this helps you figure out which box(es) might be the best fit for your own family!

What is a Kids Monthly STEM Box?

You’re likely familiar with the wide world of subscription boxes. These days, you can order a regular subscription for just about anything: beauty products, clothing, and, of course, children’s activities.

While the kid-focused themes can range from anything from art to cooking, one of the most popular types of subscriptions is the STEM box: a kit filled with hands-on projects and/or experiments focusing on science, technology, engineering and/or math (aka STEM).

Many parents appreciate the convenience of receiving a ready-made educational project each month in order to keep kids engaged, entertained, and learning.

MEL Kids Box – What’s Inside?

My 8-year-old son loved the MEL Kids box.  He really enjoyed assembling the LCD screen model all by himself.

Once it was complete, he spent a lot of time observing the way the light changed when it passed through a transparent object. There was also a fun art component, and he loved seeing his own drawings through the window.

This is one of his first experiences with polarizers, and he really soaked up the information and experience!

How easy was setup?

My son was able to complete every step all by himself. There were a few slightly tricky parts, like connecting the pieces, but he persevered and enjoyed himself.

I loved watching him put it all together, and couldn’t help but notice how good it was for his fine motor development.

We greatly appreciated the list of contents as well as the visual instructions. Although he is a strong reader, he prefers visuals when creating a project like this.

Other thoughts:

This project was terrific in virtually every way. The materials are high-quality, the instructions are clear, and the box arrived organised and in tip-top shape.

My son greatly enjoyed building the LCD screen, and he gained some new knowledge and an interest in light.

I also appreciate the fact that this project offered something for different types of learners.

Kids who enjoy hands-on projects will absolutely love the construction process.

Avid young scientists will really dig in to learn about polarisers, dispersion, spectrums, and prisms.

Kids who love art will enjoy creating their own drawings to view as well as seeing the gorgeous colors.

Spangler Science Club Review - Best science subscription box

Spangler Science Club Review

What is Spangler Science Club

Spangler Science Club is a monthly STEM box filled with hands-on activities and interactive experiments. According to the company,

Each box is filled with Steve Spangler’s unique blend of experiences that inspire wonder, boost creativity, enhance problem-solving skills and make learning fun.

The STEMlab box contains up to five experiments (mainly designed for independent use), while the STEMdeluxe box holds up to 10 projects (along with a parent guide).

Who is behind Spangler Science?

The founder of Spangler Science Club, Steve Spangler is a STEM educator, author, and business leader. He has regularly appeared on “The Ellen DeGeneres Show,” and “Time Magazine” named him one of the “most influential people of the year” due to his passion for inspiring a new generation of engineers and scientists.

What ages is the Spangler Science Club subscription designed for?

The Spangler Science Club is designed for children aged 5 to 12 years old.

What’s inside each box?

Each box contains nearly everything necessary to complete the experiments, along with a comprehensive instructional and informational booklet all about the projects.

In addition, the STEMdeluxe box also comes with a “top secret” adult guide that gives all the information about the experiments as well as advice for assisting and teaching the child completing the projects.

How do they compare on price?

The STEMlab box ($19.99 per month) and STEMdeluxe box ($29.99 per month) are both cheaper than the MEL Science Kids box, which costs $34.90 per month.

What did other reviewers have to say?

Spangler Science Club boxes garnered an average of 3.9 stars on 38 ratings on Amazon.

Interestingly, Spangler Science Club seems to fly under the radar when it comes to reviews. They are not listed on several of the major reviewing sites, and the review function is turned off for their Facebook page.

Several individual bloggers have reviewed the STEM boxes. Also, the company features a variety of positive reviews (some with photos) on their own site.


  • The box contains ample projects and materials: The generous number of experiments and plentiful materials means kids can share the kit with siblings and friends.
  • The projects inspire independence: The experiments are simple enough that many kids can work independently and even go beyond the book to explore science on their own.
  • The two guidebooks included in the STEMdeluxe box appeal to all: Reviewers appreciated both the detailed step-by-step instructions in the book for kids as well as the “hows and whys” behind the science in the “top secret” book for adults.
  • The accompanying online aspect is helpful: The company offers links to online videos so kids can see the experiments before they try them.
  • The experiments incorporate everyday items: Reviewers noted the experiments have a strong real-world connection.


  • Some reviewers noted customer service issues: As is common with mailed subscription boxes, in some cases customers had difficulties with the auto-renew feature or shipping issues.
  • Some reviewers felt the boxes were overpriced for the simplicity: A few noted the materials were basic and mentioned the “simple house experiments”.

Spangler Science Club Box – What’s Inside?

When my 8-year-old son opened up the Spangler Science STEM deluxe kit, he gasped with delight.

The theme was “science magic,” and the kit featured six fun activities all centred on performing magic “tricks” using scientific principles.

Mastering these tricks was one of the most enjoyable afternoons he has spent in quite awhile!

How easy was setup?

The setup was a snap. There was a list of items we had to provide ourselves, but most were quite simple such as water, dish soap, and markers.

Within moments of opening the box, my son was starting on his first experiment. The instructions were a bit more text-heavy than some STEM kits’ guides, but there were step-by-step color photos that really simplified the process.

How much did my child enjoy it?

My son greatly enjoyed this science box. “I love everything about this!” he exclaimed repeatedly.

Other thoughts:

My son is passionate about magic, so of course he thoroughly enjoyed these fun “tricks” based on science.

He baffled his brother, entertained his dad, and even greatly amazed himself!

He also learned about friction with the bottle trick

He explored the concepts of cohesion and adhesion with the water trick.

And discovered how polymer chains work with the balloon trick.

He moved fairly quickly through each experiment, but came back to his favorites over and over.

This kit seems to me it would be an excellent fit for children who prioritise fun over learning about science—because the learning comes so naturally.

I also really appreciated both books. The child’s version comes with “lab notes” asking open-ended questions to get kids thinking, and the adult’s “top secret” version provides loads of info on the scientific side of things.

The materials are definite keepers, from the durable plastic “root beer” bottle with the cute label to the sturdy plastic “jar.”

They even threw in extra balloons for the skewer project. My son can perform these tricks over and over.

Would I recommend a Spangler Science Box?

I would absolutely recommend a Spangler Science Box. My son really enjoyed it and had so much fun!

Which is Better, MEL Kids or Spangler Science?

If I had to sum up the experience, I’d say the MEL Science Kids box is a bit more seriously geared to scientific principles and learning, while the Spangler Science box is a bit more lighthearted and fun while still teaching the science.

Overall, both STEM boxes were terrific and (I felt) great value! For my family, the Spangler Science box was the best fit due to my son’s interests.

I believe any child would greatly enjoy either kit. Both feature innovative projects and experiments with clear instructions, durable materials, and extras.

However, a child like mine who loves magic, fun tricks, and entertaining others might lean more towards the Spangler Science box.

On the other hand, a child who is passionate about exploring scientific principles might prefer the more complex science projects found in the MEL Science Kids box.

Attention span may also play a role. The Spangler Science box may suit a child who would prefer several quicker projects, as the MEL Science box features a single project that’s a bit longer and more in-depth.

Children who like hands-on projects that require some building might lean toward the MEL Science Box, while children like my son may prefer to use ready-made items to perform experiments. (If you didn’t already know, Steve Spangler is among the first people who popularized the now-famous Mentos and soda eruption, way back in 2005!)

I know my son will save the Spangler Science materials and repeat these tricks often (he is already planning to delight his classmates). And if he wishes to save the MEL Science kids crystal screen, it is certainly durable enough to do so.

You can view all 18 MEL Science Kids kits online at Mel Science Kids and get some sneak peeks on the Spangler website as well Steve Spangler Science Club. If you’re not sure, I’d urge you to give both of these terrific boxes a try!
