  • STEM kits are a great way to introduce kids to the world of science and technology and build their confidence up around complex concepts they’ll encounter when they’re older.

The Best STEM Kits for Kids That Will Make Them Obsessed with STEM

The problem is that there are so many choices out there for STEM kits that promise to engage kids while giving them a great introduction to concepts in STEM education, but many fall short of their promise because they’re either not well built and designed, have low replay and continuous play value or are not as educational as they are marketed.

Luckily, these are some innovative STEM kits and toys that seem to capture the attention spans of kids. These kits are gold.

Here’s a quick look at our favorites:

What We’re Looking for In A Great STEM Kit for Kids

  • Complete kits and projects that don’t require additional accessories. If they do, we’ve noted it in the description.
  • Kits that have higher replay and free play value.
  • Kits and toys that teach kids some core STEM concepts in a creative way.
  • Price and value of the kits.

Age Range from 5 – 15.

Most of the stem kits are best suited for kindergarten, elementary and middle school. Some may work for younger kids and toddlers if there is adult guidance.


We compiled this based on a combination of kits we’ve tested ourselves, expert opinions, and feedback. We also factored the intrinsic educational value of what you’re getting relative to the price.

For math skills, a great alternative to kits are illustrative math books that are full of activities and problem-solving challenges for kids. These we like better than any math kits, especially if you have younger children.

There’s Also Monthly STEM Kit Subscription Box

We’ve heard great things about the monthly STEM subscription box from Amazon.

However, most of the time sophisticated, high-quality toys and educational play value are not easily combined into one kit or toy.

That’s why it’s an excellent idea for you to teach STEM with along with books and activities as well. Make it a completely immersive experience for your kids.
