Best STEM Toys for Kids

1. Water Rocket (Ages 3 and up)

Quick Review: An amazingly fun STEM activity for any age. Children learn about propulsion by making their own rocket that shoots 90 feet in the air!


Check the price
on Amazon.

Benefits for STEM Learning:

  • This is a really fun rocket activity – I love it and I’m an adult!
  • Great for a child who is inspired by space flight, speed, astronauts or planets.
  • Your child can take the controls – let them press the lever to launch the rocket over 90 feet into the air.
  • Your child learns about the value of fins for flight stabilization, air pressure, and flight pads.

Things you Need to Know:

  • Adult supervision is necessary. It takes off rapidly and could cause harm.
  • Requires a bicycle pump which is not included. Everything else is included.

How it Works:

Use water and air pressure to launch a bottle high into the air. You can attach the fins and set up the launch pad as a family while discussing physics, gravity, air pressure, and other scientific rules of our world.

2. Lego Chain Reactions (Ages 8 and up)

Quick Review: A perfect step up if your child already likes Lego products. This one uses Lego blocks to design and build moving machines.


Check the price
on Amazon.

Benefits for STEM Learning:

  • Great for a kid who loves Lego and would get a kick out of making a chain reaction go off.
  • You can build ten different machines that roll and throw balls, flick up flags, shoot gum, and pull strings.
  • Learn about gravity, physics, centrifugal force and momentum by setting up a chain reaction game machine.
  • Once your child has mastered the basics, let them build their own chain reaction machines.
  • If you already have Lego pieces, you can connect them up to the blocks in this set to create even bigger chain reactions.

Things you Need to Know:

  • Make sure your child already has some skill in using Lego. I’d agree that age 8 is a good starting point for this toy, unless mom and dad get involved in the building of it, too.

Some Runners-Up

14. Coding Jam

Coding Jam (check the price and images on Amazon) connects to your tablet and helps your child learn to code. It’s an innovative hands-on way of teaching coding. Your child lays out their instructions on the table. The tablet takes a picture of the instructions and reads them, then follows the coded instructions to complete moves and games on the screen.

15. Straw Constructor Toy

We usually think of ‘high tech’ when looking for STEM toys. But this straw constructor (see the price and images on Amazon) one brings us right back to the basics of building. The kit includes 300 straws and straw connectors. It’s so simple, but hours and hours of fun. We’ve got one at or house and we build ENORMOUS straw structures with it.

What to Look for in STEM Toys for Kids

Age Appropriate

Some toys might be a little too hard for younger children. I have given some guides about age ranges for all the toys above. However, as many of the online reviews suggest, parents can buy STEM toys for younger children – you’ll just have to provide a little more guidance and support.

Logic and Procedural Thinking

STEM toys should teach logical and procedural thinking. Logical thinking skills include the ability to deduce why something failed and how to solve the error through new attempts. When learning to amend errors, children also learn resilience. Procedural thinking is the ability to follow instructions or strict guidelines to achieve intended results.

Learn about the Laws of the Physical World

Many STEM toys require children to learn about the laws of physics. I have provided several gravity-reliant games above, which show how gravity works and how we can use the power of gravity to cause movement. When we create ramps (such as in the marble project above), we’re teaching children the rules of stored potential energy.

Learn about Computers and Electronics

Some STEM toys focus on teaching how electronic circuits work or how to code them to get desired results. It is incredible how well toys have been differentiated these days so children can learn about coding and the procedural thinking that goes into it – from a very young age!

Fine Motor Skills

Structures that require the use of screwdrivers or the ability to connect objects together require fine motor skills. While we don’t usually think of physical development as a part of STEM, play-based learning is a holistic approach to learning which brings in cognitive, social and physical domains of learning.

Final Thoughts

STEM is vital for children’s development. In their early years, children need maximum exposure to logical and critical thinking to open up those parts of the brain. Inspiring a love of math and science in young children can set them up for life.
