21 STEM Kits For Elementary School — Open A World Of Wonder

STEM Kits for Elementary School

The study of science, technology, engineering, and mathematics (STEM) declined at the end of the last century.

That is why…

The U.S. Department of Education recommended children be taught the STEM curriculum from the very beginning of their schooling. This curriculum is hands-on and requires certain resources to make it engaging to children. The simple answer is STEM Kits.

A classic and proven example is the Engino Discovering STEM Structures Constructions & Bridges which made it to the top of my list. I love how it focuses on structural engineering and force and my young students enjoy learning how architecture works.

If you are an elementary school teacher or have young children, read on. You will find an amazing variety of STEM kits to make your life easier and your children’s life more fun.

STEM Kits Explained

STEM is a curriculum that covers four basic science topics – general science, technology, engineering, and math. The method of instruction is interdisciplinary and interactive, so children learn these subjects as a cohesive whole and not as separate disciplines.

The fun part is the lessons are based on real-world applications. At the end of the lesson, children have something in their hands they can be proud of, and they understand the science behind it.

A STEM kit has all the material you need in one place to teach a STEM subject. For example, children can make their own coding robots or create their own solar houses. These are just two of hundreds of kits for teaching application-based science, technology, engineering, and math.

I have selected a few of the STEM kits I found that are great for elementary school students. Several of the kits I recommend above are made by Snap Circuits. They have won many awards, including the inaugural Seriously STEM award, Good Housekeeping Best Toy, and National Parenting Publications Award to name just a few.

I have used STEM kits for elementary school with my students as well as with my own children. The kits are an amazing tool when teaching a STEM curriculum. You can make your own kit, which I will talk about below, but DIY is time-consuming and sometimes unsuccessful.

STEM supplies make everything easier and they are so child-friendly that half the teaching is done for you. There are kits that focus on different aspects of STEM as well as interdisciplinary kits.


As I mentioned above, you can make your own science materials for classroom use perfectly well. You just need to collect a few common objects and ingredients that you have on hand or can easily buy. Start in the kitchen. Collect items such as bicarbonate of soda, vinegar, Borax, paper towels, white glue, starch, food coloring, and other things you can buy in a grocery store that are listed on this website.

The website shows exactly how to use the ingredients to make the science projects such as acid/base combination to make an erupting volcano or blow up a balloon, separating fat from liquid, which means making butter and eating it on bread and how certain ingredients combine to form different types of materials.

Each of these examples is easy to do and the outcome is something fun. It even includes specific activities for the seasons, such as how to make a foam snowman or weird Halloween decorations.

Children and some adults can’t believe you can make your own bouncy balls, slime, and all the derivations that are possible. My children made bouncy balls as gifts for their young cousins and friends.

This video is a great resource for making DIY STEAM kits:

The teacher selected items from the Dollar Store and explains how they can be used for science and art projects and the skills they promote. It shows children doing construction activities and other projects to give you some suggestions about how to use each item.

You may wonder what the difference between STEM and STEAM is. STEM was founded as a fun, hands-on curriculum to attract children to the sciences. Some people thought the artistic side should be included and created STEAM.

Basically, the same thing with art included. So many of these science projects look beautiful and are elementary school art.

The Bottom Line

Educators recognize that when children enjoy lessons, learning is better and lasts longer. STEM toys and kits are designed for just that to attract young children to science, technology engineering, and math.

It’s exactly how the Engino Structures Constructions & Bridges STEM Kit is – my top favorite. Children feel like they are playing, but get the added thrill of actually doing or building something significant. It’s extremely satisfying for teachers and parents to watch children play with these toys.

I hope this article helps you find the one best suited for your students.

  1. Alice

    Thank you for taking the time to research educational aids, especially the ones that use technology. I would never be able to figure it all out without your help. I’m new to STEM and would like to at least modify my curriculum to include as much of it as I can but I don’t have the confidence to choose a kit. Could you please recommend a STEM kit for a beginner? I would like a kit for older students as I teach third grade and they are too advanced for puzzles.

    1. Emily (author)

      I’m happy to help. I recommend two kits that cover chemistry, engineering and electronics. The Playz STEM A+ Chemistry Lab Kit and the Snap Circuits Classic Electronics Exploration Kit. Both of these kits are suitable for third grade and older.

      The Snap Circuits Classic is an award-winning kit that has 60 parts to construct more than 300 electronic projects. Things like a lie detector test, radio and photosensitive electronic organ are just a few of the things that thrill kids while teaching them about how electronics work.

      The A+ Kids Chemistry Set is like a little lab where they can play mad scientist and create chemical reactions to make invisible ink, do magic tricks, make a fire extinguisher and many other things. You never know who is going to consider the chemical construction of the universe fascinating and this kit is a good starting place. They learn about exact measurements, acids and bases and what a chemical reaction is.
