15 STEM Gifts for Tweens

Sharing is caring!

Good STEM gifts for tweens don’t look like homework, because no tween on earth wants a present that smells like school. If they like building, puzzles, weaving or poking at things to see how they work, you’re already halfway there.

A circuit kit and a loom are two very different presents, and they both count. Start with what they like to do, then check what the kit needs. Got more people on your list? Here are my gift ideas for everyone.

Fair warning, this list has a rattlesnake you get to cut open and a rock tumbler that runs for days. If you’re buying for somebody else’s kid, you might want to warn the parents.

Puzzle and Pattern STEM Gifts for Tweens

Choose the Kind of Project Before the Kit

For a tween who likes building, compare how the pieces work. SparkBlocks focuses on circuits. Clixo uses flexible magnetic pieces, while Gravity Maze asks the player to work out a path for a marble. These are different activities, even though they all sit comfortably in a STEM guide.

We'll email this post to you, so you can come back to it later! You'll also get regular recipes & printables to your inbox!

Weaving is another direction. The Weave-n-Wonder kit gives a project to make with yarn rather than electronics. Choose it for an interest in making things with patterns, without promising that every tween will prefer a craft to a building kit.

Check Screens, Supplies, and Age Guidance

SparkBlocks is listed here as a screen-free option. The Thames and Kosmos robotics kit uses an app. That distinction is worth checking with the family before choosing, especially if the gift needs to work without access to a compatible device.

Not every item in this roundup has the same intended age range. The Sunny Auntie magnetic tiles are listed for ages 4 to 8 and run younger than the rest of the guide. Do not use the word tween as a substitute for reading each manufacturer’s age guidance and instructions.

Check what else is needed before wrapping the present. The Sunny Auntie light-up tiles require batteries that are not included. For any kit, read the instructions and equipment list so the recipient does not discover an extra shopping trip between opening the box and starting the project.

❓ Frequently Asked Questions

Before you wrap that circuit kit, here’s what to check.

Start with the activity the tween enjoys, then check the kit’s age and skill guidance. Compare circuits, magnetic building, weaving, or observation rather than assuming every STEM kit offers the same experience.

Read the manufacturer’s instructions, warnings, and supervision requirements before choosing a kit. Check the specific listing for supplies or equipment that are not included.

Choose a kit with instructions and an activity that match the tween’s current experience. Check whether an adult will need to help and whether the family has the time and supplies for that project.
