8 Best STEM Toys of 2026

Ozo at Home is Ozobot's kit built for parents rather than teachers, and it is the clearest path on this list from screen-free play to real code. The box holds one Ozobot robot, a two-sided Magnetic Board with a Mystical Forest mat on one side and a blank side for building paths, Color Code Markers, Color Code Magnets, a Get Started Guide and a charging cable. Children begin by watching the robot follow lines and read color codes that change its speed and direction, then draw their own codes, then move to Ozobot Blockly to program dances, loops and light shows. The last stage adds engineering: kids build cargo holders, shelters and bridges and revise them until the robot succeeds. Ozobot counts 27 activities in sequence, many lasting 10 to 30 minutes, so they fit a homeschool block or a weekend. At $99 it costs less than every other robot here. The limits are a single robot, a computer or tablet for the Blockly stage, and a grade label of K to 5 instead of an age range.

KiwiCo Tinker Crate is the science and engineering line of KiwiCo's subscription boxes, aimed at ages 9 to 12. Each month brings one build with instructions, ways to play and bonus challenges, plus videos and activity ideas online. KiwiCo's current examples are a Mega Hand with jointed fingers that moves when you gesture, a Delivery Bot radio-controlled robot and a Bottle Rocket Blaster that uses chemistry for launch. KiwiCo describes its projects as low threshold, high ceiling: quick to start, with room to go further. The regular price is $30 per crate, and KiwiCo advertised a code that brings the first crates as low as $19.20 when we checked. Members get free shipping on any U.S. order and 10% off every order, and the plan can be switched or cancelled anytime. The trade-offs are cost over a year and the format itself: each crate is one finished project, not a toy that grows like a robot, and there is no coding.

Makeblock mBot2 is the most engineering-heavy toy on this list. It comes as a kit: the CyberPi main controller, an mBot2 Shield, an ultrasonic sensor, a quad RGB sensor, encoder motors, a chassis, wheels, a screwdriver and a line-following track. Children build the robot, then program it in block code and move to Python in the same mBlock software, and CyberPi also supports the Arduino IDE for C and C++. The built-in 2500 mAh battery gives about 5 hours of play and charges in an hour over USB. Bluetooth and Wi-Fi let one mBot2 pass instructions to another, and up to 10 mBuild modules can be chained on. Makeblock adds 8+ free basic courses and 24+ free learning cases with step-by-step guides. At $149.99 on sale from $177.99 it costs more than Ozo at Home, and the build is a real project that younger children will need help with. Makeblock also notes it ships only to the contiguous United States.

The Osmo Coding Starter Kit turns a tablet into a coding game that children control with real blocks on the table. The kit includes 31 coding blocks, the Osmo Base and reflector, and three games. Coding Awbie has 35+ levels of sequencing a character through forests to a volcano, Coding Jam uses loops and patterns to compose music, and Coding Duo sets side-by-side puzzles that two players can solve together. The iPad camera reads the blocks through the reflector, so children snap code together by hand and see it run on screen. Osmo says it works with most iPads on iPadOS 15 or later, needs no Wi-Fi and has no subscription. The regular price is $119.99, and it was on sale for $90.00 when we checked. It is the easiest start on this list for a 5-year-old, but it teaches coding only, with no physical robot or engineering build, and it needs a tablet you already own.

Snap Circuits Jr. SC-100 is the electronics pick. Elenco's kits use components mounted on snap connectors, so children build working circuits by pressing parts onto a grid and following the colorful pictures in the manual. Elenco calls Junior its best-selling model and says Snap Circuits are the only circuit-building toys that use CircuitSafe Fuse Technology, patented for safety. The lesson here is electricity itself: how a switch closes a circuit, what makes a light or a motor run, and why a fuse matters. When a child outgrows Junior, the line steps up to Classic SC-300, Pro SC-500 and Extreme SC-750, and spin-offs such as Green Energy and MyHome Plus cover renewable power and home wiring. We ranked it on documented features only. Elenco's online store blocked our requests, so we could not record a verified USD price, and its public pages list fewer specs than the other makers here.

Chem C1000 v2.1 is the chemistry pick and the only kit here that is about science rather than coding or robots. Thames & Kosmos lists 125 experiments with real chemicals, guided by an 80-page manual written by educators and scientists. Children set up a lab space, learn about indicators with litmus solution, write invisible-ink messages, investigate iron, copper and carbon dioxide, split water by electrolysis and try kitchen chemistry with sugar, eggs and fatty acids. The set has a long award history, including a 2004 Parents' Choice Gold Award. At $59.95 it is the lowest one-time price on this list, and Thames & Kosmos ships free on orders of $50 or more. The trade-offs come from the subject: the age rating is 10 and up, real chemicals mean an adult should supervise, and it needs table space that can get messy. The product page also notes it is not for sale in Canada.

Sphero BOLT is a clear robot ball, 2.87 inches across, with motors, sensors and a programmable 8x8 LED matrix inside. Children code it three ways in the free Sphero Edu app: drawing a path on screen, dragging blocks, or writing JavaScript or Python, so the same robot serves a beginner and a teenager. Sphero describes the shell as durable and waterproof and the battery as lasting all day, and it charges on an inductive base. The box also includes a 360-degree protractor, stickers and a quick start guide. Sphero Edu runs on Chrome, Mac, PC, iOS, Android and Kindle, and the Sphero Play app adds Block Drive for home play. Sphero lists 1000s of activities. At $179 it is one of the pricier picks, and the product page now flags a newer BOLT+. Every activity needs a device, so it is the least screen-free robot here.

Dash is Wonder Workshop's programmable robot, now sold by MORAVIA Education, which acquired Wonder Workshop's assets. It arrives assembled and charged, and children aged 6 to 11 program it in free apps such as Blockly and Wonder to move, sing, dance, flash its lights, respond to voices and tell stories. The maker lists the concepts covered as sequencing, events, loops, algorithms, operations and variables. Dash has no camera; sensors let it detect obstacles and sounds. A full charge gives about 5 hours of active play and recharging takes under an hour. Once the apps are on an iPad or Android device, no internet connection is needed. The box holds the robot, a USB charging cord and two building brick connectors. At $189.99 it is the most expensive single robot here, accessories such as the Launcher ($34.99), Sketch Kit ($44.99) and Gripper ($44.99) add more, and the battery cannot be replaced by the owner.
