A lot of parents who write to us aren’t really asking “which robot is coolest?” They’re asking a quieter question: after school, or on a wet Saturday in November, what can my kid do with their hands that isn’t another hour of YouTube?
A STEM kit is not a treatment for screen time, and we won’t pretend the research says otherwise. What a good kit can do is fill the slot that would otherwise go to passive scrolling — the same kind of offline play, making and experimenting that Canadian paediatric guidance already asks families to protect.
You can browse the kits we actually sell in our Science & STEM Kits collection or on the Science & STEM kits page. Below is how they line up with that goal, including the honest part: some of our kits are fully screen-free, and some use a phone or a computer after (or during) the build.
What Canadian paediatric guidance actually says
The Canadian Paediatric Society’s 2022 statement on screen time and preschool children still uses four principles: minimize, mitigate, use screens mindfully, and model healthy use. For children younger than 2, it does not recommend screen time apart from video-chatting with caring adults. For children 2 to 5, it recommends limiting routine or sedentary screen time to about 1 hour or less per day. It also asks families to keep daily screen-free times — especially meals and book-sharing — and to avoid screens for at least 1 hour before bedtime.
That preschool statement is blunt about the trade-off: “Too much screen time means lost opportunities for teaching and learning.” It encourages adults to join children in activities unrelated to screens, and it names shared reading, outdoor play, easy board games and crafts as examples.
For school-aged children and teens, the CPS takes a slightly different angle. Its 2019 statement on digital media (reaffirmed July 4, 2025) asks families to remember four “Ms”: manage screen use with a family media plan and clear limits; choose meaningful screen use — educational, active or social, rather than passive or solitary; model healthy habits, including daily screen-free times and no screens for at least an hour before bed; and monitor for signs that screens are crowding out sleep, school, face-to-face time or offline play.
Separately, the Canadian 24-Hour Movement Guidelines, summarized on the CPS site for children 5 to 11 and adolescents 12 to 17, recommend limiting recreational screen time to no more than 2 hours a day.
None of that is an argument that every minute off a tablet must be spent with a science kit. It is an argument for having something ready that occupies attention in the real world — and for being honest about when a kit quietly pulls a phone back into the activity.
Why a hands-on kit can help (without overselling it)
When a child is brushing dust off a fossil, snapping a circuit or rebuilding a solar robot in the backyard, they are not passively watching a feed. They have a next step, a problem to solve and a result they can hold. That matches what the CPS is protecting: teaching, learning, play and family time that screens often displace.
It also matches how a family media plan actually works in a house. Limits are easier to keep when “we’re done with the tablet” has a landing place — a brick to excavate, a volcano to fizz, a robot to finish — instead of a blank afternoon.
What we will not claim: that our kits have been clinically shown to cut screen time by a set number of minutes, raise grades or fix sleep. Those studies are not on our product pages, so they don’t belong in this article.
Kits that are screen-free from the first step
Several listings in our collection describe work you do with your hands, not with an app.
The Electronics Science Kit, listed for ages 5 to 12, is snap-together circuits on a base grid: 32 parts, 448-plus projects, no soldering and no extra tools. The live product page itself calls this out as “screen-free fun” and says hands-on building keeps kids focused and learning without screens. That’s the listing’s description, not a research finding — but it is an accurate picture of the activity. Lights, sounds, a mini vacuum, an RGB module and flying-saucer accessories all happen on the grid in front of them.
The Fossil Dig Kit 3-Pack is three complete excavations. Kids chip, brush and dig to uncover a dinosaur fossil replica. The page calls it a screen-free afternoon and notes that three kits mean siblings or friends can dig at the same time. The listing includes 90-day returns and a 3-year warranty.
The 2-Pack Kids Science Lab Kit is 70 experiments per kit — volcano eruptions, colour-changing reactions, crystal growing and more — with an illustrated guide. Adult supervision is recommended. No screen is required to run the experiments. The listing includes 90-day returns and a 3-year warranty.
The 12-in-1 solar robot building kit 4-pack adds something the indoor kits can’t: you build the robot, take it into the sunlight and watch it move. No batteries needed. Four complete kits means a sibling group or a classroom table can work at once, or one builder can keep a small fleet. That’s hands-on time that can also be outdoor time — another thing paediatric guidance asks families to protect.
A solderless breadboard kit is the same idea for an older student: circuits you can change in seconds, without an app and without a soldering iron.
Kits that use a screen for part of the experience
Some kits are still a hands-on build first, then they meet a phone or a computer. That’s not a reason to avoid them. It is a reason to decide, ahead of time, how the screen part will work in your house.
The 5-in-1 STEM Remote Control Robot Building Kit, listed for ages 8 to 13, is a 494-piece build before anything turns on. Kids can drive it with the 2.4 GHz remote — no app required for that part — or use the smartphone app to code moves. The listing describes a 400 mAh rechargeable battery and about 40 minutes of play. If your goal is less passive screen time, you can treat the app as optional and start with the remote. If you do open the app, that is closer to what the CPS calls meaningful screen use: educational and active, not another video autoplaying in the background.
The DIY Wireless Speaker Building Kit is listed for kids and teens. The build uses wood panels, two drivers, a circuit board, wires, screws and a screwdriver, with an illustrated guide and no experience required. Playing music afterward means pairing the speaker with a phone or other device. The making is offline; the using can go either way, depending on what they play through it.
The 90mm astronomy refractor telescope is listed for adults and beginners. Looking at the Moon’s craters and seas, or using it for birdwatching and night-sky exploring, does not require a phone. A phone adapter is included if you want to take a photo of what you see. The viewing itself is outdoors, after dark, which is about as far from a bedroom tablet as a family activity gets. The CPS specifically asks families to keep recreational screens out of bedrooms and to avoid screens in the hour before bed — so if you take the telescope out after supper, leave the phones in the house unless you’re using that adapter on purpose.
Teen maker kits sit in a third category. The Ultimate Teen Arduino Maker Kit and the development boards that work with the Arduino IDE involve a computer because that’s how you write and upload code. The CPS school-age statement asks parents to prioritize screen activities that are educational over ones that are passive. Writing a program that turns on an LED is a different kind of screen time than watching short videos until bedtime. It still counts as screen time. It also teaches something you can point to.
How to use a kit as part of a family media plan
The CPS asks every family to make a media plan — when screens are allowed, when they aren’t, and what counts as meaningful use. A STEM kit fits that plan more naturally if you decide a few things up front:
- Give the kit its own time of day. After school, before supper, or a stretch of Saturday morning works better than “when the tablet dies.”
- Protect the hour before bed. A fossil dig or a science experiment can run earlier in the evening. Save the speaker’s playlist and the robot’s app for earlier too.
- Sit down for the first session. The science lab recommends adult supervision. The robot has 494 pieces. Even screen-free kits go better when someone is there to read the next step.
- Be clear about the phone’s job. If the robot app or the speaker pairing comes out, say so: “the phone is for coding this move” or “the phone is for playing the song,” not “the phone is back on the table.”
- Keep it a shared activity when you can. The CPS prefers family time and co-use over a child disappearing alone with a device. Building a circuit or taking a telescope onto the deck is easy to do together.

FAQ
Can a STEM kit replace screen-time limits? No. Limits, sleep, meals and face-to-face time still come first — that’s the CPS guidance, not a store slogan. A kit gives your child something worthwhile to do inside those limits.
Which of your kits are actually screen-free? The electronics science kit is described on its own page as screen-free. The fossil dig 3-pack, the kids science lab 2-pack, the solar robot 4-pack and the solderless breadboard kit are hands-on activities that do not require a phone or an app to work.
What if the kit uses an app? The 5-in-1 robot can be driven with its remote without opening the app. The wireless speaker needs a phone (or another device) to play music after you build it. Teen electronics kits that use the Arduino IDE need a computer. In CPS terms, those are closer to educational or active screen use than to passive viewing — as long as they don’t take over the evening.
Is this appropriate for a preschooler? The electronics kit is listed for ages 5 to 12. The robot is listed for ages 8 to 13. We don’t print a numeric age on the fossil dig or science lab. For children under 5, follow the CPS preschool guidance first: very little sedentary screen time, screen-free meals, and no screens in the hour before bed. A science activity for that age only makes sense with an adult right there, and only if the product page’s supervision notes fit your child.
