Science your 6–11-year-old can play with

Short, ad-free 3D science games in the browser: wire a bulb, put the heart back in place, launch a planet. Here is what your child does, what we collect, and what the plans add.

What your child does here

Every game is a small hands-on lab. A few of the skills the levels practise, in the words of the parent dashboard:

Atom BuilderSnap protons, neutrons and electrons together. Make hydrogen, carbon and neon!
  • Built the smallest atom: one proton in the middle and one electron on the ring.
  • Built helium with 2 protons, 2 neutrons and 2 electrons, and saw its first ring fill up.
Spark WorkshopWire a battery to a bulb. Make it glow!
  • Made a complete circuit: battery, wires and a light (LED) in one loop.
  • Used a switch to open and close a circuit.
Code GardenSnap blocks, move the hero, see real Python!
  • Put coding steps in the right order (sequencing).
  • Used a Repeat loop instead of writing the same step again and again.
Magnet MagicMake magnets push and pull, find north, lift clips and spin a motor!
  • Found out that the same ends of two magnets push apart and different ends pull together.
  • Used a compass needle to find north (and, for older kids, east, south and west).
Float & SinkLet go, change the shape and help a metal hull float.
  • Released a block less dense than water and observed it return to float.
  • Released a denser block and watched it come to rest on the floor.
Body PuzzlePlace organs and key bones in a glowing body puzzle.
  • Placed the heart, lungs and brain and saw breathing and blood flow work together.
  • Put the digestive organs in order and followed food on its trip.
Light TricksBounce a laser off mirrors to hit the star, then see how eyes and ears work.
  • Learned that a mirror bounces light in a new direction.
  • Aimed reflected light downwards by tilting a mirror.
Planet LaunchThrow a planet around the Sun. Too fast? Too slow?
  • Found the launch speed that keeps a planet circling the Sun.
  • Learned that a fast enough planet escapes the Sun’s pull.
Ice, Water, SteamWarm the dots, cool them, squash them. Make ice melt and water boil!
  • Warmed a solid until its particles could slide past each other and it melted.
  • Heated a liquid until its particles flew apart into a gas.
Volcano IslandPush the plates and make a volcano pop.
  • Saw that pushing two pieces of land together builds mountains.
  • Saw that pulling land apart opens a valley.
Fold-a-ShapeFold flat paper into boxes, fill them with cubes and pour cones of water.
  • Folded six flat squares into a box and counted its sides or corners.
  • Picked the flat pattern of squares that really folds into a closed box.
Machine YardPick the right helper and lift the heavy box with a tiny push.
  • Found where to put a lever’s stand so a small push lifts a heavy box.
  • Learned that a small gear turning a big one makes turning easier (but slower).
Moon WatchMake night, make summer, make a full Moon, then hide the Sun!
  • Spun the Earth to see that day and night come from Earth turning.
  • Moved Earth around the Sun and saw summer come when its half leans toward the Sun.
Weather MakersBuild a rainy mountain, grow a cloud and bring a water drop home.
  • Moved water through evaporation, condensation, rain and river flow.
  • Raised a mountain and saw rising air cool enough to make rain.

Safety, in plain words

The same rules as our kids privacy page — and the code enforces them.

  • No ads and no trackers in the kids zone. It loads no third-party scripts, analytics or pixels — a Content-Security-Policy on every kids page enforces it.
  • Children never give us a name, e-mail, photo or location. Play without a kid profile stays on this device.
  • A kid profile holds only an optional nickname you choose, an age band (6–8 or 9–11), an avatar and which levels were completed — never how long anyone plays.
  • No chat, no public profiles, no sharing to social networks.
  • Purchases and settings sit behind a grown-up check. Payments are made by you.
  • You can delete a kid profile and its progress at any time.
  • The grown-up part of the site uses Google Analytics only if you allow it in the cookie banner. The kids zone never does.

The parent dashboard

Behind the grown-up check you see each kid profile’s week: levels and stars, skills practised, levels worth another try and questions to ask at dinner.

Example

Sam · ages 6-8

4 levels this week · 9 stars · Spark Workshop

Skills practised

  • Made a complete circuit: battery, wires and a light (LED) in one loop.
  • Used a switch to open and close a circuit.
  • Lit three lights side by side from one battery.
  • Wired a buzzer so it beeps.

Ask them about…

  • Why does the light only work when the loop is closed?
  • What does a switch actually do to the electricity?
  • How did you get three lights on at once?

Worth another try

Example data — not a real child.

The weekly e-mail (Family and Lifetime)

If you switch it on in the parent zone and confirm your address, you get one short e-mail on Sundays — only in weeks when a kid profile played. One click unsubscribes and deletes the address.

Parent questions

Does my child need an account or an e-mail?

No. Children play without one. If you want progress on every device, you sign in and add kid profiles under your account.

What ages is it for?

The kids zone is made for ages 6–11, with two age bands (6–8 and 9–11). Older children can use the main labs, which go up to high-school and university level.

We have more than one child.

The free and PRO plans keep one kid profile; Family and Lifetime keep up to four, each with its own stars and weekly summary.

How long should they play?

That is your call — we never measure play time. Our parent guide on screen time that teaches has ideas for keeping it short and shared.

What if it isn’t for us?

Cancel anytime in the Paddle customer portal and keep access until the end of the paid period. A full refund is available within 24 hours of a payment.
