Interactive science expeditions
Science adventures for young explorers.
Every month, one real science mission, for ages 10 and up: program a rocket, decode a signal from Mars, crack a cipher. Coding and tech are just the tools, what your child really builds is the confidence to figure hard things out.
Figure it out, hands on.
Start with the problem
Every challenge is a real problem with the messy details of a real mission. The right questions make your child understand what's going on before writing a line, because here code is a tool for something that matters, not the point.
Scratch Puzzle
The stage separation. Which condition is safe, which one is dangerous?
Which condition safely triggers stage separation, even if the fuel skips past zero?
The finished script appears here once you find the right solution.
Click the correct solution and check if it works.
See it, don't memorise it
Tune the launch angle and watch the rocket arc into orbit. When you can steer it yourself, the maths behind it finally clicks, and code, science and clear reasoning meet in one move.
Concepts you can see and touch
Real concepts, step by step. When an idea is visual and you can play with it, it clicks, and one problem ties coding to a real science. This month physics, next month biology or linguistics.

Thinking as an Adventure
Thinkable is more than a course. It's a space where young minds take on big, messy problems and learn to think with and about the technology they use, not just operate it. Technology is the playground; thinking is the point.
We ask before we tell.
No grades, no single right answer. Pick one and see how a mentor responds.
Explore the curriculumThe rocket must drop its empty first stage. The fuel falls in steps and can skip straight past zero. Which check safely triggers the separation?
Pick an answer — the mentor's reply appears here.
It's a journey, not a list of topics.
The arc of the live Space Expedition. Each stop builds on the one before it.
Program the launch
Variables, loops and conditions become a working rocket algorithm.
Reach orbit
Discover why 7.6 km/s is the number that decides everything.
Decode a Mars image
Turn a real rover photo into data, bit by bit.
Fix the signal
Find and correct errors the way Voyager still does today.
Three expeditions. One way of thinking.
Every expedition is a real-world mission where code, science, and reasoning come together. A new theme arrives each month.
The Cipher
Use algorithms and observation to understand encrypted messages and crack codes.
- Crack historical ciphers
- Think like a codebreaker
- Build your own encryption
Operation Hive
Investigate what threatens our ecosystems and develop data-driven rescue plans for biodiversity.
- Analyse real ecosystem data
- Model what threatens biodiversity
- Design a data-driven rescue plan
One Topic Per Month. One Hour Per Week.
Live sessions and team collaboration are part of the Expedition Crew. Everything else you can also do self-paced as an Explorer.
A new theme every month
Crew & ExplorerEach month unlocks a new interactive mission, designed for about an hour a week. The Space Expedition runs across two: program a rocket launch, then decode a signal from Mars.
Join the live session
Crew onlyOn the four Wednesdays per month from 4:30 to 5:30 PM CET, your child meets a small crew and an experienced mentor online. Small groups mean real attention and room to ask anything, and a mentor is there the moment they get stuck.
Team up between sessions
Crew onlyBetween the live meetings the crew works towards a shared milestone: presenting ideas, comparing approaches, and puzzling things out together, so no one is ever stuck alone.
Build, test and improve
Crew & ExplorerYour child writes code, runs it, and watches it fail before it works, then improves it until it does. Mistakes happen in the open, which is exactly where the learning is, and in the Crew a mentor and crewmates help puzzle them out.
Curiosity as compass
Crew & ExplorerNo grades, no pressure, every child at their own pace. The thinking gets sharper week by week, demanding but never overwhelming, with a mentor right there when it gets hard. Prefer to go solo? Every mission is also self-paced for Explorers.
Thinking that reaches the dinner table
Crew & ExplorerThrough every expedition, parents get the context, discussion topics, and small thinking challenges, so the mission carries on at home as a shared activity, around the dinner table.
More effective, more fun, more confidence.
“My son on the fourth and unfortunately final day of your course: 'Today was seriously the coolest!' Thanks and Congratulations! You are doing something really great here!”
“The best course of all in STEM!!”
— Nick, 7th Grade
“I really enjoyed it! I always found computer science very challenging, but now I see how it connects with other natural sciences and is incredibly diverse.”
— Elisa, 10th Grade
“This is exactly what I imagine teaching material should look like. I can use it in my lessons without a lot of preparation overhead, it's self-explanatory, and the students have fun.”
— Julian, STEM teacher, high school
