How it works
What happens at the Koumio® board
Balls (water, carbon dioxide, sunlight, sugar and oxygen) travel a closed run with a hidden lever. The hidden lever does the magic of photosynthesis: sugar is made and oxygen is released.
Once the lever tips, the process is complete. On one side sugar is made, energy for the plant, and on the other oxygen is released for us.
Curiosity questions
Keep going — scan the QR code
Every Koumio® board comes with simple instructions and a closing challenge that leads the child to use what they have just found out. Scanning the QR code opens the solution and follow-up questions.
What children take away
Photosynthesis as a dynamic process, not a picture in a textbook
A feel for what goes into photosynthesis and respiration and what comes out
The principle of a closed cycle in nature, which we are part of
