When a heartbeat raises questions

During lunch, a child suddenly discovered his own heartbeat. A spontaneous moment that led to a little journey of discovery through the human body.

A simple observation gave rise to genuine amazement, accompanied by many curious questions. Together we searched for answers, felt our pulses and began to understand how the heart and body work together.

A movement game demonstrated the circulatory system in action, with the children acting as little ‘drops of blood’. They delivered red, oxygen-rich blood cells to different parts of the body (brain, arms, stomach, legs, etc.) and took blue, oxygen-depleted blood cells with them on their journey through the circulatory system. Back at the heart, the blood went to the lungs, where gas exchange took place, and the cycle began again.

Children learn most deeply when they are intrinsically motivated and when they experience, feel and move. Active physical experiences create new connections between nerve cells in the brain.
These synapses link sensory impressions, movement and emotion. In this way, knowledge is not only absorbed but also anchored in the memory.


My job as a professional is not to teach children. My job is to create space for them so that they can independently learn about the world, their bodies and life.

Because our future lies in their curiosity, their wonder and their questions.
