A pristine wilderness still exists almost on our doorstep: the approximately 10,000 square kilometre Wadden Sea, one of the world's largest and most important tidal wetland biotopes. Many millions of diatoms, thousands of small crustaceans, many mussels, snails, threadworms and whirlworms live in just 1 square kilometre of mudflats. Huge flocks of migratory birds use the Wadden Sea as a resting and moulting area. Numerous marine fish spend their first year of life, protected from predators, in the warm, nutrient-rich waters of the summer mudflats.

The Wadden Sea Learning Lab opened in March 2014 and offers school classes from the fifth class onwards the opportunity to gain an insight into this unique ecosystem and to explore various topics through independent experimentation.
