Knowledge can also be fun. Along the topic of water, Leonhardt has developed a new website for children and teenagers, set up a content management system and implemented several topics.
One goal of klassewasser.de is to support the curriculum in schools. Many issues, in parts quite complex, have been processed in a vivid way. For example, the path water takes through a city: from the source through the treatment and sewerage into the households, and back to nature via sewage drains and treatment plants.
On the other hand, there is no missing out on entertainment and recreation value. In case you always wanted to know the equivalent of "I bathe until I'm shriveled up" in other languages, you can read and even listen to the according translations. Games and audio books for long rainy days, indoor experiments related to water and lots of recreational tips along the topic of water are also available.
For teachers and educators, a separate area has been set up which provides information on training as well as teaching material. This area also offers the opportunity to sign up for tours and excursions.
