Play with water

Have fun with trying out the experiments in your class!

The aim of Play with Water is to develop comprehensive teaching units which should enable primary school children (ISCED 1 Level of Education according to UNESCO) to discover basic concepts of ecology and obtain hands-on experience in cycling of elements in nature, and thus the potential of wastewater as a resource.

Play with Water supplies teachers with experiments that can easily be integrated in their natural science classes. The material is being developed in close cooperation with stakeholders in the field of education. All publicly available material can be found in the «Download» section of this website.
