Students Kit Water Purification

With the experiment boxes Water 1 and 2, the pupils get an insight into the cycle of the vital substance water. They recognize the importance of water for our lives, learn where it comes from, how it is distributed as drinking water, then used and ultimately discharged as waste water, treated again and fed back into the cycle.

You will acquire an age-appropriate understanding of the careful use of water as a resource.

• The following experiments are possible with the materials in box 1:
• determine which types of earth hold up or let water through
• find out that a sand and gravel filter holds back solid components, while dissolved substances (oil, salt, detergent) cannot be removed from the water by filtration
• recognize the impact of polluted water on germinating plants
• understand the stages of mechanical water purification
• discover the principle of communicating vessels and transfer its applications
