This specially designed workshop focused on the theme of water is aimed at students in the 1st and 2nd grades and includes numerous offerings for conducting 16 experiments. Why are experiments with water a fundamental topic in science education? Every child has already gathered many experiences with water - it is familiar to them. Water is present in and around us: the puddle after the rain, the tea in the morning, cooking and washing, the trees and animals, the climate, our bodies (70% water). Without water, none of this would exist. Goethe already noted: "Everything has emerged from water! Everything is sustained by water!" Water is also an important topic due to its scarcity. Only 3% of the water on Earth is freshwater. Moreover, the question of future energy supply is inextricably linked to water - just think of hydropower plants and dams.
