Clean Water, Games

Water Friendly City

Today we will combine knowledge about sustainable cities and water retention. Listen to “I love my city, I save water” fairy tale and try to memorize what message the trees were trying to pass to Mr. Teacher. What did eco detectives discover when wandering around Poland? 

Instruction

Look at the city board in front of you. Can you name the city elements shown in the illustration? (Children list a block, a single-family house, a grassy hill, a street, grass, a playground as well as sewer and drainpipes.)

Please tell me, in which of these places water have a chance to settle? Where can rain soak into the soil? I’ll give you a hint – these places are marked with the most blue dots. (Answer: on a hill, on a lawn, next to the tree). What are the places, where the rainwater is drained from the city directly into the pipes and through the pipes to the river and further to the sea? (From the street, sidewalk, house, block, playground). Are there more places in such a city, where the water stays in the soil or where the water is piped to the river?

And now, randomly select items I have prepared for you. Each of them helps retain water in the soil. Tell how the object or place you selected, facilitates water retention (i.e., water storage).

Conclusions

Everyone would like to live in a green city – full of parks, gardens and flower meadows. In a city where, thanks to trees and vertical gardens (i.e., vertical, such as ivy on the facade), temperatures are much lower than in unfriendly, concrete cities. Human and eco-friendly cities need plenty of places where water can be saved. Instead of lawns, we need flower meadows – they dry out much more slowly, with less evaporation. Instead of playgrounds paved with cobblestones, we need playgrounds with green rows of trees and bushes. We must collect rainwater in aboveground or underground containers to use when it does not rain. We should plan building roofs in a way that they could bear the weight of roof gardens. We should design our cities to preserve water everywhere like in small hollows and ponds helping give life to many species of plants and animals.
