Today, Year Six learnt about how our local estuary and wetlands protect us from flooding. First we discussed our experiences of heavy rain and flooding and read a slide show from DOC.
We conducted an experiment in the Mara Kai, which showed how much faster rain water flows over concrete than natural surfaces.
Then, we watched a video about how cities around the worldand especially in China, drained their wetlands, and are now spending billions to put them back in as sponge cities. Lucky we never drained the Wakaaranga Creek!
Lastly we played Niwa Flood Challenge Game to learn how to make good choices as a home owner and community member in a future where flood events are getting for frequent.
What did you learn?
Lucy "Don't buy next to a river and if you do make changes so floods won't hit it. Always look at the flood maps before you buy a house".
"Sponge Cities are human made to work like estuaries and wetlands to stop flooding" Renee
"Wetlands stop chemicals going into the sea" Brayden
"Don't drain wetlands to build houses" Alysia
"When I buy a house I won't buy next to a river" Angela
"Buy a house near grass and trees so the rain gets absorbed" Haniya
"Buy a house on top of a hill" Grace
"Don't live near water" Aileen
"Use your money wisely"
"Plant trees and build stop banks to protect against floods" Kaiden
Next time we'll look at the animals that live in our local estuary.
