Storm Water Sleuthing - Data Collecting, Mapping & Extrapolation

 





Our citizen science stormwater project continued today with the Eco Warriors and Monique. We split into groups to map the outdoor drains and survey the litter in our drain trap. 

It took a long time to carefully sort and weigh the litter in the drain.

In May there were 30 pieces of litter in the drain. Today there were sadly still 34 pieces. The bits of Tiger Turf in the drain are also a problem, but we didn't count these.

 Straw wrappers, Tiger Turf, and food wrappers were the biggest problems. A reminder that we need more litter-free lunches, please.

Next, we extrapolated that if there are 27 drains and 64 pieces of litter in each drain there could be 1728 pieces of litter leaving Wakaaranga and going into the Wakaaranga Creek every few months.  Oh no! What could we do? Jiajia - reward litter-free lunches, Lily - pick up litter, Kelly - take your litter home.  

Do people know that outside drains go to the sea? Are they dropping the litter by accident? 

How can we draw attention to this problem? Samuel - give rewards for litter-free lunches. Esther - spread awareness by talking in an assembly. Jiajia - a class activity to acknowledge litter-free lunches.  Indi - litter-free lunches go to morning tea early. Charlotte - make posters.

Next time we are going on a field trip to the creek to see where our stormwater leads ...
