As you may remember, on the 27th of july we collected data of the rubbish distribution around Waimairi School before and after lunchtime.We recorded this data on a map of the school and made observations of where all the rubbish was accumulating. We also made inferences about how the rubbish got there.
After we made our observations and inferences, we were left with questions as to why people in our school failed to put their rubbish in the bins! Why does so much end up back around the school after one break time? Maybe it is falling out of people's pockets? Perhaps it's the winds fault? Or maybe the students of Waimairi school are dropping it on purpose?
We, as scientists, have completed an investigation into why this is happening. On Thursday the 18th of August, we went out at morning tea and lunchtime to make observations of you all, collecting data to find out how rubbish gets on the ground.
We split up into 12 groups. At morning tea we spread ourselves around the whole school to observe. At lunchtime we spread the 12 groups around the lunch eating areas and observed what happened to the rubbish.
We have made inferences from our observation and here is what we have found…
Our observations and inferences: (Please answer these questions in full sentences for your presentation to another class)
On Thursday 18th of July at morning tea waimairi school dropped 205 pieces of rubbish, that's 2 out of 5 people on average, who dropped rubbish.110 pieces of rubbish were dropped on purpose, and 46 pieces of rubbish were dropped without realising!
We think that most people did this because people think that they can hide it, or get away with dropping it. And they do get away with it! Why don't people take a little walk over to the bin to put their rubbish in?
At lunch time 79 pieces of rubbish were dropped on purpose, and 44 was left where they were eating, that's 1 out of every 5 people in the school, that is a large amount of people to be dropping rubbish This is rather astounding, because even at lunch time when you were sitting down waiting for the bell to ring you managed to get away with dropping the rubbish. Also leaving rubbish were they were eating was quite popular. This disgusted us. We're they put it is yet another mystery. Still unanswered.
