Our next statistical investigation was one close to Mr Hogg's heart. Mr Hogg told us about a problem he has with gladwrap around the school. It often blocks the drains up and we have to get plumbers in to find the blockage. It is an expensive problem.
We decided to help Mr Hogg with our mathematical skills. First we put on gloves and got the school rubbish nippers (may not be what they are called). William even had a mask on.
We went around the school and picked up rubbish- even from the garden beds (which we are not usually allowed on but Mr Hogg let us).
Then we sorted all of the rubbish and counted up how many pieces were in each of the categories we had made.
The most rubbish came from wrappers, the second biggest group of rubbish was gladwrap. Maita noticed that most of the rubbish was from lunchboxes. We gave our information to Mr Hogg and we will be working on developing some solutions for him towards the end of the term.
