This challenge had several different aspects to it. We set up the homemade rain gauges in the garden by the Grade 6 classes, and checked them for the two weeks. Unfortunately, this was during a rather dry patch, so there wasn’t much rain recorded.
Then we had the challenge of measuring the roofs of the school, which was very difficult, seeing that most buildings are double storey, and we can’t even see the roof of the new hall because of the lie of the land.
We had to estimate, and came up with a plan diagram of it. Then I had the Grade 5 maths class help me with the calculations. They were quite horrified at the formula to calculate the area of a trapezium!
The final bog section of the challenge was the collage of how other countries collect rainwater. We had our Grade four group work at that, and they did an amazing job. Those posters were displayed on our Media Centre notice boards for the school to see, and we put them on our Facebook page so that the parents could have a look as well.
We are working at getting another JoJo tank for our Grade R building using some of our prize money from last year.
