As part of this term’s student inquiry into learning about water, one of the tasks is to identify how much water a student uses in a week. I was interested to see what ideas they’d come up with to measure this. Would you believe it, a simple idea was used by one student. Matte got hold of his household’s water bill and using his mathematics skills worked out on average how much each person it his household used.
There are four people in his house, and combined their daily water use was 460 litres. So Matte worked out the following average water use per person: 460 litres/4= 115 litres. So Matte concluded that he uses on average 115 litres of water per day or 805 litres per week.
Did you know that in a day Matte uses about the same amount of water as 8 full toilet flushes! And in a week Matte uses about the same amount of water to fill four 200 litre rainwater collection containers.
