Water Detectives!

On Wednesday morning our eager 2KR Detectives reported for duty, ready to complete a very important mission! They had to investigate how much water we use when we brush our teeth. First, each Detective had to predict how much water they thought would be used, when the water was left running for the whole two minutes of brushing time. They were all extremely surprised that a lot more water was used than they predicted and we needed to use a second two litre bottle!  If you look at the first picture in the photos below, you can see how much water we actually used. It’s significantly more than the amount of water that was used when we turned the tap off in between rinsing, as you can see in the second photo. We also discussed how much toothpaste we should use and we decided that we should stick to the recommended ‘pea sized’ amount, so we don’t have to use too much water to rinse our mouths. Will you turn the tap off next time when you’re brushing your teeth? We certainly will!

After the experiment, we all had a go at being water wise teeth brushers and completed a report for our bosses, Detectives Koudmani and Robertson. Mission accomplished!
