1. Push taps or twist taps- which saves more water? Lets find out …………. By Miss Guest’s First Class

2. Our experiment: We had the task of finding out which tap- twist or push, was more efficient, i.e. which one used the least water. We had the task of finding out which tap- twist or push, was more efficient, i.e. which one used the least water.

3. What we did : We nominated two people to wash their hands- one using the twist tap and the other using the push tap. We nominated two people to wash their hands- one using the twist tap and the other using the push tap. We collected the water being used in a basin and poured the water from both basins into two separate jars of the same size.

4. Next ……. We drew a line on each jar at the point where the water rose up to. We drew a line on each jar at the point where the water rose up to. There was a BIG difference between the two! There was a BIG difference between the two!

5. For the next five school days … We wrote a tick beside our name on a chart which teacher had made, every time we washed our hands after going to the toilet. We wrote a tick beside our name on a chart which teacher had made, every time we washed our hands after going to the toilet.

6. After the 5 days… Teacher counted up all the times we washed our hands during a school week using our new push taps in the toilet and then multiplied that by the amount of water in the jar from the push tap Teacher counted up all the times we washed our hands during a school week using our new push taps in the toilet and then multiplied that by the amount of water in the jar from the push tap

7. Also… Teacher calculated how much water we would have used if we still had twist taps in the toilets. Teacher calculated how much water we would have used if we still had twist taps in the toilets. We examined the difference between the 2 results. We examined the difference between the 2 results.

8. We discovered….. That each time we washed our hands with a twist tap, it used about 12ml of water. That each time we washed our hands with a twist tap, it used about 12ml of water. Whereas if we still used twist taps, we would use around 90ml of water each time we washed our hands!!! Whereas if we still used twist taps, we would use around 90ml of water each time we washed our hands!!! That’s a BIG difference! That’s a BIG difference!

9. Finally…. We calculated how much water we would save every week by using these fantastic water- saving twist taps. We calculated how much water we would save every week by using these fantastic water- saving twist taps. We discovered that we would save 11.7 litres of water per classroom, PER WEEK! We discovered that we would save 11.7 litres of water per classroom, PER WEEK!

10. This shows how many times we used the push taps in one week- the total was 150 times.

11. Imagine if…. We still were using twist taps and washing our hands that many times in a week! We still were using twist taps and washing our hands that many times in a week! We would be wasting a lot of water so we think that the Push Tap is a clear winner!! We would be wasting a lot of water so we think that the Push Tap is a clear winner!!
