How Much Water Do We Use? How Much Water do We Waste?

How much water are we wasting?

Discoveries

We found out that we wast 22 ml of water per minute. It costs $2.24 per cubic metre of water. 950,000 -190-5 days a week for 39 weeks= 25.641025641. Most people use the tap water fountain and can't/won't turn it off. When you leave a tap dripping for 24 hours it will waste 29 litres.

How much water will we probably use this year?

We estimate that this year we will use 950 cubic meters. We may not be using as much as we should be but we don’t know if all this water is being used to its proper usage. Technically we are not using as much as we should, which is 29 - 30 litres for health purposes, such as going to the toilet twice (13 - 13.5 litres a flush ) and drinking 3 litres of water to keep ourselves healthy.

25.9138025095 litres roughly Per student Daily is how much we are using.

Our proposal / recommendation / next steps

• Fix the drinking fountain tap

• Try to turn the drinking fountain which has the tap handle off or not use it at all.
• Don’t wash your hands for longer than a minute.
• Use grey water for the toilets {grey water is when dirty water from taps or household equipment gets used for toilet flushes}
• Collect the rainwater
• Get www.watersaverme for the school

How much do we Use? Statistical Investigation

Statistical Investigation:  How much do we use

At Worser Bay school we have been working on how much we waste as a statistical investigation.

I, Sam  have been working on how much paper we have been wasting we have also found that to make paper you don’t just need trees.

    

Waste of paper

13 pieces of paper per student every day at Worser Bay School.  Is that too much?                

                        By Meg, Emma R, Molly, Betty, Raiha and Hayley

Earlier last year the office printed off newsletters for each family. There are 188 people in our school and the newsletter had 4 pages so 4x188=752. so we now use technology because that wasted too much paper.

• We found out that the school orders 200 boxes of paper per year and in each box there is 5 reams of paper. In each realm there is 500 pieces of paper.

• Adding all those numbers together it is 5x500=2500x200=500,000.
• We wanted to find out how much paper each child uses everyday per year.
• There are 188 kids in our school and 200 school days a year.   
• 500,000 divided by 188=2659 divided by 200=13. So that means we use 13 pieces of paper per student every day at Worser Bay School.  Is that too much?                                                         
• That is at least 17 trees a year used for only 2 photocopiers.

• Trees produce oxygen which makes us breath. Trees are a crucial element in the human life form.
• People need to understand that more than 1 million trees are going to waste just for paper!.
• There should be a limit of paper to use each day. If we reduce this amount of paper we can make a difference.
• Usually people print off a piece of paper to read out in assembly and never use that piece of paper again. But we can reduce this amount by just using our books or technology.                         

• We use 200 boxes each year throughout the whole school. There are 5 reams of paper in each box and 500 pieces of paper in each ream. We found out that there are 500,000 pieces of paper being bought in for the school. We counted how much paper is in all the classes from there work books and there was 26000, 74800 and 76800 paper being used in the classes in books. So 500,000+26000+74800+76800= 677600.

Recommendation

If you usually get a fresh piece of paper STOP because you can just use a scrap or another side of the paper that has been used.                                                                                             

If you draw or write something that you didn’t like or make a mistake don’t just go put it the bin, reuse it.

Encourage your teachers to present more work in digital formats.

Statistical Investigation: How Much Do We Use?

How Much do We Use?

This investigation is looking at how we use resources at Worser Bay School.  We are interested in whether or not we are wasting resources, whether we are becoming more conscious of looking after our environment and whether or not we can do anything to improve the way we use resources.   Everybody is finding information, asking questions, surveying people about their opinions and attitudes so that we can get a full picture of what is happening.  

Investigating the Recyling.  How much paper have we put in the recycling this week?  How was it used?

Some Amazing facts:

• We use about 950,000 litres of water each year
• It takes about 10 litres of water to make one sheet of white A4 paper
• We use about 500,000 sheets of paper each year

We will be sharing some of our results with you next week.
