Week 9 Term 2

Wow! This week we have watched with interest as the seeds have grown within our water cycle terrariums and talked about what we saw. E.g. Tia said “The water evaporated up to the top of the cup. It got stuck, it couldn’t get out and it rained”. Marie said “The soil got hot, water evaporated and it rained – the water got cold on the top.”


This week we have also looked at the Water Aid website. We looked at photos of people who in the past only had access to dirty water but who now have clean water in their villages thanks to the financial assistance of others. We looked at the children who had the job of collecting water and the time it takes for them to collect it – one girl spends 5 hours a day waiting for enough water to seep from the ground.

We can make a difference by helping to collect money to support projects to get water into villages in countries where water is scarce. Next Thursday all the children in the Kowhai team are going to wear blue and bring along a gold coin to place in a wishing well.The money we collect will be given to world vision.

Week 8 Term 2

This week we have worked on our posters – making our message simple and effective.
We have begun to think about where we would like to put our posters, how we can keep them from getting dirty, and who we have to ask to put them up.

On Friday we had a visit from Sally who works for watercare. We had a most enjoyable session with her making water run downhill, building a stream and lake- all by using stones and a sheet of plastic. She also talked to us about how important it is to make sure that only water goes down drains as all the drains lead to the sea.

Week 7 Term 2

This week we have had a look at how precious water is and how vital it is to our everyday lives.





On Friday using the school set of digit camera’s we wandered around the school to take photos we could use next week to make posters about ‘being careful with water.’ The sheer fun of having a camera in our hands resulted in a lot of photos being taken and not all of them involved water!. I’m sure you’re be impressed as all the photos in the bubble share were taken by 5 year olds.

Week 6 Term 2

This week we have looked at books and the metro water website to learn how the water from our dams is cleaned at treatment stations. We found out that aluminium sulphate is added to the water and any dirt clings to the particles of alum. The water is them sent to settling tanks where the dirt and alum form a layer of sludge. This sludge is then drained off.

We made sludge in our classroom using water milo and flour. We sprinkled the milo on the water and then added a layer of flour. The milo clung to the flour and sank to the bottom of the glass. We were fascinated.
