Week 3 Covid 19 Lockdown.

-
Yay! Team Moana 2020 have just survived their 3rd week of online school and we are all doing great. We have lots of people attending online lessons and Google Hangouts each day and this week our work output went up a notch as what was weird and strange started to feel slightly more normal!
A big thanks needs to go to our whanau who are doing a great job supporting children's learning at home. Thank you all so much, you are being so helpful and showing heaps of Kiwi Can Do attitude.

This morning we had another online science lesson with Miss Fletcher investigating what density is and we carried out an experiment called "Rainbow in a glass."  A few people exhibited exceptional scientific skills and attitudes. Mikayla, Joel, Rory, Max and Ariana showed us patience, perseverance, attention to detail, cleanliness, carefulness and a desire to explore even more during their experiment and, SURPRISE!!! They also had the most successful results. Look below to see a photo of Mikayla's rainbow and Max's salt investigation. We are sure you will agree they have done stunning work.

Max's Salt Experiment

Step 1: Put 1 teaspoon of salt in 30ml of boiling water.
Step 2: Stir to dissolve.
Step 3: Using a teaspoon, put 2 teaspoons of the solution on a piece of black paper.
Step 4: Place piece of paper in the sun.
Result: The water evaporated and the water vapor went into the atmosphere, leaving behind the salt.
  
Salt Farming: Sea water is pumped into a shallow lake.  Warm winds help evaporate the water. The salt forms a crust at the bottom of the lake and the remaining water is then pumped out.
Teacher talk: This result means that when you dissolve salt (which is a solid) in water (a liquid) although the salt and the water now look different, it is only a temporary change. If you leave the mixture alone long enough, the water will evaporate and leave behind the salt in a solid form again. If you had equipment to trap the water vapour as it evaporated, you could collect it and eventually it would cool and turn back into a liquid again. That’s proof that the change was only temporary, because you end up with what you started with.

    Hi my name is Mahina and I am a year 6 at Kawakawa primary school, I like the way you have made this blog post so interesting and how you have told us so much about Max's salt water experiment!
    I think you should name Mikayla's "twin rainbows in a jar" the same as what you have spelt in your writting "Rainbow in a glass", I would like to know how Mikayla made the "Rainbow in a glass" or "Twin rainbows in jar", maybe come and leave a comment on my blog at --> http://kpsmahinak.blogspot.com/

Dubai - SriLanka

Hi everyone, I finally figured out how to access the class Blog so here is my update. I wonder what the temperature is in NZ? It has been 37 most days here, one day even got up to 40🌞 We have been swimming in the Indian Ocean, Persian Gulf and the Bay of Bengal - can you find them on the map? Sri Lanka was a very different place to visit, definitely not a rich country like Dubai, there are a lot of poorer areas, but it has beautiful beaches and the National Parks are great. It is really really sad to see all the forests being cut down though, there have been 35 people killed by elephants already this year as the elephants come down to the people's farms looking for food. There are so many people in Sri Lanka, over 19 million, and their country is smaller than NZ. This made driving on the roads very interesting, there are cars, buses, tuk tuks, motorbikes and bicycles going in all directions. It was like being in a car rally every day! One day we were stopped by a policeman ...

Week 7 Term 1 Cricket Coaching

-
Kia ora 'Yippee!" we all yelled. It was a lovely sunny day at Ohaeawai School and we were all going out onto the field to have lessons in how to play cricket from a couple of professional coaches. They taught us all the basic skills first and then they taught a variation on the traditional game of cricket. This variation makes the game quicker and more exciting for children. We all loved it. Here is a video to show you how it works.

Zoofari

-
Kia ora This week all of the Moana kids who hadn't been on a zoofari trip to Auckland Zoo before, got to participate in one. A zoofari is an overnight trip to Auckland Zoo where you get to sleep in the old elephant house where the elephants Burma and Kashin used to live. You get two guided walks around the zoo, one in daylight and one in the dark accompanied by zoo keepers who know all about the zoo and its animals. You also get some free time to roam the zoo with your teachers and the parents who volunteered to come along. On top of this you get a barbecue dinner and breakfast. Thanks to the generosity of Auckland Zoo, Ritchie's Bus Company and The Warehouse, all of this comes absolutely free! The only cost per kid is $10 to buy lunch and morning tea. So, 45 of us plus Mrs Henderson, Mrs Brajkovich, Mr Solly, Mrs Edge, Mr Palmer and Mrs Chamberlain zoomed down to the big city. We saw so many amazing animals and the whole trip was just marvellous. One of the highlights was...
