A Successful Science Experiment.

-
What a busy term it has been and it's already the end of Week 5. Team Moana have been really busy getting their heads around our science unit based on the classification of life forms. We learned that living things all carry out seven processes and that you can remember them by using the acronym MRS GREN. This stands for Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion and Nutrition.

We decided to do an experiment to see if plants really do respire. The scientists say that plants take carbon dioxide from the air, use it inside their cells to grow, and release some oxygen back into the air as they don't need all of it.

We tested this hypothesis by putting leaves in warm water for a few hours. If it was true, we should see little bubbles of oxygen forming on the surface of the leaves. It worked!!!! It was very cool!!
Ariana took this very good photo using an iPad so now we have proof that our experiment worked. We don't know why the bubbles are only on one half of the leaf. That might need some more investigation.

    Kia ora Team Moana my name is Honekai. I go to Kawakawa primary school. I am a year 8 in Nga Rau Rangatira. It is really awesome to see that you guys are learning about science on plants. Also really interesting that the bubbles only go on one side of the leaf. Maybe next time you could do steps on how you did it. So my class can follow.

    Guten Tag Team Moana! My name is Mase from Kawakawa Primary School. I'll have to say, this is a very interesting post about science. I hadn't known that plants take carbon dioxide in their cells and produce little oxygen bubbles. Overall, I really do enjoy this post and it's got me thinking quite a bit about how biology really works. Anyway, Thanks for reading and I'll blog ya later!

    Hi Team Moana my name is Braxton and I am from Kawakawa Primary.
    I really liked reading this blog post because I never knew you could see little oxygen bubbles coming out of leaves that is so cool.
    I was wondering how do you guys come up with this it was very interesting.
    If you guys have any spare time come check me out at https://kpsbraxtonleer.blogspot.com/ but until then bye.

    Hi Team Moana
    You have been working really hard in science I liked the experiment you completed. I am really impressed that you learnt the acronym MRS GREN I learnt about MRS GREN when I did biology at college.
    Keep up the good work.

    Kia ora team Moana my name is Ngapua and I go to Kawakawa primary school. I really liked reading how you get to use carbon dioxide its very inspiring,I love how you got proof to show that its real,I hope one day our class can do this experience. I hope you can figure out why there´s only bubbles on one half of the leaf.

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 ...

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...

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.
