This is what we have learnt today for science intensive

Today for science intensive we have learned about water pollution. We watched these videos about what happens when rubbish get deposed to the ocean:

What we have learned:

• We learned that people around the world has nothing to drink, they will drink water that has lots of bad chemical in it.

• Drinking water that was from the sea can make people have diarrhea, really sick and may die.

• When people eat their food and their are finish with the packet they will just chuck it away. The worst things is the wind will blow the rubbish and it will go everywhere especially in the drain, where all the water goes in the ocean.

And this is what we have learned about water pollution today.

Cleaning up my room. So fun

Today I’ve just finish cleaning up my messy room. I looked at my room and it was a mess, I was thinking to myself “Mmm I should clean my room?”, and all of a sudden it was nice and clean. I was happy to see my room nice and clean not messy, also I was happy because I made a huge effort to clean my room.

We have been studying the Treaty of Waitangi. As part of our preparation for our school assembly next week, we have researched people who were at the signing of the treaty. I chose to study Wiremu Hau. I have written a short speech as Wiremu Hau which I will present to our school at assembly.

Kia Ora my name is Wiremu Hau I am a Rangatira (chief) at Waimate in the Bay of Islands. I signed the Treaty of Waitangi on 6 February 1840 at Waitangi. I was baptised in the early 1830s. On 13 July 1844 I wrote to chiefs inviting them to Waimate to discuss the behaviour of Ngāpuhi chief Hōne Heke Pōkai, whose men had recently looted Kororāreka and cut down the flagstaff on Maiki Hill. During the subsequent Northern War, I fought alongside the British at Ōhaeawai in July 1845. I later became an assessor in the Native Land Court. In 1874 My son Hamiora and I we were two of the leading chiefs present when the superintendent of Auckland province visited Mangōnui. According to a newspaper report, I was believed to be one of the oldest chiefs in New Zealand at this time.

Why was the treaty needed?

Why was the treaty needed?

1.The British want our land/ Want NZ

2.Working for more emigrant to come to NZ

3.They want food and house

4.They want the Maori weapons

5.They wanted animals

That all the things that the British wanted from the Maori people after the Treaty was signed. Also the Maori cutted down the flagpole at Russell, 4 years after the treaty was signed.
