Last term we were learning about cryptography. If you don't know what cryptography is it is basically hidden messages in things called cyphors. We learned about 9 different cyphors in three different categories easy, normal, and hard. I liked learning about cryptography and some of the cyphers were quite interesting. A site we used to learn about cryptography is dyscover crypt.
This is a slide I made that shows the 9 cyphors that I learned about.
Over the past few weeks we have been working on a thing called arts kete. For this we had to make a poster/clay model about you or your culture. We needed to make these for displays around the school and to show our culture.
For mine I wanted to make the New Zealand flag out of clay. This didn't really work. At first I had to make a rectangle which for some reason was quite challenging. Next I had to put the four stars on. I got about two on it then the next day it was destroyed. So after a few periods of thinking I decided to make a clay model of me like my friends. Unfortunately it fell apart and I couldn't get it to work before we needed to. So I ended up failing because I had nothing to present.
This week we were learning about Live Aid. Live Aid was a concert held in Philadelphia and London to make money for poverty. It was organised by Bob Geldof and Midge Ure.
In the 1970's Bob Geldof was a singer and musician was born in Ireland and was educated at a Catholic private school. He was famous for the single Do They Know It's Christmas. He produced this song with Midge Ure. Bob was mostly involved in the band Boomtown Rats and Live Aid.
In the 1970's Midge Ure was a singer that was in quite a few bands and made a few popular songs. He was famous for the single Do They Know It's Christmas which gave him the motive to organise the event Live Aid. Midge was involved in seven bands. His most famous band being Ultravox.
The song Do They Know Its Christmas was sung by many singers that were famous at the time. This song was made for the Ethiopian kids because people were wondering if they knew it's Christmas. All of the 200 million dollars went to people in Ethiopia. This is what inspired Bob and Midge to do the live aid show.
Over the past few weeks we have been learning about acids and bases. One thing we have been learning about is acid rain. Acid rain is mostly caused by factory's burning fossil fuels. The smoke go's into the clouds and mixes with the water molecules. When it rains it can damage people, builds, plant life, animals and make the water toxic. We done an experiment today on acid rain.
Aim: To observe the effects of acid rain
Hypothesises: I think the petal will dissolve, the calcium carbonate will have no effect, the apple will dissolve, the universal indicator will weaken the acid, I think the bromothymol blue will not do anything.
Method: In petri dish place items around edge. Wet dry ingredients with drop of water. In the middle put a weigh boat
Observations: The universal indicator turned into a pale red because it was an acid. The bromothymol blue turned yellow. The apple did nothing. The petal went lighter. Calcium carbonate kind of bubbled.
This week in social studies we are learning about Woodstock and the Vietnam war. For one of the tasks we had to listen to a song about anti war. The song I am listening to is Give Peace a Chance by John Lennon. It repeats give peace a chance. The song is basically saying to give peace a chance and stop fighting the Vietnamese
This is my reflection for the past few weeks.
We haven't really done anything memorable over the past few weeks at school but we did get a day off last week. But in the weekend I went to the beach. We took some shovels and a wind cart thing that has a sail and gets pushed by the wind. I got the cart quite fast but I only got a few turns because it wasn't that windy. I also dug a really big hole and made a little hill and stated putting water at the top and it made a waterfall. A few weekends ago I went fishing off a wharf thing at diamond harbour. We used squid as bait and I caught a few starfish and threw them back.
I haven't really done much at school but I have done a few things in the weekends.
