our biggest challenge

 Here is a writing text using the LEER structure that we did as a class. L- Lead sentence E- Explain E- Example R- Relevance Intro :  Climate change is the biggest challenge of our lifetime. Centuries of pollution and deforestation has led to global warming, rising sea and a plethora of natural disasters. What is it, and what can we do to fix it? Global warming : One measurable aspect of climate change is global warming. Greenhouse gases get trapped in the atmosphere causing the global temperature to rise. Carbon dioxide, methane and nitrous oxide are the 3 main greenhouse gases. Solar energy (heat/light) gets trapped in the atmosphere - this is the natural process of global warming. Humans are making this global warming process worse by emitting lots of greenhouse gases from factories. Global temperatures are rising - causing the melting of glaciers in Antarctica and more natural disasters. IN the 1800’s, humans began the Industrial Revolution, resulting in many factories being built all over the world. These factories emitted carbon dioxide and other greenhouse gases. Humans rely on factories and transport (e.g cars, buses) which all burn fossil fuels. In the last century, the global temperature has risen by 1* C. Deforestation : Another devastating component of climate change is deforestation. There are lots of human actions that are increasing global warming, which needs to be stopped before we get to the point of no return. Deforestation is caused when trees such as confires are milled for temper. When forests are culled less oxygen is produced (as less trees exist) and more carbon dioxide (CO2) is absorbed. This excess CO2 is then released into the atmosphere contributing to the greenhouse effect. A famous example of deforestation is the culling of trees in the Amazon rainforest. The amazon rainforest is the biggest in the world, home to 390 billion trees. People are cutting the native trees to plant palm oil and other food sources. The immediate result of this is that animals' habitat is destroyed. The plight of the orangutan is known around the world. They are a symbol of fighting against climate change. The longer term effect is that certain species have become endangered and even extinct. Damage to the land caused by agriculture is often permanent. Saving the rainforest would help minimise the long term impact of global warming. Agriculture : A third factor contributing to climate change is agriculture. Agriculture is farming with animals. Cows produce a lot of methane through farting and belching which is a greenhouse gas. Agriculture requires huge amounts of land which could be used for forests/rainforests and as habitats for native species. Another damaging part of agriculture is the damage done to local waterways (E.g. rivers and streams) through the fecal matter and urine of those animals. The water gets polluted and fish who live there die. In New Zealand, there are 26.6 million sheep and 10.1 million cattle. If people ate less meat, we wouldn’t need so much land for agriculture and we wouldn’t be damaging local waterways as well. Rising sea : Global warming is causing rising seas through the meeting of Antarctica and the arctic. The largest concentration of ice on Earth is in the arctic (North homisplene) and Antarctica (Southern tomisplene). In these places ice sheets and glaciers hold vast amounts of water. Ice sheets are massive flat platforms that are made on ice, glaciers form over land. Solar energy and greenhouse gases increase global temperatures which leads to these ice from melting, This meltwater causes rising sea levels around the world, leading to increased flooding and coastal erosion. A small island in the pacific which is directly impacted is kiribati. Kiribati is a lowing island experiencing levels of flooding, high tides and coastal erosion. Kiribati is trying to save their island by building new sea levels of coral. Kiribati cities are now becoming climate change refugees seeking asylum in neighbouring couettes such as Australia and New zealand. Kiribati land, culture and native wildlife will be lost forever. While global warming seems like a big problem for the people of Kiribati, it is a matter of life and cleath. Weather/ Natural disasters : The increasing frequency and severity of natural disasters is the direct result of climate change. How to fight climate change : There are many actions that can be taken to reduce the impact of  climate change. Some of these can be done by individual people, such as not using plastic bags, putting your rubbish in the bin and recycling any plastic you use. Actions that every community should take is to have lots of rubbish bin available, plants lots trees and native bushland, use wind farms and solar panels where you can. At a national level, actions New Zealand can take are planting more trees, conservation programmes for native species, introducing laws and policies that limit overfishing and monitoring the deforestation of native timbers. Both individuals and countries should actively be trying to increase the number of bees they have in their land. The biggest change would be if globally, companies stopped burning fossil fuels as this would minimize the greenhouse gases that are entering the atmosphere. One scientific study found that only 100 companies are responsible for 71% of the world's carbon emissions. There are four petrol companies (Exxonmobil, shell, BP and chevron) that are the highest emitters in the world. Another thing consumers can look for is what products they buy - some products use palm oil which is the reason for a lot of deforestation. People should buy palm oil free products. There are lots of ways both individuals, groups and governments can make a difference to reducing climate change. In concussion, climate change is a terrible problem that is the number 1 concern facing our planet. If we do not take the action discussed, within a century our plant will have irreversible damage and our children and grandchildren will not enjoy the world in  the way we did. It is upto every person to make change

Athletics 2020

 So on friday the 13th of november tamaki primary school had athletics in term 4 and there were 4 group and the names are ALAMEIN, TRIPOLI, BENGHAZI, and TOBRUK and all of  those 4 group had to say their house chants around the bike track. As soon all the house chants were done all the houses had to set under the Gazebo and we had to split into our age group and there were 5 different field events and they were high jump, long jump, stand jump, shot put, discus. 


So the first event we did was shot put and after shot put we did standing jump then we did discus and then long jump and after long jump we did high jump. And the teacher who were doing each events were Mr James, Mrs Tefae, Mrs grady, Mr J. but in the standing jump i am last place and in shot put i still came last place and in long jump i came last place but in high jump i still came last place. 


After the 5 events we had morning tea and in morning tea we still try to see who the faster girl or boy in the school but most of the little kid go and play with the form shape and most of the big kids well go and play or run on the track to see who the faster boy in the whole school.

genomics

 

microscope

 

  • Specimens 

  • Slides 

  • Slices

  • Objectives - cost about (300-400) 

  • Stage , clipper 

  • Navigate 

  • Focus knob 

  • Coarse focus knob - move the stage up and down

  • Eyepieces magnify - yellow-100x - bule-400x 



And it start on 4x then 10x then 40x.
