What's Inside a Computer? 

For last two lessons we pulled apart a old laptop for research. We looked at all the different parts of the computer. We had to rip the mother bored to get under it. we pulled the screen apart and looked at the liquid crystal and we torched it. we looked at all the things on the mother bored.         

I learnt there is liquid crystal in a computer screen

OVERARCHING QUESTION

pH and ocean acidification

The world’s oceans currently absorb as much as one-third of all CO2 emissions in our atmosphere. This causes the pH to decrease, resulting in the ocean becoming more acidic. This could have significant impacts on life in the sea. It is difficult to predict the overall impact on the marine ecosystem, but many scientists fear that ocean acidification has the potential to decrease marine biodiversity on a very large scale.

Is there anything we can do to reduce ocean acidification?

In order to cope and be resilient as best we can with climate change humans need to be able to adapt our lifestyles, thinking and perhaps values. We need to think about and act on ways to mitigate (reduce, lessen, alleviate) consequences of global warming, such as climate change, and adapt to current and predicted effects. Central government, local government, business and all citizens (households) are stakeholders in making these changes.

As a group discuss your evidence and brainstorm ways we could adapt and mitigate against the effects of global warming and climate change.

For each stakeholder group think about what action could be taken to mitigate and adapt to the expected effects.

Stakeholder	Ways they could mitigate ocean acidification
Central government	Could change the way we use energy, instead of using cole/fossil fuels use wind power or solar power. - By banding types of cars that are using to much petrol, and adding more busses for transport around town etc.
Local government	Have a day of when everyone from town cleans up a part of town, beach etc.
Business	Have a day where people can go to schools and take kids to help tidy the town, a park etc. You could also teach the kids why we are doing it and how its affecting the environment, by showing them/ taking them on walks in a park and show how it has changed over the years.
Citizens/households	Use fabric bags instead of getting plastic bags every time we go to the supermarket. Ior by trying to go trash free.

Ocean Acidification

The gas that was produced in both the aspirin and the dry ice experiments, was carbon dioxide. This is a naturally occurring gas that is present in our atmosphere. The following links are to news articles about the link between rising carbon dioxide levels (due to made-man pollution), and ocean acidification. I’d like you to understand what acidification is, how it occurs, and the effects it is likely to have on our planet.

Open the links and have a quick skim read of them. You do not have to read everything, but at least quickly go through, look at any images or diagrams, and pick out some keywords so that you get what the article is trying to say. If you don’t cope with too much reading, or the articles are confusing for you (I have tried to include some easier ones, marked with a *), then look at the infographics instead. Same info, just in pictures!

Questions  type your answers under the questions

• How have humans contributed to ocean acidification?

By putting more carbon dioxide in the air

• How is ocean acidification affecting organisms in the ocean?

Bleaching good coral

• Why is the rate of ocean acidification alarming to scientists?

The temperatures are rising

• What can you do to reduce the effects of ocean acidification?

Not drive our cars to often or share cars

• Find a suitable line graph from a source NOT listed here, that shows ocean acidification over time. You MUST be able to understand it yourself! The graph should be simple enough for everyone in the class to understand.  Copy and paste it here.

• You can do this task in a group of 2 or 3 if you like. Everyone must have it written down though.
  How could we do an experiment in our classroom that investigates the effects of acidity on shellfish and coral? (Hint: both are made from calcium carbonate, what could we use to model/instead of their shells? Google!)

Design a small experiment that would give use more evidence for the dangers of ocean acidification on these animals. What would you need, what would you do, and what would any results tell you? (I will pick a few of the best explained experiments for us to actually do in class)  You can include images if you like.

Experiment is in Jess's book

What is an acid?
a substance with particular chemical properties including turning litmus red, neutralizing alkalis, and dissolving some metals; typically, a corrosive or sour-tasting liquid of this kind.
What is a base?
In chemistry, bases are substances that, in aqueous solution, are slippery to the touch, taste astringent, change the color of indicators, react with acids to form salts
What is pH and how do you measure it?
pH meter 
What is neutralisation?
When an alkali is added to an acid, the pH of the mixture rises as the alkali reacts with it forming neutral products. ... A reaction in which acidity or alkalinity is removed is called neutralisation. A neutralisation involving an acid and a base (or alkali) alwaysproduces salt and water (and nothing else).

2017 Year 10 Written Text Assessment on ‘The Outsiders’

In The Outsiders by S.E Hinton dialogue was used to show how ponyboy’s thoughts. We see this when Macia and Ponyboy are outside the drivin and Macia was asking about darry and Ponyboy say “He doesn’t care about me”. This makes the audience feel sad for Ponyboy thinking darry doesn't care about him. He thinks he only cares about himself and Sodapop. This reminds me of the story On The Sidewalk Bleeding when the couple see him a know he's injured but don't do anything because they are scared of the other gang.  

In The Outsiders By S.E Hinton  actions were used to show dallys sadness. We see this just after Johnny dies when dally pulls the switch blade at the doctor and the shop owner. This makes the audience feel worried for the people around his safety. This aspect can be compared to when johnny killed bob at the fountain and he only done it because he was scared.
In The Outsiders by S.E Hinton Actions were used to show Darry did care about Ponyboy. We see this we Ponyboy and Johnny are in the burning church and after Ponyboy gets out darry slaps his back to put the fire out  and accidently knocks him out. This makes the audience feel scared for Ponyboy safety and how he will react to it. This aspect can be compared On The Sidewalk Bleeding when the drunk guy seen andy and thought he was drunk too because he couldn’t see the blood.

In The Outsiders By S.E Hinton emotions were used to show darry really did care about him. We see this when they are at the hospital just after the fire when Darry says “Why did you do that”and “The only reson I am so hard on you is becauce i dont want to lose you”. This shows us that the whole time darry did care about Ponyboy he just didn’t want him to get hurt or killed by anyone. This aspect can be compared to the night Ponyboy and Johnny sleeped at the park and when he got hom Darry Said “where have you been” and that was because he was worried about him.

2017 Year 10 2nd Film Assessment

In the film ‘The Power of One’ sound effects were a very important technique. The director John .G. Auildsen used this when borth through the stone at the chicken. This makes understand that botha wants to be as mean as possible to p.k. This was done to show that he did kill the chicken and he does not like the english. This reminds me of when pk pushes botha on to the flag and it stabs him in the butt lather in the scene.

 

Low angle shots are used effectively. For example the director used this when geel piet is in the prison and the guard makes him eat feces. This shows the guards have no respect to the prisoners. The director did this to show that the guards and prisoners do not get along. This combined with the sound effects made it seem very real. This reminds me of the scene geel piet gets beaten to death.

High angle shots were used well. We see this when the guard beats gee piet to death. This shows that the guards can get away with anything. This was done to show what it was like in those times and what people had to live with. This reminds me of the scene the guard makes geel piet eat feces.

Costume was a important technique. We see this when they are in the prison compared to what the people in the school. This shows that the blacks were not looked after and the whites got to have everything. This was done to show in the apartid time no one realy cared about the black they only cared about them selfs. This reminds me of when botha said that they are going to kill all english.
