Hurumanu: The Water Cycle

AIM: TO LOOK AT THE WATER CYCLE AND HOW CLIMATE CHANGE IS AFFECTING IT.

Definition:

Water circulates between our earth's oceans, atmosphere and land. Involving precipitation such as rain and snow, drainage in streams and rivers return to the atmosphere by evaporation and transpiration.

Scientific words:

• Evaporation. When water is heated by radiant energy it turns into water vapor.
• Transpiration. Evaporation from plants.
• Condensation. When water vapor cools, molecules join together and form clouds.
• Precipitation. When clouds get heavy the waters falls as rain, sleet, hail, or snow.
• Acidification: the action or process of making or becoming acidic.

We will be conducting an experiment that looks at the different ways that climate change is affecting the water cycle.

THE WATER CYCLE EXPERIMENT

Bag 1: Normal Water cycle

Bag 2: Water cycle with CO2 added: like Oceans in climate change

Bag 3: Water cycle with ice added: like Antarctica in climate change

Material:

1.  Plastic bag
2.  Vivid maker 
3.  One cup water
4.  Two drop of food colouring
5. litmus paper 
6. soda 

Steps:

1. Get into a group
2. Get the material 
3. draw the water cycle on a zip lock bag 
4.  put a cup of water in the zip lock bag
5. put two drops of blue food colouring 

Two Images:

Findings:

Conclusion: I well have more of a conclusion next week. What I know about the water cycle is that the water  from the sea evaporates because of the sun and goes to the clouds then goes back in the sea by the rain

For the second bag we used soda water to show what is happening to our ocean because of climate change. We used soda water because the gas in soda water is carbon dioxide.     

Charlesworth reserve

This week for CIP some of the year 7 & 8 are planning to go on a trip to Charlesworth reserve. Charlesworth reserve is parks and Gardens in Christchurch and it is only 24 minutes away from our school. The government in New Zealand has asked and other helper to plant 1 billion trees in Charlesworth Reserve by 2028. If we don't have enough trees we need in the word the carbon dioxide will invade our earth. The earth will then be hotter and soon many species animals and human will be extinct. Charlesworth reserve is a park located in bromley, in the middle of ferrymead. Charlesworth Reserve is a wetland edge walk featuring restoration planting, wetland birds and tidal pools. 

The reserve covers half the land that was drained in the 20s and it was used as pasture. 

Charles Worth reserve Is a 20-ha restored remnant salt marsh on the western edge of the Avonhealthcote Estuary in Christchurch. 

The area was drained and refilled in the 1920’s for grazing. 

In the early 1990’s the Christchurch City Council started restoring the area by creating tidal pools and planting plants. 

Charlesworth reserve was named after Captain William Charlesworth because he was the first one to step a foot on that land that land there for he owned it.

He was born in 1814 and he passed away in 1875.

 In August 2017 over 100,000 plants were planted in the Reserve by volunteers and the Christchurch City Council and Park Rangers since restoration began.

 Between November 2015 and December 2017 tracking tunnels were used to monitor small animals to give a coarse index of relative abundance. 

The presence of lizards can also be obtained by this method. 

At the same time terrestrial arthropods were monitored by using artificial habitats. 

The Tracking tunnels were baited these are the dates that they were tracked on. 

30 Nov 2015, 2 Feb 2016, 12 April 2016, 6 June 2016, 8 Aug 2016, 9 Oct 2016, 4 Dec 2016, 6 Feb 2017, 9 April 2017 and 7 Aug 2017. The tracking cards were collected the next day. Tunnels were not baited in June 2017 because of weather conditions. 

We are going up to charlesworth reserve to plant native trees so that some of our native birds come back.

THE BIG PICTURE

What animals keep our jackets warm?

there are a lot of animals the keep our jackets warm red foxes, coyotes, mink, fishers, river otters, marten and weasels. 

What animal makes our boots waterproof?
the animals that keep are boot dry is duck

Where does the water in our rivers come from?

the water from the river comes from the melting snow and rain 

Why do we need healthy rivers?
our rivers provided us with clan water to fertilise plants for food water to drink and water to stay clean  

What are some of the good things about mosquitoes?

If mosquitoes went extinct the animals the feed off of there larvae would suffer. 

they also clean the water

Why are bees dying?

bees are dying because of Colony collapse disorder

What do bugs do to our leaves

Reuse

Recycle 

Reduce

How much dung would we be in if there were no dung decomposes?
there would be not much dung because we need it to putt in our jackets

Who runs this planet?

mother nature 

Fossil fuels

Hurumanu - Fossil Fuels.

 

Aim: To look at how fossil fuels are contributing to climate change and how we can prevent this.

Definition of Fossil Fuels:

solid material naturally from caves minded to make fuel 

gases from the earth surface

Scientific Terms for Students

• coal: a dark-brown to black solid substance formed naturally from the compaction and hardening of fossilized plants and used as a fuel primarily for electricity generation
• natural gas: a mixture of hydrocarbon gases that occurs naturally beneath the earth’s surface and is used as a fuel primarily for cooking and heating homes
• renewable resource: a resource that is never used up (e.g., solar energy)
• non-renewable resource: a resource that is not replaceable after its use (e.g., coal, gas)

Examples of Fossil Fuels:

1. coal  
2.  gas 
3. oil

Activity: 

In groups of 3 you will learn about different fossil fuels and the way they are mined?
Each group will be given a fossil fuel. The recorder will read it to the group. The recorder will write down some of the important points.
Person 1: Recorder: to write down 5 points of interest from the text. 

1. 5 Points:
2. Positives and negatives of your type of mining.

Person 2: Reporter: to read back to the class their 5 points of interest.
Person 3: Collector: Gathers the required stationary from the teacher.

Mining Fossil Fuels

How are they mined?

1. scraping 

2. digging

3. Drilling

4. exposing 

Where are they mined?

1. Deep within the earth through under ground mining

2. You can find fossil fuels around the surface of the earths crust

Activity;

On the sheet provided you need to make two drawings of your cookie. 
1. looking down at it. 
2. side on -  of the imaginary habitat that will live on the top of the cookie. ( trees, buses, flax, sea, etc)

Material:

1.  cookie
2.  sheet of paper
3.   pencil
4.  plate
5. tooth pick

Steps:

1. get the materials  
2.  draw what the cookie looks like 
3.   draw the cookies habitat 
4.   answer the question
5.   mine the cookie
6. draw what it looks like after
7. draw what the habitat looks like after
8. eat the cookie

Once you have drawn your cookies you must take 2 pictures and upload them to your blog.

after

Findings: What did you find out as a result of your mining?
That the cookie was normal then turned different after picking out the chocolate chips. The cookie changed in taste as well once picking out the chocolate chips. The habitat was a beautiful place the go to until one day mining happened there are the habitat complete changed.

Conclusion: Today I learnt that more about the three departments of fossil fuels which are coal, oil and natural gases. I would like to learning more about the three departments mapping around the world. I liked today's lesson but especially liked mining a cookie and a habitat

Hurumanu - Climate Change

Aim: To look at the causes of climate change and how to prevent it.

Climate Change video; The Facts video

As you watch the video answer these questions:

What is our greatest threat in thousands of years?

too much pollution and the water level will rise. So climate change

How do we see climate change affecting the globe?  

1. I see climate change affecting the globe with the temperature witch melts the ice causing human extinction 
2. Cars affect our earth by letting out carbon monoxide
3. With climate change I believe the there will be a lot of pollution in our world  
4. Also with the temperature getting warmer our world might dry up and we could die    

What is needed to change history?

There is no way to change the past bet there is always a chance to change the present 

Is climate change a man made disaster?

 climate change is man made disaster cause of all the gas and fossil fuels has been caused by man kind an.

Dramatic action must be made in the next - years to change it?

actions must be mad in about 10 year and maybe then our planet and us might have a chance

Why is our climate changing?

 people are not looking after the environment which makes a lot of pollution 

What is causing the warming trend of the climate?

the carbon dioxide is trapping the heat from the sun like a blanket.

When the sun comes done it would bounce up but cause of the carbon dioxide it can't.

What is the main problem?

the main problem is the climate change cause the is causing the temperature heating up and the sea levels rising so if you think about it every thing links up to climate change 

What are examples of these?

it is to hot for some animals to survive 

Burning fossil fuels releases what gas?

 when fossil fuels are Burning it releases nitrogen and carbon.

How much hotter now is our world?

0.77C warmer than the 1951-80 average

What do we call this global warming?

we call it climate change

How is this affecting creatures / animals like bats?

this temperature is killing the animals like bats they just can't take it

What percentage of species are near extinction?

99.9%

How could this effect the world ecosystems?

Each organism has its own part and reason. when we introduce factors such as too much carbon dioxide or methane. It destroys the balance of the ecosystem which in turn affects those who live in it. The results is global warming

What global change was seen and recording breaking last year?

2018 was the 4th hottest year on record. it was  1.5 Fahrenheit more on average set between 1951 and 1980.

How is climate change affecting our weather systems?

1.wind 

2. waves

3. hydro

What is another effect of climate change?

extinction

What will happen if the ice melts in Antarctica and the Arctic?

There will be no more land

How does this affect people?

They get hot and grumpy and soon the might be dead

What other things affect oceans change?

pollution

What does too much heat do to the coral?

kills it

Why did some industries not want to stop burning fossil fuels?
maybe they didn't want to stop because they were greedy and they knew it was a way to get money.

sea levels rises by 20 cm

Investigation

You can decide on how you would like to do this investigation. Your presentation could be on the blog, slides, or power point.

Investigate the different Fossil Fuels listed?

1. Coal
2. Oil

Write a paragraph and upload an image about each of these renewable energies.

Solar


Solar is our sun that produces energy for us and gives us sunlight that goes into electricity. concentrated solar power systems use lenses and or mirrors and tracking systems to focus a large area of sunlight into a small beam.

Wind

Wind energy is a type of form of solar energy. Wind energy describes the process by which is used to generate electricity. Wind turbines convert the kinetic energy in the wind into mechanical power, and a generator can convert mechanical into electricity.

Waves

Wave power is the capture of energy of wind waves to do useful work. for example:

electricity generation, water desalination, or pumping water. A machine that exploits wave power is a wave energy converter.

Hydro
