Wind speed - Making an anemometer.

MATERIALS: 

1. Pins 
2. Cups  (x4)
3. Pencils  
4. Straws (x4) 
5. Tape  

STEPS

1.   Put 2 holes in each cup 
2.   Put your straws in a cross 
3.  Tape the cross of straws together (go around with tape 3 times) 
4.    Then pin them done in the pencil with a rubber in it 
5. Then put the cups and straws together  

 Once you have made an anemometer we are going to record the wind speed.

Group size: 5

You will need:

Anemometer (above) 

Roles:

• Timekeeper
• Counter
• Recorder
• Anemometer Manager
• Wind generator

1. Mount the anemometer in a place that has full access to the wind from all directions.
2. When the timekeeper says "Go", the counter in each group will count how many times the marked cup passes them in one minute and write it down.
3. If possible, repeat the above step four (4) times and record the average number of spins on the chart.

Hurumanu- Recycling

Aim: To learn practical ways of recycling so that we can make our world a better place.

 

The Zero Waste Climate Solution movie

 

How can we prevent climate change by recycling these products?

 

Plastics:

Cycling or walking: 

Paper:

Steel: 

 

 

 

AT WHAT RATES DO DIFFERENT ITEMS DECOMPOSE?

MY INVESTIGATION.

 

 

 

Choose 5 items from the list and investigate them. 

 

You need to answer three questions.

 

Name: Nappy 

 

1. How long do they take to decompose?  200 - 500 years 

2. What resource/fossil fuel are they made from? The components to making a disposable nappy are waterproof, wood pulp and synthetic polyacrylate (cloth Diapering) Disposable diaper, polyethylene plastic are used and the raw material for this is the oil: it takes 1 cup of crude oil to make the plastic for one disposable diaper.

3. How is this resource recycled?

4. How does this object contribute to climate change?

 

Fossil Fuels

 

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

Definition of Fossil Fuels:
A natural fuel such as coal or gas, formed in the geological past from the remains of living organisms

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.   Wood
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

What Fossil Fuels are mined?
Coal is extracted from the surface of the earth or from deep within the earth (Called underground mining)

Where are they Mined?
1. Coal is mined in South Africa, America, USA, England.

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.   Plate
3.   Toothpick

Steps:

1.   Get your materials
2.   Get your cookie and put it on your plate
3.   Grab your toothpick and start mining 
4.   See if you can get all the chocolate chips out of your cook from the outside
5.   And then enjoy the rest of the cookie.

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

Findings: What did you find out as a result of your mining?

That it was a little hard but easy at the same time because we had to mined it without the cookie breaking.

Conclusion: 

It was really enjoyable and easy.

Investigation

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

Write a definition, upload an image and list where these fossil fuels are mined.

1. Coal  -West Coast NZ
2. Oil  USA, Saudi Arabia
3. Natural Gas - North Island NZ

Write a paragraph of 5 sentence,upload an image and name 2 countries that use this type of renewable energy.

1. Solar - Solar energy comes from the sun. Solar panels can be erected on buildings to draw energy from the sun. This energy is used to heat houses and provide hot water for washing and cleaning.
2. Wind - Wind spins turbines that generate power. The stronger the wind, the more energy is produced. These don't work where there is no wind, but are great in areas where there are strong winds e.g. Scotland.
3. Waves - 
4. Hydro - Hydro dams are built to create a back up of water that can be released to drive turbines which create electricity> The electricity is wired all around the country through pylons.

Write a 5 sentence reflection about what you have learnt about Climate Change and how it is going to affect us in the future.

Investigation.

Research the following Biomass fuels. You will need to:

Write a definition of fuel.

Write 8 sentences about fuel. 

• How is it made? 
• Where is it made? 
• What is it made with? 
• What countries use it? 
• What uses will it have in the future?  

Place 1 image of the fuel.

Biomass Fuel types.

Name Agricultural crops and wood fuels.

Definition: Agricultural crops such as miscanthus and straw from cereal crops can be used as a fuel for production of heat. Herbaceous materials have a different composition from wood and its combustion must be handled differently from the wood.

Research:

• How is it made?  Wood energy is the use of wood fuel to produce heat or electricity. It comes in several numbers of forms, including firewood, shavings, sawdust, wood chips, agricultural crops, and bark.
• Where is it made? Wood biomass is the main source of wood energy in New Zealand and it comes in a number of forms.

Name Animal waste.

Methane Gas

Definition:

methane. A colorless, odorless, flammable gas that is the simplest hydrocarbon. It is the major constituent of natural gas and is released during the decomposition of plant or other organic compounds, as in marshes and coal mines. Methane is the first member of the alkane series.

Research:

How is Methane Made? 

Methane is produced at shallow levels (low pressure) by anaerobic decay of organic matter and reworked methane from deep under the Earth's surface. ... Methane is generally transported in bulk by pipeline in its natural gas form, or LNG carriers in its liquefied form; few countries transport it by truck.

Where is Methane Gas made?

Methane that is produced and released into the atmosphere is taken up by methane sinks, which include soil and the process of methane oxidation in the troposphere (the lowest atmospheric region). Most methane produced naturally is offset by its uptake into natural sinks.

Image:

Name: Biogas

Definition: Biogas is the mixture of gases produced by the breakdown of organic matter in the absence of oxygen. Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste. Biogas is a renewable energy source

Research:

How is it made? Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste. ...

Where is biogas made?

It occurs naturally in compost heaps, as swamp gas, and as a result of enteric fermentation in cattle and other ruminants

Name: Biofuels

Definition: A fuel derived immediately from living matter.

Research:

How is Biofuels made?

Biofuels are designed to replace gasoline, diesel fuel and coal, which are called “fossil fuels” because they are made from animals and plants that died millions of years ago. Biofuels are made mostly from plants that have just been harvested. There are three main types of biofuel. Ethanol, biodiesel, and biojet fuel.

Where is Biofuels made?

Ethanol fuel is the most common biofuel worldwide, particularly in Brazil. Alcohol fuels are produced by fermentation of sugars derived from wheat, corn, sugar beets, sugar cane, molasses and any sugar or starch from which alcoholic beverages such as whiskey, can be made (such as potato and fruit waste, etc.).
