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.

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.).

  5.  1 Sheet Of Black Paper 
  6. Thermometer
  7. 1 Large Cup 
  8. 1 Heat Lamp 

Steps

  1.   Get all your materials 
  2.  Filled all 4 cups quarter the way fill
  3.  then get your one sheet of tin foil 2 sheets of white paper and your other sheet of black paper
  4.  put one cup on each of those sheets 
  5. Check the temperature of them all before you turn on your heat lamp 
  6.   Turn on your lamp or leave them sitting in the sun
  7. Check it every 15 minutes 3 times for an hour.


Which surface conducts/attracts the most heat?

Water Cycle

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

Definition:


Image result for water cycle

A green box with icons and white text. Text reads: Where is Earth's Water? 96.5 percent is in the oceans; 1.7 percent is in lakes, rivers, streams, and soil; 1.7 percent is in polar ice caps, glaciers, and permanent snow; 0.001 percent is in water vapor in Earth's atmosphere

Scientific words:


  • Evaporation. When water is heated by radiant energy it turns into water vapour.
  • Transpiration. Evaporation from plants.
  • Condensation. When water vapour 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.An illustration of the water cycle showing how water travels from rivers and streams to clouds to snow and back again

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 Marker.
  3.  1 cup of water.
  4.  2 Drops of food colouring.

Steps:

  1.  Get a plastic bag.
  2.  Get a vivid
  3.  Draw the water cycle on the plastic bag.

Other comments:

1. Water cycle 1 had no acidity
2. Water cycle bag 1-2-3 both have small amount of drips in them
3. Water cycle bag 1,3 have no acidity in them
4. Water cycle bag 1-2-3 all cycle 


Conclusion:

It was fun and I learned heaps

Charles worth Reserve

Charles worth Reserve

That to expect:

Charles worth Reserve’s habitat is a restoration of tidal wetland and surrounding coastal shrub land and forest. This is an important habitat for native wetland birds and will become increasingly important as a habitat for bush birds, lizards and native insects as the vegetation matures. 

Regular working bees:


Join Christchurch City Council and Avon Heath cote Estuary Itaipu Trust
(external link)
 every Sunday afternoon to help maintain Charles worth Reserve. Tasks depend on the season and weather but generally involve planting, pruning, watering and invasive weed removal. 


Community:

Join in the fun at Charles worth Reserve's annual planting day!
This year's annual event was held on 19 May and attended by 95 people. Trees for Canterbury
(external link)
 kindly donated 1600 seedlings which were all planted in an amazing effort. 

Want to help out at Charles worth? Head to a regular working bee or be the first to find out about upcoming events and register your interest.
What to bring:
  • Appropriate clothing for any weather: sunhat, warm jacket and raincoat
  • Sturdy footwear or gumboots
  • Personal work gloves
    • Tools, sunscreen and gloves are supplied.

Oil Polution

Oil is polluting our water from ship spillages and waste oil through sewage pipes 
Oil spills make up about 12% of the oil that enters the ocean. The rest come from shipping travel drains and dumping. An oil spill from a tanker is a severe problem because there is such a huge quantity of oil being spilt into one place. Oil spills cause a very localised problem but can be
strophic to local marine wildlife such as fish birds and sea otters. 
Oil cannot dissolve in water and forms a thick sludge in the water. This suffocates fish, gets caught in the feathers of marine birds stopping them from flying.
