Wind power - Hurumanu

Aim: To learn about the rate that different materials decompose. 

Hypothesis: I think that the bread will decompose first because it is the most easy-its to brake down.   

Materials:

1.   Schott Duran
2.   cardboard 
3.   strip of a plastic cup 
4.   3 coped bananas 
5.   test tube rack 
6.  Styrofoam  
7.   strip of bread 

Steps:

1. put the bread in the test tube   
2.  put the banana in the test tube 
3.  put the paper in its test tube 
4.   put all of four test tubes in the test tube rack
5.  put the Styrofoam in the test tube   
6.  pure a small amount in to the bread 
7.  and put somewhere where no one will touch it or brake it

Conclusion: 

Field, the Anemometer spun 80 spins per minute. It had a wind speed of 13-20 kph. This speed is 3 on the Beaufort Scale. (Leaves and small twigs in constant motion; wind extends light flag.)

The old J Block site, the Anemometer spun 60 spins per minute. It had a wind speed of 13-20 kph. This speed is 3 on the Beaufort Scale.

Grass Hill in the squad, the Anemometer spun 40 spins per minute. It had a wind speed of 2-5 kph. This speed is 1 on the Beaufort Scale. (Shown by direction of wind smoke drift, but not by wind vanes.)

Tennis Court gate, the Anemometer spun 12 spins per minute. It had a wind speed of 2-5 kph. This speed is 1 on the Beaufort Scale.

According to the data, the most spins on the Anemometer is on the field, with 80 spins per minute and it had a wind speed of 13-20 kph. The least spins on the Anemometer was by the Tennis Court gate, it spun only 12 spins per minute. It had a wind speed of 2-5 kph.

There thing i enjoyed 
1 seeing the animals 2 feeding the grafts 3 learning more facts about all the animal

Hi fellow readers this week on September the 25 Mt Ds and Al we left hornby high school in two buses when we got to orana park we talked about things we can do and not the we got given sticker with numbers on it and and the we split up into the groups with our numbers we went to see the lions and we learnt that the lions are Unlike other cats, lions are very social animals. They live in groups, called prides, of around 30 lions A pride consists of up to three males, a dozen related females, and their young. 

Then when we moved on from the lions we went to see the Gorillas it was so much fun seeing them play fight and eat hear are so facts we got told Gorillas have hands and feet like humans including opposable thumbs and big toes.Some gorillas in captivity have learned to use sign language to communicate with humans.Gorillas live in small groups called troops or bands. ...Gorillas live around 35 years. They sleep at night in nests.

My Investigation on climate change

ACIDIFICATION

DEFINITION:But overfishing and global warming threaten to leave oceans barren. The ocean is a continuous body of salt water that covers more than 70 percent of the Earth's surface.

What is happening to the oceans?

Carbon dioxide (CO2 ) is produced every day and absorbed by the oceans. As CO2 reacts with seawater, it lowers pH and reduces the concentration of carbonate ions. Motor vehicles and other transportation-related sources produce CO2.The ocean contains about 97% of all the water on Earth. The ocean plays a starring role in whatever happens with the environment. One big part of its role is to soak up energy (heat) and distribute it more evenly around the Earth.

What does this do to shellfish?

Higher temperatures and lower salinity will result in a habitat favored by microscopic bacteria in the oceans. More bacteria will impact marine species higher up the food chain. ... These can accumulate in shellfish such as mussels and oysters, putting the humans who eat them at risk.

Definition Ocean acidification refers to decreasing levels of pH in the ocean, which makes the sea more acidic. It is the long-term change in seawater chemistry due to the absorption of carbon dioxide from the atmosphere. Roughly 30 percent of human-made CO2 is absorbed by the oceans.

It is the long-term change in seawater chemistry due to the absorption of carbon dioxide from the atmosphere. Roughly 30 percent of human-made CO2 is absorbed by the oceans.

DEFORESTATION

DEFINITION:Trees and forests provide a habitat for many species of animals and plants. Tropical rainforests are among the most biodiverse habitats in the world. Trees provide shade and shelter, timber for construction, fuel for cooking and heating, and fruit for food as well as having many other uses.

What are trees used for? oxygen 

HOW DOES DEFORESTATION AFFECT THE CLIMATE?Trees provide them shelter from the weather and from enemies. Trees provide food in the form of fruits, nuts, leaves, bark, and roots. Even dead trees provide shelter and food for many insects.

ICE CAP MELT

DEFINITION:If all the ice melted what would happen?If all the ice covering Antarctica , Greenland, and in mountain glaciers around the world were to melt, sea level would rise about 70 meters (230 feet). The ocean would cover all the coastal cities. And land area would shrink significantly. ... That's because the ice doesn't just melt.

HOW DOES ICE CAP MELT AFFECT CLIMATE CHANGE?The primary cause of this phenomenon is ice-albedo feedback, whereby melting ice uncovers darker land or ocean beneath, which then absorbs more sunlight, causing more heating.

WATER VAPOUR

DEFINITION:Increased water vapor content in the atmosphere is referred to as a feedback process. Warmer air is able to hold more moisture. As the climate warms, air temperatures rise, more evaporation from water sources and land occurs, thus increasing the atmospheric moisture content.Apr 27, 2016

HOW DOES  WATER VAPOUR AND EVAPORATION CONTRIBUTE TO CLIMATE CHANGE? 

It is known that climate affects the ocean and the ocean affects the climate. Due to climate change, as the ocean gets warmer this too has an effect on the seafloor. Because of greenhouse gases such as carbon dioxide, this warming will have an effect on the bicarbonate buffer of the ocean.
