Nitrogen cycle

Everything in this whole world is made out of atoms and molecules. Atoms and molecules are so small that you cannot see them. Another oxygen, represented by the letter O. When 1 nitrogen atom combines with 2 oxygen atoms they form a molecule called NO2. The name of NO2 is actually called nitrogen dioxide. Nitrogen dioxide combines with other toxic gases, the brown haze is called smog. 


Airborne Nitrogen

Nitrogen is one of the 90 elements, or pure substances that exists on the planet Earth. About 78% of our air sis made out of N2. Nitrogen's other name is called inert gas. Nitrogen atoms don't react with other atoms. Here's a fact, light bulbs actually contain nitrogen (N2).


Nitrogen Compounded 

Because that nitrogen atoms don't really bond with other atoms, not many nitrogen exist naturally on Earth. Protein molecules in animals and plants contain nitrogen. Protein is part of all our cells and bones even more. A small amount of compounds called nitrous oxide gas (N2O) exists naturally in our atmosphere. A compound called sodium nitrate (NaNO3) or Chile saltpeter, is found underground in South America, liquid nitrogen is so cold if you put a berry in liquid nitrogen it will freeze. 


The Nitrogen cycle

Every living thing is also part of the nitrogen cycle. Here is the cycle of nitrogen. Nitrogen travels from the air to soil  to plants and to animals, and back to the soil and air.

How fireworks are made?

 How fireworks are made?


Wow! Look at the wonderful fireworks in the bright moon light. Do you ever wonder how fireworks are actually made?


Well fireworks are really dangerous if you get hit and they also explode in the sky. Fireworks are made like this, first they use really long paper tubes filled with gunpowder. That’s why fireworks are dangerous because of the gunpowder inside. When you light a firework with a hot material it just shoots out. Aluminum makes the white and silver colors. There are also metal salts inside fireworks like strontium carbonate that makes red fireworks, calcium chloride makes orange fireworks, sodium nitrate gives the fireworks a bright yellow color, barium chloride is used for bright green fireworks and copper chloride is used to make deep blue fireworks. So then when you heat up fireworks it makes a loud crackle and explodes in the sky. So that’s how fireworks are made.

How do jellyfish sting?

Why do jellyfish sting?


Jellyfish use their venom as a defence  mechanism to protect itself and to kill prey. Their venom is made of toxins that attack the heart, nervous system and the skin cells making its prey paralysed or shocked. The jellyfish has 15 tentacles and each tentacle has about 5,000 string cells, which are triggered by by the presence of the chemical on the outer layers of its prey. The cells in the strings are called cnidocytes and the venom is actually called nematocysts. The venom paralyses 

Why do skunks smell?

Why do skunks smell.


Skunks smell because they have 2 glands. First the skunk produces the spray in the glands on the tail. It is actually a type of unpleasant odor that they use to defend themselves from their own predators. The name of the odor is called N-butyl mercaptan that they make from their tails. The smell is actually made of a sulphur mixture. The smell also contains chemicals like thiols which actually has a bad smell. So that's the way the skunk builds its smell to defend themselves.

T4W4 writing

 I am so exited I'm not going to camp. Why because I throw up on food almost every time. I like to learn and study at school so I can be smart. We also get time to do our schoolwork all day. I also always get to read fun books. I also get some time to do some biology and chemistry. I love to learn about bugs and spiders and we can make insect enclosures in the containers I brought.

Around the world we have an ecological cascade meaning that if there were no whales there would not be that much fish in the ocean. So that means that whales are actually apex predators. We find out that whales eat fish , krill and shrimp but that is not what they only do in the ecosystem, and we start to kill whales because of what we do but that does not mean we should kill all of them if we kill all of them and the fish and krill will decline their populations. They can help the ocean as well.



The whales first go down under the dark waters to feed on fish and krill that they can catch then after that go up to the photic zone where there is enough sunlight where there is enough light for photosynthesis to happen. When they are upto the photic zone they come out to release something called fecal plumes which are rich in iron and nitrogen, those nutrients are really scarce in the waters, then those fecal plumes fertilize the plant planktons, the place where plant planktons are only where plants can survive: the photic zone. They also kick up plankton up into the photic zone so that it gives out more time for the plankton to reproduce before it sinks down to the bottom called the abyss. Plant plankton don't only feed the animals of the sea but they also absorb carbon dioxide from the atmosphere. Then eventually it sinks to the ocean floor, it takes the carbon out of the circulation, down to a place where it remains for years. 



So that’s why we should not kill all the whales because if we kill all the whales in the ocean there will not there will not be enough plant plankton in the ocean to help the fish so we should keep whales all all alive. The more whales there are, the more fish and krill there will be to sustain the whole ocean. So don’t kill all the whales in the ocean, killing whales ruins the whole ecosystem. Don’t ever kill a whale!

W1T4

 At the end of the driveway, the world skims past.

At the end of the world, the world is skimming away.

Kids slide through on the pathways and rubbish bins.

Kids wander away, all around the pathway.

In summer blaze and autumn falls

Kids walk home in their school uniforms.

Inside their jumpers, their hands warm 

Inside their jumpers, the kids feel warmth everywhere they go

The boy plays around  with his friends: Not yet seeing not yet  knowing

That what's gone is a new beginning, that what begins is already growing slower and slower  

Adults with their jogging legs

Swish by in trains to adult workplaces

 The haka is used when you want to play sports or it was a language week they will do the haka. The first person to create the haka of New Zealand was Te Rauparaha who escaped from a tribe called the Natagi  Maniapotta when he made a mistake they chased him out of their own tribe so them he decided to hide in a vegetable field and hid himself from that tribe. They used it to show how strong they were when they wanted to face another team in a sports tournament or not.

Crocodile Picasso art

This is the Picasso art I made. Picasso used different types of colours and chopped everything everywhere all around the image. So I think this is a inspiring art.

Polynesian Panthers

 The Dawn Raids come in the dawn to catch people who did not have the licences to come into New Zealand. Then they come in and smash the doors open when they were still sleeping to check if the come in legally. Then they will ask for their passports or their CV and they were arresting heaps of the Pacific if they came here illegally.  When the Polynesian Panthers saw that they started to repay to teach them a lesson to stop what they were doing.
