How fireworks are made

Fireworks, so colorful and bright they just light up the night sky, but have you ever wondered what they are made of?

Well i’ll tell you now. Fireworks are highly dangerous explosives that explode in the sky. They are long paper tubes filled with gunpowder/blackpowder which is highly flammable and can explode when put next to a heat source.  Sometimes they have projectiles that shoot  when the  gunpowder is ignited and the projectiles are filled with gunpowder and then the projectiles explode in separate areas. The fuse. The fuse is the thing that you light with fire, which then goes to the gunpowder to create the colorful explosion. The color of the fireworks comes from meal salts. When heated these salts create colors. Aluminium is used for white and silver fireworks. While all the other colors are made from different  elements like strontium carbonate maks cheerful red fireworks, calcium chloride makes great orange fireworks, sodium nitrate creates vibrant yellow fireworks, barium chloride makes bright green fireworks and  copper chloride makes deep blue fireworks. Some fireworks have separate projectiles shot at different times like long tube ones. The source of most fireworks is a small tube called an aerial shell that contains explosive chemicals. All the lights, colors, and sounds of a firework come from these chemicals. An aerial shell is made of gunpowder, which is a well-known explosive, and small globs of explosive materials called stars. Catherine wheels. The Catherine wheel or pinwheel is a type of firework consisting either of a powder-filled spiral tube, or an angled rocket mounted with a pin through its centre. A sparkler is a type of hand held firework that burns slowly and creates a colorful effect.  

So that concludes this text, have a great day!

My lock down reflection

My lockdown reflection 
In the lockdown  I learnt  that I can complete things in a time limit  such as these slides.
At first I thought I was going  to slag and not do things in time but then I learnt I was under estimating myself infact I was finishing in about an average of 2 hours including breaks.
What I learnt about my family was  that my dad could build bikes and he was great at making  things.
And I also learnt that my sister is afraid of dogs (she is 5).
 I learnt that there are a lot of  dogs mostly all you can hear is barking  when you walk past the houses on the street. Another thing that I have learnt is there is a lot more birds hanging around.
Another thing that I have noticed is a lot of emergency vehicles (police)  passing by about 2-3 a day

How Wolves changed the rivers

How Wolves changed the rivers

Tuesday 21st may 2019 

How do you think wolves transformed the rivers?

I’ll tell you now 

One of the most exciting scientific findings in the past half
century has been the discovery of widespread tropic
cascade a  tropic cascade is ecological
process starting from the top of the food chain
and tumbles down to the very bottom and a classic example
is what happened in Yellowstone national park in america
when wolves were reintroduced in 1995 we all know wolves
kill a veris species animals  but also give life to many others .

Before the wolves turned up they had been absent for

70 years wolves were reintroduced to Yellowstone national
park  in 1995. Since there were no predators to hunt the deer
there population grew larger and larger the deer simply they
grazed all the vegetation . as soon as the wolves arrived than
a remarkable thing happened ,yes they killed some of the 
deer then the deer started avoiding certain parts of the park
such as the canyons and gorges those areas regenerated the
height of trees quintupled in just 6 years. Bear valley sides
aspen,willow and cottonwood as soon as that happened, the
birds moved in the number of song birds migratory birds
started to increase greatly ,and the number of beavers started
to increase greatly because of the trees. Just like the
wolves beavers are ecosystem engineers and create leashes
for species and their dams make habitats for other  species
such as otters and muskrats ,ducks and fish.
the wolves killed the coyotes,as a result the number of rabbits
and mice increased.which meant more hawks more wesles
more foxes more badgers. Ravens, bald eagles
fed on the carien the wolves left bears fed on it to their
population started to rise to,partly also because there were
more bearys growing on the regenerating shrubs,and the
bears reinforced the impact of the wolves by
killing some of the calves of the deer. But here's where it gets
really interesting,the wolves changed the behavior of the
rivers they became meanderles there was less erosion the
chanels narrowed more pools formed more riffel
sections all of wich were good for wildlife habitats
but the rivers changed in response to the wolves. And the
reason was the regenerating forests stabilized the banks
so the rivers became more fixed in their corse . 
by driving the deer out of some places and the
vegetation recovering on the valley side there was les soil
erosion . wolves small in number changed
yellowstone national park .

fishing for the future

Fishing for the future

Fishing for the future is important because

There will be no more fish, first I’ll tell you about boat safety.

Water safety is important because 291 people

have died in 2017 because of not wearing a life jacket ,
life jackets help you keep a float when the boat crashes

Now i’ll talk about the fish

When you catch a fish  make sure

when you pick up the fish you use a  wet towel so the fish
doesn't lose its protective coating the protective

coating acts like sunscreen
 otherwise the fish will burn and die, if you don’t have
a wet towel make sure that your fingers are wet

Another thing about the fishing is that

you use salt water ice. You need salt water
ice because it helps keep it fresh, normal ice on the
other hand makes the fish go of

Also when you catch a fish you have to measure
the fish From the tip of the nose to the middle of the tail

with a Fish ruler eg snapper has to be 30cm if it

is to small let it go, if it  is to big let it go.

Next up seabirds

Did you know More than 10,000
seabirds caught by commercial fishermen
since 2013 the most common seabirds to be caught
ver petrels albatrosses.  Out of 9,000 bird species
worldwide, only 360 are seabirds. Of these, 86 breed in
New Zealand and nine breed in other places but
visit New Zealand each year. A number of other species
visit from time to time. New Zealand's
seabirds include
penguins, albatrosses,
petrels, shags, prions, gannets and skuas.
