Hello my name is Andrik Tan from class 5-777


here are five facts about Antarctica ecosystem:


1. The first confirmed sighting of the continent was in 1820

2. Explorers first reached the south pole in 1911.

3. Because Antarctica lies in the southern hemisphere,seasons there are the opposite of seasons in the north-summer runs from october to february and winter cover the remainder of the year.

4. Antarctica is the coldest continent temperatures in the winter can drop below-73C (-100F).

5. The name Antarctica comes from a Greek word meaning opposite to the north.

Hello, my name is Annira Benitez. I am working on the Antarctica ecosystem with my partners Nana Kamissoko and Jaquelyn Alvarez. Here you will find all kinds of information on Antarctica! Enjoy :)


Hello, my name is Annira Benitez and today I will tell 5 INTERESTING facts about this ecosystem


Annira's 5 Facts on Antarctica:


1.) The first confirmed sighting of the continent was in 1820

2.) Because Antarctica lies in the southern hemisphere, seasons there are the opposite of seasons in the north — summer runs from October to February and winter covers the remainder of the year.

3.) Antarctica is the driest continent; it is almost entirely desert. Very little snow or rain falls on the continent, but because it is so cold, the small amount of precipitation that does fall does not melt

4.) Antarctica is the coldest continent; temperatures in the winter can drop below –73°C (-100°F)

5.) Explorers first reached the South Pole in 1911


There you go! I hope this helped you one way or another!

Hello, my name is Annira Benitez and today I will tell you how Antarctica is in danger with 2 main problems.


Antarctica is in great DANGER!!!:


Scientists have proven that Antarctica's ice caps are SHRINKING because they have melted!!

Antarctica global warming has become a burning issue of the present time. Global warming in Antarctica will pose a serious threat to the rise in water level. Hence, Antarctica global warming has become a great concern for the scientists and researchers. As most of this continent is covered by ice, the impact of global warming is more acutely felt here. With the increase in the number of automobiles, air pollution has been on the increase in the last 20 years. This is one of the major causes of global warming. Moreover, the chimneys of the factories all over the world emit various types of gases, which pollute the air to a great extent. If the air continues to get polluted at such a fast rate, it will definitely cause a rise in the general temperature throughout the world.
And the MAIN reasons for this to happen is for 2 reasons and 2 things ONLY: Us (as in people in general) and Global Warming.....
Because if you really want to be accurate, we are actually the one and only reasons because WE are the ones who cause global warming, global warming doesn't happen on its own.
So lets put it this way, And the MAIN reasons for this to happen is for 2 1 reasons and 2 1 things ONLY: Us (as in people in general) and Global Warming......
Don't you know that we are the one of the reasons of why soon the Arctic will be nonexistent?
We have driven some Antarctic species to the verge of extinction for economic benefit, killed and disturbed other species, contaminated the soils, discharged sewage to the sea and left rubbish, cairns and tracks in even the most remote parts.
For all of our foolish mistakes, we are costing many of those arctic animals' homes.
The evidence that humans are causing global warming is strong, but the question of what to do about it remains controversial. Economics, sociology, and politics are all important factors in planning for the future.
Even if we stopped emitting greenhouse gasses today, the Earth would still warm by another degree Fahrenheit or so. But what we do from today forward makes a big difference. Depending on our choices, scientists predict that the Earth could eventually warm by as little as 2.5 degrees or as much as 10 degrees Fahrenheit.
A commonly cited goal is to stabilize GHG concentrations at 450-550 parts per million (ppm), or about twice pre-industrial levels. This is the point at which many believe the most damaging impacts of climate change can be avoided. Current concentrations are about 380 ppm, which means there isn't much time to lose. According to the IPCC, we'd have to reduce GHG emissions by 50% to 80% of what they're on track to be in the next century to reach this level.
Burning fossil fuels increases the level of carbon dioxide in the atmosphere, and carbon dioxide is a major contributor to the greenhouse effect and global warming. You can help to reduce the demand for fossil fuels, which in turn reduces global warming by using energy more wisely.
The Antarctic Peninsula has a temperature that has risen over 2.5 degrees over the last 50 years. This is two or three times faster than the rest of the world. The other region of Antarctica that is not the Antarctic Peninsula – 96% shows no sign of rising of water or loss of ice. But if the temperature keeps rising this will change. If this keeps happening, then the whole world might flood. In West Antarctica, there is a massive ice shelf that would take 100,000 years to melt, (raise sea levels by 16 feet) but if we don’t do something about global warming, then some dramatic things may start to happen.
The state of the global climate is shifting drastically out of proportion with the natural balance of the earth.
The Antarctic ice cap is melting and losing mass at a drastic rate.
This increase in greenhouse gases has caused a hole in the ozone layer which has increased climate at the north pole. An increase in the climate there has caused a climate change in Antarctica including an increase in ice levels around certain regions . This is because the winds produced by this climate change have caused a warming change to the western coast of Antarctica while increasing cooling trends elsewhere.
This means that we will see more drastic weather changes and more species of living organisms going extinct. The primary cause for this shift in global climate is the increase in greenhouse gases.
Well, instead of people just reacting to all of this happening, how about we finally DO something about it?
So for all us to get an idea of how we can ACTUALLY HELP is the following information below. I will state the problems in Antarctica due to us/ global warming and how we can prevent more damage:


Problems in Antarctica:

What effects Global Warming does to Antarctica:

~Climate change (in other words global warming) make glaciers and ice shelves melt


What effects we do to Antarctica:

~People transporting invasive species in like rats or deer on ships

And here comes the big one:

~Environmental damage caused by scientists and tourists visiting the continent

As my points cleared the most damage was caused by what people have done.

The solution people have thought of is that terms of reducing the number of invasive pests, rat and reindeer are already being removed in South Georgia. Ships must be as rat-free as possible, and containers showing signs of rat damage are not loaded onto the shore. Dogs and other non-native animals are no longer allowed in Antarctica.
There are many solutions to Antarctica melting but the hard part is letting people know how bad this situation is. People need to know that if we don’t do something, then terrible things will start to happen. Here are some solutions. • Alcohol – run cars • Solar Powered cars • Solar & Nuclear energy • Raising the price on products that lets out lots of Co2 so people will be reluctant to buy them.
Whereas, we must remember: Reducing the effects of climate change means reducing our CO2 emissions. This means everyone making the effort to turn off lights, recycle, walk to work, take public transport, and so on.


Global Warming does not only happen in Antarctica, so that's why we must TRY to eventually abolish it or at least take damage off it!!!

Well, hopefully in the future everyone will know how bad this actually is. With some thought out decisions and everyone pitching in, we might have lowered these temperatures down a bit. But if we don’t actually start to do anything, the whole world may flood! Temperatures rising can be a big thing to the way our world works. Some species of fish may die out and affect the food chain. If we don’t do something, everything will change.
If you would like to know where to get more information you can check: https://www3.epa.gov/climatechange/basics/
I hope my reasoning inspired you to take place and help to decrease CO2 emissions!

Antarctica

Antarctic Project By : Nana Kamissoko, Jaquelyn Alvarez, and Annira Benitez

Hello, my name is Nana Kamissoko I am working on the Antarctic ecosystem with my partner Jaquelyn these are the five facts I have researched on Antarctic ecosystem.


1.)The Antarctic region is found in the northernmost part of earth

2.)The name antarctic comes from a Greek word meaning near the bear

3.)Over the recent years, the Antarctic region has shrunk due to global warming

4.)The coldest recorded temperature in the antarctic is around -68 degrees c (-90 degrees f)

5.)The Antarctic region is home to the north pole


Hello my name is Nana Kamissoko here are the definitions of words I researched.

What is an ecosystem?

An ecosystem includes all the organisms in an area and environment in which they live.

What is a population ?

All the organisms of one kind in an ecosystem are called a population.

What is a community ?

Populations living and interacting with each other form a community .

What is a niche ?

A niche is when an organism has a specific role in an ecosystem.

What is a biome?

The term biome means the main groups of plants and animals


Hello, my name is Nana Kamissoko me and my partners Annira Benitez and Jaquelyn Alvarez are working on Antarctica here are my pictures on there food chain energy pyramid and food chain .

Hello, my name is Nana Kamissoko and I am here to show you a very important issue that is happening in Antarctica. Here is my explanation on it; enjoy!


Let's STOP Global warming in Antarctica:

Do you wanna stop this crisis with Antarctica this is all you have to do: READ THIS AND STOP THIS NOW !!!!!!

As you know us humans breathe out CO2 making global warming affects rise so we can not stop that but we can RECYCLE ! Which, we all take for granted but CAN save Antarctica the next time you think to leave the lights on when no ones around think about those Arctic animals aka polar bears in need please do it for them.

ANTARCTICA IS BEING HARMED Antarctic environments are being harmed in the following ways.....


* Climate Change resulting melting glaciers and ice shelves .(The Climate Change is due to the major problem GLOBAL WARMING.


*People transporting invasive species in like rat or deer on ships.

* Environmental damage caused by scientist and tourist visiting the continent.

Reducing the effects of climate change means reducing our co2 emissions.



These are just some of the interesting facts on this website I totally recommend you checking it out

Thank you for reading my points on how we can save this ecosystem I hope you learn from this. I rest my case.


Hello my name is Jaquelyn Alvarez and me and my partners Nana Kamissoko and Annira Benitez are here to give you more 5 facts on Antarctic

Jaquelyn's 5 Facts:

1.)The name ''Antarctica'' comes from a Greek word meaning 'opposite to the north'

2.)Antarctica is bigger than Europe and almost double the size of Australia

3.)The coldest record temperature on Earth occurred in 1983 at Vostok station, Antartica measuring a rather chilly-89.2°C (-128.6°f)

4.)Antarctica is the coldest, windiest, highest and driest continent on the planet

5.)Antarctica's ice is so heavy that it deforms the south pole, in fact, its weight makes the Earth look slightly pear shaped.

What is an ecosystem?

An ecosystem is a complex set of relationships among living resources,habitats,and residents of an area.

What is a population?

A population is a group of living organisms of the same species has the same creatures living in the same habitat.


what is a community?

A place that supports the people who live there

What is a Niche?
An organism's 'niche' is its place in the system: where it is found, what it eats, what eats it, how and where it gets food, etc.

















Hello!!!!.My name is Joshua Rondon and my partners are Christopher Pena and Darlin Soriano. I will show you my 5 facts.


1)Antarctica is the coldest,windiest,highest, and driest continent on planet earth.

2)Antarctica is a desert even though it holds 70% of the world fresh water.

3)The annual show accumulation across much of east antarctic adds up to less than two inches of rain.

4)This is actually comparable to Sahara desert.


5)in wintertime the sea ice around Antarctica grows at the rate of 40,000 squares miles a day.

Definition of Important Ecosystems Concepts:

Ecosystem:

A biological community of interacting organisms and their physical environment.

Population:

All the inhabitants of a particular town, area, or country.

Community:

A group of people living in the same place or having a particular characteristic in common

Niche:

A term describing the relational position of a species or population in an ecosystem

Biome:

A large naturally occurring community of flora and fauna occupying a major habitat


Antarctica's population is very difficult to account since the number is very small and varies during the year. Antarctica has a permanent human population of zero because nobody own Antarctica.
Antarctica is the southernmost continent on earth and it's surround by the southern ocean. Antarctica is bigger than Europe and almost double the size of Australia. Because Antarctica experiences such little rain, Antarctica is considered the driest place.

Research Question: How does changing the pH of the H2O2 affect catalase activity?

Background Paragraph: Catalase are enzymes, therefore they are proteins, and have specific folds in its polypeptide chains due to the hydrogen bonds between R- groups. When the pH is changed, the level of H+ ions in the environment is also changed and can affect the hydrogen bonds. Since catalase is an enzyme, it is expected to have an optimal pH where activity will peak. As the pH deviates away from this specific range, catalase activity will decrease. Since catalase is found in the liver, which is a neutral environment, its optimal pH level is around the pH of 7.

Hypothesis: When decreasing or increasing the pH level of the H2O2 from a pH of 7, and therefore changing the environment of catalase from its neutral state, catalase activity will decrease.


Variables:

Variable
Type
How it will be tested
pH of H2O2 solution
Independent
We will use pH buffers to alter the pH of the H2O2 solution to the desired ph of {3,5,7,9,11}.
Time for potato pulp to float to the surface of the H2O2 solution
Dependent
Using a stopwatch, we will start the timer when the pulp is added and stop when the potato pulp reaches the top. We will measure the time it takes for the potato pulp to reach the top
Mass of potato pulp
Constant
Weigh the 2.0 grams potato on a digital scale. We will weigh each sample to ensure that each trial and condition uses the same mass of potato pulp.
Volume of H2O2 solution
Constant
Using a graduated cylinder, we will measure exactly 15 mL and then transfer it to the test tube. For every trial and condition, the volume of the H2O2 solution will remain the same.
Substrate concentration
Constant
The concentration of the H2O2 will remain constant by using the stock solution of H2O2, which is 6% H2O2.
Volume of Test Tubes
Constant
We will use test tubes of the same volume (35 mL) and the same height, in order to maintain the height that the potato pulp rises constantly.
Temperature of the H2O2 solution
Constant
The temperature of the solutions would remain constant at room temperature which is approximately 27°C.
