All About the United Nations

What does the U.N Do?


The United Nations came into being in 1945, following the devastation of the Second World War, with one central mission: the maintenance of international peace and security. The UN does this by working to prevent conflict; helping parties in conflict make peace; peacekeeping; and creating the conditions to allow peace to hold and flourish. These activities often overlap and should reinforce one another, to be effective. The UN Security Council has the primary responsibility for international peace and security. The General Assembly and the Secretary-General play major, important, and complementary roles, along with other UN offices and bodies.


The term “human rights” was mentioned seven times in the UN’s founding Charter, making the promotion and protection of human rights a key purpose and guiding principle of the Organization.  In 1948, the Universal Declaration of Human Rights brought human rights into the realm of international law.  Since then, the Organization has diligently protected human rights through legal instruments and on-the-ground activities.


One of the purposes of the United Nations, as stated in its Charter, is “to achieve international co-operation in solving international problems of an economic, social, cultural, or humanitarian character.”  The UN first did this in the aftermath of the Second World War on the devastated continent of Europe, which it helped to rebuild.  The Organization is now relied upon by the international community to coordinate humanitarian relief operations due to natural and man-made disasters in areas beyond the relief capacity of nationalauthorities alone.


The UN Charter, in its Preamble, set an objective: “to establish conditions under which justice and respect for the obligations arising from treaties and other sources of international law can be maintained”. Ever since, the development of, and respect for international law has been a key part of the work of the Organization.  This work is carried out in many ways – by courts, tribunals, multilateral treaties – and by the Security Council, which can approve peacekeeping missions, impose sanctions, or authorize the use of force when there is a threat to international peace and security, if it deems this necessary.  These powers are given to it by the UN Charter, which is considered an international treaty.  As such, it is an instrument of international law, and UN Member States are bound by it.  The UN Charter codifies the major principles of international relations, from sovereign equality of States to the prohibition of the use of force in international relations.

The United Nations is headquartered in New York City, in a complex designed by Brazilian architect Oscar Niemeyer and built by the architectural firm Harrison & Abramovitz. The complex has served as the official headquarters of the United Nations since its completion in 1952. It is located in the Turtle Bay neighborhood of Manhattan, on 17 to 18 acres (6.9 to 7.3 ha) of grounds overlooking the East River. Its borders are First Avenue on the west, East 42nd Street to the south, East 48th Street on the north and the East River to the east.[4] The term “Turtle Bay” is occasionally used as a metonymfor the UN headquarters or for the United Nations as a whole.[5]

The Chrysler Building is an Art Deco–style skyscraper located on the East Side of Midtown Manhattan in New York City, at the intersection of 42nd Street and Lexington Avenue in the Turtle Bay neighborhood of Manhattan. At 1,046 feet (318.9 m), the structure was the world’s tallest building for 11 months before it was surpassed by the Empire State Building in 1931.[5][12] It is the tallest brick building in the world with a steel framework. As of 2018, the Chrysler is the sixth-tallest building in the city, tied with The New York Times Building.[13]

Originally a project of real estate developer and former New York State Senator William H. Reynolds, the building was constructed by Walter Chrysler, the head of the Chrysler Corporation, and served as the corporation’s headquarters from 1930 until the mid-1950s. The Chrysler Building’s construction was characterized by a competition with 40 Wall Street and the Empire State Building to become the world’s tallest building. Although the Chrysler Building was built and designed specifically for the car manufacturer, the corporation did not pay for its construction and never owned it, as Walter P. Chrysler decided to pay for it himself, so that his children could inherit it.

When the Chrysler Building opened, there were mixed reviews of the building’s design, ranging from its being inane and unoriginal to that it was modernist and iconic. Perceptions of the building have slowly evolved into its now being seen as a paragon of the Art Deco architectural style; and in 2007, it was ranked ninth on the List of America’s Favorite Architecture by the American Institute of Architects.

Here is our Tshirt Design we have to figure sizes and order them for the project.

D75 Tech project

Our D75 Tech project:

My idea is to cut out a shape of Manhattan that will be glued to a board below with the water and bridges and of course our Statue of liberty. Here is a rough shape of Manhattan let’s discuss what will be included in our raised map. We have to build it and design it with what we want to include.


 Lets also look at some facts about the Empire State Building.

Our D75 Tech Project Intrepid June 13th

Let’s delineate exactly the perimeters of our project.

Here are our student’s impressions of our project thus far:

Malachi: Our project is about the One World Trade Center, Empire State building, Freedom tower. The Flat Iron building and the Statue of liberty. The Statue was a present from the US from France. We are creating  map of New York City and using Ozobots to travel from building to building. We are in the process of creating the building out of Lego and Puzzles.


Nayshawn: Our project is about the Freedom tower Statue of Liberty and Flat Iron building. And we are going to use Ozobots to take us through the city. The Statue of Liberty was a gift from France . We are using the Ozobots two ways we will navigate using Blockly code and the optical color code.

Secret: I think our project is about The Statue of Liberty and it history and how France gave it to us for our hundredth birthday. One France first gave it to us it was copper colored but now it is green. We are also using  Ozobots. Ozobots are like mini-cars but they use code. We are dressing them up like cabs and coding them to trade from landmark to landmark.

Tysean: Our project is about  Using Ozobots get around the city that we made ourselves of Legos, puzzles and different objects. It could get hard because we need to code the Ozobots to around Manhattan from Land mark to Land mark. Ozobots follow color coded dark lines and and use Blockly.  We will use the Ozobots to showcase The Statue of Liberty , Freedom tower and other landmarks.

Mr. Harris:

Our project  is to use Legos 3d puzzles costumes like the the Statue of Liberty and Ozobots in a mini taxi costume> Our project is to make a mini model of Manhattan and have the Ozobots travel using color code and Blockly code. The Ozobots will tour Manhattan.


Our project is about New York city . The amazing place with it’s tall buildings, law offices and cars. The World trade center is the best building It has tons of security systems and is a long as the original Twin  towers. It took 8 years to build and cost billions of dollars. I think this the project it is inspiring us to really learn about the way the history of these buildings. We are using Ozobots to code using color and block code to get from building to building.

Kaylaysha  Sanchez:

I think our project is abs the  important places in New York city.We are using puzzle legos and other things to build models of important buildings. While learning  all about these buildings. The Ozobots  represent us traveling around the city. So far we have learned about The Statue of liberty, The Freedom Tower and We will be using the Ozobots to travel from building to building.
