The Combustion of Fireworks

By: Aidan Ryder

Why have fireworks been so valued for so long? They are a perfect way to start a new year, celebrate a special event, and more. In America, they are mainly used as a light show towards Independence Day on July 4th, the day that the Founding Fathers accepted the Declaration of Independence. With fireworks, the main reason, as stated before, is light. The massive light show with fireworks are stunning to the naked eye. In this blog, I will explain how fireworks truly work.

The main product of fireworks are heat and light. How are they formed? Well, they are formed through combustion. Combustion is rapid chemical combination of a substance with oxygen, involving the production of heat and light. When fireworks explode, heated chemicals react with oxygen and then produce heat and light. The electrons gain lots of energy from the heat, causing them to light up.

What is in the fireworks that cause them to be so bright and colorful? The main ingredient in fireworks are potassium nitrate. The potassium nitrate, when heated, gains lots and lots of energy, making the firework give off a lot of light. The potassium nitrate takes up approximately 75% of the firework. Next, there is charcoal and/or sulfur. These two parts act as the fuel for the firework. They help provide enough heat for the firework to explode. The last, and one of the most important ingredients, are the chemicals that cause the light to change color.

Why are fireworks so astounding? They are a bright burst of light that many people have no clue on how they work. Most people don't want to know how they work and they just care about watching them. They act as a form of celebration for almost everybody in the world. But what will happen to them? Will there be a new and improved way of celebrating good times, or will it just stay the same? I believe that, in the future, there will be many new ways on how fireworks are made. I believe that they will continue to use current ways, but new ways of fireworks will be invented in the future. There could be shapes drawn out in the sky and

Force and Motion in Concerts

Force and Motion Blog  By Amadi Clemens INTRODUCTION: Do you listen to Travis Scott? If so, you know of his most recent album AstroWorld has been on tour. One of his recent shows (in Oakland, California) he performed with a roller coaster. Crazy, right? It wasn’t like a full roller coaster that you see Six Flags. It’s like the Ring of Fire at Clementon Park. His ring ties into his theme park theme! PROS AND CONS: There are pros and cons that follow this event. A pro is that it was a fresh idea. I’ve seen amusement parks and rides in music videos but never live in concert. Another pro is that it was eye-catching and entertaining.. The main idea of a concert is that it is entertaining, this is going back to the idea of fresh. A con is that it’s very dangerous. Although thrilling, what if something goes wrong? What if it breaks? What if it stops mid-way in the year and he can’t rap anymore? Mechanical service would have to come and get him and that can ruin the concert. Another con, what

Chemical complexities that causes Saturn's rings to change planet’s atmosphere

Ayad Alhazmi 10/19/2018 Chemical complexities that causes Saturn's rings to change planet’s atmosphere New discoveries are made today on Saturn's rings by the Cassini space probe. Based on data from the final orbits of NASA's Cassini space probe shows the rings of Saturn. Some of the most amazing celestial objects in the universe are far more chemically complicated than was previously understood by scientist. When the Cassini space probe first gathered the information from 2017 and the signals of Cassini took scientist a long time to retrieve the information. Also knowing the astrophysicists are still studying it is beyond my reach. I will show you a quote by a professor of physics and astronomy Thomas Cravens. "Two things surprised me. One is the chemical complexity of what was coming off the rings -- we thought it would be almost entirely water based on what we saw in the past. The second thing is the sheer quantity of it -- a lot more than we originally expected.

The Earth is a very big Magnet Its North and South Poles are Highly Magnetic

The Earth is a very big Magnet     Its North and South Poles are Highly Magnetic   By: Alzahraa Alrubaiey Magnetism is the force exerted by magnets when they attract or repel each other. Magnetism is caused by the motion of electric charges. Earth has two geographic poles: the North Pole and the South Pole. They are the places on Earth's surface that Earth's imaginary spin axis passes through. Our planet also has two magnetic poles: the North Magnetic Pole and the South Magnetic Pole. The magnetic poles are near, but not quite in the same place as the geographic poles.   The Earth is a magnet that can interact with other magnets in this way, so the north end of a compass magnet is drawn to align with the Earth's magnetic field. Because the Earth's magnetic North Pole attracts the north ends of other magnets, it is technically the South Pole of our planet's magnetic field. A compass point north because all magnets have two poles, a north pole
