You know the invention of the air pollution cleaning tower , made by Angad Daryani , don't you? It is a very usefull invention for the pollution of Mumbai , India.

The story began when Angad Daryani grew up in Mumbai , India , he suffered from asthama caused by the polluted air. Because of the problem , three million people die each year. At the age of 19 , he invented the air pollution cleaning tower that is 6.1 meters.

I notice that the air pollution cleaning tower is too big for a small house. So I hope Angad Daryani will invent a smaller air pollution cleaning tower.

Thank you for listening my presentation. Hope you enjoy it. Bye bye!

There were about 1.3 billion cars in use worldwide in 2016. When it was first introduced, the automobile was considered an environmental improvement over the horse. Before its introduction in New York City; over 10,000 tons of manure were added to the streets every day. However, in 2006, automobiles were one of the leading sources of air and noise pollution and health problems worldwide.Karl Benz is the first person to invented the first car so I was very admired him! I will learn him to invent something. By Hoang Anh

You now Electricity wasn’t exactly "invented" in the traditional sense; rather, it was discovered and harnessed through the work of many scientists over time. The Rise of Electric Power – Thomas Edison & Nikola Tesla.Do you now ,As scientists such as Benjamin Franklin, Alessandro Volta, and Michael Faraday made discoveries about electricity, they found practical ways to generate and use it. For example, Volta's invention of the battery in 1800 demonstrated that electricity could be created chemically, and Faraday's work led to the development of electric motors and generators.Electricity became especially useful during the Industrial Revolution, where it offered a more efficient form of energy for factories, transportation, and communication. The invention of the electric light bulb by Thomas Edison, along with the development of electric power grids, made electricity accessible to homes and businesses, improving quality of life and revolutionizing society. thank you for the listening. I hope you enjoy it bye-bye.

In the past, mobile phones were merely tools for making calls and sending messages. However, with rapid technological progress, smartphones have emerged with numerous modern features. We can access the internet, take photos, record videos, play games, study, and work remotely. As a result, mobile phones not only connect people but also contribute to the development of various fields.

Despite their advantages, excessive phone usage also brings many negative effects. Many people spend too much time on their phones, which affects their health, studies, and work. Therefore, we need to use mobile phones wisely to maximize their benefits.

Mobile phones are an important invention that helps us stay connected and progress in life. However, using them in moderation will allow us to avoid negative impacts and fully enjoy the benefits they offer. My project is end here. Thank you for looking at my project! 😃😃😃

• Early Concepts: Before the iPhone, Apple was already well-known for its innovative products like the iPod, which revolutionized music consumption. However, Apple's founder, Steve Jobs, had a vision for a device that would combine a phone, a music player, and an internet device into a single, user-friendly package.

• The Birth of the Idea: In 2004, Jobs began thinking about how to integrate a phone and iPod into one product. Apple also wanted to push the boundaries of user interaction. Jobs was inspired by the growing touch-screen technology, which led to the idea of creating a device that would rely solely on touch to control all its functions.

• Development: Apple worked on the iPhone in secret, codenamed "Project Purple." The device combined cutting-edge hardware with software developed by Apple engineers. The iPhone's interface was built around a multi-touch screen, which was revolutionary at the time. This allowed for intuitive gestures like pinching, swiping, and tapping.

• The Big Reveal: The iPhone was first unveiled by Steve Jobs on January 9, 2007, at Apple's Macworld conference. Jobs famously announced: "Today, Apple is going to reinvent the phone." The crowd was captivated by the sleek design and the device's ease of use, setting the stage for a revolution in mobile phones.

• Release and Impact: The first iPhone was released on June 29, 2007, exclusively through AT&T in the United States. The iPhone's success was immediate, with long lines forming at stores around the country. It introduced features that would become industry standards, including a touchscreen interface without physical buttons, an App Store (introduced a year later), and integration of internet browsing, email, and media in one device.

• Subsequent Models and Evolution: Over the years, Apple has released multiple iPhone models, continuously improving its features, cameras, performance, and design. The iPhone became a cultural phenomenon, creating a whole ecosystem of apps and services, shaping the smartphone market, and even influencing other industries and they are now our phones today.thank you for listening and goodbye

  
  

Introduction:

• Opening Hook: "Imagine a world where human flight seemed as impossible as walking on the moon. Yet, less than 120 years ago, two determined individuals proved that we could fly."

• Set the Stage: Introduce the common belief that flight was a dream for centuries, with humanity trying (and failing) to achieve it through mythology, early science, and experiments.

• Thesis: "In 1903, Orville and Wilbur Wright made that dream a reality, changing the course of history forever. This is the story of their invention, the airplane, and how it forever altered the way we understand the world."

Section 1: The Dream of Flight

• Historical Context: For centuries, flight was seen as an unattainable goal. From Leonardo da Vinci’s sketches to the myth of Icarus, humankind dreamed of soaring above the earth.

• Challenges of Flight: Early experiments with hot-air balloons, gliders, and wingspans showed that the principles of flight were understood, but the ability to control and sustain flight was elusive.

• Key Players Before the Wrights: Mention pioneers like Sir George Cayley, Samuel Langley, and Octave Chanute, whose contributions laid the groundwork.

Section 2: The Wright Brothers’ Breakthrough

• Who Were the Wright Brothers?: Discuss the Wright brothers’ background. Emphasize that they were not trained engineers or aeronautical experts, but bicycle mechanics with a passion for solving practical problems.

• The Wright Brothers’ Process: Highlight their scientific approach — experimentation, rigorous testing, and a deep focus on control and stability.

  • Unlike others who were focused purely on getting a plane off the ground, the Wrights concentrated on controlling it once airborne.

  • Their development of wing-warping (a technique to control roll) and the creation of a reliable engine set their plane apart.

• The 1903 Flight: On December 17, 1903, in Kitty Hawk, North Carolina, Orville piloted the Flyer, marking the first powered, controlled flight.

  • Show how it wasn’t just about the first flight itself, but about proving that flight could be sustained and controlled.

Section 3: Innovation Beyond the Wright Brothers

• Building on Success: Although the Wright brothers were pioneers, the evolution of the airplane didn’t stop with them. Engineers and aviators from around the world built upon their discoveries, leading to:

  • The development of more powerful engines.

  • Improvements in materials and aerodynamics.

  • The growth of commercial aviation, especially post-World War I.

• Impact on War, Travel, and Technology: The invention of flight transformed the battlefield, sped up global travel, and revolutionized industries from agriculture to communications.

Section 4: The Cultural Shift

• The World Changed Forever: The Wright brothers’ invention shifted humanity’s perception of its place in the world. Airplanes connected people and places, making what once seemed remote accessible.

• Legacy and Inspiration: Discuss how the Wright brothers’ story continues to inspire inventors and innovators today, reminding us that the pursuit of seemingly impossible dreams is worth the risk.

  • Modern aviation and space exploration owe much to their legacy, as do fields like renewable energy (think of how wind turbines work on the same principles).

Conclusion:

• Closing Thought: "The Wright brothers were not simply inventors of a machine, but pioneers of possibility. They proved that human determination, curiosity, and a willingness to fail could create something world-changing."

• Call to Action: Encourage the audience to think about what the "impossible" dream is for them today. What are they working on that might change the world in the future, just as flight changed ours?
