Bio - Plastic to save de world

Plastic waste has always been a major problem on our planet, and the amount of plastic discarded daily is huge. To manage this issue, bio-plastics were created as a revolutionary invention. If you buy a bottle of juice and the label says 'Bio-plastic', it can degrade in weeks without leaving microplastics, the opposite with conventional plastic, which takes hundreds of years to decompose.

The algae are harvested and processed into biodegradable pellets

The biodegradable pellets are melted at controlled temperatures and shaped into bottle preforms

The preforms are heated again and blown into the final bottle design using high-pressure air.

The bio-plastic bottles are filled with the beverage and labeled with eco-friendly ink.

Finally, the packaged products are transported an delivered to consumer stores worldwide. hace menos de un minuto

*****Great invention, good job with passive. You can now add the next parts.

Revolutionary invention: Water Purification Straw

The water purification straw is a portable device that is used to clean dirty water and make it safe to drink.

First, it was created to help people who do not have access to clean water. It was designed as a simple and portable solution for rural areas, emergencies, and natural disasters where safe water is not always available.

Then, dirty water enters the straw. Next, the water is filtered by a special membrane. After that, bacteria and parasites are removed by the filter, so the water becomes safer to drink. Finally, people can drink cleaner water directly from the straw.

Before this invention was created, many people had suffered from diseases caused by contaminated water. For this reason, the invention became very important for communities that needed a practical solution.

Today, this invention is used by travelers, hikers, volunteers, and communities around the world. It is considered very useful because it helps prevent diseases and saves lives.

Everyone needs clean water, and someone in an emergency can use this device easily. Almost anyone can carry it because it is small, light, and really practical.

If people use the water purification straw, they drink safer water. If more communities use this invention, their health will improve. If this invention did not exist, many people would be at risk.

Finally, I think the water purification straw is an extremely important invention which continues to be relevant today because it gives people access to clean water in a simple and practical way. *************Great choice, good job with passive voice and description, remember to add sequencing words for the process. You can now add the next parts. *************Hello teacher, thank you for your feedback. I added sequencing words to explain the process better, such as first, then, next, after that, and finally. I also started to include the next parts of the project: historical context, impact, relevance today, conditionals, and relative clauses.

THE ATOMIC BOMB

The atomic bomb was developed during World War II as part of the Manhattan Project. Before the bomb had been created, scientists had studied nuclear energy for many years. It was first used in 1945 on Hiroshima and Nagasaki, which changed history forever.

The atomic bomb works through a nuclear reaction that releases a huge amount of energy. Uranium or plutonium is used to produce an extremely powerful explosion. The energy that is generated can destroy large areas in seconds.

Millions of people learned about the destructive power of nuclear weapons after World War II. The atomic bomb, which was one of the most revolutionary inventions of the twentieth century, changed military strategies around the world. Many countries started nuclear programs that were developed for defense purposes.

Today, atomic weapons are still maintained by several countries. Everyone knows that nuclear weapons can be very dangerous if they are used irresponsibly. However, the technology that was developed for the atomic bomb has also been used in nuclear power plants, which produce electricity for millions of people.

The atomic bomb is an invention that changed history forever. Although it was created for war, its technology continues to influence today's world in different ways.

The first smartphone was developed by IBM in 1992, but the modern concept was revolutionized by Apple in 2007.

First, everything started with the ideation phase. Before the engineers built the physical device, designers had sketched multiple concepts and software developers had planned the operating system interface. Once they finalized the blueprints, the team created the 3D models.

Next, the supply chain department sourced the raw materials and hardware. After the company had secured contracts with specialized suppliers for the processors, camera sensors, and batteries, factories manufactured the main circuit boards (PCBs) and the glass displays.

Then, the assembly process began in high-tech facilities. Before robotic arms and workers put all the pieces together into the aluminum or plastic chassis, technicians had tested each individual component to ensure quality.

After that, the devices received their digital brains. Once the software team had flashed the operating system into the internal storage, quality control experts ran rigorous stress tests on the hardware and software.

Finally, the product was ready for the market. After the marketing team had designed the boxes and manuals, logistics workers packed the smartphones and shipped them to stores worldwide.

1- Facebook was created in 2004 by Mark Zuckerberg

2-Today, a personal profile is used to connect with family and friends.

3.Every day, many photos and videos are shared on the app.********* You need to add sequencing words and more description.

Past Simple and Past Perfect

History: Before 2004, people had used old websites. Zuckerberg had to work through problems before Facebook came back better.

Impact: Facebook had already changed everything. People who had lived through long distances used it to get away from routine and keep away from old mail.

Conclusion: When we look back, it had become the biggest network. - Facebook is a website that connects friends

Facebook, which is a very old social network, is still free.

Invention of history : Airplane.

The airplane is designed through of the use of software specialized(specialized software), when there are defined the shapes (wing, fuselage, motors). Each piece is evaluated by a team of experts to ensure its safety and efficiency.

Lightweight and durable materials such as aluminum, titanium and carbon fiber are used to create one thousands of pieces in different factories; then, the main parts of the airplane are assembled whit(with) high pressure using special rivets and screws. Later, electrical, hydraulic, navigation, and communication systems are installed as well as motors and the interior of the cabin (seats, lighting, restrooms, etc.).

followed by the airplane is undergoes(it undergoes/ not clear) rigorous performance tests and finally, flight tests are conducted, and then the airplane is delivered to the airline. ********** Great choice, the airplane is an interesting and complex invention. You did a good description and correct use of passive,however don't forget sequencing words. You can continue with the next advances.

the airplane had been the invention revolutionary because it changed the way how the people to travel

You can now add the next parts.**************

I can't imagine come(coming) back on the 20th (century), when It(they) hadn't color TV, the nights must have been boring.

In this moment reminder( I remember), when I was child my Grandma have(had) a color TV more old(older Tv or very old Tv), so I was the remote control, but I had a lot o fun when all family saw the TV together, I watched the World Cup of soccer

**********************

The color TV, which in the 1920s was not thought that it could display anything like it, has been one of the most innovative inventions that has allowed to reach the Smartphone

Before modern electricity was developed, ancient people had observed that rubbed amber attracted small objects. Later, Benjamin Franklin conducted the kite experiment and proved that lightning was a form of electricity. Scientists had studied electrical charges before Alessandro Volta invented the first battery in 1800. His invention provided a continuous source of electric current. Researchers had made important discoveries before Michael Faraday developed electromagnetic induction. Finally, Thomas Edison improved the practical light bulb in 1879 and brought electric lighting into homes. These advances changed the way people lived and used energy.
