We all say that teamwork makes the dream work and that is also true for science. Each scientist can only master one field of science so if they want to research for something news in science like the discovery of a new element on Earth, creates a new technology product, they need to work together.  Some complex research problems will require collaboration between scientists because they would bring up a different way to approach the problems and also pieces of knowledge from their field to help solve the puzzle.  Communication will help them organize the idea and create a step by step plan for them to achieve their goals.

Scientist need collaborate with others scientist to have a higher effects on science. Because Scientists must give talks, write papers and reports, communicate with a variety of audiences, and educate others. Each scientist can only master one field of science so if they want to research for something news in science

Collaboration and communication are important elements in all works, not just science. Therefore, collaboration and communication are very important in science. When scientists collaborate and communicate with each other, they can come up with discoveries, new inventions, and new results. They combine, using their knowledge, their genius brains to produce desirable results. At the same time, when they work together, the likelihood of achieving successful results will be higher than what one person does.

# data[].attributes.body
Even though the boundaries between different subjects in science are not very firm, but science was categorizing into many topics. Due to the majority of knowledge, collab and communication must happen to research about a hypothesis. A hypothesis could involve physics and also chemistry, but Physics could be about Quantum Physic and Energy; Chemistry could also be about Quantum Chemistry and a lot more. So cooperation and communication could share the information and knowledge,exchanging ideas. Base on that, the scientists could fasten up their research and experiment.

# data[].attributes.body
Collaboration and communication help scientists to exchange ideas, learn more, and back up for each other. 1 tree is nothing, but 3 aggregate trees build volcanoes and that is exactly the meaning of collaboration. With collaboration, experiment can be more thoroughly carried out in less amount of time and efforts but still bring efficiency compared to a single scientist doing alone. Communication helps scientist to convey their ideas, theirs thoughts, as well as expressing their feelings. Moreover, when communicating with others, scientists’ mouths operate frequently so that they will not become mute after their prolonged experiments.

# data[].attributes.body
Both collaboration and communication are really crucial for scientist. One of the most famous project is the genome project, which was an international scientific research project to determine the base pairs that make up human DNA, and also identifying and mapping all of the genes of the human genome from both a physical and a functional standpoint. It was and still the world's largest collaborative biological project. The result was phenomenal. It has the application to many fields, from molecular medicine to human evolution. This achievement proves that collaboration and communication are really important for science, for when the world is united, we can achieve even the craziest thing.

# data[].attributes.body
Scientists must give talks, write papers and proposals, communicate with a variety of audiences, and educate others. Thus to be successful, regardless of field or career path, scientists must learn how to communicate. Moreover, scientists must learn how to communicate effectively. In other words, to be a successful scientist, you must be an effective communicator. It allows them to write better and more comprehensible research papers. It also allows them to be better teachers and mentors for next-generation scientists.

# data[].attributes.body
Scientists must collaborate and work together for the good of the experiment. Collaboration will bring different knowledge, different people to solve the problem. Working as a group can be hard, but it can be also rewarding. Communication is also important in science. The scientists communicate with each other, face to face or by e-mail, and phone. They can share their idea and knowledge to contribute to the experiment.

# data[].attributes.body
Communication and collaboration  is a part of sciencetist's everyday life. To be successful, regardless of field or career path, sciencetist must learn how to communicate effectively. Why? Firstly, effective communication means that you are likely to present your idea more clearly and concisely so that others can understand. Secondly, being able to communicate the relevance and impact of their ideas can enhance scientists' ability to find a job or secure funding

# data[].attributes.body
Both collaboration and communication are important in science. Teamwork allows scientist to fasten their progress and expand their knowledge. With strong communication, they will be able to keep up the work data and connections between each scientist.

# data[].attributes.body
Communication and collaboration are very important in science because they increase the chance of a successful outcome. When a phenomenon is studied by different people, there will be different opinions. Thus, scientists could work together and conduct multiple experiments simultaneously to hasten the process of discovery. They may also discuss to produce the most accurate conclusion to avoid misleading and distracting information. Those are some roles of collaboration and communication in science.

# data[].attributes.body
Teamwork is really important element in many subjects, and it has a large role in scientific experiment. Collaboration and communication basically mean that many scientists will work together to conduct an experiment. This will prove to be very beneficial because at the very start of the experiment, a variable of hypothesis will come up because there are now more than 1 person doing the experiment. Moreover, they can also conduct difference experiments at the same time which would speed up the experiment. Later, they can exchange data and finally conclude the experiment that was conducted. This is the role of collaboration and communication in scientific discovery.

# data[].attributes.body
By collaborating, scientists can enhance their experiments and the accuracy of their results. Each person has his or her own expertise, and also limited knowledge about different subjects. No matter how outstanding one person is, he or she still cannot be the best in all subjects. If people can work together, they can share their ideas and knowledge. They can help the others where they lack skills in or information about. That would not only fasten the progress, but also increase the accountability of an experiment. People would surely believe more in a research involving many brains rather than just one. That is reasonable considering the fact that scientists can correct others' incorrect ideas or improve the experiments in distinguished ways, and therefore, leading to a more accurate finding.

# data[].attributes.body
In science, communication and collaboration both play significant roles. The first reason is because they group scientists around the world together and increase working efficiency. By communication, they avoid repeating the same mistake when researching about the same topic, so they can put their time doing other useful activities. Also, if we use human resources correctly, everything will be finished in much faster speed than one individual holding all work to themselves. Secondly, by communication and collaboration, each changes in a research will be updated publicly in no time; people will acknowledge the intelligence faster. Science is made to satisfy humans’ knowledge and life wants; and we can only discover big things if we work together.

Currently, the environment around us is polluted, especially the air environment. There are two basic sources of air pollution:
- Source of pollution caused by nature.
- Source due to human activities.
The air pollutants created by humans such as CO, CO2, SO2, H2S, NOx, CFC (chlorocarbon), dust, ... Especially CO2, can fly into the atmosphere and creating a greenhouse effect.

I like Khang's writing

I believe Chemistry has done lots of things just like the foundation of the new virus after the many testing - The COVID 19. Chem also has other applications, which are: medicine and other chemicals. Gasoline is a mixed chemical that, after been through a process in the engine, the liquid creates a type of gas (CO2) that would harm the Earth's atmosphere; consequently, the gas led to Axis rain and the greenhouse effect on Earth's surface.

Duong's writing is awesome because it has a load of details from Wikipedia.

Major contributions to medicine have been made by chemistry. One of the most common medication is paracetamol, a common painkiller that treats mild to moderate aches, pain, and fevers (high temperature). For adults, the usual dose of paracetamol is one or two 500mg tablets at a time. Some of the brands are Disprol, Hedex, Medinol and Panadol.

I like Lien Chi's paragraph because it provides relevant and updated information.

An application of Chemistry is the birth of GMO foods. GMO foods, aka genetically modified foods, are foods that have their DNA altered using genes from other animals or plants to give them the traits that we desire. For example, people can modify a potato so that it produces less cancer-causing substances when fried. There are also some certain tomatoes that have been modified to stay fresh for longer. However, scientists are still unsure whether GMO foods can cause health issues in the long term.

We apply Chemistry in Medicine to create vaccine- medicines with antigen to treat infectious diseases. It is agreed that an infectious disease will only no longer a threat if a vaccine of that disease is created. Nowadays, a well-known and needful vaccine around the world is COVID-19 vaccine. All of the researchers around the world are together produce a vaccine for this virus. The hardest part of producing a type of vaccine is not creating the right antigen, but the amount of time it takes to confirm if that antigen is successful or not. At this point of time, Russia is the first country forming the vaccine of the COVID-19 virus.

Genetic Modified crop (is abbriviated as GM crops) is a technique that gradually improved our plant stocks. To create GM crops, scientists create a ring of DNA called "plasmid" and insert the plasmid into plant cellts. This method contains carefully selected gene, turning conventional crops into genetically modified. One of the main applications of this technology is the creation of plants that are resistant to certain diseases, herbicides,..
*Among all these writings, I choose myself. I have read all of the writings but I like the writting about the GM crop.
