Recommended: Essay on scientific method and its necessity
A scientist wants to learn and discover the untold secrets of our world and universe. To “do” science there needs to be evidence for the scientist to evaluate and study. If you take apart the study of science there is one thing at the foundation and that is evidence. Without it, science would be only guess work. Scientists follow the rules and guidelines of science and use their senses to study evidence. A person does not need to be declared a scientist by a university to be one. To be a scientist one has to be interested in and devoted to finding answers to unanswered questions about some aspect of science, and want to contribute new knowledge to the discipline of science. Jacques Cousteau was not technically a “real” scientist. He did …show more content…
This is the formal scientific method, even though almost every scientist uses a different version of the this method. Questions are always flowing around scientists’ brains, especially when they're making observations and thinking about their work. They are observing and asking questions and developing different hypotheses about what results they will get if they change aspects of their experimental procedure. Scientists do not make a conclusion regarding their hypothesis until it is proven right or wrong from their data and observations.
Some people say theories are just a good hunch, but the difference between theories and hunches is that a theory is based on facts and evidence and can be proven true or false and a hunch is just a feeling that something is a certain way. Scientists may get hunches, but they develop hunches into hypotheses that, in turn, are proven to be true or

The diver would have a full suit and helmet on, which was very heavy making movement very restrictive for the diver. The closed-circuit means air was continually flowing causing air to be wasted, which led to a much shorter time limit in the water. In 1947, using the Aqualung, Cousteau set a world's record for diving, reaching a depth of 300 feet. He also invented a unit that teams of scientists could live in under the sea. He called them Conshelf l, Conshelf ll and Conshelf III. In addition to these inventions, he advanced the technology of underwater cameras, which helped him to document all kinds of animals deep underwater that people had never seen
The overall goal of science is to be able to gain an understanding of the phenomena being studied by conducting different scientific investigations that create knowledge that qualifies one or more of the three levels of understanding.
One would think that science is methodological. After all, the sole purpose of science is to discover universal truths. There are practices meant to remove any bias, such as peer review, repeatability studies, and a hard reliance
In science, a theory will refer to an explanation of an important feature of the world supported by testing and facts that have been gathered over time. It’s there scientific theories that allow scientists to make predictions about untested and unobserved concurrences in the world. The American Association for the Advancement of Science has this explanation of what a theory means to those in the science field, and it is as follows, “A scientific theory is a well substantiated explanation of some aspect of the natural world, based on a body of facts......Such fact supported theories are not guesses but reliable accounts of the real
First, when observations are made, hypothesises are formed. To test these hypothesises scientists conduct experiments. If their hypothesis is right, it is confirmed by further experiments and validated by other scientists. After many experiments and confirmations, a theory is formed. A scientific theory is a broad and general idea or explanation provided by scientists and is related to observations and is supported by a large amount of evidence. A theory is not a fact however it is just a possible explanation. An example of a theory is the Big Bang Theory.
There are many definitions to theory. According to Akers (2009) “theories are tentative answers to the commonly asked questions about events and behavior” (Akers, (2009, p. 1). Theory is a set of interconnect statements that explain how two or more things are related in two casual fashions, based upon a confirmed hypotheses and established multiple times by disconnected groups of researchers.
The scientific method is the analyzation of evidence, to examine a case from every angle possible, to not give up on an investigation until all of the angles are covered and to not allow personal emotions create a bias in their mind (Osterburg 2010). A scientific method example would be when an investigator arrives to a crime scene, they would first search the area for clues and see if something doesn’t seem right. Next they would have to search for different forms of evidence, most important would be trace evidence because it can provide DNA evidence which can also link a suspect to the crime. There are many more ways evidence and other clues can be harvested from a crime scene but it is up to the investigator to use their knowledge and help find the person responsible for the crime

The book is not providing explanation on what scientists did or how they did it. However, it offer explanations on how scientists think and how they make conclusions. In addition to the many topics explored, it is worth noting that there are also interesting tales behind some big discoveries in science which are an added attraction to this book. The Author, Dr Samir Okasha, a professor of philosophy of science at the Bristol University states that his aim of writing this book was to pass the philosophy of science in a way that can be understood by everyone. He also sought to pass his ideals in a manner that is free from complicated Jargon, with real world examples to enable all readers understand and

The revolution brought about many radical changes and ideas that helped to strengthen it and the scientists that helped to bring it about became significant persons in history. "The emergence of a scientific community is one of the distinguishing marks of the Scientific Revolution."2 It was this form of community that gave a foundation for open thinking and observing throughout the sixteenth century and through twenty-first century. It was the first revolution that had more of a dedication to the ongoing process of science than of a goal to achieve scientific knowledge.3
Science is the observation of natural events and conditions in order to discover facts about them and to formulate laws and principles based on these facts. Academic Press Dictionary of Science & Technology --------------------------------------------------------------------- Science is an intellectual activity carried on by humans that is designed to discover information about the natural world in which humans live and to discover the ways in which this information can be organized into meaningful patterns. A primary aim of science is to collect facts (data).
Science is the body of organized knowledge. Science is the collection of ideas and theories and the methodology used by people to prove them. It is the set of methods that people follow in order to explain the things that they see, the things that they perceive and the things that they believe in.
A scientific theory is an explanation that is well- substantiated explanation in regards to some aspect of the natural world that is attained through scientific method and is tested numerous times and usually confirmed through vigorous observation and experimentation. The term theory can be seen as a collection of laws which allow you to show some kind of phenomenon. The strength of a scientific theory associated with the diversity of phenomena can explain its elegance and simplicity. However when new evidence is gathered a scientific theory can be changed or even rejected if it does not fit the new findings, in such cases a more accurate theory is formed. Scientific theories are used to gain further
Science is about understanding and building knowledge about how the natural world works. It explains the inter-relationship with one's life and nature and promotes environmental education and more so environmental habits. Science teaches us as learners’ important skills such as reasoning, problem solving, analyzing, predicting, etc. It builds a foundation by providing a base in case a child does not go to higher level of education. Since science is all around us it is important to teach it so that the children could learn about themselves and their environment. Science also provides the knowledge needed to create new pieces of technology, which scientists used to develop civilization. For example, rather than writing
The steps that are included in most pre-college textbooks are defining the problem, gathering background information, forming a hypothesis, making observations, testing the hypothesis, drawing conclusions, and communicating the results, but this method is not used. One reason for this myth is the way results are published in research journals because it makes people believe that scientists follow a certain research plan. Philosophers have shown that no research procedure is applied by all scientists. Usually scientists use imagination, knowledge, perseverance, and other methods used by problem solvers. This myth teaches that science is not different from other challenges that humans face. This myth has a chance to be corrected because many newer textbooks are taking the method out of the discussions of
