VIDEO 1 REVIEW: INTRODUCTION
Biology is the study of life, and there are four main ideas in the field of biology: Evolution, Free Energy, Information, and Systems. Evolution has five main concepts including natural selection, small sample size, non-random mating, mutations, and immigration & emigration. Contrary to popular belief, Darwin did not “invent biology” rather he created a way to explain natural selection, and defined Biology as “the tool that allows organisms to become better adapted to their local environments.” He also believed that all life shares a common ancestry, otherwise known as macroevolution. Free energy is the energy that is available to do work. The energy flowing from the sun to the earth, which is used is by plants for photosynthesis and respiration is such energy. Homeostasis, which is the maintenance of a strong internal environment, is key in dealing with free energy. Information is the importance of DNA and cell communication. DNA is what makes RNA and is located in the nucleus, and the RNA makes proteins, which are used to build organisms. Lastly, cell communication is cells transferring information whether using hormones or nerves. Biology is built on hierarchies of systems, such as carbon compounds, macro molecules, organelles, cells, tissues, organs, organ systems, and so on.
VIDEO 2 REVIEW: SCIENTIFIC METHOD Scientists, as well as anyone who is interested in seeing how something in the world works use the Scientific Method.
There are four main characteristics of the scientific method: observation/measurements, make an assumption, test the assumption, and revise the assumption. The first stage we make an observations. For instance, I notice that my peppers in my garden are not growing well. I am going to assume this is because I did not water that area well enough. So I am now going to test my assumption. This is done by watering the peppers in my garden more frequently. Lastly, I am going to see if my assumption was correct. If my peppers only needed more water, they will begin to grow more rapidly. It is also possible that my assumption was wrong, and that my peppers were getting enough water; however, there could be something wrong with the soil, temperature, etc. These are the four main characteristics of the scientific method; it is important to note that our assumptions sometimes be wrong, thus it is always important that we test our assumptions to make sure we are correct.
Scientific Method: The scientific method is a method or procedure that uses precise measurements, predictions, and data to answer questions.
The development of the scientific method in the late 1500’s to the early 1600’s was a crucial stepping-stone in the science community. The scientific method is based upon observations, hypotheses and experimentation. The concept is rather simple, and can be applied to many areas of study. Once an observation is made, the observer can make a hypothesis as to why that phenomenon occurs and can then design an experiment to prove whether or not that hypotheses is valid. Although the scientific method has been extremely useful in the discovery of various things from usages of medications to studying animal behavior, there are still those who question the usage of this tool. These critics claim that since
The scientific method is a process that is used to answer questions and solve problems. Although there are different variations of the scientific method, it contains 5 basic steps. (1) Recognize a question or an unexplained occurrence in the natural world. Once this question has been developed examine scientific literature to determine what is already known about the subject matter. (2) Develop a hypothesis. A hypothesis is
The scientific method is used during experiments to find a conclusion and or reason as to why an event or something happens.
We discover scientific knowledge in various natural science fields such as biology or chemistry. A common misconception about the natural sciences is that both the knowledge they reveal to us and the scientific method used in discovering this are purely analytical. This means that these sciences are rigid in facts and do not contain any subjectivity or creativity. However, the scientific method is not a rigid system of pursuing measurable facts. It contains fallacies and biases. In testing hypotheses, performing observations, or reasoning inductively, science is undoubtedly flawed and erroneous. Paradigms, commonly seen as infallible and containing rather insignificant errors, contribute to many of the errors involved in scientific
The scientific method continues to be misrepresented in public schools all over the world. Students are being taught that there is a beginning and an end to the scientific method, and that everything in between is protocol and must be followed chronologically. “Ask a question, do some research, come up with a hypothesis, conduct an experiment, understand your data, make your conclusion!” a grade six science teacher will tell their students. “It’ll be on your quiz!”. However, what those students are not being taught is that the scientific method has never been, and will never be a linear process. Scientists constantly revisit different steps of the process in order to better understand the subject matter; sometimes it can take many years to
The Scientific Method is the approach that scientists use to investigate some phenomena. It’s a standard technique to find cause and effect of a particular problem.
The scientific method is a process for experimentation used to explore observations and answer questions. It is used unconsciously by many on a daily basis and understanding how to apply the method can be valuable in making decisions and solving problems. For this assignment, I have chosen to use the scientific method to demonstrate how to organize my cluttered apartment to fit two storage units thus eliminating two bills and lowering my debt.
The Scientific Method is the standardized procedure that scientists are supposed to follow when conducting experiments, in order to try to construct a reliable, consistent, and non-arbitrary representation of our surroundings. To follow the Scientific Method is to stick very tightly to a order of experimentation. First, the scientist must observe the phenomenon of interest. Next, the scientist must propose a hypothesis, or idea in which the experiments will be based around. Then, through repeated experimentation, the hypothesis can either be proven false or become a theory. If the hypothesis is proven to be false, the scientist must reformulate his or her ideas and come up with another hypothesis, and the experimentation begins again. This
Knowledge can be produced using a variety of different methods. However, in the natural sciences sense perception through observation is used primarily. This can be seen through the work of researchers who often observe the results of experiments and trends in order to analyze different phenomena and perspectives. While there are many scientific methods based on scientific thinking using logic and predictability, the idea that
Have you ever wanted to think like an expert on whatever you do? How about learn from the most intellectual scientists’ mistakes? Whichever you want to do, you have to do with one very easy method: the Scientific Method. The Scientific Method comes in seven easy steps- observing, asking questions, forming and testing a hypothesis, analyzing results, concluding your experiment, and telling others about it.
from the class “The Scientific Method and How Science Works”, I understood that scientific method is the basic of all scientific experiments, then I learned six steps of it. I also learned the difference between observation and hypothesis, which has a great contribution to my understanding of geology principles. When I see the steps of the scientific method, I think it is quite similar with the hypothesis testing model in my statistic course. It is also connected with the rejection and acceptation of the hypothesis that I have learned in the commercial courses and the similar processes are applied in the scientific method!
The origin of life has been questioned by men for thousands of years. Scientist have studied the universe extensively and developed various theories to answer questions related to the origin of life. Questions like, how did life begin? Is the universe the result of chaotic chance or intelligent design? How did life on earth come to be? These are some of the many questions scientist work hard to solve, but what does their research tell them? Let’s start with the well-recognized theory of evolution.
Biological evolution is the name for the changes in gene frequency in a population of a species from generation to generation. Evolution offers explanation to why species genetically change over years and the diversity of life on Earth. Although it is generally accepted by the scientific community, Charles Darwin’s theory of evolution has been studied and debated for several decades. In 1859, Darwin published On The Origin of Species, which introduced the idea of evolutionary thought which he supported with evidence of one type of evolutionary mechanism, natural selection. Some of the main mechanisms of evolution are natural selection, mutation, and genetic drift. The idea that all life on Earth shares a common ancestor has been around for
