Scientific methods stepsIn the video on, there are some scientific methods which are given by the scientific specialists. They include David Babb who is the aquatic biologists, Mark H. Smith who is a biology teacher, Sandra W. Clifton who is research instructor in the school of medicine at Washington University. Glenn W. Storrs the curator of the vertebrates paleontology in Cincinnati museum center and Maria Ghirardi who is biochemist at national renewable energy laboratory, Co. David Babb gives the first step to be taken in the scientific problem is by asking some question about it (00:09). Mark H. Smith adds that the first step to be considered is making some observations or the observation about what is investigated (00:31). The second step he gives is by asking some questions about the view and the information gathered. Sandra W. Clifton says that hypothesis formed as the third step as a tentative description of the observation (01: 16). Glenn W. Storrs gives the fourth step that the testing of the hypothesis is another essential thing to do for the predictions of the products (01:50). He adds that the data is analyzed and the raw conclusions are drawn. In this case, the hypothesis is supposed to be rejected, accepted or modified. The final stage is given by Maria Ghirardi who states that the reproduction and collaboration of the experiment are done up to whereby there are no discrepancies which exist between the theory or peer reviews and observation (2:23). These steps are critical in the scientific method as its foundation of science she adds.Challenges faced by the scientists in their researchIn the second video, there are some challenges that scientists pass as they collect the data. As seen in the video, the terrain is challenging through which they pass through hilly and rocky grounds leading to a lot of tiresome. The transportation means are very challenging through some of them uses donkeys for carrying of the pack basics. The laptops and data recording devices may need a power supply which becomes another challenge on where to get it. There is a challenge on shelter through which they sleep in tents and food cooking mechanism is not to the standards. In the problem of transport, the researchers are using donkeys for the transportation of their packs and belongings. The researchers can use this research for future reference of the place in future where some changes could occur in the same area. The research data is evidence for the state of the site in future.PseudoscienceMythical Creatures is the type of pseudoscience of having the beliefs that elves, fairies, gnomes, and pixies exist (Moir, 2015). It is based on earth believes, and there is no proof of it, and therefore they are not scientific facts (Ladyman, 2013). A person with diabetes is another pseudoscience which is not in the book but involves believing on some curative method for all mental types of disorders (Vuksan & Sievenpiper, 2015). They include dealing with a relationship that exists between the body and mind.ReferenceLadyman, J. (2013). Toward a demarcation of science from pseudoscience.
