Nowadays, people always rely on science technology, even though. Many people still do not understand what science really means to them. What is science? In the modern world, science plays a major role in shaping one’s view of the universe and himself. Many people know that science contains several areas, such as chemistry, physics and biology. Although there are different types of science, all science involves some form of observation or experiment, and some sort of theorising about how to explain the evidence collected. Science is one of the most effective ways to help us understand the natural world. In addition, science help us to discover what is in the universe and how does science work at the past till now. It helps scientists to know

Science has been changing every aspect of human’s lives in every centuries. In this essay, it has been chosen question one to be answered. This essay explains the model of science and how the main developments in the theory of continental drift correspond to the model. The process of science involves several layers which have been used in the model of science in every centuries. The model of science involves, testing ideas with evidence and theorising. The process of science involves many layers of complexity, but the key points of that process are straightforward.
The above diagram explains how science works today. Although some scientists would not follow the model, this model teaches people how science works. At the beginning, scientists often start to make some observations, which could separate into two part: direct and indirect observation. Also, scientists would chat among colleagues about different ideas, or gather ideas from readings. Step into part two: experimentation. Running experiments help scientists to confirm or reject their hypothesis. The evidence that scientists have collected may lead to support one of the hypothesis. …show more content…
The continental drift theory was proposed by Alfred Wegner in 1910. Some people may not understand what continental drift theory is. Simple, continental drift theory states that in the past, all the continents were joined in a super- continent, which is called Pangaea which meaning ‘all land’. In the end, Pangaea had broken into pieces approximately 200 million years ago. Since then, the pieces had moved to their present positions and they are still moving. Wagener supported his hypothesis with circumstantial evidence. He pointed out that Suess’s Glossopteris and other fossils, area of erosion apparently caused by the same glacier in tropical areas are now widely separated. In addition, the appearance of rock sequence and mountain ranges of the same age on the continents are now widely separated today as well. He also proposed a mechanism to account for the hypothetical drift. Although Wegner had listed several evidences to support his hypothesis, his hypothesis was rejected because he could not explain how the continents would have moved. From 1950s to 1970s, Wegner’s theory was slowly being tested by different scientist. After combining all the evidence, J.Tuzo Wilson, a Canadian geologist, proposed theory of plate tectonics, stating that continents did move and were divided into different plates we seen today. His theory proved that Wegner was right and it becomes the modern
