A subjective reasoning is based on how you feel about something more than an actual fact. A scientific thought is emotionless and based on pure facts.
I've included 3 links on Alfred Wegener's life. He died at the age of 50 in 1930. His speciality was meteorology and well published in this area. The concept of continental drift began by the observation of the close fit between South America and Africa. Fossil evidence gave some support to the hypothesis. The concept of the continents drifting for hundreds of millions of years was criticized as too radical a departure and based on scant evidence. Also, in Wegener's hypothesis was the existence of Pangaea, where initially all continents were connected. George Gaylord Simpson was a well known scientist who was highly critical of continental drift. The view to the contrary was the continents had remained fixed and it was the plants and animals that had dispersed themselves on both continents. Per George Gaylord Simpson, his paper in 1939 seem to lay a solid foundation against continental drift. Antarctica as a faunal migration route. Proceedings, Sixth Pacific Congress, 1939, p. 755-768. First of Simpson's papers that directly addresses historical biogeography. He argues that land-bridges and continental drift are not necessary to explain disjunctive distributions. "In scientific theory the best-supported and most nearly self-sufficient hypothesis should be preferred and unnecessary additional hypotheses should be rejected or held in abeyance." (See "Evolution and Geography," 1953.) It is recognized today that Alfred Wegener was way ahead of his time.
Carl Rogers made contributions to the humanistic curriculum design. This is based on the principles of humanistic psychology. He thought that the curriculum should empower students. Teachers were to place importance on students' opinions and feelings.
The fossils of animals were found the three different continents, but no animal could've swam that far across the salt water, so there had to be another way. Also, the plant fossil glossopteris was discovered in Antarctica, where no plants could live.
the role of the opinion might be the "hypothesis" of the observation or data it can also be the thought of the scientist as said the opinion. HAVE FUN IN SCIENCE CLASS!!!
