A very common thread running through all of science is observation. Without observation, the laws of science could not be tested and examined. For example, if we have a law that states, “The temperature of the earth is always exactly twenty-five degrees Celsius,” how can we test and verify this? Without empirical observations we are simply spinning our wheels in an effort to prove something which simply is not possible. This is true for everything in science, including genetics and macroscopic phenomena. There are many examples of how science has been successfully used to study these diverse domains of study.
For example, in chemistry a project has to be executed in order to prove a hypothesis. There must be an observation of some kind in order for that hypothesis to be proven. This is how science progresses; observations are then gathered, analyzed and compared. If those comparisons show that there is indeed a relationship between a variable and its surroundings, then the hypothesis is proven. If there is no relationship at all then it is deemed to be an assumption, but again rigorous examination is needed. In order for us to apply this same process of basic science to the world around us we first have to examine all of our observations.
One such field of study is molecular biology. Here scientists are required to examine, manipulate, and observe cells. Cells are extremely complex both in structure and in function, and understanding them is a crucial part of the medical community. Molecular biology is a very interesting field of science due to the fact that we rarely get to witness the development of each and every cell in a living organism until the early stages of development.
Another area in science that is often not considered to be as cut-and-dry is physics. Physics deals with forces and objects and their interaction. A scientist can study nearly any aspect of this interaction, which makes it very interesting to study in addition to being incredibly complex in its workings. The complexity of Physics is often used to study the relationship between various theories.
Biology is an incredibly important part of science as well. We are constantly faced with the prospect of disease, infertility and birth defects, among other things. A scientist spends a great deal of time studying these problems and attempting to find solutions. Biologists often examine tissue samples under a microscope in order to look for signs of disease or abnormalities in cells.
Astrophysicists undertake projects to study stars and the universe. Astronomy is one of the oldest sciences and has had a profound impact on our society due to the telescope that we use to view the stars. A scientist can take an astronomy project and examine it at a scientific museum or research institution. They will take a telescope and use it to take a variety of pictures and videos in order to learn more about the universe and the way that our solar system works.
Science projects and science fairs can be a lot of fun if you take it seriously. You can examine a science project however difficult it may be and still come away with a very rewarding project. You can take an easy project and make it much more difficult, and that is just what happens in science. Good luck on your science projects!
