Theories in Science

Often people think of science as experimenting with test tubes, mechanical objects, and boiling different chemicals. Even though this may very well be true, science consists more of theories, hypotheses, and the search for answers. Science can be described as studying the phenomenon of the universe, observing, and taking data. Even discovering theories of experimentation before and after. The history of science should follow the many different methods of science. The scientific method of procedures that consists of measurement, formulation, systematic observation modification, and testing of different hypothesis. This paper will review the role of theories and the scientific method and demonstrate their importance through real life example and the relation to topics covered in Chapter 1 of Essential Biology with Physiology (Campbell, Reece, & Simon, 2007).

Theories and the Scientific Method

Most of the phenomenon recognized in nature can be explained by theories that scientists have developed through tremendous observation, testing, and the repetition of experiments. For example, photosynthesis and related processes, are a metabolic pathway that converts light energy into chemical energy occurring in plants (Marcus, 1997). The Marcus theory of electron aids in explaining the process of photosynthesis. Marcus successfully developed his theory to explain how element transfers energy by conducting a series of experiments on ‘isotopic exchange reactions’ and ‘cross reactions’ (Marcus, 1997) His experiments couldn’t have done without other scientific findings such as the Arrhenius equation for temperature and rate coefficient and Gibbs free energy, and those theories are well supported by other scientific findings (Marcus, 1997) In this way, a scientific theory is developed by testing and experimentation, and supported by other scientific theories developed through...
