Hypothesis, Theory And Law Essay
2) Explain in detail the relationship between the concepts of a hypothesis, theory, and law. Be sure to not only define each word but to discuss the intricacies of how these three concepts are related. You should also include a discussion that explains why a scientist might get offended by someone who refuses to accept the validity of a scientific theory by claiming, “it’s just a theory,” and someone who claims that a hypothesis is an educated guess.
A hypothesis is based on prior knowledge and observations; it should be falsifiable. Hypotheses are used in experiments to predict the outcome explaining why, how, or what will happen in an experiment. In order for hypotheses to be deemed correct, they must be supported by the experiment. …show more content…
A theory can predict the outcomes and explain the data that is observed. A theory is never proven, but it can be revised. Theories are considered as true as a law, but just are not called laws. Theories may change until more is learned about it; it can be part of a hypothesis.
A law is the description of what happens. A law cannot be changed and has no exceptions to it. Laws are always true and are accepted universally. A law doesn’t describe why or how like a theory does. It is just telling what happens in nature or in an experiment. This information comes from previous experiments and …show more content…
They are all connected but are all different. People need to understand these differences because without understanding them, our society cannot understand the world of science as scientists began to make more and more discoveries.
9) Explain the process of osmosis using appropriate terminology associated with discussing differences in concentration. Based on what you should have learned about osmosis, discuss why the term “reverse osmosis” can be both an accurate and an inaccurate term when it is used to describe water filtration. Osmosis is the diffusion of water across a semipermeable membrane, or a membrane that only allows certain substances to pass, moving from high concentration to low concentration. Osmosis moves in only one direction. In organisms, a hypotonic solution has a lower concentration than than the cell so water moves into the cell causing the cell to burst. A hypertonic solution has a higher concentration than the cell so water moves out of the cell causing the cell to shrink. An isotonic solution is equal inside and outside the cell so water moves equally in and out of the cell and the size of the cell stays the same.
