What is a Theory

Watch the short video clip on YOUTUBE WHATIS A SCIENTIFIC THEORY? And how does that differ from a LAW* Now we know that a scientific theory is the culmination of many scientific investigations drawing together all the current evidence concerning a substantial range of phenomena. A scientific theory represents the most powerful explanation scientists have to offer. We will tie it to the theory of evolution by natural selection. Explain why the use of the term “theory” in science is different from the use of the word “theory” in everyday language. Because a scientific theory is used for scientist experiment How does a theory develop? A problem and a topic To become a theory, a hypothesis must be tested many times and it must be supported by a large amount of evidence. Why is evidence such an important part of this process? Why are some theories more widely accepted than others such as the theory of evolution? Forging out what he would expect to observe if an idea were correct and comparing that expectation to what we actually observe Because they get supported by wasn’t body of evidence and are testable and falsifiable Using the Concepts of “ WHAT A model that guides inductive inference by determine which of competing hypothebse beest explain evidence HAPPENS” vs “HOW IT HAPPENS”, state the best explanation of a scientific theory Read the following passage to help answer the questions below: The theory of evolution by natural selection is a scientific theory. Evolution is a change in the characteristics of living things over time. Evolution occurs by a process called natural selection. In natural selection, some living things produce more offspring than others, so they pass more genes to the next generation than others do. Over many generations, this can lead to major changes in the characteristics of living things. The theory of evolution by natural selection explains how living things are changing today and how modern living things have descended from ancient life forms that no longer exist on Earth. No evidence has been identified that proves this theory is incorrect. The theory of evolution by natural selection is the process by which organisms change over time as a result of changes in heritable (genetic) physical or behavioral traits. Changes that allow an organism to better adapt to its environment will help it survive and reproduce to have more offspring . How the offsprings adapts to its trails When Charles Darwin first proposed the idea that all new species descend from an ancestor, he performed an exhaustive amount of research to provide as much evidence as possible. Why was this so important to the development of his theory? To make theory from a thought of test Evolution by natural selection is one of the best substantiated theories in the history of science, supported by evidence from a wide variety of scientific disciplines, including paleontology, geology, genetics and developmental biology. The repeat of testing new evidence Could the theory of evolution change? If so, what type of evidence would be needed to support that change? Evidence from paootgy geology
