Chapter 1 Study Guide (SCIENTIFIC METHOD)

● What are the steps in the scientific method? Make observations Formulate a hypothesis Devise testable predictions Conduct experiments/make additional observations Draw conclusions ● What kinds of observations are we talking about when we are talking about science? There is an infinite amount of observations. Ranging from physical appearance to patterns to cause and effect relationships of whatever you may be observing. For physical appearance this may include size, shape, color, smell, etc. Patterns may include breeding, migrational, and behavioral patterns. As for cause and effect relationships it’s pretty simple… something happens a certain way causing something else to happen. ● What types of explanations count as hypotheses? Ones that are not subjective and can be tested

● What is the goal of an experiment? The goal of an experiment is to determine if a certain hypothesis is correct and/or determine the effects that the treatments are having on the dependent variable.

● What is a control group, and why is it needed in an experiment? The standard that you can make comparisons with. It’s not altered. Do not apply any independent variables.

● What kinds of variables can affect the results of an experiment? What are ways to minimize the effects of those variables? Anything that may alter the experiment. Including location, temperature, the people working on the experiment, etc. Keeping certain aspects constant, diligently follow plan. ● What is the benefit of using the scientific method? ?Provides a layout/guidelines for an experiment so you aren’t going about it willy nilly. ● How is a scientific theory different than a hypothesis? Hypothesis vs. Theory. A hypothesis   is either a suggested explanation for an observable phenomenon, or a reasoned prediction of a possible causal correlation among multiple phenomena. In science  , a theory   is a tested, well-substantiated, unifying explanation for a set of verified, proven factors....
