- 1. Scientific Models<br />Introduction to Science<br />Chapter 3.3<br />
- 2. Objectives:<br />Explain how models are used to represent the natural world.<br />Identifythree types of scientific models.<br />Describe theories and laws.<br />Bellringer:<br />To teach cardiopulmonary resuscitation (CPR), instructors often use a mannequin to model a human upper torso and head.<br />Why do you think CPR is taught with a model instead of a real human?<br />Would the class be as effective if a model were not used?<br />
- 3. Types of Models<br />Model<br />A representation of an object or a system.<br />Physical Models<br />look like they thing they represent.<br />For example, the model flower shown at right can be used to learn the parts of a real flower.<br />
- 4. Mathematical Models <br />Made up of mathematical equations and data.<br />The weather map shown below is a mathematical model.<br />Conceptual Models <br />Systems of ideas or are based on making comparisons with familiar things to explain an idea.<br />Explains the origin of the universe<br />
- 5. Models are just the right size<br />Often used to represent things that are very small or very large.<br />Useful for studying cells and particles of matter that are too small to see with the unaided eye.<br />Also useful for studying objects that are too large to see completely<br />such as the Earth or the solar system.<br />
- 6. Models build scientific knowledge<br />Often used to help illustrate and explain scientific theories.<br />Theory<br />Unifying explanation for a broad range of hypotheses and observations that have been supported by testing.<br />Theories and models can change as new observations are made.<br />Charles Darwin’s Theory of Evolution<br />1897 Model of Atom<br />Current Model of Atom<br />
- 7. Scientific Laws <br />Formed when a theory and its models correctly predict the results of many different experiments.<br />Law is defined as:<br />A summary of many experimental results and observations.<br />Laws are not the same as theories. Laws tell you only what happens, not why it happens.<br />
