It is read-only. Select All A model. What can scientists build to test their hypothesis? A pattern, plan, representation, or description designed to show the structure or workings of an object, system, or concept. What is a model? To represent objects or systems. What do scientists use models for? Something familiar. What does a model use to help us understand something? Physical, Mathematical, and Conceptual. List the three common types of scientific models. Physical Model. What type of model can be helpful to show things that are too small to see or how something works? Mathematical equations and data. A mathematical model is made of? Variables. Complex mathematical models can have many _______ fail. Omitting a variable in a complex mathematical can cause the model to_____.. conceptual model. What kinds of models are based on systems of ideas or comparisons with familiar things? By comparing them to help illustrate or explain an idea. How does a conceptual model make use of familiar things? mathematical model. A model used to predict the weather. conceptual model. the big bang theory, which describes how the planets and galaxies were formed. physical model. a model of a molecule. small, large, A model can help you see things in your mind that are very ______ and very ____. picture things that are very difficult to see. A coiled spring toy used to show how sound waves behave is an example of how models can be used to ________________. An explanation for many hypotheses and observations. What is a theory? Observations and hypotheses. What are theories based on? Explains observations you've made and helps you predict what will happen in other tests, What does a theory do? By using them to make new observations, which may result in the change of their theory. Explain how scientists use models to test theories. a law. What is a summary of many experimental results and observations called? Observations. A scientific law is formed only after many experimental results and ______. A theory explains why something happens and can be proven incorrect, while a law explains what happens and cannot be proven incorrect. How do theories and laws differ? Law of Conservation of Mass. What laws says that the total mass of materials formed is the same as the total mass of the starting materials?
