A representation of an object or a system is called a model or prototype. ELO SPI 0807.T/E.1 What are the ideal tools and testing methods for testing a given prototype?

ELO Why do we need models or prototypes? Elbow Partners Discuss

Why do we need models or prototypes? Reality is complex and difficult. They allow scientists to work with systems that are too big or too small. They can be used to test ideas. ELO SPI 0807.T/E.1 What are the ideal tools and testing methods for testing a given prototype?

3 Types of Scientific Models Physical Models look like the thing they represent. For example, the model flower shown at right can be used to learn the parts of a real flower. 1.

2. Mathematical Models are made up of mathematical equations and data. The weather map shown below is a mathematical model. ELO SPI 0807.T/E.1 What are the ideal tools and testing methods for testing a given prototype?

3. Conceptual Models are systems of ideas or are based on making comparisons with familiar things to explain an idea. The big bang theory explains the origin of the universe. This theory is an example of a conceptual model. ELO SPI 0807.T/E.1 What are the ideal tools and testing methods for testing a given prototype?

Models Are Just the Right Size Models are often used to represent things that are very small or very large. For example, a cell in your body or the planet Earth would need a model for you to be able to study it. ELO SPI 0807.T/E.1 What are the ideal tools and testing methods for testing a given prototype?

Models are often used to help illustrate and explain scientific theories. In science, a theory is a unifying explanation for a broad range of hypotheses and observations that have been supported by testing.

Exit Ticket Section: Scientific Models To teach cardiopulmonary resuscitation (CPR), instructors often use a mannequin to model a human upper torso and head. Why do you think CPR is taught with a model instead of a real human? Would the class be as effective if a model were not used. Write your answers in your scientific Notebook
