  1. Model: A representation of an object or system. Using Models in Science

  2. Uses for models: • to describe or explain certain • characteristics of things • for making predictions • - for explaining observations

  3. Examples of models: • model rocket • model of matter, molecules, or atoms • model of a cell • - model of a building

  4. Models Help You Visualize Information • - Objects as models • - similar characteristics • - Ideas as models • - use an idea to create a model • – use your imagination

  5. Models Are Just the Right Size • - smaller model to represent a large thing • - model of solar system • - larger model to represent a small thing • - model of an atom

  6. Models Help Build Scientific Knowledge • testing hypotheses • - illustrating ideas

  7. Models Can Save Time & Money • small models cost less, take less time to build • small models can be destroyed in • testing

  8. REVIEW 1. Purpose of a model:

  9. 1. Purpose of a model: • to represent concepts or characteristics of objects that are difficult to see or hard to explain • to be used as a tool for testing & illustrating theories

  10. 2. Everyday examples of models:

  11. 2. Everyday examples of models: • - model car • - globe/map • - picture • - statue/figurine

  12. 3. When to use a globe:

  13. 3. When to use a globe: - compare sizes of different countries

  14. When to use a map:

  15. When to use a map: when traveling
