1. Earth Science Daily Challenge, 9/9 What is a MODEL? Give at least 4 different examples of models.

2. are representations of real objects, systems, or ideas. Scientific models can be classified into three categories… –Physical –Mathematical –Conceptual MODELS

3. can be touched, manipulated, etc. often “scaled” to the real thing usually used to explain or describe things, to help visualize Examples –human body plastic torso –model planes, cars, rockets –solar system model PHYSICAL MODELS

4. mathematical equations that describe the behavior of a system often used to predict what will happen if… also called “computer models” Examples –weather forecasting models –astronomy models MATHEMATICAL MODELS

5. organized ideas about how something works used to understand something Examples –how gravity works –blueprints for a building –Earth is made of layers – crust, mantle, core –how the solar system moves CONCEPTUAL MODELS

6. Real things might be too big, too small, too complicated, too far away, etc. to study directly! Scientific models can… –help explain how things work –help people visualize things –make predictions - what will happen? Models are limited… –only as good as the data that went into creating them, must be TESTED Why use MODELS?

7. Earth Science Daily Challenge, 9/10 Make a goal for your earth science grade this quarter. What grade do you plan to earn in this class? What will you need to do to make sure you reach this goal?

8. Earth Science Daily Challenge, 9/11 What do you already know about Hawaii?

9. Earth Science Daily Challenge, 9/14 List as many branches of science as you can think of in 2 minutes and briefly explain what each one is... For example, Physics - the study of matter and energy What are some others? HINT: (think of “–ologies”)
