4 – Design a model that explains a science concept.
3 – Identify the benefits and limitations of scientific models.
2 – Identify the benefits OR limitations of scientific models.
1 – Identify examples of scientific models.

3. What is a scientific model?
Scientists use drawings, graphs, equations, 3-D structures, or words to communicate their ideas (models) to others.

4. Why is scientific modeling important?
May be too small to be seen (an atom)
Inaccessible for direct visual study (the center of the Earth)
Can only be studied by its affect on matter (gravity)

5. New scientific discoveries and understanding frequently depend on scientists developing scientific models and interacting with them.

6. Do Models Ever Change?
Models change as new evidence or information is discovered.

7. Benefits & Limitations of Models
Easier to use
Safer to use
Saves money
Helps you picture things in your mind
Limitations
Cannot include all the details
Models do not behave exactly like the things they represent
