This investigation will help you to:

1. Learn that evidence consists of observations and data on which to base scientific explanations.
2. Understand that a model is a type of scientific explanation that uses existing knowledge and new evidence from observations.
3. Understand that models correspond to real objects, events, or processes, and that have explanatory power.
4. Be able to give examples of different forms of models, including physical objects, conceptual models, mathematical equations, and computer simulations.
5. Learn that models are tentative; they are subject to revision in light of new evidence.
