  1. Section 4 Scientific Models and Knowledge Chapter 1

  2. scale Scale is the relationship between the measurement of a model and the actual measurement of a real object Scale:1/10

  3. theory An explanation that ties together many related facts, observations, and tested hypothesis. Theories are used to predict what might happen in the future. Cell Theory ALTCC CBUSFALT ACPOC

  4. law A descriptive statement or equation that reliably predicts events under certain situations. Gravity

  5. Summary • A model is a representation of an object or system. Models often use familiar things to represent unfamiliar things. The three main types of models are physical, mathematical, and conceptual models. • Scale models maps, or diagrams match the proportions of the objects they represent. • Scientific knowledge is built as scientists form and revise scientific hypothesis, models, theories, and laws.
