Inputobserving: using one or more senses to

gather information.inferring: explain your observations.predicting: making a forecast of what will

happen in the future based on evidence.chemistry: study of the properties of matter

and how matter changes.physics: study of matter, energy, motion, and

forces, and how they interact.

measurements; quantitative, measurements

ModelingWhat are inferences based on?

reasoning from what you already knowWhat are the two main areas that

physical science is divided into?chemistry and physics
