Some examples of models

Scientific NotationA method of writing very large or very small

in scientific notation is written3.0 X 108

SI Units:A revised

version of the metric system that allows a

uniform set of measurements

to be use by scientists.

Graphing● Data Tables: simplest way to organize data● Line Graphs: useful for showing changes

that occur in related variables or how one variable changes over time

● Bar Graphs: used to compare a set of measurements, amounts, or changes

● Circle Graphs: show relationship between the parts to the whole
