natural science

Many of the sub-disciplines often overlap with into

several branches.

Science vs. TechnologyScience is knowledge and methods

used to find that knowledge.

Technology is the applicationof the knowledge learned.

Big Ideas in Physical Science

● Space and Time● Matter and Change● Forces and Motion

● Energy

Scientific MethodA series of steps

used to solveproblems observed

or to betterunderstand theobserved event

Some examples of models

Scientific NotationA method of writing very large or very small

numbers in a way that is easier to use.EXAMPLE:300,000,000

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
