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
