Physical Science

Quantitative Observation

Numerical measurements or observation.

Qualitative observation

things you notice or observe using senses

Evidence

facts or observations that support an idea

controlled experiment

experiment when only one variable is change

controlled varible

factors kept the same or constant for all experimental groups

control

group that provides a baseline to compare to other groups

experimental groups

recieve a different amount or type of the variable you are changing

independant varible

factor you change in an experiment

dependant variable

factor you measure in an experiment

direct relationship

a change in the independent variable causes the same change in the dependant variable

indirect relationship

change in the independent variable causes the opposite change in a dependent variable

exponential relationship

change in the independent variable causes the change in a dependant variable at a faster rate.
