Observation+vs.+Inference,+Scientific+Method

= Observations vs. Inferences! = = =

During class we generated a good word list to use for observations . Most, but not all are listed here:

 * 1) color
 * 2) shape (like square, circle, etc. . . )
 * 3) 3D or 2D

 * 9) texture
 * 10) magnetic or not magnetic
 * 11) living things are called organisms
 * 12) if there are numbers or words on the object. . . state them!

= Experimenting: = === In a controlled experiment, only one condition is changed at a time. The condition in an experiment that is tested is the __ independent variable __, because it is the only factor that affects the outcome of the experiment. === === While testing the independent variable, the scientist observes or measures a second condition that results from the change. This variable DEPENDS on the independent variable. This is called the __ dependent variable __. ===

= Graphing: =

===This graph is an example on how to graph the independent and dependent variable. The __X axis__ is ALWAYS the independent and the __Y axis__ is ALWAYS the dependent variable. This graph shows how your education level (independent) efffects your salary (dependent) as an adult!===
