Designing Experiments and Reading Graphs in Earth Science...
PARTS OF AN EXPERIMENT: 1. VARIABlES: THE PART OF AN EXPERIMENT THAT CHANGES GRAPHING: independant variable: the part of the experiment that you have control over dependant variable: the part of the experiment that responds to the independant variable changes
2. Constants: variables in an experiment that are kept the same in all trials 3. Control: the part of the experiment that is used for comparision
Graphing Data x-axis: independant variable y-axis: dependant variable
Types of Graphs Bar graph Line graph (most commonly used in ES) Cyclic graph
Relationship between Variables: Direct Relationship: both variables are increasing or decreasing Indirect Relationship: one variable increases and the other decreases Constant: stays at same value for a variable
Patterns on a graph: Linear: direct or indirect relationship Cyclic: repeats in a predictable manner
What Type of Relationship is Shown?
