Graphing Relationships
We learn about the scientific method and the different aspects of an experiment by using a potato launcher. We also discuss the various types of graphs explored in this course.

Learning Objectives
-Introduce the scientific method and discuss how data is gathered and displayed on a graph.
-Discuss the difference between independent and dependent variables and the importance of keeping other factors consistent so we have only one independent variable.
-Show how to clearly graph data from an experiment and what “red flags” to look for in skewed graphs.
-State the information that can be obtained from a graph and the equation of a best-fit line.
-Analyze different types of graphs that will be commonly seen in this physics course.

Vocabulary
extrapolation - estimating a value beyond a set of data points on a graph. hypothesis - an educated guess. independent variable - a variable that is directly changed in an experiment. dependent variable - a variable that changes in response to the changing independent variable. interpolation - estimating a value within a set of data points on a graph. scientific method - a methodical way to test a hypothesis, based on data collection and having controlled variables. |
