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.

Unit 1 Segment G: Graphing Relationships We learn about the scientific method and the different aspects of an experiment by using a potato launcher. Examples of the various types of graphs that will be seen in this course are also discussed.

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.
