Segment G: 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.

-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.

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.

The Physics in Motion teacher toolkit provides instructions and answer keys for study questions, practice problems, labs for all seven units of study. GPB offers the teacher toolkit at no cost to Georgia educators.To order your teacher toolkit, complete and submit this form to request the teacher toolkit. You only need to submit this form one time to get materials for all seven units.
