SPACE SHUTTLE ASCENT: MASS VS. TIME

Algebra 1

Key Topic: Modeling data with linear regression equations

Students will be asked to create scatter plots and find linear regression equations using mission data on the mass of the space shuttle during the first two minutes of the ascent phase.

Students will
• create scatterplots from a data table;
• determine correlation and interpret its meaning;
• find linear regression equations;
• find the slope and y-intercept from a linear equation; and
• communicate the meanings of slope and y-intercept as they relate to a real-world problem.

Prerequisites: Students should have prior knowledge of scatter plots, types of correlations, linear equations (slope and y-intercept) and linear graphs. Students should also have experience using a graphing calculator or spreadsheet application to create scatter plots and to find linear regression equations.

Note: This problem is related to the Algebra 1 problem in this series, Space Shuttle Ascent: Altitude vs. Time.
