Activity Overview
Students will explore linear & quadratic functions to determine how they model the relationship between air temperature & heat index. Once the models are determined, students will make predictions about the heat index when given a certain temperature.
Before the Activity
See the attached Teacher Edition PDF file for notes and guidelines for this activity. The Technology Guide PDF file includes step-by-step calculator instructions with screen shots.
During the Activity
Students will:
Model real-world data with linear and quadratic functions.
Create scatterplots using real-world data.
Compare data in graphical and numerical form.
Analyze rate of change.
Use piecewise functions to connect models.
Understand patterns, relations, and functions.
Directions:
Distribute the Student Edition PDF file to your class.
Follow the activity procedures outlined in the student document.
