Activity Overview
Using data from the USA TODAY graphic, "Humidity makes air feel even hotter" students will explore quadratic and cubic functions to
determine how well they model the relationship between air temperature and heat index. When the models have been determined, students will use these models to make predictions about the heat index when given a specific temperature.
Before the Activity
Setup your TI-Navigator System
Make sure you are familiar with the following functions: Send to Class, Collect from Class, Screen Capture, Quick Poll and Activity Center
Your students will need a TI-83 Plus or TI-84 Plus graphing calculator, either working in pairs or individually
Download the attached activity resource files from all three sections to your computer
Recommendations:
Multimedia Projector for sharing the Activity Center, Quick Polls and Screen Captures with your students
TI Keyboards for students to easily answer the LearningCheck assessment questions
During the Activity
Students will:
Explore quadratic and cubic functions that will model
the relationship between air temperature and heat
index at fixed relative humidity values
Make generalizations and apply the findings
Directions
Distribute the Student Edition PDF file to your class
Follow the activity procedures outlined in the Teacher document
You may use the Graphic PDF file to display a large image of the USA TODAY graphic during the activity
After the Activity
Access your students' understanding by using Send to Class, LearningCheck™ App and Class Analysis.
