Students will explore data from worldclimate.com. They will write a sine function to fit the data. They will compare and contrast the characteristics of the graph and the data and find a relationship between climate and distance from the equator.
Before the Activity
Review the transformation model for the sine function with the students. Make sure they know how to navigate from page to page; from split page to split page and that they know how to enter data and adjust window setting.
Download the associated student TNS file and have it available to send to students.
During the Activity
Walk around the classroom. Make sure students are familiar with working with split screens.
After the Activity
Allow students to share their results by plugging their Nspire into the overhead panel.
