This activity allows students to use real data obtained by them to model quadratic equations. Students will use the TI-83 and/or TI-84 and a motion detector to collect their data. The students will then manually fit both quadratic and linear equations to the data. They will then use quadratic regression and linear regression to check their equation and compare their results.
Before the Activity
Each student should have access to the TI-83 Family or TI-84 Family of calculators. Please see attached teacher outline for further instructions.
During the Activity
Provide each student with a copy of the attached .doc file.
After the Activity
Review student answers:
As a class, discuss questions that appeared to be more challenging
Re-teach concepts as necessary
