DIY Mood Ring with TI-Innovator™

Updated on 03/18/2019

Activity Overview

In this TI-Innovator™ STEM project, students are given the challenge to design and build a digital mood ring using a pipe cleaner and a temperature sensor. This project is compatible with the TI-Nspire CX or TI-84 Plus CE handhelds. 

About the Lesson

Students will bring science and coding together as they create their own mood ring! In this STEM project using the TI-Innovator™ Hub, students will learn basic coding skills, explore color mixing, and experiment with body temperature ranges as they work to write a program that will display a mood, based on the changing temperature of their finger. Note there are two alternative methods of the projects available for download- the "Challenge" versions provide a streamlined approach to the project presenting a series of smaller tasks leading to the culminating challenge. The other project approach is more comprehensive "Classic" approach, offering additional background info as appropriate for the teacher, and also a classroom presentation PowerPoint for teacher use. 

Note: This project is an introductory level project appropriate for middle and high school students. It is considered the entry point for the “STEM Projects using TI-Innovator™ Technology”. It is strongly suggested that if your students do not have much familiarity with coding on the TI calculator, they start with this project to build skills and confidence, and then progress to more complex projects like the Pet Car Alarm, or Smart Water. Students will work through several 10 Minutes of Code lessons in this project.
