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. 

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 approaches (provided in the download section) for doing the project with students:

• "Project Materials" versions offer the most comprehensive approach, where teachers will find additional background on both coding and science concepts, and these materials also include a classroom presentation PowerPoint for teacher use. 
• "By Challenges" versions offer a shorter, streamlined approach to the project. Students are presented with a series of smaller tasks that eventually lead toward the final challenge. Check out both versions, and decide which approach is best for you and your class!
