Interactive transformation graphing by grabbing or using sliders and data capture. 2 TI-Nspire CAS and TI-Nspire CX CAS Handheld Operating System Version 3. This version of the Release Notes has updates for all of the following products: TI-Nspire and TI-Nspire CX Handheld Operating System Version 3. Inequalities, 3D and Differential Equation (slope fields). Thank you for updating your TI-Nspire products to Version 3.2. You can reach out to the STEM Team for help. TI-Nspire CX CAS helps students explore, check their work, and do more mathematics the way that it appears in the textbook. For every project, there are teacher documents, student documents, completed programs, supplemental reference sheets on the programming language, and even videos to demonstrate the project. Texas Instruments’ STEM Projects give you a place to start with so many resources available to help educators with any level of experience integrating STEM activities into their classroom.

The students researched the different types and causes of arrhythmia, put together a presentation, and modified their code to model how the heartbeat would change. Now that they were familiar with writing the code and setting up the heart to show both the flow of blood (LEDs) and calculating the heart rate, I wanted them to do some research on arrhythmias or when the heart does not beat as expected. A Grove temperature sensor is used to modify the input, and students will need to write a program to increase the heart rate as temperature increases.Īfter using this activity with my AP ® Biology students, I had an idea to extend it and developed an end-of-year project for my AP ® students. Students will need to write a program to show how the heart rate changes based on different external input.
This challenge models the autonomic nervous system.

They can also figure out how to speed up or slow down their cycles and to calculate heart rate.Ĭhallenge 3 is where students must put their skills to the test. Students add in sounds after each cycle to beep like an EKG machine. To help the students that may be new to programming, comments are embedded in the Python editor page to provide support.Ĭhallenge 2 brings in modeling of the flow of blood through the heart by writing a program to blink four LED lights in a sequence to show the flow of blood through the heart starting with the right atrium and ending with the left ventricle. They also need to write a program to get the LED to blink at a certain rate. In challenge 1, students set up a simple circuit using the breadboard on the TI-Innovator™ Hub and a red LED. In “ The Plumber: Modeling the Four-Chambered Heart for the TI-Nspire™ CX II Graphing Calculator” activity, students need to complete three different challenges to demonstrate the function of a heart. The activities available at set up students for success by completing building skills with different challenges to help them become familiar with programming.

These activities are available using multiple platforms and languages: TI-Basic (TI-Nspire™ CX, TI-Nspire™ CX II or TI-84 Plus CE graphing calculators) and Python (TI-Nspire™ CX II and TI-84 Plus CE Python edition graphing calculators). Students become familiar with coding by using the easily accessible menu-based system within TI calculators. “The Heart Project” is a favorite of mine to go more in depth about the circulatory system, transport and homeostasis, but it also allows students to build electrical circuits and write a simple program to control the model. However, when the AP ® exams are over, I utilize as many of the STEM projects as possible. And just in time for Valentine’s Day and American Heart Month!Īs an Advanced Placement biology teacher, I don’t always have the time to do as much STEM integration as I like. “The Heart Project” is a great way to introduce your students to coding while teaching your students about the structure of the heart and flow of blood through the heart. Does your heart skip a beat when you think about STEM? If it doesn’t already, it will after you learn about the heart STEM project.
