Do STEM Projects with students after exams or summer STEM camps

Texas Instruments (TI) STEM Projects are great for keeping students engaged in learning real-world skills after exams are complete or during summer STEM camps. These motivating, engaging activities encourage collaborative problem-solving, lively discussion, exploration and discovery of connections in science, math, engineering design and robotics.

We help remove barriers to student achievement


Get started with lesson ideas

Below you’ll find free, project-based activities set in real-world contexts perfect for middle grade and high school classrooms, after-school clubs and special STEM events.

Never coded before? No problem! Our 10 Minutes of Code lessons provide a foundation in creating, running and editing TI-Basic and Python programs with the
TI-Innovator™ Hub with TI LaunchPad™ Board and the TI-Innovator™ Rover.

Need equipment?

With our loan assistance program, we can lend you the materials and technology needed for your project(s), including a TI-Innovator™ Hub and TI-Innovator™ Rover.

The equipment list will show you what you’ll need for each of the STEM Projects activities mentioned below. This will aid you in your budget requests and grant proposals.


We're here for you

The TI STEM team is ready with ideas, tips and assistance to get your project under way. Plus, TI STEM experts and the
TI-Cares™ teacher support team are always on hand to help you get back on track if you get stuck.

Projects that use the TI-Innovator Hub

TI-Innovator Hub

Students sharpen their critical and creative thinking skills as they define problems and design and refine solutions using a TI-84 Plus CE or TI-Nspire™ CX graphing calculator to program a TI-Innovator™ Hub.


Digital Mood Ring

This activity is “square one” for using TI graphing calculators to code the TI-Innovator™ Hub on other STEM Projects. Students program input and output feedback controls to make the built-in lights on the TI-Innovator™ Hub mimic the colors of a mood ring.

Pet Car Alarm

Engage students in the math and science of the greenhouse effect by designing and building a pet-smart alarm system that sounds an alert when the interior temperature of a model car approaches the danger zone.

STEM project Array

Running the Bases (with TI-RGB Array)

The TI-RGB Array provides another level of engagement as students experiment with controlling each of the 16 individual RGB LEDs. Math, science and design all come together when using the TI-RGB Array.

Projects that use the TI-Innovator Rover

TI-Innovator Rover

When the wheels are turning, students are learning. The TI-Innovator™ Rover — controlled by a Hub that is programmed with TI graphing calculators — puts math and science in motion.

Rover, Rover - A Dog looking over the TI-Innovator™ Rover robotic vehicle

Rover, Watch Out for Rover!

Challenge students to experiment with distance, time and speed in an effort to make the TI-Innovator™ Rover robotic vehicle stop just short of a plastic dog (the other “Rover”) placed at a random distance by the teacher.

On-Ramp to Robotics


Unit 1: The Mars Rover Challenge

This (motion) activity introduces students to the coding and hardware-control practices and processes NASA engineers use to keep a remotely operated vehicle on track while exploring another planet.

Math in Motion

Help your classroom experience math in a whole new way with activities that put math in motion. Students can code their own programs to control Rover, or they can explore math concepts using premade programs.
