Dallas — What surface will provide the best mobility for a person in a wheelchair…and why? That was the question posed to 89 George West Middle School students recently as part of their science lesson. Thanks to engineering curriculum from SMU Lyle School of Engineering’s The Infinity Project, students integrate science and math lessons using hands-on projects where they work collaboratively in groups, like real engineers.

Under the direction of Caroline Meyer and Phillip Devanney, eighth grade math and science teachers, students tackled a wheelchair ramp project. They ran model cars down a ramp divided into three sections: grooved rubber, bare wood, and painted wood. After timing how fast the cars traveled, the teams concluded which would be the safest choice for a wheelchair ramp as the surface with the most friction. The conclusion: Although the students reported varying results, a matte-finish rubber or roughed-up rubber should prevent slipping and provide a slow, safe descent.

“This problem-solution approach really appeals to an inquisitive young mind,” says Linda Clark, Technology Applications instructor at George West Junior High. “The wheelchair ramp project went really well and our math instructor plans to revisit the lesson later in the year, taking students to areas around the school to measure actual ramps on campus and the football field.”

The affordable Infinity Project program delivers teachers rigorous, yet flexible lesson plans that incorporate more than 350 engineering and technology hands-on projects to make learning both fun and relevant. For example, as part of one Introduction to Engineering lesson, seventh grade students conducted the egg bungee drop experiment. In Simple Machines, students designed a catapult. During the spring semester, teachers plan to introduce Rocketry, Robotics, and Digital Imagining.

The Infinity Project was developed 10 years ago by SMU Lyle School of Engineering, Texas Instruments, National Instruments, the U.S. Department of Education, the National Science Foundation, and others to help students see the real value of science and math and encourage this generation to pursue a career in engineering. To date, The Infinity Project has impacted over 5,000 students in 38 states.

Tammy Richards, Associate Dean of SMU’s Lyle School of Engineering and Director of The Infinity Project, advocated adding engineering as a fourth year science in Texas. Texas school districts can now offer plug-and-play engineering curriculum to college-bound students, laying the foundation for a successful transition into college-level engineering courses.

The ultimate goal, of course, is to increase the number of middle school and high school students who later pursue careers in engineering and technology. More than half of the U.S. economy’s growth in the last 50 years is due to scientific and technological innovation. Despite this, the statistics are sobering:

Less than 15 percent of U.S. high school graduates have the background to major in engineering.

“From engineering the ultimate karaoke machine to designing a digital backpack, or performing an autopsy of a VCR, The Infinity Project delivers hands-on experiences that instructors can use to encourage students to problem-solve and work collaboratively, today in the classroom and tomorrow in the workforce,” says Richards.
