About Geekbus

The GEEKBUS is a K-12 mobile makerspace that travels to schools to provide STEM programs. It is a high-tech shop class on wheels for the 21st Century. Our goal is to spark students’ interests in Science, Technology, Engineering and Math (STEM). Inside the Geekbus, you will find 3D printers, robotics, electronics and high definition screens for computer programming. With our programs, students will be given the opportunity to learn new skills by using tools and equipment that they would otherwise not have access to. With the explosive growth of STEM careers in San Antonio, we are also building the next generation of local STEM talent by catering to schools and other educational programs to reach underserved populations.

The Geekbus program is operated by SASTEMIC, a San Antonio nonprofit organization aimed at connecting education, business, industry and military to bolster the local STEM economy. Rackspace, Geekdom and the 80/20 Foundation are also strategic partners in support of the Geekbus.

Our Program

The goal of all Geekbus programs is to inspire and spark students’ interest in skills needed for the 21st Century. We teach students the value of “Design Thinking,” so that they can apply it to solve problems that not only exist in science and technology, but in their daily lives as well. By using Project Based Learning we also provide students with real world scenarios for learning. With the Geekbus education programs, students will learn new skills in Science, Technology, Engineering and Math (STEM). We offer programs from Kindergarten through High School and focus on 4 STEM pathways: Computer Programming, 3D Printing, Renewable Energy and Robotics
