SAN ANTONIO—As the popularity of STEM studies continue to grow, the Geekbus in San Antonio is bringing hands on learning to classrooms across South Texas focusing on science, technology, engineering, and math.

The Sastemic Geekbus is a 40 ft. tech shop on wheels and has been visiting students in schools since 2014.

Inside, it contains computers, 3D printers, robots, and other equipment designed to be explored. The hands-on format shows a practical element of science, technology, engineering, and math. There are six programs schools can choose from based on grade levels.

"I think since I learned how to do this I want to learn how to program some more and code and all that. I think it'll be pretty cool,” said student Cesar Zapata.

So far the Geekbus has visited more than 30 thousand students and their families.

"With open source technology we're able to teach students who wouldn't normally have access to these skills, how to use them now in fifth-grade or third-grade and start them now then they're proficient by the time they're out of high school,” said Tanja Hernandez, Sastemic program manager.

Sastemic plans to expand the Geekbus fleet by next year. Another bus will tour around Texas, while the third will travel across the country.
