Education at its finest – Steaming along with the STEAM Bus

Science, Technology, Engineering, Art, and Mathematics

What a fantastic project and one Victron Energy are proud Platinum Sponsors of, but what is the STEAM bus and project all about?

STEAM stands for Science, Technology, Engineering, Art, and Mathematics. The STEAM Bus is Van district’s latest learning resource for teachers and students in grades PreK-12. Van is a city located in Texas and Van ISD (Independent School District) consists of five school campuses that serve more than 2,200 students – all located in East Texas, close to Dallas.

The STEAM Bus is makerspace on wheels providing hands-on learning activities, across a variety of STEAM disciplines, where students can spend 45-60 minutes engaged in problem-based activities using technology such as tablets, Chromebooks, microscopes, ARVR equipment, robots, etc. The bus also hosts professional development opportunities, so teachers can have cutting edge resources and the skills needed to provide an enhanced educational experience for their students.

The beginning of STEAM

The STEAM Bus all started as a dream in the fall of 2017. The idea began when administrators started discussing how to get a makerspace on each Van ISD campus. A makerspace is a collaborative workspace inside a school for making, learning, exploring and sharing that uses high tech and no tech tools. The concept behind makerspace is more of a creative, problem-solving mindset and acquiring 21st-century skills in the fields of science, technology, engineering and math (STEM). For our makerspace, the team decided it was also important to incorporate an A for art; hence the name STEAM instead of STEM.

The problem they encountered during initial discussions was where to put these makerspaces since most campuses did not have the extra space needed to dedicate an entire room for that purpose. The solution? An old school bus that would be gutted, stripped down and transformed into a mobile learning lab and travel from campus to campus.

The old yellow bus before the age of STEAM!

Planning

The administrative team took the idea to Van High School iTeam students to get their thoughts and input. Kids said they wanted virtual reality, augmented reality, green screen capabilities, and coding opportunities. They then gave ideas on what the design and colour scheme should look like. A group of students and teachers even got to visit the Boy Scouts of America’s Mobile Makerspace in Austin, Keller ISD’s mobile trailer, and Winona ISD’s mobile reading lab to get even more ideas of what they liked and wanted to see incorporated.

Countless hours along with numerous challenges and problem-solving opportunities went into making the STEAM Bus a reality through months of in-house work by students, teachers, administrators, the technology and maintenance departments, along with a community volunteer.

The vision finally came to life as a 45-foot, one of a kind classroom on wheels that can travel from campus to campus, as well as outside the district to provide a unique learning experiences for pre-kindergarten through 12th grade students. The bus is equipped to hold 20 students inside and has additional teaching space on the outside for 10 more students.

The STEAM result

Here’s two videos of the final result, taken from the inside of the STEAM bus.

Going by the noise, the initial test run was a great success!

Conclusion

My, how steam has changed since I started as a Royal Navy Marine Engineering Artificer (steam), over 45 years ago. In my day they just removed the 4.5 gun from our RN training Frigate to act as an at sea classroom, with but tables, chairs, instructor and blackboard…

I think I prefer the modern STEAM way of learning!
