As we pedaled east, we taught hands-on lessons at middle schools and summer programs using the Sol Cycle, a miniature, 3D-printable, solar-powered bicycle that we have designed. We also profiled science educators about innovation in the classroom and curating science lesson plans, and are in the process of creating a repository of accessible, engaging activities for parents, kids and teachers alike.

We met while studying physics at UCLA. But neither of us entered school thinking we'd be scientists. Rachel arrived, trombone strapped to her back, set on a career in music. Elizabeth signed up to study English, hoping to side gig at the student newspaper. Curious about physics, we both enrolled in the same one-unit seminar on "The Arrow of Time" as freshmen.

A couple years and one backpacking trip to the Alps later, we found ourselves burning the midnight oil together in a particle physics lab and brainstorming between experiments about how we'd bicycle across the country. Now, we're both headed toward careers in science: Elizabeth is a PhD student studying glaciology at Columbia University, and Rachel is working towards a PhD in applied physics and solar energy at UC Berkeley and the National Renewable Energy Laboratory.

On our trip, our goal was to show the students we met that scientists aren’t all old white guys with calculators growing out of their beards, who spend 24/7 in underground labs and have been tinkering with circuits since preschool. We hoped to demonstrate how creative science can be and how much it already impacts their day-to-day lives.

Seriously though, diversity and engagement are two of the most pressing issues in science education. We don’t think we can solve these problems (at least not yet!), but this trip has sparked many conversations, and we hope it has inspired a few kids to become scientists and created lasting resources for educators to use in their classrooms.

From February to March 2015 we ran a crowdfunding campaign on Indiegogo to raise money for Sol Cycle prototyping, 3d printing and other educational costs associated with the trip. We reached and passed our goal! Here's the video from the campaign:
