Rain Game brings science learning to children in the hospital
Brian Jernigan, director of summer STEM programs for , is working to bring science learning to students who canāt come to class in person: young patients in pediatric hospitals.
That goal was on display May 17 in Mark Applingās class at Ryan Elementary School in Lafayette, Colorado. There, third-grader Jaejune Lee played with an unusual toy. A little bigger than an iPad, the game was designed by Jernigan and at CU Boulder for kids at Childrenās Hospital of Colorado in Aurora. Itās a Plinko-style toy that uses rolling beads and twisting dials to teach young learners about how water cycles from rivers to clouds and back again.Ģż

And it got Jaejuneās vote: āI thought it was pretty cool,ā he said, because of āhow we learned how the water cycle works.ā
Jaejune and his classmates arenāt patients themselves. But over the past year, pupils at Ryan Elementary worked with the CU Boulder group to help develop this toyābrainstorming ideas and product testing early versions. Jernigan came to class that morning to show the final result of that hard work.
He said that the project convinced him that engineering such resources can be empowering for kids both in and out of the hospital.Ģż
āThese kids are talking about their experiences. Theyāre getting it out in the open,ā Jernigan said. āYouāve heard of art therapy, and youāve heard of music therapy. Weāre looking at design therapy.ā
And itās been a success. In April, Jernigan delivered the first prototype of the toy, dubbed the āRain Game,ā to Childrenās Hospital at a ceremony that included an appearance by Miss Colorado. Heās also partnering with staff at the hospital to hold a workshop where patients can practice designing their own educational and therapeutic toys.
The need for such resources is huge, added Jernigan, who also volunteers at the hospital in his free time. āI see how bored these kids are,ā he said. āAnything you bring that is special or engaging is really going to lift their spirits and lift their parentsā spirits.ā
But thatās no easy feat. To keep kids safe, Childrenās Hospital follows strict rules for the toys patients can play with: no sharp edges, easy to disinfect, no bright colors or flashing lights that could trigger seizures. That makes designing even a simple educational toy an engineering challenge.
To meet that challenge, Jernigan tapped a group of students in the senior design course in the Department of Mechanical Engineering. He gave those students a unique charge: āI told them, āI want the kids to drive your excitement,āā he said. āI want you to spend time with them and really understand the client.ā

The work was supported, in part, by a CU Boulder Outreach Award with assistance from the universityās Idea Forge and Design Center Colorado.
The students jumped at the chance, paying several visits to Ryan Elementary and a preschool in Broomfield called Bal Swan Childrenās Center. And, Jernigan said, these young focus groups were full of good ideas. An early version of the toy, for example, used silver beads to represent water. One student at Bal Swan had a different idea: why not switch to blue beads?
These visits also showed Jernigan the therapeutic value of the design process. Many of the young students had friends or relatives who had been in the hospitalādesigning a toy helped them to work through their feelings on those struggles. Others were just happy that adults were listening to their ideas and taking them seriously.Ģż
Mark Appling, a science teacher at Ryan Elementary, said that his students enjoyed that responsibility. āIf you give kids a real problem and a real stake in problem solving,ā he said, āthey tend to do great things.ā
Itās those great things that drew CU Boulder student Rachel Sharpe to working with Jernigan. Sheās a junior studying mechanical engineering and two years ago, helped him to hold a science fair, complete with hands-on activities, in the main lobby of Childrenās Hospital.Ģż
Sharpe joined Jernigan in the visit to Ryan Elementary and spent the morning working with students in Applingās class, which encourages students to explore their own science and engineering projects. She helped a group of children to cut out figures for a custom board game and chatted with Jaejune Lee and another classmate as they built a cardboard train that transports puzzles.Ģż
When it comes to working with kids, āwhatās exciting is how creative they are,ā Sharpe said. āTheyāre fearless in how they solve problems.ā
