Ohio 4‑H was proud to participate in the fourth annual We Grow Scientists event, part of the COSI Science Festival, held on April 29 at The Ohio State University’s Waterman Agricultural and Natural Resources Laboratory. This free, family‑friendly event invited participants to explore hands‑on activities highlighting science, technology, engineering, arts, and mathematics (STEAM) opportunities offered through the College of Food, Agricultural, and Environmental Sciences (CFAES).
In addition to showcasing CFAES academic and research areas, the event gave participants a behind‑the‑scenes look at the Controlled Environment Agriculture Research Complex (CEARC). Participants discovered how innovative agricultural research is shaping the future of food production and explored how controlled environments are used to grow crops sustainably. Interactive activities helped participants connect agricultural concepts to their everyday lives.
Ohio 4‑H hosted two engaging, hands‑on learning stations during the event. Inside the CEARC, participants explored the importance of cotton through a sensory‑based experience, using sight and touch to examine everyday products made with cotton, including currency, rope, and fabric bags. They then took part in a weaving activity that demonstrated how cotton fibers are turned into textiles. This part of the station also showcased how cotton fabric construction is affected by knitting versus weaving. Knitting cotton produces a stretchy, soft material, whereas weaving produces sturdy, tough fabrics. 
Carrie Davisson, Ohio 4-H Content and Editorial Strategy Specialist, shared, “As our 4-H team introduced concepts about the science and versatility of cotton to intergenerational learners, it was rewarding to see the hundreds of lightbulb moments! By completing learning activities, participants were eager to “earn” their tickets to receive a unique and memorable take-home item from the event. I especially enjoyed watching the youngest participants teaching the oldest ones how to weave. 4-H’s short, yet information-packed activities provided foundational understandings about STEM concepts each participant will find useful for a lifetime.”
At the conclusion of the station, participants were able to take home a cotton tote bag featuring Ohio 4‑H messaging. One side encouraged participants to “Grow with Ohio 4‑H,” while the other allowed them to express their creativity. They selected a cotton‑themed design that was heat‑pressed onto the bag, creating a personalized keepsake that reinforced the impact of cotton and Ohio 4‑H in their lives.
The Mobile Design Lab also made a stop at We Grow Scientists, offering participants a chance to explore technology and creativity. Activities included programming and racing Sphero Bots, creating music using GarageBand, and playing Pictionary on iPads. These experiences introduced participants to engineering concepts while encouraging imagination, collaboration, and creative expression.
Ohio 4‑H enjoyed connecting with the community and inspiring curiosity through innovative, hands‑on learning. The We Grow Scientists event provided a wonderful opportunity to celebrate discovery, creativity, and the many ways STEAM fields connect to agriculture and everyday life.
