Building Bridges: Graduate Students Mentor High Schoolers to Teach STEM to Young Learners
May 16, 2025

In a collaboration with both high school and kindergarten teachers in Radford, Virginia Tech graduate students Esther Oyedele and Padmaja Mandadi piloted a program this spring that allowed high school students to gain firsthand experience in science teaching.
Oyedele, an American Geophysical Union (AGU) Voices for Science Fellow and Ph.D. student in Virginia Tech's Department of Geosciences, had developed a lesson plan for kindergarten children that she delivered last year through the Center for Communicating Science's kindergarten science visits program at Eastern Elementary/Middle School. When Jamie Little, the public school/Virginia Tech liaison for Radford schools, asked CCS associate director Carrie Kroehler whether the program could be expanded to Radford schools, Oyedele was ready to step up.
Mandadi, a Ph.D. student in biomedical and veterinary sciences and a 2024-2025 graduate assistant for the Center for Communicating Science, organizes the kindergarten science visits at Eastern and lent her expertise to the Radford pilot expansion project.
Oyedele’s research focuses on identifying water levels in semi-arid regions of the U.S. using satellite data. For kindergarten children, she created a poster illustrating the water cycle and led an activity in which kindergarteners pinned water droplets onto the poster — an experience that left a lasting impression.
Motivated by the positive interaction with young learners and supported by her fellowship, Oyedele collaborated with Little, who helped form a team that included Beverly Edwards from Radford High School and Blenna Patterson from McHarg Elementary School. They aimed not just to share science with kindergarteners but also to prepare high school students to teach science to young learners in fun and suitable ways for their age and level.
Oyedele, along with Mandadi and Erin Smith from the Center for Communicating Science, held an online session with five high school students who are a part of the “Teachers for Tomorrow” program. They then visited Radford High School to work with the students in person.
Oyedele began by introducing herself to the high school students with the powerful statements: “I am a scientist” and “I am a girl,” reinforcing the importance of representation and encouragement for girls in STEM fields (science, technology, engineering, and mathematics). She described how she had adapted her complex research for kindergarteners using visual aids and interactive activities. Oyedele also coached the students on how to manage curiosity-driven interruptions from children and how to redirect the conversation while keeping the focus on the topic. She demonstrated activities such as coloring sheets and asked students to reflect on their favorite parts of a lesson and explain why they enjoyed it.

A week later, the entire team visited McHarg Elementary School, where the five high school students taught in six classrooms, each with approximately twenty young learners.
Oyedele led the first session to model the lesson, after which the high schoolers took the lead. They adapted and enhanced the content creatively — boiling water on a portable stove to demonstrate evaporation, using frozen water bottles to show condensation, and even composing a song with gestures to teach vocabulary in a fun and memorable way.

The high school students described the experience as thrilling and nerve-wracking at first but ultimately empowering. They expressed a sense of accomplishment in being able to connect with young children and make science understandable and exciting. Oyedele later shared that she found it both meaningful and joyful to introduce children to the kind of work she does every day.
Oyedele especially wants to thank Carrie Kroehler for her encouragement every step of the way, as well as Beverly Edwards and Blenna Patterson for helping make this happen. She also wants to thank the high schoolers — Laekyn Arnold, Skylar Hinkley, McKenzie Leighton, Haley Linkous, and Samara Woolwine — who showed courage and active participation.

The Virginia Tech/Radford schools liaison was pleased with the outcome of the project. “I just want to say how WONDERFUL the lesson was that you all presented to the kindergarteners!” said Little in an email. “Thank you, Padmaja and Esther, for sharing your expertise with our future teachers as well as with our littles. I think it was a win-win for everyone!”
