Amy Truemper

Amy Truemper

Amy teaches 7th and 8th grade science at Bednarcik Junior High School in Aurora, IL. Along with chemistry, she also teaches physical science, life science, and engineering. Amy started her teaching career 22 years ago as a Peace Corps volunteer in Lesotho, Southern Africa. Without many materials and without access to the internet for ideas, she learned how to teach chemistry using creative methods that still resonate with students today. Her students participate in the Beauty and Charm program through Fermilab which has helped inspire students to pursue degrees in chemical and nuclear engineering. As an EarthEcho Fellow, she helped with the curriculum writing for Water by Design which connects chemistry with earth science topics. She is currently part of the American Nuclear Society K–12 Education Advisory Group. Bednarcik Junior High became one of the first middle schools to participate in the AACT ChemClub Program during the 2022–23 school year, and the club had a blast with the monthly themes. Outside of teaching middle school science, Amy enjoys traveling, nature photography, and learning more about sustainability. A highlight of her career was receiving the Fulbright DAST Award in 2022 and traveling to northern Vietnam to teach STEM lessons to students and teachers.
