Seventh Grade Science at TFAA

Welcome to the 2025–2026 school year! My name is Mr. Shelton, and I’m thrilled to be your 7th grade science teacher at Thurman Francis Arts Academy. I can’t wait to begin this journey with you—it’s truly an honor to be part of your educational experience.
A little about me: I’m married, a proud parent of three, and I love spending time outdoors. I’ve been in education for 26 years, serving as a classroom teacher, science program coordinator with Vanderbilt University, and assistant principal. Most recently, I spent five wonderful years teaching 7th grade science at Stewarts Creek Middle School.
My core belief is that open communication, trust, and mutual respect between students, parents, and teachers are essential for success. Please don’t hesitate to reach out with any questions or concerns—I’m always happy to connect and will respond as promptly as possible.
In my classroom, I emphasize positivity and motivation. I believe students thrive when they feel encouraged and valued. To that end, I use daily and weekly incentives like Jolly Ranchers for everyday achievements, popsicles for winning classroom games, and ice cream to celebrate consistent hard work and perseverance. These small rewards build excitement and encourage students to give their best effort.
I’m passionate about science and teaching, and I’m committed to making this year both fun and challenging. You can expect to be engaged in hands-on science practices, encouraged to think critically about the world around you, and inspired to look forward to class each day. I believe in making the most of every moment we have together—after all, there’s no substitute for time on task!
One phrase you’ll hear often in my class is: “If you know the song, you know the science!” Get ready to learn through music, collaborate with classmates, move around, explore strange phenomena, ask deep questions, build models, and dive into all that the 7th grade science curriculum has to offer.
Let’s go, Rams!
Sincerely,
Mr. Shelton
