Middle & Upper School Science Teacher

We are seeking a Middle School Science Teacher who centers young adolescents while designing learning that is rigorous, experiential, and deeply human. Reporting to the Head of Middle \& Upper School, this role calls for a teacher who can facilitate innovative life and physical sciences learning. A strong candidate should be comfortable facilitating heterogeneous classrooms, guiding skills-based and experiential labs, and designing interdisciplinary projects that connect quantitative reasoning with real-world inquiry.

A Barrie, our teachers serve as learning guides; at a most fundamental level, they have

A Different Vision of Rigor: At Barrie, rigor isn’t just about mastering difficult or test-centered content—it’s about learning to ask rich questions that fuel wonder, stretch thinking, deepen understanding, and inspire students to do something with what they’ve learned. We believe that to be truly rigorous, the work that learners do must allow them to engage with complexity, play with possibilities, take intellectual and creative risks, and turn critical thought into thoughtful action. Students should not simply study issues—they should build toward solutions, create work that matters, and take steps toward change in ways that feel personally meaningful and globally relevant.

The Spirit of a Mentor: Guides understand that students can shape their own learning pathways—balancing deep experience in areas of interest with wide perspectives across others. Guides build in time to think, reflect, make goals, and grow self-awareness. Students learn their strengths, practice advocating for themselves and others, and build the confidence to adapt when things don’t go as planned. Guides frame even missteps as successes that foster learning and growth.

The Heart of a Generalist: While they will teach subject-specific courses, guides are energized by learning and teaching across disciplines, helping students make sense of the world as a connected whole rather than a collection of separate subjects. They design hands-on, collaborative, real-world learning experiences that spark insight by crossing boundaries—where science connects to story, math meets making, art informs solutions, and big questions lead to meaningful ideas.

The Desire to be a Mixed-Grade, Mixed-Level, Interdisciplinary Facilitator: Guides are especially at home working with mixed-grade, mixed-level cohorts in which students learn with and from one another. They intentionally structure learning environments so collaboration builds smart thinking, growth, empathy, and strong community.
