Mariah E.
Instructional Designer | K-12 Science Lessons & Assessments
I create K-12 science curriculum and learning materials for classrooms, digital learning platforms, edtech companies, publishers, and education organizations. I specialize in biology and life science, but can also support a range of K-12 science content needs, including: • Standards-aligned lessons and learning modules • Biology and life science curriculum writing • Hands-on and inquiry-based activities • Student-facing science articles • Practice exercises and assessment items • Teacher guides and implementation supports • Curriculum review, revision, and content editing I’m comfortable taking a project from an early idea or rough outline to a polished learning resource. I use digital tools, including AI, to support brainstorming, outlining, revision, and clarity checks, while relying on my science expertise and classroom experience to ensure final materials are accurate, age-appropriate, and instructionally sound. My recent experience as a Biology Content Creator focused on developing middle school biology materials aligned to NGSS and TEKS. I also spent 10 years in the classroom developing original high school biology and oceanography resources. Across both settings, I designed learning materials with an emphasis on clarity, accessibility, scientific accuracy, and classroom usability. I hold an M.Ed. in Curriculum and Instruction with a biology concentration, a B.S. in Marine Biology, and an active Virginia teaching license with a biology endorsement. I have written 200+ assessment items, created original Honors Biology course materials used by multiple teachers, and developed an eight-unit oceanography course aligned to Ocean Literacy principles. I also have experience building and organizing digital learning materials in LMS platforms and contributing content within CMS workflows. I’d be happy to support your next K-12 science project, whether you need help building new materials or strengthening resources you already have.
