Three Dimension Science

I'm David Rosvally, a middle school science teacher with 24 years of classroom experience in Connecticut. I currently teach 7th grade Geology, Astronomy, Biology, and Chemistry at Weston Middle School, where my students consistently score 88% proficient and above on the NGSS 8th grade science assessment. I originally developed all of our district's 6th and 8th grade science units from scratch — years before we adopted OpenSciEd. When OpenSciEd arrived, my curriculum became the foundation for our district's implementation. I've since trained fellow teachers across the district on NGSS-aligned assessment practices and OpenSciEd implementation. Every resource in this store is built around the three dimensions of the NGSS — Disciplinary Core Ideas, Science and Engineering Practices, and Crosscutting Concepts — using real phenomena to drive student sensemaking. Covering all 18 middle school OpenSciEd units across grades 6–8. Three Dimension Science assessments are built using the criteria from the Achieve NGSS Science Task Screener — the professional standard used by curriculum leaders and instructional coaches to evaluate three-dimensional science task quality. Every assessment features a novel phenomenon-based transfer scenario, integrated SEP/DCI/CCC sense-making, and a complete teacher key with scoring look-fors, common misconception guidance, and rubrics connected to all three dimensions. No recall. No plug-and-chug. Just real science thinking. Student-Tested & Approved.
