While OpenSciEd units are designed to support teachers who are new to three-dimensional learning, the Teacher Handbook offers a deeper look into the structure and features of the materials. It highlights key design elements and openly available resources on the website that may be unfamiliar—even to experienced educators. Each chapter focuses on a specific aspect of the curriculum, helping you build confidence and expertise as you implement the units.

The handbook is designed to help teachers deeply understand and implement OpenSciEd middle school units. Topics include:

• Unit Structure & Coherence:
  How each unit is intentionally sequenced to build disciplinary core ideas, science and engineering practices, and crosscutting concepts.
• Anchoring Phenomena & Driving Questions:
  Guidance on launching units with phenomena that spark curiosity and sustain student engagement through coherent question-driven learning.
• Instructional Routines & Talk Moves:
  Strategies for facilitating productive discussions, supporting equitable participation, and using classroom routines effectively.
• Student Sensemaking & Modeling:
  Tools for supporting student-driven investigations, modeling, and evidence-based reasoning.
• Assessment Tools & Purposes:
  An overview of embedded formative and summative assessments, including how they inform instruction and support learning goals.
• Instruction that Supports All Students:
  Suggestions for meeting the diverse needs of learners and promoting science identity development.
• Using the OpenSciEd Digital Materials:
  Tips for navigating the teacher edition, accessing editable resources, and leveraging professional learning supports.
