PhD Science TEKS Edition

Core K–5 Science Instructional Materials

Freely available in perpetuity

PhD Science TEKS Edition aligns with the Texas Essential Knowledge and Skills (TEKS) and English Language Proficiency Standards (ELPS). It is a phenomenon-based program in which teachers facilitate the learning, but students own it. Students develop a deep, lasting understanding of science concepts that inspires them to wonder about the world and empowers them to make sense of it.

Each lesson builds on the one before it, so students develop their understanding in the context of the phenomenon. The curriculum provides differentiation strategies to support engagement with rigorous content through hands-on investigations, collaborative conversations, and analysis of authentic texts and media.
