About This Curriculum

OpenSciEd Biology is a free, open-source, high school science curriculum aligned with NGSS that emphasizes investigative science research, three-dimensional learning, and real-world applications. Students develop critical thinking skills through phenomena-based inquiry learning.

What makes it unique: First organization to earn all-green ratings from EdReports across all three high school courses (Biology, Chemistry, Physics); free, openly available, high-quality NGSS-aligned materials with robust professional learning support and accessibility features for all learners

OpenSciEd Biology: Open-Source NGSS-Aligned Inquiry Curriculum

OpenSciEd Biology is a free, open-source high school science curriculum that builds learning around phenomena-driven storylines and emphasizes three-dimensional NGSS integration. The curriculum uses heavily scripted, lengthy lessons that guide students through investigative processes while requiring strong reading skills and substantial teacher preparation time.

Best for

High school biology teachers comfortable with inquiry-based instruction who have adequate preparation time and students with strong reading abilities

Evaluation Criteria

2 strengths · 1 concern · 2 neutral · 2 insufficient evidence

Ngss AlignmentStrength

The OpenSciEd biology curriculum demonstrates excellent NGSS alignment with strong three-dimensional learning integration. EdReports confirms the curriculum meets expectations across all alignment gateways.

EdReports rated the curriculum as 'Meets Expectations' for NGSS alignment, coherence, and usability, with Learning List confirming design around Framework for K-12 Science Education and NGSS standards

Hands On IntegrationStrength

The curriculum strongly integrates hands-on investigations with learning objectives through structured inquiry approaches. Students conduct investigations as part of the phenomena-based storylines.

Reviews emphasize that students conduct investigations and explore phenomena as core components of the lesson structure, with EdReports confirming strong three-dimensional learning integration

Direct InstructionConcern

The curriculum emphasizes inquiry-based discovery over direct instruction, with heavily scripted lessons guiding exploration rather than explicit teaching. This may limit efficiency of content delivery.

Learning List characterizes lessons as heavily scripted and inquiry-based where students explore phenomena, suggesting guided discovery rather than direct instruction of concepts

Knowledge RichNeutral

The curriculum builds content knowledge through phenomena-based storylines that require students to explore, investigate, and support ideas with evidence. However, the inquiry-heavy approach may not provide sufficient explicit content instruction.

Learning List notes the program requires students to explore phenomena, conduct investigations, and support ideas with evidence, suggesting content is built through discovery rather than direct instruction

Teacher TrainingNeutral

The curriculum includes substantial teacher support materials but requires significant preparation time due to lengthy, heavily scripted lessons. Teacher materials focus strongly on NGSS implementation.

Learning List notes that lessons are heavily scripted and require ample teacher time to navigate materials, while EdReports confirms strong teacher support meeting expectations

Retrieval PracticeInsufficient Evidence

No evidence of systematic retrieval practice or spaced review components was found in the available reviews.

Neither EdReports nor Learning List mention quiz systems, recall exercises, or structured review practices

Scientific VocabularyInsufficient Evidence

Vocabulary instruction appears embedded within inquiry activities rather than explicitly taught. The text-dense materials suggest vocabulary exposure but unclear systematic instruction.

Learning List describes materials as text-dense requiring strong reading ability, but does not mention explicit vocabulary instruction approaches
