Classroom Resources
Our lessons are designed for real classrooms and built on how students actually think.
Each resource helps students:
think clearly
explain their ideas with evidence
apply their thinking in meaningful ways
Sample lessons below.
What Makes a Strong Scientific Explanation (CER)
This lesson introduces students to Claim, Evidence, and Reasoning (CER) using clear examples, error analysis, and guided practice.
Students learn to:
make clear claims
support ideas with evidence
explain their reasoning
Built using cognitive science principles:
scaffolded learning (model → practice → apply)
error analysis to strengthen understanding
low cognitive load design
Building Strong Scientists: Measurement and Data Skills
This lesson helps students understand how scientists measure, convert, and interpret data using clear steps, guided practice, and error analysis.
Students learn to:
use the metric system with confidence
convert between units using patterns
explain how and why their answers make sense
Built using cognitive science principles:
scaffolded learning (model → guided practice → independent practice)
error analysis to strengthen understanding
reducing cognitive load through clear visual patterns
