Evidence-Based Classification

PROCEDURAL

Science›Ecosystems & Habitats|Ages 10—11|ID: mt_B8lX8OCzGu

Give reasons for classifying plants and animals based on specific characteristics, using evidence to justify classification decisions

Mastery Evidence

Classify an unfamiliar organism using specific observable characteristics with reasoning
Compare two similar organisms and explain which characteristics distinguish their classification
Justify a classification decision using at least two pieces of evidence from observation

Assessment Prompt

“If [child] finds an unusual creature, can they explain step by step how they'd work out what group it belongs to based on its features?”
