Classifying Organisms

CONCEPTUAL

Science›Ecosystems & Habitats|Ages 10—11|ID: mt_IY3KwGLZgk

Describe how living things are classified into broad groups (micro-organisms, plants, animals) according to common observable characteristics, similarities, and differences

Mastery Evidence

Name the broad classification groups: micro-organisms, plants, animals (and fungi if known)
Describe observable characteristics used for classification (e.g. plants make own food, animals move and eat)
Give examples of organisms in each group, including micro-organisms like bacteria

Assessment Prompt

“Can [child] explain the big groups that scientists sort all living things into — like plants, animals, and tiny micro-organisms — and give examples of each?”
