Classifying Organisms

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

Lesson

Set out your lesson

Practise the bounded task in Classifying Organisms; see exact limits before inferring broader coverage.

Before teaching

Use this short check, then start teaching.

Activity

Can compare described characteristics; no culturing microbes or handling unknown organisms.

Policy

Exact directed source edges retained; earlier authorship is not learner attainment.

Printer, credit, and teaching notes

Exact directed source edges retained; earlier authorship is not learner attainment.

Materials

These supplied stage cards
Scrap paper and pencil; oral/pointing response where appropriate

Sequence

Read readiness and decide on support without treating prerequisite authoring as learner readiness.
Open Show first and explain its model.
Use Guided Try with support and its separate adult key.
Close Show and guided keys before Try, unless this Try is explicitly supported.
Reflect on an actual attempt, including help used.

No Printer

Use the supplied screen cards; copying the exact task to paper is optional, not required.

Privacy

Use only invented scenarios and optional anonymous local notes. Do not request names, photos, family finances, medical data, accounts or uploads. Stop uncomfortable physical activity.

Use the complete materials on screen or print only the current sheet. Keep adult guidance out of learner view.

Before you open

Ask the learner what they changed in the sim or page and what they observed.

Check understanding

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

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