BUILD · SCIENCE · Lesson 1 of 7

Make a guide another pupil can use

Learning intention

Identify roots, stem, leaves and flower from plant structures, while distinguishing hidden from absent.

Identify the part.

Point to your evidence.

Success looks like

  • Name the four main parts.
  • Locate parts on a different plant shape.
  • Use “not visible” when a view hides evidence.

Notice the structure

1. Is a plant living?

2. Name one plant part you know.

3. Can a container hide part of it?

I do

BUILD · SCIENCE · Lesson 1 of 7

I identify the part, then label it

Roots branch below the soil.

Stem connects the parts.

Leaves and flower attach above.

Find the four main partsA schematic flowering plant with roots below the soil, an upright stem, leaves attached to the stem and a flower above. Label leaders stop at the named structures.A RootsB StemC LeavesD FlowerSimplified flowering plant; shapes and sizes vary.

I keep names when shapes change

Leaves can have different shapes.

A flower need not be large or bright.

Identify by structure and positionTwo simplified flowering plants have different leaf shapes and flower appearances, while both possess roots, stems, leaves and flowers. Colours alone do not define the part.Different shapes can have the same part name.FlowerSmall greenflowerNarrow leavesBroad leaves

BUILD · SCIENCE · Lesson 1 of 7

I separate seen from hidden

I can see the stem and leaves.

The pot hides the roots.

No flower is visible today.

Hidden is different from absentA shoot appears above an opaque pot. The pot hides its roots. No flower is visible in this observation, which cannot establish that the plant never flowers.Leaves and stemare visible.Roots are hiddeninside the pot.Observation: no flower is visible today.This view cannot tell us whether it flowers at another time.

Atlas partners: point, name, check

Go to interactive investigation

Use records A–D.

One partner names a part.

The other checks its location.

Simplified atlas clues; not all plants look identical
CodeClue
ABranches below soil
BUpright connecting part
CFlat parts attached to B
DPetalled structure here

Build the plant atlas

Choose a part name or careful observation, then inspect the labelled model. Paper locations A–E provide the same clues.

Decision 1 of 3

Which name belongs to A, below the soil?

Choose, test, then explain together. Evidence diagrams appear only after your test. Diagram transitions explain the model; they do not represent real elapsed time. Use Pause model to stop transitions and model controls, or your device’s reduced-motion setting. The printed We do activity provides the paper route.

Three final checks

E1. Name the branching part usually below soil.

E2. Name the part that bears leaves.

E3. Does no visible flower prove a plant never flowers?

My science task sheets

Choose one route with your teacher. Shared evidence and the exit sheet appear in every route. Your work stays here while the page is open; save it before closing.

Shared evidence • Atlas clues

Identify A–D on this simplified plant. Use location and shape clues.

Identify A–D on the plantSimplified flowering plant with letter-only leaders: A points to branching roots below soil, B to upright stem, C to leaves, D to flower. Names are for pupils to supply.A __________B __________C __________D __________Simplified flowering plant; shapes and sizes vary.
Identify A–D on the plant
Diagram description

Simplified flowering plant with letter-only leaders: A points to branching roots below soil, B to upright stem, C to leaves, D to flower. Names are for pupils to supply.

E • Observation record: a potted shoot has a visible stem and leaves. Its roots are hidden by the pot; no flower is visible today.

Route 1 • Build the label key

Word bank: roots / stem / leaves / flower.

S4. E lets us say...

Route 2 • Make the atlas page

Draw a simple plant. Accuracy of labels matters more than artistic detail.

Route 3 • Review an unfamiliar view

A photograph shows a tall green stem with narrow leaves. Its base is outside the frame; it has no open flower.

Exit and reflection

Point, draw, write or tell an adult.

Slide 1

TA Brief

Current stage

Objective

Identify roots, stem, leaves and flower from plant structures, while distinguishing hidden from absent.

Preparation

Method precautions

Practical alternative

All core reasoning uses the supplied evidence and can be completed in 40 minutes without a live practical.

Access and regulation

Supported: Short choices, word bank and pointing or adult-scribed reasons; same core scientific goal.

Standard: Make a short evidence-based explanation or record using the supplied information.

Stretch: Apply the core idea to a changed case, evaluate evidence or identify a limit.

Regulation: Preview the sequence. Offer seated observation, quiet paired rehearsal, private feedback and a pass from public sharing. Routes respond to current access needs, not a diagnosis.

Teacher answers

Retrieval 1–3

1 yes. 2 any correctly named plant part. 3 yes.

We do W1–W2

W1 A roots, B stem, C leaves, D flower. Location clue: roots branch below the soil, leaves attach along the stem, or flower has petals in this example. W2 roots are hidden by the pot and no flower is visible today; do not infer absence or never flowering.

Hinge

Second option correct. Green colour alone is not a part identifier; hidden roots cannot be judged absent.

S1–S5

S1 roots. S2 stem. S3 leaves and flower respectively. S4 roots hidden. S5 any correctly named part with appropriate position if drawn.

M1–M4

M1 roots connected below stem, leaves attached to stem, flower attached above; accept variations. M2 flat structure attached to stem, combined with other visible clues. M3 stem or some flowers. M4 e.g. roots cannot be seen inside the pot; no flower is visible at this time.

T1–T4

T1 stem and leaves. T2 the base is outside the photograph. T3 no open flower is visible in this photograph. T4 e.g. a wider whole-plant view including base and a permitted root diagram or transparent-container view; a close view of an open flower at another appropriate time. Do not require uprooting.

Exit E1–E3

E1 roots. E2 stem. E3 no; flowering depends on species, maturity and season, among other conditions.

R1–R2

Responses vary. Credit a scientific revision, evidence-based defence or relevant next question. A private or oral response has equal value.

Cold Call

Give thinking time. Invite a response by voice, pointing or showing work. A pupil can pass; check in privately when useful.
