Seed Growth Stages

Overview

This is lesson 4 of 9 in Seeds: Life’s Beginnings. Students build on prior learning about seeds and germination by examining the next stages of plant growth from seedling to mature plant. They create a visual timeline to show how plants develop over time.

Learning intentions

• WALT identify the main stages in a flowering plant’s life cycle after germination.
• WALT describe how plant structures change as a plant grows (seedling to mature plant).
• WALT use observations and science vocabulary to create a clear visual timeline of growth stages.

Success criteria

• I can name at least 4 growth stages after germination.
• I can match each stage to key changes in the plant (e.g., leaves, stem, height/size).
• I can create a visual timeline that shows the stages in the correct order.
• I can explain my timeline using complete sentences and key science words.

Curriculum links

• Biological Science — Life cycles: Plants grow from seeds, mature, and reproduce.
• Biological Science — Life cycles: Seeds germinate and seedlings develop into mature plants.
• Te Reo/Language of science: students use diagrams and representations to communicate scientific ideas.
• Science capabilities: developing scientific understanding through observation, representing ideas, and communicating findings.

Lesson structure (30 minutes)

1. 0–4 min · Hook (Think–Pair–Share). Teacher shows 3–4 labelled plant photos (seedling, young plant, larger plant, mature plant) and asks: “What do you think happens next after germination?” Students think, then discuss with a partner and share one idea with the class.

2. 4–10 min · Direct teach (Growth stages as a sequence). Teacher briefly models a “stage after germination” storyline: seedling → early growth/leaf growth → bigger plant (more leaves/stem) → mature plant. Students record the stage names in their books in order using the board format.

3. 10–20 min · Visual timeline creation (Make). Teacher gives each student a timeline template with 4–5 boxes and sentence starters; they also provide a word bank (e.g., seedling, leaves, stem, root, grow, mature, longer, bigger). Students complete their visual timeline: draw or paste a simple diagram in each box, add a short caption, and include an “order” arrow or number.

4. 20–26 min · Gallery share (Communicate). Teacher organises a quick “walk and look” where students view 2–3 timelines and leave one “Glow” (what’s clear) and one “Grow” (what to improve). Students make one improvement based on feedback during the share.

5. 26–30 min · Exit ticket (Check for understanding). Teacher asks students to answer: “Write the stages after germination in order, and choose one change you would expect to see at a particular stage.” Students submit responses as their exit ticket.

Resources

• Print or digital timeline template (4–5 boxes) for “after germination”
• Word bank cards and/or enlarged label cards
• 3–4 labelled growth-stage images (seedling to mature plant)
• Coloured pencils/markers, scissors, glue (if using cut-outs)
• Sentence starters (e.g., “In the seedling stage, the plant…”, “Next, the plant…”, “A mature plant…”)
• Student science notebooks or worksheets
• Dyslexia-friendly reading support: high-contrast versions, fewer words per line, and option to use icons/symbols

Assessment

• Teacher circulates during timeline creation, checking that students can: (1) name stages, (2) keep correct sequence, (3) include key changes.
• Gallery share feedback is used to identify common misconceptions (e.g., mixing up seedling vs mature plant).
• Exit ticket confirms understanding of stage order and at least one observable change.

Differentiation

• Support for students who need scaffolding:
• Provide a partially completed timeline with stage names already placed.
• Offer sentence starters and a word bank with pictures (e.g., seedling icon + “leaves” icon).
• Allow students to choose drawing vs cut-and-label option.
• For EAL learners:
• Use labelled images and consistent sentence frames; encourage students to rehearse explanations with a partner before writing.
• For students needing additional challenge within the task:
• Require one “because” sentence (e.g., “The plant is mature because it has more leaves and is bigger.”).
• For advanced learners:
• Add a 5th box for “reproduction stage” as a preview (or include “flower/seed formation” as a note if images are available).
• Ask students to include a time estimate range (e.g., “weeks to months”) and explain that growth depends on conditions like water and light.
• Dyslexia-friendly reading options:
• Provide text in large font, high contrast, and short lines; offer audio read-aloud for stage descriptions; allow students to use icons and minimal text with clear labels.

Extension (optional)

• Not included (not requested).
