Plant Parts Power

Overview

In this lesson (Lesson 3 of 6) students explore plant parts on a nature walk, then plan and write an acrostic poem using specific sentence thinking before writing. They also sketch detailed plant drawings to support clear, observable ideas.

Learning intentions

• WALT identify and name external plant parts (roots, stem, leaves, flowers/fruit) during a nature walk.
• WALT plan a short series of sentences and poem lines by talking and thinking carefully about each line before writing.
• WALT write an acrostic poem where each line starts with a letter from a plant parts word (e.g., LEAVES, FLOWER).
• WALT use a sketch to help plan and include accurate details.

Success criteria

• I can point to a plant part and tell how I know (using simple evidence from what I see).
• I can plan my acrostic lines by saying them first, then writing them.
• I can write an acrostic poem with each line starting with the correct letter.
• I can draw a clear sketch showing the plant part(s) I described.

Curriculum links

• Writing (Writing Processes — Planning): planning a short series of sentences through talk and thinking carefully about each sentence before writing it.
• Writing (Writing Processes — Planning): working towards a specific writing goal helps writers focus on particular areas for improvement.
• Science capability (Using evidence from observations): using observations from the nature walk to make statements and include details in writing.

Lesson structure (45 minutes)

1. 0–5 min · Hook + goal setting. Teacher shows 2 quick photo cards of plants/plant parts and asks: “What part of the plant do you notice first, and what do you see that makes you think that?” Students turn-and-talk, then share.

2. 5–12 min · Teach: identifying + sketching supports writing. Teacher introduces a simple plant-parts observing routine: look closely → name the part → notice one feature (shape/colour/texture) → decide where to label it on the sketch. Students practise with a provided printed plant diagram, labelling one part and adding one detail.

3. 12–28 min · Nature walk: notice and collect details. Teacher leads students in small groups to observe real plants (school garden/nearby safe area). Teacher prompts: “Find a leaf (or flower). What shape is it? What colour? Does it have edges? Where could we label this?” Students complete a quick “notice sheet” with 2 plant parts and 1 feature for each, then do one pencil sketch of the chosen plant part with a label. (Teacher circulates to check that they are naming external parts accurately.)

4. 28–34 min · Direct teach: planning the acrostic (talk first). Teacher models an acrostic plan on the board using one target word (e.g., LEAVES). Teacher thinks aloud: “My goal is to write 6 short lines. I will start line 1 with L. Before writing, I will say the whole line in my head and make sure it matches what I noticed.” Students help by suggesting short sentence fragments for two letters.

5. 34–42 min · Guided planning + writing: acrostic poem. Teacher distributes planning strips: “Word for my acrostic: ____ / My lines (say first, then write).” Students choose one plant-parts word (class options: LEAVES, STEM, FLOWER, ROOTS, FRUIT) and plan by whispering each line to themselves or a partner before writing it on the poem template. Target expectation: each line begins with the correct letter and includes one detail from their sketch/notice sheet.

6. 42–45 min · Share + exit check. Students do a “gallery share” (stand and read) in pairs or groups of 4. Teacher asks each pair to answer: “Which letter did you find easiest, and which line uses your best observation detail?” Students then hand in or show their completed acrostic template.

Resources

• Plant parts notice sheets (2 parts + 1 feature each)
• Pencil sketch paper with a simple label space
• Clipboards and pencils for nature walk
• Printed plant parts word cards (LEAVES, STEM, FLOWER, ROOTS, FRUIT)
• Acrostic poem templates with the chosen word written down the side
• Class anchor chart: “Look → Name → Feature → Label”
• Timer for walk planning and writing blocks
• Teacher phone/camera (optional) for quick photo prompts

Assessment

• During the walk: use a quick checklist to note whether students can correctly name at least one external plant part and identify a feature they observed.
• During planning/writing: observe whether students plan by speaking/thinking first and whether each acrostic line starts with the correct letter.
• Exit check: collect one acrostic template or use a 10-second teacher conference per group to confirm accuracy of plant part naming and letter matching.

Differentiation

• Support: provide sentence starters on templates (e.g., “L is for ___ because I saw ___.” / “S is for ___ with ___.”). Offer a model acrostic for each target word and a word bank of observable features (green, long, round, veiny, prickly, smooth).
• Support for reluctant writers: allow “sentence fragments” as long as they still start with the correct letter and include an observation detail.
• Extension: challenge students to add one extra line that explains how the plant part helps the plant (e.g., “E is for… it helps the plant drink.”) while keeping to the acrostic goal for the letter lines.
• EAL/SEN considerations: pre-teach key observation words with gestures (leaf, stem, roots, flower, smooth, rough). Allow oral planning with a partner before independent writing. Provide visual word cards during writing.
