Flowering Plant Life

Overview

In this lesson, students learn the life cycle role of flowers in flowering plants, focusing on key flower parts, their functions, and the pollination process. They will use simple models to explain how pollen is transferred and link this to seed formation.

Learning intentions

Students will be able to:

• WALT describe the main parts of a flowering plant (roots, stem, leaves, flowers) and identify flower parts.
• WALT explain the function of flowers in a flowering plant’s life cycle.
• WALT describe pollination as the transfer of pollen from the male part to the female part.
• WALT give a simple cause-and-effect explanation of how pollination leads to seed formation.

Success criteria

• I can name at least 3 parts of a flowering plant and state what each one does.
• I can name and locate key flower parts (pollen-producing and ovary/female parts) in a diagram or model.
• I can explain, in my own words, what pollination is and why it matters.
• I can sequence: pollination → fertilisation → seed formation (in simple terms).

Curriculum links

• UK NC Science (Year 4): Living things and their habitats — plants grouped into categories, including flowering plants.
• UK NC Science (Year 4): explore the part that flowers play in the life cycle of flowering plants, including pollination, seed formation and seed dispersal.
• Working scientifically: use observations and models to describe processes and explain what happens.

Lesson structure (60 minutes)

1. 0–5 min · Hook and question. Teacher shows pictures of different flowers and asks, “Where do seeds come from?” Students turn-and-talk to share ideas.

2. 5–15 min · Direct teach: plant and flower parts. Teacher builds a class diagram of a flowering plant, then a close-up of a flower, pointing out pollen-producing and ovary/female parts. Students label a simple worksheet diagram (teacher modelling first, then independent).

3. 15–25 min · Key concept: what flowers do. Teacher explains that flowers help flowering plants reproduce and make seeds, linking flower parts to roles. Students highlight the words “pollen”, “female part”, “ovary”, and “seeds” on a mini fact card.

4. 25–40 min · Model activity: pollination simulation. Teacher gives each group a simple “pollen transfer” kit: cotton wool/pom-poms as pollen, tweezers or small paintbrushes as “insect/transfer”, and paper flowers with marked pollen spots and female part targets. Students follow a 3-round challenge:

• Round 1: “Insect visits” a flower (collect pollen).
• Round 2: “Insect moves pollen” to another flower (deposit).
• Round 3: Groups record which flowers received pollen and predict what will happen next (seed formation).

5. 40–50 min · Whole-class reasoning: cause and effect. Teacher leads a discussion using student results: “If pollen reaches the female part, what comes next?” Students complete a sequencing strip: pollination → fertilisation (simple mention) → seed formation.

6. 50–58 min · Quick knowledge check (paired). Teacher uses 4 short prompts on the board (e.g., “Pollination is…”, “Flowers are for…”, “Pollen goes to…”, “Seeds form when…”). Students answer using sentence stems on cards.

7. 58–60 min · Exit ticket. Each student writes one sentence: “Pollination happens when…” and one sentence: “This helps the plant to…”

Resources

• Flower and flowering plant picture cards (teacher slide or printed)
• Student worksheet: flowering plant diagram + flower parts diagram
• Mini fact cards (pollen, pollination, seed formation)
• Group “pollination kit”: paper flower templates, cotton wool/pom-poms (pollen), tweezers/small paintbrushes (transfer tools), sticky notes or recording sheets
• Sequencing strip cards for pollination → fertilisation → seed formation
• Sentence stem cards for assessment prompts
• Exit ticket slips and pens

Assessment

• During worksheet labelling: check for correct identification of plant parts and flower roles.
• During pollination simulation: observe whether students can describe pollen transfer and link it to seed formation.
• Exit ticket: collect sentences to assess understanding of pollination as pollen transfer and its purpose.

Differentiation

• Support:
• Provide sentence stems and a word bank on the worksheet.
• Offer a partially labelled diagram for students who need it.
• Use think-alouds during the modelling of the flower parts.
• Challenge/extension:
• Ask groups to predict what would happen if pollen did not move (e.g., “What might stop seed formation?”).
• Encourage use of “male/female parts” language accurately.
• EAL/SEN:
• Use visuals consistently (same colour for pollen vs target female part).
• Pair students strategically for the simulation so roles are clear (collector, transfer, recorder).
• Allow verbal responses before writing for the exit ticket.
