Butterfly Life Cycle

Overview

This 45-minute lesson is the second in a four-part unit titled Exploring Life Cycles, designed for Year 2 students (ages 6-7) and aligned with the National Curriculum for Science in England. The lesson will deepen students’ understanding by focusing on the butterfly’s life cycle stages: egg, larva, pupa, and adult. Students will engage with audiovisual materials and hands-on diagram creation to consolidate their knowledge.

Curriculum Links

• Science – Key Stage 1 (Years 1-2):
  • Animals, including humans: Pupils should be taught to identify and name a variety of common animals including insects, and describe their basic needs and life cycles.
  • Working scientifically: Asking simple questions; observing closely; performing simple tests; using observations to answer questions.

---

Learning Outcomes

By the end of the lesson, students will be able to:

1. Name and sequence the four stages of a butterfly’s life cycle.
2. Describe simple characteristics of each stage (egg, larva/caterpillar, pupa/chrysalis, adult butterfly).
3. Create a labeled diagram illustrating the butterfly life cycle accurately.
4. Demonstrate curiosity and care for living things through observation and discussion.

Resources Needed

• Projector or interactive whiteboard
• Time-lapse video of butterfly metamorphosis (silent playback recommended for focused observation)
• Printed diagram templates (circle layout with four segments)
• Colouring pencils/crayons
• Butterfly life cycle flashcards with images and key facts
• Whiteboard and markers
• Sticky notes (for questions/thoughts)

Lesson Structure

1. Starter Activity: Recall & Connect (5 minutes)

• Begin with a quick recall quiz using flashcards from Lesson 1 (general life cycles) to spark prior knowledge.
• Ask: “Can anyone name an animal that changes a lot as it grows?” Prompt to guide toward butterflies or insects.
• Introduce today’s focus: the butterfly’s life cycle.

2. Input & Exploration: Time-lapse Video (10 minutes)

• Play a time-lapse video showing the complete life cycle of a butterfly. (Ensure video is age-appropriate and visually clear.)
• Pause at each stage to check understanding, using questions like: “What did you see happen here?” or “What do you think this part is called?”
• Display flashcards to reinforce vocabulary: egg, larva/caterpillar, pupa/chrysalis, adult butterfly.

3. Guided Activity: Diagram Creation (20 minutes)

• Distribute a circular diagram template divided into four sections.
• Working in pairs (to encourage peer discussion), students draw and label each stage using supplied picture cues and vocabulary.
• Encourage students to colour and decorate their diagrams to reflect their observations from the video.
• Circulate to prompt with questions such as “Why is the pupa stage important?” or “What changes happen to the caterpillar before it becomes an adult?”

4. Reflection and Sharing (7 minutes)

• Pairs share their diagrams with the class, explaining each life cycle stage in their own words.
• Use the whiteboard to compile key words and interesting facts voiced by students.
• Introduce ‘wonder questions’ on sticky notes for students to ponder over the unit, e.g., “Why do you think some insects have life cycles with very different stages?”

5. Plenary: Quick Quiz & Exit Ticket (3 minutes)

• Conduct a quick verbal quiz to consolidate key vocabulary and sequence order.
• Students write one new thing they learned on a small paper ‘exit ticket’ before leaving.

Differentiation & SEND Support

• Provide labelled visual cards and sentence starters for students needing language support.
• Allow alternative modes of expression: drawing, labelling, or assembling a physical model of the life cycle using playdough or cut-outs (if additional time/resources available).
• Use pair work to embed social learning and peer assistance.
• Repeat instructions clearly and check in frequently with quieter learners.

---

Assessment for Learning (AfL)

• Ongoing questioning and observation during video interaction and diagram work.
• Use exit tickets to assess understanding of life cycle stages and vocabulary.
• Peer feedback during sharing segment to enhance verbalisation and confidence.

---

Extension Ideas

• Set up a small butterfly habitat in the classroom and observe real caterpillars transitioning through stages over several days.
• Cross-curricular link: Write a short story or poem from the perspective of a caterpillar/butterfly.
• Science and art integration: Create a large, collaborative classroom mural of the butterfly life cycle.

---

Teacher’s Notes

• Ensure video volume and length are suited to young learners’ attention spans; consider breaking it for discussion pauses.
• Emphasise curiosity and respect for living creatures during all activities.
• Capitalise on the natural fascination children have with butterflies to encourage engagement and wonder about nature’s processes.
