Sycamore Seeds & Growth

Lesson Overview

Duration: 60 minutes
Class Size: 25 students
Age Group: Year 3 (8-9 years)
Curriculum Framework: Irish Primary Science Curriculum (1999) - Strand: Living Things and Strand: Materials (Plant Growth and Properties)

---

Curriculum Alignment

• Strand: Living Things
  • Strand Unit: Plant Growth and Care (Growth and Development of plants)
• Strand: Materials
  • Strand Unit: Properties and Characteristics of Materials (Relating to shapes and functions of materials)

Relevant Learning Outcomes (Based on IE Curriculum):

• Observe and explore the shape and movement of sycamore helicopter leaves as a seed dispersal mechanism.
• Evaluate and record variations in growth of pumpkins.
• Observe and describe growth patterns of vegetables in controlled environments (poly tunnel).
• Begin to develop investigative and observational skills through guided discussion and hands-on activities.

---

Lesson Objectives

By the end of the lesson, students will:

1. Describe the shape and movement of sycamore helicopter leaves and explain how these features help in seed dispersal.
2. Compare and evaluate differences in pumpkin growth, offering simple explanations for variations observed.
3. Observe and identify stages of vegetable growth in a poly tunnel environment.
4. Record observations using simple diagrams and discussion.
5. Develop curiosity and respect for plants’ life cycles through experiential learning linked to their recent farm visit.

Resources Needed

• Actual sycamore helicopter leaves (collected during the farm visit)
• Pictures or models of sycamore seeds in motion
• Pumpkin growth measurement charts (students’ own from farm visit or prepared data)
• Photos / examples of vegetables growing in a poly tunnel
• Whiteboard and markers
• Clipboards, observation worksheets for children
• Paper and colouring materials (crayons, pencils)
• Fan or open space for leaf flight demonstration

---

Lesson Structure

1. Introduction and Recap (10 minutes)

• Gather the students in a circle.
• Ask open-ended questions:
  • “Who remembers the sycamore helicopter leaves from our farm visit? What did they look like?”
  • “Can you remember how the seeds got from one place to another?”
• Show actual sycamore leaves and demonstrate spinning them between fingers or under a fan.
• Explain that the unique shape helps the seed “fly” away from the tree to find new places to grow.
• Highlight the connection to seed dispersal (a key plant survival strategy).

IE Competency: Developing curiosity and questioning (Strand: Living Things, Skill Development)

---

2. Sycamore Leaf Shape and Movement Activity (15 minutes)

• Hand out collected sycamore seeds to pairs of students.
• Take students outside or to a spacious area inside.
• Challenge students to drop their helicopter seeds and observe how they spin and move through the air.
• Ask them to discuss in pairs: “How does the shape affect its movement and where it lands?”
• Regroup and brainstorm as a class: Document observations on the whiteboard with simple diagrams.

Learning Outcome: Understanding how form ties to function in nature (seed dispersal).
Assessment: Informal questioning and observations recorded.

---

3. Evaluating Pumpkin Growth (15 minutes)

• Using pumpkin growth records (photos, simple data or students’ own observations from the farm), guide the class to review and compare sizes, colours, and shapes.
• Discuss:
  • “Why do you think some pumpkins grew bigger or smaller?”
  • “What might plants need to grow well?”
• Introduce terms like sunlight, water, soil nutrients in simple language.
• Students complete a simple worksheet where they rank 3 pumpkins from smallest to largest by size and colour, and write/draw one reason why.

Learning Outcome: Begin evaluation of plant growth and environmental effects (Living Things strand).
Assessment: Completed worksheets and participation in discussion.

---

4. Observing Vegetable Growth in the Poly Tunnel (15 minutes)

• Show photos or videos of the poly tunnel and vegetables growing inside.
• Discuss environmental benefits: warmth, protection, steady moisture.
• Ask students to identify different stages of growth (seedling, young plant, mature vegetable).
• If possible, bring a small plant or sprout to class for hands-on observation.
• Students complete an observation diary page:
  • Draw the vegetable stages.
  • Write one sentence about what plants need to grow in the tunnel.

Skill Development: Accurate observation and relating environment to plant growth.

---

5. Conclusion and Reflection (5 minutes)

• Recap key learnings by asking:
  • “How do sycamore seeds travel to new places?”
  • “What did we learn about pumpkin growth?”
  • “How does the poly tunnel help vegetables grow?”
• Praise effort, encourage questions.
• Mention that the next farm visit topic will explore insect pollinators.

---

Differentiation

• Provide extra support with writing tasks for children with additional needs (e.g. sentence starters or drawing only).
• Challenge more able learners to predict what might happen if pumpkins got no water or sunlight.

---

Follow-Up Ideas

• Plant more seeds in the classroom and monitor growth over weeks.
• Create a “seed dispersal” art project using paper helicopters.
• Setup a simple classroom poly tunnel using plastic bottles to observe seedling growth.
