Ocean Food Chain Journey

Overview

This lesson introduces preschool students to the concept of ocean food chains within the broader "Adventures in Ocean Habitat" unit. Through multi-sensory, visual, and interactive activities, students explore simple food chains featuring marine animals, supporting both scientific understanding and key competencies. This session is specially designed for autistic and sensory learners, with differentiated supports and dyslexia-friendly resources according to the New Zealand Curriculum Refresh guidance.

Subject: Science

Curriculum Links

Learning Area: Science (Te Mātaiaho | The New Zealand Curriculum Refresh)

Strand: Living World
Achievement Objective:
- "Explore and describe the relationship between living things in their environment." (adapted for preschool understanding)
Progress Outcome (Foundation/Years 0-3):
- Demonstrate curiosity about familiar living things.
- Recognise basic relationships between living things.
- Begin to use and understand simple scientific vocabulary (e.g., food chain, ocean, animals).

Key Competencies

Thinking: Make sense of the world by exploring how ocean creatures depend on each other.
Using Language, Symbols, and Text: Use pictures and words to identify marine animals and their roles.
Relating to Others: Engage collaboratively around shared learning tasks.
Managing Self: Participate with confidence through supported sensory activities.
Participating and Contributing: Share ideas about ocean life.

WALT (We Are Learning To)

Understand what a food chain is and how ocean animals depend on each other.
Build a simple ocean food chain using pictures and sequence it correctly.
Use new words like “predator,” “prey,” and “food chain” in context.

Success Criteria

I can name at least 3 ocean animals.
I can put ocean animals in order to show who eats whom.
I can explain that some animals eat plants and others eat animals.
I can participate in group activities and share my ideas.

Materials & Resources

Laminated pictures of marine animals (e.g., plankton, small fish, bigger fish, shark)
Velcro board or magnetic board for sequencing pictures
A simple illustrated chart of an ocean food chain
Sensory mats or textured ocean animal toys for tactile learners
Dyslexia-friendly printed word cards with visuals
Clear audio recordings of ocean sounds for sensory engagement

Lesson Plan Outline

1. Welcome and Sensory Warm-up (5 minutes)

Greet students and engage them with soft ocean sounds playing in the background.
Use a sensory mat or tactile ocean animal toys to help students feel textures related to ocean creatures.
Set up a calm zone for sensory breaks if needed.

2. Introduction to Ocean Food Chains (7 minutes)

Show an illustrated ocean food chain chart with pictures.
Explain simply: "This is called a food chain. It shows who eats whom in the ocean."
Use clear, slow speech and paired picture cards.
Model the chain: plankton → small fish → bigger fish → shark.
Ask students to repeat key vocabulary: “food chain,” “eat,” “animal,” “plant.”

3. Interactive Group Activity: Build the Food Chain (10 minutes)

Distribute laminated animal pictures.
With teacher guidance, students take turns placing their animal pictures in order on the Velcro/magnetic board.
Use sentence stems: "Who does the ___ eat?" "The ___ eats ___." to scaffold communication.
Encourage tactile interaction with pictures and verbal sharing.
Use thumbs-up or visual "yes/no" cards to check understanding.

4. Story-time Reinforcement (5 minutes)

Read a simple, dyslexia-friendly book or story about ocean animals and their food chain roles, supported by pictures and repetitive language.
Pause for questions and short discussion, encouraging students to point to animals in their food chain.

5. Review and Reflection (3 minutes)

Recap key points using the sequence board and pictures.
Invite students to share something they learned.
Provide positive, specific verbal feedback.
Offer a calm sensory activity if students wish to explore textures or sounds again.

Differentiation Strategies for Diverse Learners

For sensory-seeking learners: Incorporate tactile materials (e.g., textured animal cards, water play with ocean animal toys).
For learners with auditory sensitivities: Provide noise-cancelling headphones or allow participation in quieter spaces.
For non-verbal or reluctant communicators: Use picture exchange communication system (PECS) or gesture-based responses.
For learners needing repetition: Use repeated exposure to vocabulary with multi-sensory supports.
For visual learners: Use high-contrast, clear images with labels.
For those requiring structure: Provide a visual schedule of the lesson steps using icons.

Extension Activities for Advanced Learners

Create a more complex food web by introducing additional ocean animals (e.g., seaweed, crabs, seals).
Use digital tablets with interactive ocean food chain games.
Develop simple role-plays where students act out different ocean animals in the chain.
Encourage drawing and labelling their own ocean food chain pictures.
Introduce the concept of humans affecting ocean food chains (e.g., pollution) in a simple way.

Assessment (Formative)

Observation notes on student participation in sequencing activity.
Anecdotal records of student use of vocabulary.
Checklists for success criteria attainment.
Informal questioning during story-time for comprehension.
Sensory engagement levels as indicators of comfort and attentiveness.

Teacher Reflection Prompts

Did students engage with the sensory materials and sequencing task?
Which vocabulary terms were most accessible or challenging?
Were differentiation strategies effective in including all learners?
How did students respond to the group and individual activities?
What adjustments are needed for the final lesson in the unit?

This lesson plan blends curriculum-aligned scientific concepts with intentional sensory-accessible approaches, fostering curiosity and understanding of ocean food chains for young and diverse learners in New Zealand preschool settings.
