Aquaculture Beginnings

Overview

Students are introduced to aquaculture as a way humans grow aquatic animals and plants for food and other purposes. They explore examples of species that can be farmed, with a focus on yabbies as a familiar Australian organism.

Learning intentions

• Students will understand what aquaculture means and why people use it.
• Students will identify different types of aquatic species grown in aquaculture.
• Students will describe how yabbies can be part of an aquaculture system.

Success criteria

• I can explain what aquaculture is in my own words.
• I can name at least three types of species grown in aquaculture.
• I can show understanding that yabbies are an aquatic organism used in aquaculture.

Curriculum links

• Science understanding: living things can be grouped based on observable features, including where they live.
• Science as inquiry: students ask questions, make observations, and share ideas using age-appropriate language.
• Science communication: students use diagrams/pictures and oral explanations to communicate scientific ideas.
• Sustainability and food systems awareness: recognising how humans meet needs for food using natural resources responsibly.

Lesson structure (45 minutes)

1. 0–5 Hook: Food from water

• Teacher shows a short image slide sequence: yabbies, fish, prawns, seaweed, and simple “wild catch vs farm” visuals.
• Students do a quick turn-and-talk: “Where might these foods come from?”

2. 5–12 Mini-lesson: What is aquaculture?

• Define aquaculture in student-friendly terms: growing aquatic organisms (animals and plants) in managed systems.
• Explain that aquaculture can happen in tanks, ponds, or cages, and is different from catching wild animals.
• Focus example: yabbies—why they are suitable for farming (students discuss what they think: freshwater habitat, hardiness, food value).

3. 12–20 Species sort activity (picture cards)

• In small groups, students sort picture cards into categories: “aquaculture species” and “not aquaculture / unsure.”
• Students then select three cards and record (or dictate) the names using sentence starters: “Aquaculture includes …”
• Teacher circulates and checks understanding with brief questioning.

4. 20–29 Aquaculture system thinking: simple model

• Students complete a guided diagram template: “Aquaculture system” with three labelled parts (organisms, water habitat, humans who manage).
• Include a teacher-led discussion: what aquaculture needs to support living things (water, food, care).
• Students add one yabbies-related detail (e.g., “yabbies live in freshwater”).

5. 29–38 Interactive check: Teach-back

• Each group shares one species card and one reason it could be farmed.
• Whole class creates a class list of aquaculture species (at least three) and a class definition of aquaculture.
• Teacher uses the success criteria language: “Can we all explain aquaculture and name three species?”

6. 38–45 Exit ticket

• Students answer individually (or with support):
• “Aquaculture means …”
• “Three aquaculture species are …, …, …”
• Collect for quick formative assessment for the next lesson.

Resources

• Large image cards of aquaculture species (yabbies, trout or prawns or fish, seaweed/other aquatic plants) and “not aquaculture/uncertain” cards
• Picture/word sentence starters and simple definition poster: “Aquaculture = growing aquatic organisms in managed systems”
• Guided diagram template: aquaculture system with spaces for organisms, water habitat, human management
• Coloured pencils/crayons, scissors, glue sticks
• Audio device/teacher phone for reading instructions aloud (dyslexia-friendly option)
• Audio recording of key terms and sentence starters (teacher-prepared)
• Sticky notes for group sharing and exit ticket
• Access to short teacher slideshow (no links required)

Assessment

• Formative: teacher observation during the species sort and guided diagram (check for correct species naming and correct meaning of aquaculture).
• Formative: teach-back discussion—listen for whether students use aquaculture language accurately.
• Summative for Lesson 1: exit ticket demonstrating the definition of aquaculture and naming at least three aquaculture species.

Differentiation

• Provide picture cards for EAL/D students and pair with word labels; allow pointing and oral responses for early language stages.
• Use simple, consistent vocabulary (aquaculture, aquatic, grow, manage, water habitat) and display it visually throughout the lesson.
• Dyslexia-friendly options: offer audio recordings of instructions and sentence starters; use visual aids (icons, picture cards, large posters) rather than relying on reading-heavy texts.
• For students with learning difficulties: provide a partially completed diagram and a reduced set of species cards (e.g., choose from 6 cards only).
• For extension (advanced learners): require an additional aquaculture species card and a one-sentence explanation of how that species would be supported in a system.

Extension (optional)

• Students research and present another aquaculture species not covered in class (example options: trout or prawns). Provide a simple “mini-poster” frame: Species name, where it lives (freshwater/saltwater), and one reason it can be farmed.
