Overview

In this final lesson of the unit, students investigate how aquaponics combines aquaculture and hydroponics to form a sustainable food system. They model how nutrients move from fish to plants and back to the fish.

Learning intentions

• Students will explain how aquaponics integrates aquaculture and hydroponics.
• Students will describe the symbiotic relationship between fish and plants.
• Students will explain how nutrients cycle in an aquaponics system.

Success criteria

• I can name the main parts of an aquaponics system (fish tank, grow bed, water pump/filter, plants).
• I can describe how fish waste becomes plant nutrients.
• I can explain why plants help keep water healthier for fish.
• I can use simple diagrams to show the nutrient pathway.

Curriculum links

• Science understanding: relationships between living things and how systems support life.
• Earth and space/science as a body of knowledge: how matter moves through and between parts of a system.
• Science inquiry skills: planning and conducting investigations, using evidence to explain phenomena.
• Scientific literacy: using diagrams and explanations to communicate ideas.

Lesson structure (45 minutes)

1. 0–5 min | Hook & recall

• Display a simple “fish → water → plants → back to fish” flow picture and ask: “Where do plants get their food in aquaponics?”
• Quick class recap of lesson 1 and 2: fish needs oxygen and clean water; plants need nutrients and light.

2. 5–12 min | Mini-lesson: how aquaponics works

• Teach using visuals and a labelled diagram: fish produce waste; beneficial bacteria convert waste into plant-usable nutrients; water circulates through grow beds; plants filter the water; water returns to the fish tank.
• Emphasise symbiosis: fish benefit from cleaner water; plants benefit from nutrients.

3. 12–28 min | Build & model (hands-on)

• In groups of 4–5, students build a mini aquaponics model using provided materials (e.g., clear container for fish tank, small tray for grow bed, tubing or a paper “pipe” route, card labels for bacteria, plants).
• Students role-play the system: one student is “fish” (adds waste), one is “bacteria” (changes it), one is “plants” (take up nutrients), one is “water pump” (moves water), and one is the “observer” (records the correct sequence).
• Teacher circulates, checking that each group can state the correct order and purpose of each component.

4. 28–36 min | Diagram & explain (individual)

• Students complete a simple “nutrient cycle in aquaponics” diagram using sentence starters:
• “Fish produce…”
• “Bacteria change… into…”
• “Plants use… to…”
• “Plants help… so fish…”
• Provide an infographic template for students who benefit from visuals, and a blank version for students ready to extend.

5. 36–43 min | Share & refine explanations

• Two or three groups share their model explanations. Class discusses using “I agree because…” and “I wonder if…” to improve scientific communication.
• Teacher prompts corrections: water movement, role of bacteria, and how plants improve water quality.

6. 43–45 min | Exit ticket

• Students answer one question on an exit slip: “Explain how fish and plants support each other in aquaponics.”
• Collect for quick formative assessment.

Resources

• Teacher-made labelled aquaponics diagram and flow chart (dyslexia-friendly font).
• Group mini model materials: clear container, small tray, paper/card “pipe” or tubing, label cards (fish, pump, bacteria, plants), markers.
• Sticky notes or sentence starter strips for the model role-play.
• Individual diagram templates: infographic version and standard version.
• Coloured water or safe colouring-in packets to show “nutrients” moving (optional).
• Exit ticket slips (dyslexia-friendly font).
• Reading options: short text at 3 reading levels with matching images.

Assessment

• Formative: teacher observation during model role-play (correct sequence and functions of components).
• Formative: individual nutrient-cycle diagram and sentence starter responses.
• Summative for this lesson: exit ticket explanation of the fish–plant support relationship.

Differentiation

• Kinesthetic support: mini-aquaponics model building and role-play (students learn by doing).
• Reading support: provide three-level texts with the same key ideas; allow students to choose which level they use.
• Dyslexia-friendly options: infographic templates, large spacing, dyslexia-friendly font, minimal text per box, colour-coded labels.
• Extension support/extension: advanced students add one extra detail (e.g., oxygen needs for fish, the purpose of filtration, or how light affects plant growth).

Extension (optional)

• Advanced learners research successful aquaponics systems around the world and prepare a short presentation (poster, slide, or spoken report) on:
• where the system is located,
• which crops and fish are used,
• what design features help it stay balanced.
• Include a simple “system diagram” in their presentation showing nutrient flow and components.
• Teacher provides a checklist: “Has nutrient pathway, named components, and one evidence-based example.”

3-Lesson Music Program

Overview

A short 3-lesson music sequence aligned to the South Australian Curriculum’s emphasis on creating and responding to sounds through purposeful practice, with clear dispositions (confidence, focus, collaboration, and respectful listening). Designed for a teacher with limited music knowledge.

Lesson 1: Listening & Patterns (45 min)

• Dispositions: curiosity, perseverance, listening respectfully.
• Students will explore rhythm and pattern by clapping and responding to short teacher-led phrases.
• Steps:
• Warm-up: body percussion echo game (teacher claps, students echo).
• Introduce a 4-beat rhythm pattern; students practise in small groups.
• “Sound sorting”: students listen and classify sounds as fast/slow, loud/quiet.
• Exit: students demonstrate the pattern using claps or taps.

Lesson 2: Create a Simple Beat (45 min)

• Dispositions: teamwork, confidence, taking responsibility for your role.
• Students will create a 4-beat accompaniment using percussion instruments or body percussion.
• Steps:
• Review rhythm pattern from Lesson 1.
• In groups, assign instruments (or “tap roles”) and practise together.
• Add a call-and-response: one group plays, another answers.
• Exit: brief performance to another group.

Lesson 3: Perform & Reflect (45 min)

• Dispositions: respect, growth mindset, reflection.
• Students will perform their group rhythm and describe how they improved.
• Steps:
• Warm-up: rhythmic warm-up and tempo check.
• Groups perform their 4-beat pattern plus a response.
• Reflection: students complete one sentence starter: “We improved by…”
• Exit: self-rating for collaboration (e.g., listened, took turns, kept time).

If you’d like, tell me what music resources you have (e.g., classroom percussion, drums, apps, or only body percussion) and I’ll tailor instruments and routines for your room.
