Philosophy

� Engage Children in fun hands-on experience growing, harvesting and managing a garden;

� Allow Children to experiment;

� To provide pleasurable food education for students. The underlying belief is that by introducing this holistic approach we have a chance to positively influence children’s food choices in ways that have not been tried before;

� Develop Maths and Science skills;� Proficiencies of understanding, fluency, reasoning and

problem solving, inquiry skills;� Engage students in a practical way science;� Preparing students to use science for life teach

children to function effectively in a scientifically and technologically advanced society;

� Provides foundations leading to secondary science as well as future tertiary courses;

� Demonstrate a sustainable model to the school and local community;

� Possible provision of produce for the Canteen;

Aim

� To build a self sustaining school garden, with full student population input and day to day running;

� To provide quality produce for the school canteen;

� To sell excess produce at a market or to parents at stall once a week, with in season produce, profits to the P&C and ultimately back into the school;

� To provide pleasurable food education for students. We have a chance to positively influence children’s food choices in ways that have not been tried before;

� To provide student education on a wide range of topics with full interaction at all ages.

Aquaponics: the basics

What is it?A mini Biosphere: The fish supply nutrients for the vegetables; the vegetables clean the fish water for return to the fish tanks. It is the combination of Aquaculture (growing fish in tanks) and Hydroponics (Growing vegetables in nutrient filled water). Combining the two helps cancel out the negative aspects of each. In fact it not only cancels out the negative aspect of each method, but creates a mini Biosphere. An Aquaponic system creates a complex ecosystem that actually increase the level of production compared to other methods.

What are Aquaponics advantages? � Vegetable production up to 30 times in the same land area as a regular farm;� Water use of only 1% of a regular farm;� Fish production in addition to vegetables;� Scaleable: Home & school-sized to large commercial systems can be built and run economically;

Aquaponics Technology is Simple and Easy � Low-tech and easy to build;� Biofilter technology used is low-cost;� Mini Biosphere: the fish supply nutrients for the vegetables; the vegetables clean the fish water for return to the

fish tanks;� Only system inputs are fish feed, seeds, and makeup water for evaporation;� Balanced and stable; runs for years without water exchanges or cleaning;

Fish Tank with no herbicides� Only organic methods used for pest control

Background…

The cycle• It’s a simple cycle – fish live in water, and excrete ammonia,

pump this into beds containing vegetables/fruit, good bacteria convert this to nitrites then nitrates in which plants love and flourish, the beds then return the oxygen rich water back to thefish tank.

• There are three essential components to an aquaponicsystem, Fish, bacteria & Plants.

• It’s a very simple natural process that happens all around us in nature. The bacteria are naturally found everywhere, in streams, lakes, ponds, dams, and aquariums; they are found in the air, and will populate anywhere there is water and biological activity, like organic matter breaking down in water giving off ammonia.

Current Situation• Dwindling native fish stocks, unsustainable farming practices and severe water shortages are bringing

about a change in many primary production areas. Lack of education in healthy eating;

• We need to think outside the square when it comes to addressing these problems.

What is the link to the National

curriculum ? Phases 1, 2 & 3

(Sourced from the Australian Curriculum assessment & reporting authority)

We can address many items on the national Curriculum in all 3 phases.

Phase 1 - Maths & Science

� Skills and processes for progression in mathematics; �

� Numbers, statistics, probability, measurement and geometry; �� Proficiencies of understanding, fluency, reasoning and problem solving, eg. bernouli’s

principle;�

� Science understanding, science inquiry skills; and science as a human endeavour ; �� Science engages students in meaningful ways and prepares students to use science for

life so that they can live in a scientifically and technologically advanced society; �� Provides specific learning leading to senior secondary science as well as science and

engineering courses at university or technical and vocational education and training. �

Phase 2 – Geography, & Arts in nature

� The Man-land relationship �;

� Getting out from behind a desk (practical work) �

� Drawing leaves, flowers, gardens; �

Phase 3 - Design and Technology (outdoors) Health and Physical Education, Economics & Business.

� Design systems, students would be designing something practical; �

� Health Education �

� Running a business �

What can we do now (2010)

How will we fund the garden?• Initially from P&C Funds• External funding ?• Token Student fee of $5 or parents time ?• Lotteries Commission ?• How will we fund ongoing costs ?• Apply for a grant in 2011 (for a kitchen)

Start building now !• By starting the build of a garden now, the

school to be in a strong position to obtain funding in 2011 for $66,000 towards a covered outdoor building with simple kitchens.

• This will provide initial benefits to today’s children and future generations.

Disabled resources

• The Govt. has funding available to provide a garden for disabled students, we can provide more than just a flower garden.

• The system is at wheelchair height on a platform similar to these photos anyone can access the growbeds to plant, harvest & interact in ways never seen before.

• By building a platform between the growbedsand up to the Fish tank we can provide wheelchair access using a ramp,

• Rather than create a specific garden, we can modify our setup to cater for special needs, providing more for all students to share.

School Curriculum

Home Economics• Healthy schools – preparing organic food from the aquaponics• system look into nutritional information various foods. • Advantages & demand for organic foods, • Explore various was of preparing the produce from the system;

Maths & Business• Explore selling and the market (get the students involved);• Monitor, record and chart the running costs of an established system - compare this to the market value of the produce

harvested from the system – use this to analyse wether the system is running at a profit or at a loss;• Calculate the volume of tanks & surface area;• Calculate the cost to build an averaged sized system, stocking costs, the projected market value of produced harvested

– use all this data to calculate how long it would take to break even and run at a profit.

Science:• The Nitrogen Cycle: This can be done in several grades;• What is pH ?: focusing on ph – what is the lin to environmental conditions;• Plants: Propagation of plants - both through seed and vegetative reproduction, The life cycle of plants can easily

educated to students, and visibly monitored in an Aquaponics system;• Seeds can be planted and records kept regarding growth rate;• Lifecycle of a yabbie;• Flow Diagrams - Aquaponics system flow diagrams;• Adaptations Adaptations plants have for living in water and on dry land –including reproductive mechanisms;• Research a freshwater species and create a poster depicting all the facts, must include origin, latin name, lifecycle,

points of keeping the species, natural habitat etc;• Design and build a smaller, portable system – cold be used as an item to sell at a school market;• Create a siphon, find out how to make a machine without any moving parts.

Westfield Park Primary School

The students at Westfield Park Primary School in WA celebrated with a piscatorial feast when they harvested their first yield of trout from their aquaponic grow system. Over ninety students from Years 3 to 7 cooked fillets and whole trout on the barbeque and prepared salads and vegetables dishes with produce harvested from the garden.

“We were able to feed ninety students plus staff and volunteers with our own fish and fresh garden produce” explained Mike Burns, the school’s Program Coordinator, “All we needed to buy in was one onion, a bulb of garlic and a capsicum.”

The potato harvest proved particularly rewarding, with students digging up kilos and kilos of creamy Ruby Lou potatoes. “It was like digging for buried treasure”enthused a student.

The school is looking forward to their kitchen being ready for weekly classes in the first term of the new year. The kitchen overlooks both the aquaponic grow beds and the conventional vegie patches – with cabinets and bench tops built by students at Swan TAFE. Moving forward, the garden will be expanded further, and students are looking forward to harvesting fruit from their citrus grove and pressing their own olive oil. The aquaponic tank has now been restocked with barramundi and silver perch.
