How to Start a STEM & Sustainability Project at Your School (Without Overloading Teachers)
What if your students could learn science, maths, technology and sustainability through one project they can actually see growing?
Imagine students measuring how much water their vegetables use, testing soil conditions, monitoring plant growth or discovering how fish, bacteria and plants work together in an aquaponics system.
Instead of simply reading about sustainability, they're actively investigating it.
And the best part? You don't need a huge budget, a dedicated agriculture teacher or an entire new subject to get started.
For Australian schools looking to introduce more practical STEM and sustainability education in 2027, a school garden, hydroponic system or aquaponics project can be a surprisingly versatile place to begin.
At Urban Green Farms, we help schools turn these ideas into practical growing projects, supported by learning resources, free online courses and equipment designed for hands-on education.
Here's how to get started without making it another overwhelming job for teachers.
The Problem With Many School Garden Projects
Most schools don't struggle to find enthusiastic students....the challenge is turning that enthusiasm into a project that lasts.
A garden gets installed. Students love it. Teachers are excited.
Then the timetable gets busy, school holidays arrive, plants need watering and the project becomes one more responsibility for someone to manage.
It's a familiar problem.
But the answer isn't necessarily to abandon the idea or purchase a larger system.
The answer is to design the learning program and maintenance plan before choosing the equipment.
A successful STEM sustainability project needs three things:
A clear learning purpose.
A growing system suited to the school.
A realistic plan for ongoing care.
Get those foundations right, and even a relatively small growing project can become a valuable teaching resource.
Start With One Question, Not a Whole Garden
One of the easiest ways to introduce STEM sustainability education is to give students a real problem to investigate.
For example:
Can we grow vegetables using less water?
From that single question, students can explore plant biology, soil moisture, irrigation design, water measurement, data collection and sustainable food production.
Or you could ask:
Can plants grow without soil?
Suddenly, students are exploring hydroponics, nutrient solutions, root systems, water quality and controlled growing environments.
Another possibility:
What happens to food waste when we compost it?
This introduces decomposition, microorganisms, soil biology, nutrient cycling and the relationship between waste and food production.
Each of these questions can become a practical STEM project without requiring teachers to develop an entirely new curriculum.
Three Ways to Start STEM Sustainability at Your School
1. Soil Science & Sustainable Food Growing
Best for primary schools, garden clubs, kitchen gardens and outdoor learning spaces.
A productive school garden is one of the most accessible ways to introduce sustainable food production.
Students can investigate soil health, germination, water retention, composting, nutrient availability and the organisms living beneath their feet.
Wicking garden beds such as FoodCube are particularly interesting because their built-in water reservoirs create opportunities to explore how water moves through growing media.
Students can compare watering methods, monitor soil moisture and investigate how growing conditions affect plant development.
Project idea: Which Growing Method Uses Water More Efficiently?
Students grow the same crop in two suitable growing setups, monitor water additions and record plant growth over several weeks.
They can then graph their results, discuss the differences and propose improvements.
For schools wanting a more complete setup, our Soil Sustainability Project Kit brings together:
Three FoodCube wicking beds
Worm composting system
Soil testing equipment
Propagation kits and seeds
Happy Soils plant nutrition
Gardening accessories
It's designed to combine soil science, composting, water management and food production in one practical educational project.
2. Hydroponics & Controlled Growing
Best for STEM classrooms, secondary science, food technology and schools with limited outdoor garden space.
Hydroponics provides an opportunity to investigate a question students often find fascinating:
How can plants grow without soil?
Students can examine the role of water, dissolved nutrients, oxygen, light and environmental conditions in plant growth.
A classroom hydroponic system can support investigations into pH, electrical conductivity, nutrient management and system design.
Students can also compare growing conditions and record the effects over time.
Project idea: What Makes Lettuce Grow Best?
Students grow lettuce using a suitable hydroponic system and investigate an approved variable such as light duration, while keeping other conditions consistent.
They measure growth, collect observations and use their results to recommend better growing conditions.
This turns one growing system into a practical classroom experiment.
Urban Green Farms offers hydroponic systems ranging from compact classroom growing units to larger educational growing setups.
3. Aquaponics & Living Ecosystems
Best for established STEM programs, secondary schools and larger sustainability learning projects.
Aquaponics takes sustainable food production into a fascinating new area.
It combines fish, plants and beneficial bacteria within a recirculating water system.
Students can observe how fish waste is processed by microorganisms, how nutrients become available to plants and why maintaining water quality is essential.
It creates opportunities to investigate biology, chemistry, engineering, water conservation and ecosystem relationships.
Project idea: How Does a Living Ecosystem Maintain Balance?
Students monitor water quality and plant development over time, recording changes in pH, ammonia, nitrite and nitrate as appropriate.
They investigate how system components depend on one another and what happens when conditions change.
For schools planning a more substantial project, Urban Green Farms offers the EduGrow Sustainability Learning Bundle, combining an 1100L aquaponics system with FoodCube wicking beds, propagation supplies, soil monitoring and growing accessories.
It brings soil-based growing and aquaponics together, creating opportunities for students to compare different food production methods.
Aquaponics projects require a properly planned management program, including fish welfare, water quality monitoring, system maintenance and holiday care.
A Simple Six-Week STEM Sustainability Project for Schools
Not sure how to turn a growing system into actual classroom lessons?
Here's a straightforward six-week example that can be adapted to primary or secondary students.
Week | Student activity | STEM connection |
1. Investigate | Choose a food-growing or environmental problem and develop a question | Science inquiry and problem-solving |
2. Design | Plan the growing setup, identify materials and begin planting | Engineering and Design Technologies |
3. Measure | Record moisture, pH, temperature, light or plant growth | Science and Mathematics |
4. Compare | Collect observations and investigate differences between growing conditions | Experimentation and data analysis |
5. Improve | Review results and recommend changes to the system | Critical thinking and design improvement |
6. Share | Present findings, graphs and recommendations to the class or school | Communication and evidence-based reasoning |
By the end of the project, students will have worked through a real investigation rather than simply completing an activity.
They may have seedlings, growing vegetables, a functioning system or valuable experimental results to demonstrate.
And because the equipment remains at the school, the same system can support future classes and investigations.
Does This Fit the Australian Curriculum?
Yes, practical STEM sustainability projects can support several areas of the Australian Curriculum when activities are planned against the relevant year-level content descriptions.
Sustainability is a recognised cross-curriculum priority in Australian Curriculum Version 9.0.
Growing projects provide meaningful contexts for exploring this priority through Science, Mathematics and Design and Technologies.
For example:
Science: Students investigate plant growth, water quality, biological systems, microorganisms and environmental changes.
Technology: Students use sensors, pumps, timers, irrigation equipment and monitoring tools.
Engineering: Students plan growing structures, water movement, filtration, drainage and system improvements.
Mathematics: Students measure water use, graph plant growth, calculate changes and compare results.
Sustainability: Students investigate food systems, resource efficiency, nutrient cycling and waste management.
The key is selecting learning outcomes appropriate to your students and planning meaningful investigations around them.
Urban Green Farms' teacher resources can help you explore practical ways to connect these topics to your classroom.
You Don't Have to Create All the Learning Resources Yourself
One of the biggest barriers to introducing something new in a school is finding time to prepare the lessons.
That's why Urban Green Farms has developed free online growing courses and a dedicated Teachers Portal.
Our online courses cover three important areas of sustainable food production:
Hydroponics: Learn how plants grow using water, nutrients and controlled growing environments.
Aquaponics: Explore the relationship between fish, plants, bacteria and recirculating water.
Soil: Discover the living world beneath our feet, soil biology and the foundations of healthy soil.
The courses include Juniors and Masterclass pathways, allowing schools to select content suited to different ages and levels of understanding.
Teachers can use the resources to introduce concepts before students begin working with physical growing systems.
Visit the Urban Green Farms Teachers Portal
Our Teachers Portal provides access to additional resources, including lesson materials, school catalogue information, installation guides, aquaponics maintenance resources and grant planning support.
That means schools can access more than equipment when introducing a new growing project.
What Should Your School Consider Before Purchasing?
A little planning will make a big difference to the success of your project.
Start by considering your students' year levels, curriculum goals and available space.
Then identify a staff member who will coordinate the project and establish how routine maintenance will be managed.
For growing systems, the practical details matter: access to water and power, sunlight, ventilation, safe student access, cleaning and storage.
Don't forget school holidays.
This is particularly important for aquaponics systems containing fish, which require ongoing animal care and water management.
Wicking beds, hydroponics and aquaponics each have different maintenance requirements, so the best system is the one your school can realistically operate.
What If Our School Doesn't Have the Budget Yet?
Not every school needs to purchase a complete sustainability learning hub immediately.
You might begin with a classroom propagation project, introduce soil monitoring or install a few growing beds.
Once students and staff are comfortable, the project can be expanded.
Schools can also explore relevant grants, community partnerships, parent fundraising and school sustainability funding programs.
Urban Green Farms can help schools prepare project descriptions, equipment recommendations and supporting information for funding applications.
Funding eligibility and deadlines vary by program, so always check the current grant requirements before applying.
Planning a STEM & Sustainability Project for 2027?
Term 4 is a useful time to begin planning for the following school year.
It gives teachers and school leaders an opportunity to define learning goals, review budgets, identify suitable locations and work out what equipment will be required.
Schools can start with a simple soil science activity or develop a larger program combining aquaponics, hydroponics, composting and food gardens.
The important thing is to start with a project your students can understand, investigate and build upon.
