At Grenfell Public School, Stage 2 students are getting a taste of the future of farming with their weekly science lessons led by Mrs 'Professor' Makin. This term’s unit, 'Living World,' has introduced these young scientists to the cutting-edge world of aeroponics—a method of growing plants without soil, using nutrient-rich mist instead.
The class is diving into this hands-on experience with the Stem.T4L Aeroponics Kits, an innovative tool that allows students to cultivate a variety of vegetables and herbs in a controlled environment. From broccoli and cauliflower to carrots, capsicum, and various herbs, the students are not just learning about plants—they’re watching them grow from seeds to full-grown vegetables right outside classroom.
Aeroponics differs from traditional horticulture by using a system where water trickles over the roots of up to 60 plants. This setup maximizes oxygen absorption and accelerates growth rates.
The two modular grow towers outside the classroom allow the students to observe the plant's needs and the differences between aeroponics and conventional growing methods.
Students began their journey by planting seeds in Airgarden grow plugs made from coconut fibre, eliminating the need for soil. Over the course of 1-2 weeks, they watched as their seeds sprouted and developed roots. The real excitement came when the Airgardens were assembled. Following step-by-step instructions, students learned about the various components including the water pump, hoses, and tower system. They filled the towers with water and placed their seedlings into the Airgarden, eagerly anticipating the next stages.
The towers are set to a timer that activates every 15 minutes, ensuring that water drips over the seedlings to nourish them. Students also engage in critical scientific practices such as monitoring the pH levels of the water, which is crucial for healthy plant growth.
Through testing and adjusting the pH levels, they gain valuable insights into the needs of plants and the importance of maintaining the right conditions for optimal growth.
“The kids are thrilled to see their plants growing and are really invested in the whole process,” Mrs Makin commented.
“This project not only teaches them about plant biology but also emphasises sustainability and the potential of future farming technologies.”
Although harvest time is still a while away, the students are excited to reap the fruits of their labour and use their vegetables and herbs in our school kitchen.
The aeroponics project at Grenfell Public School extends beyond a science lesson – it provides a glimpse into the future of agriculture through learning and discovery.
