This hands-on STEM project introduces students to the engineering design process, basic electronics, and the principles of automated systems. Students will explore how sensors and actuators work together to create a functional watering machine that responds to environmental conditions. The activity promotes problem-solving, critical thinking, and an understanding of sustainable technology. Key learning outcomes include the concept of input and output devices, simple circuit construction, and the application of computational thinking to real-world challenges such as plant care and water conservation.
Designed for primary and lower secondary students, this product is ideal for Years 3–8. It aligns with classroom instruction in Digital Technologies, Science, and Design and Technologies. The project is suitable for STEM clubs, makerspace activities, and cross-curricular units on sustainability, biology, and systems thinking.
This product directly supports the Australian Curriculum: Digital Technologies (Years 3–8) by teaching students to define simple problems, design algorithms, and implement digital solutions. It addresses Science (Years 3–6) outcomes related to biological sciences (plant growth needs) and physical sciences (electric circuits). The project also aligns with the STEM F-10 framework by integrating science inquiry skills, engineering design, and mathematical reasoning. Specific content descriptors include ACTDIK007 (recognition of digital systems), ACTDIP010 (designing solutions), and ACSSU097 (electrical energy).
This kit uses a block-based coding environment compatible with Scratch or MakeCode, making it accessible for beginners. No prior coding experience is required. Step-by-step guides are provided to help students program the watering machine to activate based on soil moisture levels or timers. For advanced users, the platform supports text-based coding in Python.
Each kit contains: 1 microcontroller board (compatible with common education platforms), 1 soil moisture sensor module, 1 mini water pump, 1 relay module, connecting wires, a USB power cable, a water reservoir tube set, and a project baseboard. All electronic components are pre-tested and classroom-safe. The box also includes a printed instruction booklet with wiring diagrams, coding examples, and extension activity ideas.
Each student or pair requires a computer or tablet with internet access for coding. A USB power source (e.g., laptop port or USB wall adapter) is needed to run the pump. The project uses low-voltage components and is safe for classroom use. Minimal additional materials are required: a small cup of water and a potted plant or soil sample. Teachers should allow approximately 60–90 minutes for initial assembly, coding, and testing. No soldering or specialist tools are needed.
