Problem statement and objective: Teaching difficult concepts like alternative energy sources, electricity, and microbes without expensive laboratory equipment is very challenging in the primary school science subject. To further advance the benefit of this project, in which we have proven the experiment of the VIBES 'mood ring,' this initiative aims to turn the project into a modular consumer kit and an affordable, hands-on teaching tool.

Methodology: The project is based on the plant microbial fuel cell (PMFC) technology. It uses wet soil as an electrolyte to move energy between two metals (copper and a galvanized nail), which are the anode and cathode, which is then measured by a digital multimeter in terms of their voltage. We made a standard hardware kit and a full classroom module to turn this into a learning activity instead of just an experiment. This module fits perfectly with the Kurikulum Standard Sekolah Rendah (KSSR) and Dual Language Programme (DLP) frameworks used in Malaysian schools. It focuses on the Year 5 unit of study about energy and electricity.

Results and new approach: The VIBES kit's main approach is to use microbes as the sensors for the plant's health to create a highly interactive learning environment. In controlled experiments, students used the kit to detect voltage changes, showing that "healthy," moist plants produce stronger electrical signals than wilted plants. This makes learning about bio-electricity more fun and interactive than just reading about it in a textbook. Students then use our modules to fulfill the class syllabus for year 5 KSSR and DLP.

Conclusion and entrepreneurial impact: The VIBES kit has significant economic potential, in addition to being a useful scientific module that fits with KSSR. This kit can be used in two ways: as a STEM teaching tool in schools and as a useful, real-time environmental monitor for home gardens and small farms to help them keep track of their water use. This project meets both the need for long-term, practical agricultural solutions and the goal of making scientific education more affordable and accessible.

UN SDG alignment:

1. SDG 4: Quality Education (Target 4.7). The project uses Plant Microbial Fuel Cell (PMFC) technology as an interactive teaching tool to enable bioelectricity to be physically studied and become a real STEM learning experience. This module may be quickly spread to elementary schools by replacing expensive lab equipment with cheap materials. This will make scientific teaching more consistent and of higher quality.

2. SDG 6: Clean Water and Sanitation (Target 6.4). This VIBES mood ring acts as a sensor, alerting the owner of plants to the exact time plants need watering. This enables the homeowners or small farmers to manage water resources efficiently. Hence, conserving water for everyday agricultural use. 

3. SDG 12: Responsible Consumption and Production (Target 12.2). The project innovatively utilizes living organisms as zero-cost sensors, so we don’t need expensive equipment for monitoring. Eliminating the reliance on expensive environmental monitoring equipment. When this technology is widely used, it encourages healthy farming methods by making the best use of natural resources and stopping overwatering.
