Students from International Community School, Accra, have developed a range of technology-driven solutions, including motion-sensor bins and anti-bullying apps, at a school innovation exhibition aimed at addressing everyday challenges.
The project was showcased at the inaugural TechVation Exhibition, held on March 19, bringing together learners from preschool to high school to design practical solutions across areas such as engineering, coding, fashion, and environmental sustainability.
Organisers say the initiative encourages students to identify real-world problems and apply creativity and technical skills to address them. Among the projects on display was “IntelliBean,” a sensor-activated waste bin that opens automatically to reduce contact with germs. It also uses colour indicators to show when it is full, in an effort to improve waste management and hygiene.
Another group focused on plastic waste, developing a system to convert discarded materials into filament for 3D printing.
“We realised plastic waste is increasing, so we thought, why not recycle it into filament for 3D printing useful items?” one student said.
Several innovations were designed to improve daily school life. These included a biometric locker system to prevent lost keys and a digital platform that allows targeted announcements to be sent to specific areas at scheduled times. Students also created a QR code-based counselling system, which enables users to access support depending on their emotional state.
“If you’re feeling afraid, you can scan the QR code and get help,” a participant explained.
Other projects included a digital library and attendance system, a device tracking application, and tools aimed at improving student safety, including anti-bullying platforms. Not all of the ideas were digital. One group designed ergonomic chairs to address discomfort during long lessons.
“When children sit on hard chairs for long, they get distracted, so we created more comfortable seating,” a student said.
Parents and visitors who attended the exhibition said they were impressed by both the quality of the projects and the confidence with which students presented them.
“Some of the projects, I couldn’t believe children actually did them,” one parent said.
Organisers say the exhibition reflects a growing emphasis on practical, skills-based learning, with plans to make TechVation an annual event and potentially integrate some of the student projects into school systems.
