- Liquid Trees: A Biotechnological Solution to Air Pollution
Grade Level: High School
Linked SDGs: Goal 11 (Sustainable Cities and Communities), Goal 13 (Climate Action)
Innovative Idea:
The Liquid Tree project represents a pioneering approach to combating urban air pollution. This innovative system consists of a 600-liter water tank serving as a habitat for microalgae. Using photosynthesis, the microalgae absorb carbon dioxide (CO2) from the surrounding air and release oxygen, mimicking the natural function of traditional trees in urban areas with limited green spaces.
Challenges Overcome:
Designing a system to efficiently manage the gas exchange process was a key challenge. Students incorporated outlets for CO2 and oxygen, ensuring optimal functionality. Balancing sustainability with scalability also required advanced research and meticulous engineering.
Impact:
The Liquid Tree project provides a scalable, eco-friendly solution for air purification in cities. By reducing CO2 levels and increasing oxygen output, it offers a novel approach to mitigating the effects of climate change and enhancing air quality in urban environments.
- Two-in-One STREAM™ Water and Energy System
Grade Level: High School
Linked SDGs: Goal 6 (Clean Water and Sanitation), Goal 7 (Affordable and Clean Energy), Goal 13 (Climate Action)
Innovative Idea:
The STREAM™ Water and Energy System addresses two critical global issues—water scarcity and sustainable energy. This dual-purpose innovation filters contaminated water into sanitary water while simultaneously generating renewable, carbon-free energy. The system employs advanced water filters layered within a container, directing water through a turbine generator to produce energy, and finally completing the purification process in a sealed PVC pipe.
Challenges Overcome:
Integrating water filtration and energy generation posed a significant challenge. Students had to refine the design to ensure that water flow mechanics worked seamlessly, balancing efficiency with environmental impact.
Impact:
This project promotes hygiene, sanitation, and sustainability by delivering clean water and renewable energy. It serves as a model for addressing water and energy challenges in resource-scarce regions, contributing to healthier and more sustainable communities.
- Smart Bridge: Adaptive Infrastructure for Flood Management
Grade Level: Middle School
Linked SDGs: Goal 9 (Industry, Innovation, and Infrastructure), Goal 11 (Sustainable Cities and Communities), Goal 14 (Life Below Water)
Innovative Idea:
The Smart Bridge project showcases how technology can be used to create adaptive infrastructure. By integrating sensors and microcontrollers, the bridge monitors water levels and adjusts its height automatically during flooding, ensuring safe passage for vehicles. This design reduces the need for tall, permanent bridges, which often disrupt natural ecosystems.
Challenges Overcome:
Developing a reliable, automated system required extensive testing and fine-tuning of the sensors and microcontrollers. Students also worked to minimize the environmental impact of their design while maintaining structural integrity and efficiency.
Impact:
This project demonstrates how sustainable infrastructure can address urban resilience challenges while preserving ecosystems. By reducing flooding risks and maintaining accessibility, the Smart Bridge exemplifies innovation in infrastructure that balances human needs with environmental stewardship.
- Medical Diagnostic Device: Empowering Early Innovation in Health Technology
Grade Level: Elementary
Linked SDGs: Goal 3 (Good Health and Well-being), Goal 9 (Industry, Innovation, and Infrastructure)
Innovative Idea:
The Medical Diagnostic Device is a breakthrough project by AHIS elementary students, aimed at improving healthcare accessibility and accuracy. The device integrates advanced sensors and an intuitive interface to provide precise diagnostics, making it particularly beneficial for underserved communities.
Challenges Overcome:
Simplifying complex medical concepts for young students while maintaining functionality required significant guidance and collaboration. Despite their age, the team successfully conceptualized and delivered a prototype that meets practical healthcare needs.
Impact:
The project highlights how even the youngest innovators can contribute to addressing global health challenges. It underscores the importance of health equity and accessibility, inspiring future advancements in medical technology.
About the School:
At Al Hekma International School (AHIS), innovation and sustainability are at the heart of our educational mission. Through our STREAM (Science, Technology, Research, Engineering, Arts, and Mathematics) program, we empower students to engage in transdisciplinary approaches to problem-solving, integrating knowledge and skills from multiple fields to address complex real-world challenges.
These projects are not merely academic exercises but are aligned with the United Nations Sustainable Development Goals (UN SDGs), focusing on creating solutions that address local challenges in Bahrain while contributing to global advancements. From tackling air pollution and ensuring clean water access to developing adaptive infrastructure and enhancing health diagnostics, AHIS students exemplify the transformative potential of education. Here, we proudly showcase four exemplary STREAM projects that highlight their creativity, innovation, and commitment to sustainability.
