Sustainability
As an international educational institution, we are making increased efforts to integrate sustainable thinking and actions into everyday school life.
Promoting sustainability and awareness for our natural environment is part of GISB’s mission. Teachers in all grades integrate environmental science and sustainability topics into their curriculum, which range from learning about pollinators in preschool to plastic chemistry and consumption in high school. Other topics include reducing ecological footprints, adapting to climate change, and eco-friendly traveling.
In May 2020, GISB received the 2020 Project Green Schools Green Difference Award, which honors outstanding energy, environmental & STEAM education efforts led in schools and communities.
Climate Change Week
Climate Change Week is an exciting time at GISB, filled with a variety of hands-on activities designed to raise awareness and inspire action. From building bee houses and crafting seed bombs to designing custom Earth Day tote bags, students across all grade levels actively participate in events that highlight the importance of sustainability.
In 2022, for example, our youngest students immersed themselves in a wide range of activities, including learning about animals and trees, creating art projects, reading a book about Greta Thunberg, and embarking on a cleanup mission at a nearby park.
Our elementary school team prepared engaging, hands-on projects, such as ‘Upcycling’ workshops where students transformed everyday trash into creative and useful objects, while learning about the importance of recycling and reusing materials.
Middle and high school students explored various aspects of climate change and sustainability through interdisciplinary projects and experiments, coordinated by their teachers. These activities provided them with a deeper understanding of the environmental challenges we face and empowered them to take meaningful action.
Environmental Museum
In March, GISB dedicates an entire month to environmental education, where students across all grade levels immerse themselves in topics like climate change, sustainability, and the wonders of nature. This enriching experience culminates in our highly anticipated annual Environmental Museum exhibition, a dynamic event that unites the entire school community in celebration of our students’ creativity and commitment to the planet.
Our Environmental Museum is more than just an exhibition; it’s a celebration of our students’ commitment to understanding and protecting the planet. Through their projects, they not only demonstrate their knowledge but also inspire others to take action for a more sustainable future.
Zero Waste Day
Zero Waste Day is a student initiative that asks all students and faculty to avoid producing garbage for a day. We produced about 6 ½ lb or 3 kg less garbage on a Zero-Waste-Day than on a regular day. The goal of the initiative is to make students more aware of the general waste and plastic problem.
Plastic Pollution Awareness
Grade 11 students explored plastics and the problems of plastic pollution in an integrated Arts and Chemistry project. In Chemistry, students produced nylon and polyurethane in the lab, and in Visual Art, students explored the problems of plastic pollution.
Drive To Plant More Trees
GISB’s grade 5 students built raised vegetable beds on campus. The vegetables are sold to the community, and the proceeds are used to buy tree seedlings. Planting trees is a simple way to soak up carbon emissions and curb the effects of climate change.
Charles River Clean Up
Environmental protection starts right where you live and learn. Our students regularly venture out to the Charles River to collect trash and clean up the parks and trails along the river.
Environmental-Friendly Purchases
If possible, the school purchases environmentally friendly products. We switched to copy paper, toilet paper, and tissues made out of recycled material and introduced compostable cutlery for events.
