Learning about materials and their properties helps us understand how things around us are made and why certain materials are used for specific purposes, like why glass is used for windows or plastic for bottles. By studying environmental sustainability, we learn how to use materials wisely without harming nature, like recycling or choosing biodegradable options. This knowledge helps us make smart decisions today, like reducing waste and protecting resources. In the future, you can use what you’ve learned to create better, eco-friendly products and help build a world that is safer and healthier for everyone!
