By year 7 bilingual students created awareness posters about recycling and saving water and energy. The posters provided tips such as taking showers instead of baths to save water, turning off taps when not in use, using eco-friendly products like recycled paper and soap, only using necessary water when washing hands, turning off electrical appliances when not in use, using energy saving lightbulbs, and recycling materials to help the environment. The document emphasizes that small actions can help save the planet.
