I usually teach this during the week of earth day. I have my students to watch a video on brainpopjunior.com about recycling and the importance of it. This is the link for the video:https://youtu.be/-ZFInnwmmis?si=prZAgizdeXpTaqJH. I have also had students to plant beans to see how they grow and we talk about the importance of plants and why they are also important to animals.

Those are great approaches to teaching environmental sustainability! In addition to watching videos and planting beans, you might consider incorporating interactive activities like creating a classroom recycling program or organizing a waste-free lunch day. Hands-on projects, such as building bird feeders from recycled materials or starting a small garden, can further engage students and help them understand their role in environmental conservation. Field trips to local recycling centers or nature reserves can also provide real-world context and make the concept more tangible.
