Take your class outside on a walk to observe the local environment. This could include both the natural and built environment. You could ask your students to look for anything from flora and fauna to evidence of adaptations to climate change.
The focus on local helps conceptualize broader issues at a scale in which local actions can be both considered and implemented. Schoolyards and neighbourhood have a lot to offer in terms of learning opportunities – they can provide a diverse landscape to explore and expand classroom learning. Walking trips can serve many purposes (including having a positive health impact on students!)
During and after the walk, students can document their observations through photos, sketches and notes.
