Children will go on a nature walk and note their surroundings, then write a letter to nature, in this two-page writing and mindfulness worksheet. Page 1 includes space for learners to record their observations about the plants, animals, sounds, and weather they observe. Page 2 offers five sentence starters for writers as they compose their letter. Designed for third and fourth graders, this thoughtful worksheet can be used for every season. Use it in the fall as a meaningful addition to a Thanksgiving lesson on gratitude.
