K-12 Teachers in US - Backpack Weight & Daily Essentials - By Aug 1

Are kids bringing too much to school these days? How heavy is too heavy for a backpack? And what do students actually need each day? 🎒 📚 ✏️ I'm writing about back-to-school and am looking for K-12 teachers across the U.S. to interview before August 1. What do you wish parents knew about preparing for school? Would love to hear from you or someone you know!
