No Prep Sub Plans: Time Zones Research + Group Project | Build a Global Clock

No Prep Sub Plans: Time Zones Research + Group Project | Build a Global Clock Guide Grades 5–8
Help students understand how the world stays connected through time zones with this engaging, real-world geography and research project!
In this collaborative middle school activity, students explore how Earth’s rotation connects to time zones, UTC/GMT, daylight saving time, and global scheduling. Working in groups, students research world cities, compare time differences, solve real-life scenarios, and create a global clock guide that explains how time changes across the world.

This lesson combines geography, Earth science, math, global awareness, and problem-solving into a highly engaging project that is easy for a substitute teacher to facilitate in a single 45–50 minute class period.

Perfect for Geography, Social Studies, STEM integration, Global Studies, or cross-curricular learning!
