This document introduces the concept of time zones, noting that because the Earth spins and revolves around the sun, one side is always in light while the other is in darkness.

The document outlines tasks for students to learn about time zones by reading a passage and answering questions, filling in blanks of a reading comprehension, and reviewing a website to answer additional time zone questions.
