This document provides information about a webquest on studying change through different sciences. It outlines tasks for students to research how change is studied by entomologists, meteorologists, geologists, and astronomers. For astronomy, it specifically discusses how the moon appears to change shape from Earth, but does not actually change shape. It then provides resources for students to learn about the phases of the moon, including a diagram explaining how sunlight hits different parts of the moon as it orbits Earth.
