The Moon Lesson
Teach students about the moon with this printable space science lesson. Explains that the moon is Earth’s only natural satellite and covers its key facts: distance from Earth, size compared to Earth, and its 28-day orbit. Explains why the moon appears to change shape — the phases we see depend on how much of the sunlit side faces Earth at any given time. Covers the lunar phases from new moon through crescent, quarter, gibbous, and full moon. Includes comprehension questions and answer key.

Lesson Overview
The Moon’s Orbit, Phases, and the Earth-Moon System
The lesson explains that the moon does not produce its own light but reflects sunlight, and that as it orbits Earth we see different fractions of its lit side. Students learn the names of the eight main lunar phases and how to recognize whether the moon is waxing (growing) or waning (shrinking) in the night sky.
The four-page lesson pairs a reading passage with comprehension questions. Students learn about the moon’s surface features, how its gravity causes tides, and why the same side of the moon always faces Earth. A complete answer key is included.
How to Use This Lesson
1. Read the lesson passage together or have students read silently (pages 1–2). Ask students to explain in their own words why the moon’s shape appears to change.
2. Discuss the moon’s phases. Have students draw and label the eight lunar phases in order and identify which are waxing and which are waning.
3. Assign the comprehension questions (page 3) independently. Review answers using the key on page 4.
