Lesson Overview
The Solar System, Constellations, and Moon Phases
The lesson opens with the sun — its size compared to Earth, its distance, and its role as the source of light and heat for our solar system. Students learn the names and order of the planets and what makes each one unique at an introductory level.
The six-page lesson then covers stars and constellations, explaining how ancient peoples used star patterns for navigation and timekeeping. It closes with the moon’s 28-day orbit and the four main phases. Comprehension questions and a complete answer key are included.
How to Use This Lesson
1. Read the lesson passage together or have students read silently (pages 1–3). Ask students to name the planets in order from the sun.
2. Discuss moon phases. Have students draw and label the four main phases (new moon, half moon, gibbous, full moon) and explain why they occur.
3. Assign the comprehension questions (pages 4–5) independently. Review answers using the key on page 6.
