Earth-Moon-Sun relationships and lunar phases are the focus of this Grade 6 Science worksheet on Earth's place in the universe. Students examine how the positions of the Sun, Earth, and Moon create the repeating pattern of lunar phases and how alignment produces solar and lunar eclipses.

Build astronomy concepts through reading and application. A focused reading passage introduces sunlight, the Moon's orbit, the primary phases, eclipse alignment, and the predictable patterns of the Earth-Moon-Sun system. Students then apply those ideas through multiple-choice questions, true-or-false statements, short-answer responses, a labeled diagram, a categorization task, and a short note.

What Students Practice

Students explain why the Moon appears to change shape as different portions of its sunlit half are visible from Earth. They identify the positions that produce a new moon and full moon, recognize what observers see during the quarter phases, and sequence the primary lunar phases: new moon, first quarter, full moon, and third quarter.

The worksheet also develops solar eclipse and lunar eclipse vocabulary through alignment-based reasoning. Students distinguish a solar eclipse, when the Moon blocks sunlight from reaching part of Earth, from a lunar eclipse, when Earth blocks sunlight from reaching the Moon. They connect these observations to the predictable motion of the Earth-Moon-Sun system.

Included for Classroom Use

• ✔️ Student worksheet covering lunar phases, eclipse alignment, and predictable sky patterns
• ✔️ Student Notes lines at the bottom of the worksheet
• ✔️ Answer Key PDF with a Teacher Guide
• ✔️ Teacher Guide with Learning Objectives, Teaching Tips, Discussion Questions, and Common Mistakes

Flexible Science Practice

Use this resource to introduce or reinforce lunar phases and eclipses, provide independent practice after instruction, check student understanding of Earth-Moon-Sun alignment, or support classroom discussion about predictable astronomical patterns. The combination of explanatory reading, selected-response questions, written explanations, and visual tasks gives students several ways to demonstrate their understanding of the lesson concepts.

With its clear focus on lunar phase patterns, eclipse alignment, and the relationship between the Sun, Earth, and Moon, this resource gives Grade 6 learners structured practice connecting observations in the sky to the positions and motions of objects in space.
