Phases of the Moon helps students gain a better understanding of the motions of Earth and the Moon in relation to the Sun, which result in the phases of the Moon we observe on Earth.
FOSS PLANETARY SCIENCE COURSE INVESTIGATION 9: PHASES OF THE MOON Courtesy of UCO/Lick Observatory GOAL Phases of the Moon helps students gain a better understanding of the motions of Earth and the Moon in relation to the Sun, which result in the phases of the Moon we observe on Earth. OBJECTIVES SCIENCE CONTENT • Identify and name the phases of the Moon. CONDUCTING INVESTIGATIONS • Use models of the Sun, Moon, and Earth to explain the mechanics of Moon phases and eclipses. • Sequence representations of the phases of the Moon. BUILDING EXPLANATIONS • Explain the roles of rotation and revolution of Earth and the Moon in the presentation of phases, and when and where they are observed in the heavens. • Predict relative positions of the Sun, Earth, and Moon when shown a representation of a Moon phase. • Describe how the Moon revolves around Earth once a month, resulting in the Moon rising about 50 minutes later each day.

After writing • Identify and name Moon phases. Quick Write down their ideas about Moon • Explain the roles of rotation and Explain phases phases, students update and study revolution of Earth and the their Moon Logs to determine the Moon in the presentation of sequence of changes. Phase phases. Informal Notes vocabulary is developed, followed • Describe how the Moon revolves by study of moonrise in an effort to around Earth once a month, understand the reasons for phases. resulting in the Moon rising 50 minutes later each day. PART 2 What Causes Moon Phases? • Use models of the Sun, Moon, Teacher Observation Students use small polystyrene balls and Earth to explain the Model phases and a light source to simulate Moon mechanics of Moon phases and phases. They incorporate their small eclipses. Student Journal globes into the system to obtain • Explain the roles of rotation and Explain phases another point of view on Moon- revolution of Earth and the phase mechanics. Finally they use a Moon in the presentation of light source and large Moon globe to phases, and when and where study Sun/Earth/Moon they are observed in the relationships, including eclipses. heavens. PART 3 Thinking about Moon Phases. • Explain the roles of rotation and Informal Notes Students complete a Moon-phase revolution of Earth and the sheet that displays images of phases Moon in the presentation of Student Sheet from two points of view phases. Looking at the Moon from Earth simultaneously. To help them visualize the points of view, students assemble an Earth/Moon model using their globes and polystyrene balls. PART 4 Moon-Phase Puzzles. Students • Sequence representations of the Teacher Observation sequence nine Moon-phase images to phases of the Moon. Sequence phase images show an accurate progression • Predict relative positions of the through a month.
