6.1.1: Moon & Seasons 3 Dimensions & Progressions

Unit 1

STANDARD 6.1.1

6.1.1 Develop and use a model of the Sun-Earth-moon system to describe the cyclic patterns of lunar phases, eclipses of the sun and moon, and seasons. Examples of models could be physical, graphical, or concept. MS-ESS1-1

CONCEPTS

SKILLS

●​ Sun-Earth-Moon System ●​ Lunar Phases ●​ Eclipse of Sun/Moon ●​ Seasons

●​ Develop a model ●​ Describe patterns

LEARNING PROGRESSIONS

●​ Earth revolves around the Sun every 365 days ●​ Moon revolves around the Earth every 28 days ●​ Moon phases occur because of where the Moon is in relation to the Earth ●​ Earth Tilts on an Axis ​ ●​ Amounts of direct/indirect sunlight determine seasons VOCABULARY

●​ Northern Hemisphere ●​ Southern Hemisphere ●​ Equator ●​ Polaris

●​ Direct/Indirect Light ●​ Moon Phase ●​ Eclipse ●​ Tilt ●​ Axis ●​ Solstice

●​ Waxing ●​ Waning ●​ Gibbous ●​ Crescent ●​ Tides ●​ Equinox ●​ Cycle

●​ Poles ●​ Lunar

POSSIBLE PHENOMENA

●​ When observed from Earth over the course of a month, the moon appears to change shape. ●​ At times somewhere on Earth during the day it goes completely dark. ●​ Summer in the Southern Hemisphere is winter in the Northern Hemisphere. ●​ Snow melts on the south slope of a hill before it melts on the north slope. END OF UNIT COMPETENCY WITH LANGUAGE SUPPORTS ●​ I can explain how the tilt of the Earth’s axis and its yearly orbit around the sun produces seasons. ○​ Language Supports: ■​ verbs (ie. have, be, belong to) ■​ statements (ie. the moon rotates around the earth)
