Section 1
Earth Rotates to Create Day and Night
Earth turns on its axis every 24 hours, making stars appear to move across the night sky. This rotation creates the illusion that the Sun moves from east to west daily.
In this Grade 6 Earth Science lesson from Chapter 19: Exploring Space, students learn how the universe is arranged into structures such as planets, solar systems, and galaxies, and how gravity groups objects in space together. Students also explore how stars form patterns called constellations in the sky and how Earth's rotation affects the apparent motion of the Sun and the positions of space objects as seen from Earth.
Section 1
Earth Rotates to Create Day and Night
Earth turns on its axis every 24 hours, making stars appear to move across the night sky. This rotation creates the illusion that the Sun moves from east to west daily.
Section 2
Gravity Organizes Space Objects Into Structures
The universe contains organized structures including planets, solar systems, and galaxies. These aren't random - gravity pulls objects together, creating patterns from the smallest planets to entire galaxy clusters.
Section 3
Stars Form Patterns Called Constellations
Stars appear grouped in patterns called constellations when viewed from Earth. These stars aren't actually close to each other in space but help astronomers divide the sky into 88 named areas.
Section 4
Planets Wander Through Star Patterns
Unlike distant stars that appear fixed, planets visibly move through constellations over weeks or months. The Moon moves fastest across our sky because it's closer to Earth than other space objects.
