Scale in the Solar System SIXTH GRADE SCIENCE STANDARDS: STANDARD FOUR Students will understand the scale of size, distance between objects, movement, and apparent motion (due to Earth’s rotation) of objects in the universe and how cultures have understood, related to and used these objects in the night sky. OBJECTIVE 1 Compare the size and distance of objects within the systems in the universe. ACTIVITY DESCRIPTIONS: Activity One: Activate Prior Knowledge: “Powers of Ten Video” and Explore the sizes of various objects in the solar system Activity Two: 2D Comparison and Investigation of the size of the sun, earth and moon Activity Three: 3D Comparison and Investigation of the size and volume of Earth and the Moon Activity Four: Construct a 2D Scale Model of the Solar System: There are two versions: easy and advanced. Activity Five: Examine the Scale of Solar System on a Meter Stick Activity Six: Construct an Outdoor Scale Model of the Solar System: 3 Different Versions: Meters, Paces, or Toilet Paper Squares Activity Seven: Investigate the Apparent Sizes of Objects in the Solar System Activity Eight: Investigate the Expanding Universe using a Balloon Activity Nine: Use Math to Scale down the Solar System by diameter and distance using astronomical units THE IMPORTANT POINTS The Solar System is an enormous empty space. Even our closest neighbors in space are very large distances away. Space is mainly nothingness. A scale model is one way of looking at distances that are too large to visualize The planets are RAREL
