General Lesson Information
 Lesson Plan ID: 34743 Title: Rollin' Through the Solar System: Creating a Scaled Model Overview/Annotation: First, students will view an engaging video about the recent arrival of the New Horizons spacecraft at Pluto. Students will create a sketch of the solar system to show their current understanding of the relative sizes and distances of the objects in our solar system. Students will then scale the diameters of the Sun, eight main planets, and Pluto, as well as the planets' distances from the sun. Students will be required to utilize mathematical skills, such as division, rounding, and metric system conversions. After scaling the diameters and orbits of the objects in our solar system, students will create a scaled model of the solar system using a roll of toilet paper.This lesson results from a collaboration between the Alabama State Department of Education and ASTA.
Associated Standards and Objectives
Content Standard(s):
 Science SC2015 (2015) Grade: 6 Earth and Space Science 3 ) Develop and use models to determine scale properties of objects in the solar system (e.g., scale model representing sizes and distances of the sun, Earth, moon system based on a one-meter diameter sun). Unpacked Content Scientific And Engineering Practices:Developing and Using ModelsCrosscutting Concepts: Scale, Proportion, and QuantityDisciplinary Core Idea: Earth's Place in the UniverseEvidence Of Student Attainment:Students: Develop models to determine scale properties of objects in the solar system. Use models to determine scale properties of objects in the solar system.Teacher Vocabulary:Model Scale Scale model Properties Size Distance Diameter Solar system Planet Moon Sun Asteroid Asteroid belt Celestial bodyKnowledge:Students know: A (scale) model is a representation or copy of an object that is larger or smaller than the actual size of the object being represented. Measurements may be multiplied or divided to correctly scale objects in a model. Charts and data tables may be analyzed to find patterns in data. Patterns can be used to describe similarities and differences in objects in the solar system. Systems and their properties may be described using more than one scale.Skills:Students are able to: Develop a model of objects in the solar system and identify the relevant components. Describe that different representations illustrate different characteristics of objects in the solar system, including differences in scale. Use mathematics and computational thinking to determine scale properties. Describe that two objects may be similar when viewed at one scale but may appear to be quite different when viewed at a different scale.Understanding:Students understand that: The solar system consists of the sun and a collection of objects, including planets, their moons, and asteroids that are held in orbit around the sun by its gravitational pull on them. Space phenomena can be observed at various scales using models to study systems that are too large or too small.AMSTI Resources:AMSTI Module: Researching the Sun-Earth-Moon System Exploring Planetary Systems Alabama Alternate Achievement Standards AAS Standard: SCI.AAS.6.3- Use a model to compare the relative sizes of objects in the solar system (e.g., sun, Earth, moon).

Local/National Standards:

Primary Learning Objective(s):

Students will develop a scale model to represent the diameters of the sun, eight main planets, and Pluto.

Students will develop a scale model to represent the distances between the objects in our solar system.

Students will use the model they create to describe the relative diameters and orbits of the objects in our solar system.

Students will use mathematical skills (division, rounding, and metric system conversion) to create a scale model of the solar system.

NASA Video Clip (1:46 minutes)Build a Solar System (planets only) Website for scale factorBuild a Solar System (additional celestial bodies) Website for extension activity Background/Preparation: Students should have a basic understanding of the objects included in our solar system. In addition, students should understand that the solar system is so vast, we have to scale it down in order to understand the relationships between objects in our solar system. Students should be able to develop a scale model with teacher assistance, be able to round numbers to a specific place value, and complete metric system conversions (millimeters to meters).
