UNIT 2 DESIGN Earth and Space Science (Space Systems) (6 Weeks) Essential Questions ●
●
How do the Earth, Moon, and Sun interact to affect the conditions on Earth? How does Earth’s physical characteristics compare to those of other objects in the solar system? ● How are these characteristics determined? ● What determines the movement of objects around the sun? ● What are the four giant planets in the outer solar system? Knowledge and Skills ●
Develop and use a model of the Earth­sun­moon system to describe the cyclic patterns of lunar phases, eclipses of the sun and moon, and seasons. ● Develop and use a model to describe the role of gravity in the motions within galaxies and the solar system. ● Analyze and interpret data to determine scale properties of objects in the solar system. Science and Engineering Practices ●
●
Developing and Using Models Analyzing and Interpreting Data Core Ideas ● The Universe and Its Stars § Patterns of the apparent motion of the sun, the moon, and stars in the sky can be observed, described, predicted, and explained with models. (MS­ESS1­1) § Earth and its solar system are part of the Milky Way galaxy, which is one of many galaxies in the universe. (MS­ESS1­2) ● Earth and the Solar System § 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. (MS­ESS1­2),(MS­ESS1­3) § This model of the solar system can explain eclipses of the sun and the moon. Earth’s spin axis is fixed in direction over the short term but tilted relative to its orbit around the sun. The seasons are a result of that tilt and are caused by the differential intensity of sunlight on different areas of Earth across the year. (MS­ESS1­1) * The solar system appears to have formed from a disk of dust and gas, drawn together by gravity. (MS­ESS1­2) Crosscutting Concepts ●

Patterns Scale, Proportion, and Quantity Systems and System Models CCCSS Connections ELA ● Cite specific textual evidence to support analysis of science and technical texts. ● Integrate quantitative or technical information expressed in words in a text with a version of that information expressed visually (e.g., in a flowchart, diagram, model, graph, or table). ● Integrate multimedia and visual displays into presentations to clarify information, strengthen claims and evidence, and add interest. Mathematics ● Reason abstractly and quantitatively. ● Model with mathematics. ● Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities. ● Recognize and represent proportional relationships between quantities. ● Use variables to represent numbers and write expressions when solving a real­world or mathematical problem; understand that a variable can represent an unknown number, or, depending on the purpose at hand, any number in a specified set. ● Use variables to represent quantities in a real­world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities.

E­4395­B781­B24F0CCC4E62 Assessment Plan MS­ESS1­1. Develop and use a model of the Earth­sun­moon system to describe the cyclic patterns of lunar phases,eclipses of the sun and moon, and seasons. [Clarification Statement: Examples of models can be physical, graphical, or conceptual.] eScience Space Science Chapter 2 Lesson 1, 3 Review: eScience Space Science Chapter 2 Lessons 1 and 3 Think, Review, Apply, After Lesson Hands­on Lab: eScience Space Science Chapter 2 Lesson 1 and 3 Investigate Simulation Lab: astro.unl.edu/naap/motion1/animations/seasons_ecliptic.html Test: eScience Space Science Chapter 2 test (modified to exclude topics not covered) MS­ESS1­2. Develop and use a model to describe the role of gravity in the motions within galaxies and the solar system. [Clarification Statement: Emphasis for the model is on gravity as the force that holds together the solar system and Milky Way galaxy and controls orbital motions within them. Examples of models can be physical (such as the analogy of distance along a football field or computer visualizations of elliptical orbits) or conceptual (such as mathematical proportions relative to the size of familiar objects such as students’ school or state).] [Assessment Boundary: Assessment does not include Kepler’s Laws of orbital motion
or the apparent retrograde motion of the planets as viewed from Earth.] Review: eScience Space Science Chapter 3 Lesson 1 Think, Review, Apply, After Lesson

Analyze and interpret data to determine scale properties of objects in the solar system. [Clarification Statement: Emphasis is on the analysis of data from Earth­based instruments, space­based telescopes, and spacecraft to determine similarities and differences among solar system objects. Examples of scale properties include the sizes of an object’s layers (such as crust and atmosphere), surface features (such as volcanoes), and orbital radius. Examples of data include statistical information, drawings and photographs,and models.] [Assessment Boundary: Assessment does not include recalling facts about properties
of the planets and other solar system bodies.] Review: eScience Space Science Chapter 3 Lessons 2 ­ 4 Think, Review, Apply, After Lesson Hands­on Lab: eScience Space Science Chapter 3 Lessons 2 ­ 4 Investigate Data Lab: nssdc.gsfc.nasa.gov/planetary/factsheet/; http://www.bobthealien.co.uk/index2.htm
