Grade: 8th Science: Unit 5: May the Force Be With You
Time Frame: February 10 – March 27
(6 Weeks)
Unit Description and Student Understandings: This unit focuses on demonstrating the magnetic fields of bar magnets and making comparisons to those of
Earth; demonstrating Newton’s laws of motion; defining gravity and its relationship to mass and distance between objects; and explaining relationships between
force, mass, and acceleration. Students develop an understanding of magnets and magnetism and how this force exists in nature. Students demonstrate Newton’s
laws of motion and how it relates to gravity. Students develop an understanding of the force of gravity and its effect on the behavior of objects on or near Earth, as
well as in space. This unit focuses on astronomy and space exploration: how the study of the Solar System’s structure, movements, and the continuing
developments in technology enable us to understand Earth and its place in the solar system—in the Milky Way galaxy. The student will understand the basics of
astronomy (i.e., bodies and events associated with the solar system, stars, and the universe, as well as Earth’s particular characteristics and how it is affected by the
Sun, the Moon, etc.). The student will understand discoveries made by modern astronomy and the technology that has been developed for space exploration.
Students will learn about those who paved the way for space flight and the knowledge gained from manned and unmanned space explorations.

Can students describe and predict the patterns of change that result in Moon phases and eclipses?
Can students identify angular relationships between Earth, the Sun, and Moon that result in the various phases of the moon?
Can students identify the alignments of Earth, the Sun, and Moon that result in solar and lunar eclipses?
Can students describe how scientists determine the size, composition, and temperatures of astronomical bodies?
Can students demonstrate their knowledge of the relationships between improvements in technology and subsequent discoveries in space?
