Description
This semester course is designed for the third/ fourth year high school student who is
interested in learning about the Universe. Astronomy is a rapidly evolving field fueled by
new technologies and novel theoretical insights. The important concepts are developed
without using sophisticated mathematics; rather they are explained using qualitative
reasoning, critical thinking and problem solving analogies. This is done in order to
explain the complexities of the subject matter without oversimplification.

Objectives
A. Science Standards
5.1
Science Practices: All students will understand that science is both a body
of knowledge and an evidence-based, model-building enterprise that continually
extends, refines, and revises knowledge. The four Science Practices strands
encompass the knowledge and reasoning skills that students must acquire to be
proficient in science.
5.2
Physical Science: All students will understand the physical science
principles, including fundamental ideas about matter, energy, and motion, are
powerful conceptual tools for making sense of phenomena in physical, living and
Earth systems science.
5.3
Life Science: All students will understand that life science principles are
powerful conceptual tools for making sense of complexity, diversity and
interconnectedness of life on Earth. Order in natural systems arises in accordance

5.4.12.A.4 – Analyze
simulated and/ or real data to
estimate the number of stars in
our galaxy and the number of
galaxies in our Universe.
The Sun is one of an
estimated two hundred
billion stars in our Milky
Way galaxy, which
together with over one
hundred billion other
galaxies make up the
Universe.
Desired Results:
Students will ...
 Describe the overall structure of the Milky Way galaxy,
and specify how the various regions differ from one
another.
 Explain the importance of variable stars in determining the
size and shape of our galaxy.
 Describe the orbital paths of stars in different regions of the
galaxy, and explain how these motions are accounted for by
our understanding of how the galaxy formed.
 Discuss some possible explanations for the existence of the
spiral arms observed in our own and many other galaxies.
 Explain what studies of galactic rotation reveal about the
size and mass of the galaxy.
 Discuss the distance-measurement techniques that enable
astronomers to map the Universe beyond the Milky Way.

State how Hubble’s Law explains objects in the
observable Universe.
Standard: 5.4 Earth Systems Science: All students will understand that Earth operates as a set of
complex, dynamic, and interconnected systems, and is part of the all-encompassing system of the
Universe.
Strand: Objects in the Universe: Our universe has been expanding and evolving for 13.7 billion
years under the influence of gravitational and nuclear forces. As gravity governs its expansion,
organizational patterns, and the movement of celestial bodies, nuclear forces within stars govern its
evolution through the processes of stellar birth and death. These same processes governed the
formation of our solar system 4.6 billion years ago.
