This course develops a planetary perspective on the evolutionary processes that shaped Earth throughout history. We will examine why Earth is habitable, that is, why any kind of life can live on it, we will discuss the unique influences that biological processes and atmosphere/ocean systems have on each other, and we will review current notions of climate change, including evidence for the influence of human activities on it. This interdisciplinary treatment of Earth and its sister planets will encourage students to think about how science and engineering must be applied to today's challenges if humankind is to have a promising future on (and off) this planet. PTYS 170A1 is a Tier I Natural Science course in the University's general education curriculum. This course is co-convened (cross-listed) with ASTR 170A1.
Spring 2021 Undergraduate Courses
The Universe and Humanity: Origin and Destiny (3)
The Universe And Humanity: Origin And Destiny places Earth and humanity in a broad cosmic context. Topics range from the Big Bang cosmology to human consciousness with emphasis on the events and evolutionary processes that define the physical universe and our place in it. PTYS 170B2 is a Tier I Natural Science course in the University's general education curriculum. This course is co-convened (cross-listed) with ASTR 170B2.
Exploring Our Solar System (3)
Our Solar System is filled with an incredible diversity of objects. These include the sun and planets, of course, but also many hundreds of moons—some with exotic oceans, erupting volcanoes, or dynamic atmospheres. Billions of asteroids and comets inhabit the space between and beyond the planets. Each body is unique, and has followed its own evolutionary history. This class will explore our current understanding of the Solar System and emphasize similarities that unite the different bodies as well as the differences between them. We will develop an understanding of physical processes that occur on these bodies, including tectonics, impact cratering, volcanism, and processes operating in their interiors, oceans, and atmospheres. We will also discuss planets around nearby stars and the potential for life beyond Earth. Throughout the class, we will highlight the leading role that the University of Arizona has played in exploring our Solar System.
Course Objectives: Students who engage with this course will develop a broad understanding of many fundamental concepts in planetary science and gain an appreciation for the discoveries and reasoning that leads to this understanding. They will learn to collect their own data as well as gather relevant supporting information from a variety of outside sources. Throughout the semester students will be demonstrating their grasp of course material by composing written assignments at a level their peers outside of the class will understand (a.k.a., Students on the Street, or SOS). During the term project students will be assisted in working with telescopes to obtain astronomical images using their own smart phone cameras. Students will learn during in-class workshops how to use their own images to then construct a time-lapse animation. Expected Learning Outcomes: Upon successful completion of this course students will be able to (1) access and use information and data from a variety of sources, including their own activities, (2) critically evaluate this information and data for reliability in supporting fundamental concepts, (3) effectively communicate an understanding of these concepts to their SOS peers by synthesizing the information and data they have gathered, (4) demonstrate practical skills with a variety of software, including Word, Excel, Keynote, PowerPoint, and image/video editing apps.
PTYS 206 is cross-listed with ASTR 206. Course requisites: Two courses from Tier One, Natural Sciences.
Physics of the Solar System (3)
Survey of planetary physics, planetary motions, planetary interiors, geophysics, planetary atmospheres, asteroids, comets, origin of the solar system. Prerequisites: PHYS 142 or 251. PTYS 403 is a required course for the PTYS Minor. Equivalen to ASTR/GEOS/PHYS 403.
In-depth class about the planet Mars, including origin and evolution, geophysics, geology, atmospheric science, climate change, the search for life, and the history and future of Mars exploration. There will be guest lectures from professors and research scientists with expertise about aspects of Mars. There will be lots of discussion of recent results and scientific controversies about Mars. Graduate-level requirements include the completion of a research project that will be presented in class as well as a report. The research project could be analysis of Mars datasets, a laboratory experiment, or new theoretical modeling. Regular grades are awarded for this course: A B C D E. Prerequisite(s): PTYS 411, Geology of the Solar System is strongly recommended but not required. Equivalent to/crosslisted: ASTR 442, GEOS 442. May be convened with: PTYS 542.
