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.
Fall 2020 Undergraduate Courses
Planet Earth: Evolution of the Habitable World (3)
(001) David O'Brien
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.
Astrobiology: A Planetary Perspective (3)
We will explore questions about the origin, evolution, and future of life on Earth and the possibility of life arising independently elsewhere in the Universe. We will examine what it means for a planet to be habitable, both in terms of basic necessities for living organisms to function and environmental limits to their ability to survive. Finally, we will review different approaches for searching for life within the Solar System and beyond using direct and remote sensing techniques. PTYS 214 is a Tier II Natural Science course in the University general education curriculum. PTYS 214 is cross-listed with ASTR 214 and GEOS 214. Course is equivalent to ASTR 202 (students may not receive credit for both courses).
Teaching Teams Professional Development Workshop (3)
Professional development for undergraduates of all disciplines in areas of peer instruction and mentoring, leadership, public speaking, group dynamics, and interview skills; also assists students with preceptorships.
Life on Mars: Fact and Fiction (3)
Life on Mars is likely to be a scientific "hot topic" for the rest of your life. After this class, you should have a good understanding of what planetary scientists think about the chances of life on Mars, why they think that, and how current and future spacecraft missions plan to address that. In addition, since life on Mars has been the subject of some classic science fiction for more than 100 years, with no signs of letting up, you should understand how that science fiction relates to science. My real goal is that as the current debate resolves itself, and as spacecraft explore Mars during the next few decades, you'll understand what's going on and which claims are important, and that as you read or watch science fiction dealing with Mars, you'll appreciate how it relates to past and present science and sci-fi. PTYS 342 may not be applied toward the PTYS undergraduate minor.
Teaching Teams Internship (1-6)
Internship for students who have completed PTYS 297A (formerly LASC 297A), with at least one semester as a preceptor of a university-level course) to continue their reaching team education. Course covers elements of learning environments, communication skills, providing feedback, performance evaluation, and cooperative learning strategies.
Professional Development in a Digital Age (1-3)
Professional development in areas that are affected by transition to digital formats. Students will learn about elevator pitches, communication, utilizing professional technologies, resumes and curriculum vitaes, online resumes and portfolios, professionalism within social media, searching for jobs online, and interviewing.
Asteroids, Comets and Kuiper Belt Objects (3)
This is an introduction to the "minor planets," the asteroids, comets and Kuiper Belt objects. The focus will be on origin and evolution (including current evolution), as well as techniques of study. It will include an evening at the telescope of an asteroid search program. Graduate-level requirement includes some original work or calculations in the paper/project submitted and to research one of the primary topics and lead the class discussion of it. PTYS 416 may be co-convened with PTYS 516.
Dynamic Meteorology (3)
Thermodynamics and its application to planetary atmospheres, hydrostatics, fundamental concepts and laws of dynamic meteorology. Prerequisite: PHYS 426 or consent of instructor. ATMO is home department.
Advanced Teaching Teams Internship (1-6)
This advanced internship is for students who have completed PTYS 393. Course covers elements of learning environments, communication skills, providing feedback, performance evaluation, and cooperative learning strategies; it requires students to peer lead workshop sections within the Teaching Teams Program alongside a faculty/staff mentor.
