AGECO 122: Atmospheric Environment: Growing in the Wind (Fall 2017)

Growing in the Wind is for first-year students who are interested in learning about the atmospheric environment and its influence on animals, plants, and humans.

Department(s)

  • Plant Science

Description

AGECO 122 Atmospheric Environment: Growing in the Wind is for students who are interested in learning about the dynamic effects of weather on plants and animals. It is about how processes at the ground surface and in the air govern weather conditions on Earth.

This course focuses on five major weather elements: energy, temperature, moisture, pressure, and wind and how these factors govern ecosystems and habitation of our planet. Emphasis is also given to 1) human impacts on weather and climate and 2) current environmental issues involving the atmosphere.

The lectures are organized around the central theme that the unequal distribution of incoming solar energy (both spatially and temporally) produces temperature and pressure contrasts at Earth’s surface and in the atmosphere that in turn cause storms and control the weather and climate.

"Whether the weather is cold, or whether the weather is not, we'll weather the weather, whatever the weather, whether we like it or not!"

  • how the major weather elements interact to govern storms, daily weather, and climate;
  • how humans are changing our atmospheric environment.

Lectures

The lecture schedule for this course is provided below. The schedule may change slightly as the course progresses; however, if this happens you will be informed either in class or by email. Slides and lecture notes are available on the Canvas website as PowerPoint presentations. There will be Key Concept assignments and quizzes given in lecture throughout the course of the semester. They will be administered with five minutes left in the lecture period and cover the material discussed in the preceding 45 minutes. Each Key Concept assignment and quiz will be worth five points.

Readings

The chapters for the readings are listed next to the lecture topics below. A total of ten points can be earned for reading each chapter by taking the associated Open Book Chapter Quiz that is available on the Canvas website. The quizzes consist of ten questions and will last for ten minutes. The quizzes can be taken a total of three times and only the highest grade will be recorded. Quizzes will be available to take before and until 11:50 p.m. on the day that the readings are assigned and unavailable thereafter. The schedule for the last day when each Open Book Chapter Quiz is available is provided below.

Exams

Exams will consist of short essay and multiple choice questions. They will cover lecture, reading, and project materials.

Labs

There will be three class lab projects during the semester. Students will work in small groups on the assignments and make oral presentations of their results to the class.

Grading

There are 765 points that may be earned in this course. Grades are generally based on a straight scale (90+% is an A, 80-90% is a B, 70-79% is a C, 60-69% is a D, <60% is an F).

Penn State Statements

The Penn State Principles

The Pennsylvania State University is a community dedicated to personal and academic excellence. The Penn State Principles were developed to embody the values that we hope our students, faculty, staff, administration, and alumni possess. At the same time, the University is strongly committed to freedom of expression. Consequently, these Principles do not constitute University policy and are not intended to interfere in any way with an individual's academic or personal freedoms. We hope, however, that individuals will voluntarily endorse these common principles, thereby contributing to the traditions and scholarly heritage left by those who preceded them, and will thus leave Penn State a better place for those who follow.

Academic Integrity

Penn State and the College of Agricultural Sciences take violations of academic integrity very seriously. Faculty, alumni, staff and fellow students expect each student to uphold the University's standards of academic integrity both in and outside of the classroom. Academic integrity is the pursuit of scholarly activity in an open, honest and responsible manner. Academic integrity is a basic guiding principle for all academic activity at The Pennsylvania State University, and all members of the University community are expected to act in accordance with this principle. Consistent with this expectation, students should act with personal integrity, respect other students' dignity, rights and property, and help create and maintain an environment in which all can succeed through the fruits of their efforts. Academic integrity includes a commitment not to engage in or tolerate acts of falsification, plagiarism, misrepresentation or deception. Such acts of dishonesty violate the fundamental ethical principles of the University community and compromise the worth of work completed by others (see Faculty Senate Policy 49‐20 and G‐9 Procedures.)

Code of Conduct and Student Conduct Procedures

Academic Integrity Guidelines for the College of Agricultural Sciences

A lack of knowledge or understanding of the University's Academic Integrity policy and the types of actions it prohibits and/or requires does not excuse one from complying with the policy.

Nondiscrimination Statement

The University is committed to equal access to programs, facilities, admission and employment for all persons. It is the policy of the University to maintain an environment free of harassment and free of discrimination against any person because of age, race, color, ancestry, national origin, religion, creed, service in the uniformed services (as defined in state and federal law), veteran status, sex, sexual orientation, marital or family status, pregnancy, pregnancy-related conditions, physical or mental disability, gender, perceived gender, gender identity, genetic information or political ideas. Discriminatory conduct and harassment, as well as sexual misconduct and relationship violence, violates the dignity of individuals, impedes the realization of the University's educational mission, and will not be tolerated. Direct all inquiries regarding the nondiscrimination policy to Dr. Kenneth Lehrman III, Vice Provost for Affirmative Action, Affirmative Action Office, The Pennsylvania State University, 328 Boucke Building, University Park, PA 16802-5901, Email: kfl2@psu.edu, Tel (814) 863-0471.

Disability

Penn State welcomes students with disabilities into the University's educational programs. Every Penn State campus has an office for students with disabilities. The Office for Disability Services (ODS) Web site provides contact information for every Penn State campus. For further information, please visit the Office for Disability Services Web site.

In order to receive consideration for reasonable accommodations, you must contact the appropriate disability services office at the campus where you are officially enrolled, participate in an intake interview, and provide documentation. If the documentation supports your request for reasonable accommodations, your campus's disability services office will provide you with an accommodation letter. Please share this letter with your instructors and discuss the accommodations with them as early in your courses as possible. You must follow this process for every semester that you request accommodations.

Mental Health Services

Many students at Penn State face personal challenges or have psychological needs that may interfere with their academic progress, social development, or emotional wellbeing. The university offers a variety of confidential services to help you through difficult times, including individual and group counseling, crisis intervention, consultations, online chats, and mental health screenings. These services are provided by staff who welcome all students and embrace a philosophy respectful of clients' cultural and religious backgrounds, and sensitive to differences in race, ability, gender identity and sexual orientation.
