This Meeting is hosted and sponsored by the Department of Physics at the University of Maryland, College Park with additional funding from the UVA Department of Physics, the VT Department of Physics, and the VT College of Science.    


The Fall 2023 Meeting of the Chesapeake Section of the American Association of Physics Teachers (CSAAPT) will be held on Saturday, October 21, 2023 at the University of Maryland College Park.

No membership required!                      
You do not have to be an AAPT or CSAAPT member to attend. We welcome participation of all physics/science teachers and students in the region (DC, DE, MD, VA and neighboring states) as well as anyone interested in physics education, or physics in general.

The semiannual CSAAPT meetings are a great forum to exchange ideas on novel teaching techniques and economical physics demonstrations, and to meet a fascinating cohort of physics education enthusiasts.

This meeting is semi-virtual.  The in-person venue is the Physical Sciences Complex Rooms 0135, 2136, and 3150 at the University of Maryland College Park.  See the Meeting Location page for details.  The Meeting will be broadcast on Zoom so that people from afar (both presenters and attendees) can join in.  

Lodging Support!                      
We have limited funds to provide up to $350 in lodging support to high school physics teachers.  Please see the Travel and Lodging Info page for details.                     


  • Continental breakfast will be available at the meeting site from 8:00AM.  Lunch will also be provided.   
  • Presentations are expected to start at around 9:00AM and continue until around 5:00PM.  (Actual times will depend on the number of abstracts submitted.)   
  • Timetable will be created after the abstract submission deadline of Saturday, September 30, 2023.

  • Prof. Maria Molina (UMD, Department of Atmospheric & Oceanic Science)             

Title:  Understanding our Changing Climate with Physics and Machine Learning

Abstract: Rising global temperatures related to increased greenhouse gas emissions since the start of the Industrial Revolution are contributing to changes in the Earth system with cascading effects across environments and ecosystems. While observational limitations and feedbacks between integrated system components complicate our ability to model future changes, the field of physics, as applied to the matter that makes up the Earth’s atmosphere, ocean, land, and cryosphere, can help us describe and anticipate the response to changes in the atmosphere’s composition. A strong educational background in introductory physics can lay the needed foundation to tackle many of the challenges related to our changing climate. In this talk, I will discuss the physical basis of our changing climate, why it can be very challenging to characterize certain changes in extreme weather and climate, and what some of the latest research says about these changes. The talk will close with a discussion about the use of machine learning to understand our changing climate and the disproportionate vulnerability faced by historically marginalized communities to extreme weather and climate change.

Bio: Maria J. Molina is an Assistant Professor within the Department of Atmospheric and Oceanic Science at the University of Maryland and an Affiliate Faculty with the University of Maryland Institute for Advanced Computer Studies (UMIACS). She is also affiliated with the National Center for Atmospheric Research (NCAR) in Boulder, Colorado and serves as an Adjunct Assistant Professor within the Department of Marine, Earth, and Atmospheric Sciences at North Carolina State University. Maria is Vice-Chair of the American Meteorological Society (AMS) Committee on Artificial Intelligence Applications to Environmental Science and a member of the AMS Board on Representation, Accessibility, Inclusion, and Diversity (BRAID). Her research group focuses on climate and extremes data science.       


Title: Do You See What I See?: Smartphones as Visualization Tools  

Abstract: Smartphones and other mobile devices can be used to enhance laboratory experiences because of their many internal sensors (accelerometer, gyroscope, light meter, sound meter etc.). During this workshop, use your own device (or borrow one from the presenters!) to cycle through two sets of team-based, data-verified challenges using everyday materials. In the first set of challenges, participants will work in pairs to complete up to seven tasks with Physics Toolbox Play, learning about fundamental physics principles and sensor capabilities. In the second set, participants will use Physics Toolbox LiDAR Motion to match motion graphs using novel LiDAR technology on the iPhone. Finally, participants will have time to brainstorm other ways that they might use smartphones to enhance existing laboratory experiences, from in-the-field data collection experiences to distance learning.   

Bios: Rebecca Vieyra is a former high school physics teacher who became a nationally-recognized science educator before serving in roles at the American Association of Physics Teachers, Organization of American States (a diplomatic agency), and PhET Interactive Simulations. Born in central Illinois, Rebecca received her B.S. in Physics Education from Illinois State University and Ph.D. in Science Education from the University of Maryland-College Park. She earned National Board Teacher Certification in 2010, was awarded the Presidential Award for Excellence in Math and Science Teaching by Barack Obama in 2013, and was selected by NASA as an Albert Einstein Fellow in 2014.

Chrystian Vieyra is an Android and iOS app developer with a specialty in sensor data. In addition to working full-time at a major global telecommunications company, he established and continues to develop Physics Toolbox, a suite of apps to advance science education and research that have been used by more than 2 million people since 2013. Born in Celaya, Mexico, he immigrated to the United States to complete his B.S. in Computer Science from Western Illinois University.
