NASA Explorer Schools & the Plymouth Meteorology Center The BIG Weather Workshop
Workshop Descriptions:Clouds - Are you in a fog about clouds? This workshop will help you discover ways to access excellent websites/resources such as S'COOL and GLOBE. We will also share ideas for hands-on projects and literature and inquiry based activities that support NH Science Framework Standards. Nan Munsey and Linda Walker, NASA Explorer School (Indian River School). Boyd Room 239Weather Station - Your students can be meteorologists using real scientific data from your own area by constructing a weather station at your school. In this workshop you will learn how to use meteorological instruments, how to interpret both local and global data, and how it all aligns with the state standards. Attendees will also receive help on weather station design and where to purchase equipment. Koby van Beest and Mary Pat Acerno, NASA Explorer School (Mascoma High School). Boyd Room 225PSU Weather Center Web Resources - The PSU Meteorology Program started its web page in April 1994. Over the years, the content has expanded greatly and offers not only access to a wide variety of current meteorological data, but also access to archived data and tutorials. The site now averages over 1,000,000 accesses per week. This workshop session will focus on a demonstration of various resources and how they can be used to address some of the state's education standards. There will be an overview and description of resources and then some "hands-on" exercises for teachers to explore some of the sites extensive capabilities. Dr. James P. Koermer, Professor of Meteorology, PSU Boyd Room 306 Identifying Weather Patterns: Drawing Isotherms -
Participants in this workshop will examine and analyze current temperature data, to identify patterns and garner meaning from the data. We will then investigate what these kinds of patterns can tell us about local and regional weather, and how this information relates to the weather depictions and changes seen on daily weather maps. Marsha Rich, Datastreme Project Boyd Room 303
