As part of a series of electronic professional development experiences, the NASA Explorer Schools project and the National Science Teachers Association are hosting a free 90-minute Web seminar on Oct. 25, 2012, at 7:30 p.m. EDT. Learn about the relationships between air pressure, temperature, volume and cloud formation. Get an overview of the necessary conditions for cloud formation and then see how to make a cloud in a bottle. Information will be provided about an extension activity, the S'COOL Project, which involves student participation in authentic science.
