Newspaper, a Yardstick, and Some Fun

Last week in class we continued with our Weather unit. For years we have been doing a demonstration with the students about air pressure, using a yardstick and a newspaper. The class always loves this demonstration and causes a great deal of discussion as to why this happens using these materials. I found this video, from what appears to be a high school class doing this same demonstration. This teacher does a great job explaining why this happens.
