Content: This "Air Pressure Demonstration" assignment was created for GS4401, Science and Science Teaching in the Elementary School, Fall 2007. It was made under the advisement of this course's instructor, Jeff Goodman. Impact: In this assignment, I helped students understand the concept of air pressure. The concept of pressure can be very difficult for students to understand. Hence, I believe that a demonstration will not only spark student's interest, but it will help the students learn about air pressure. The document entitled, Air Pressure Demonstration, includes the materials used, an explanation of the targeted science concepts, a detailed procedure of the demonstration with diagrams, questions to ask, and an annotated list of resources to use.
