Classroom Presentation

The classroom presentation is comprised of short discussions, demonstrations, and science activities related to astronomy.

The first set of demonstrations deal physics demowith the phases of matter and how they vary depending on the material.  Liquid nitrogen and dry ice (solid carbon dioxide) are used to show students how some elements have freezing and boiling points much much colder than substances they encounter everyday, such as water.  To illustrate just how cold these two substance are, various objects are frozen, and some fun properties that arise from the relationship between temperature, pressure, and volume are explored.

Following this is the making physics demoof a model comet.  The importance of comets in space science is discussed along with the physical conditions of space (temperature, etc.), relating back to the first part of the classroom presentation.  Topics such as space exploration, telescopes, or career opportunities in science and engineering can also be discussed.
