Atmospheric pressure is defined as the force per unit area exerted against a surface by the weight of the air above that surface. In the diagram below, the pressure at point "X" increases as the weight of the air above it increases.

The activitites establish the concepts of atmospheric pressure, differences in pressure, how changing volume affects pressure, and a molecular model of how air pressure arises. Modified from the 5th grade ... c) Students will have a better understanding of how atmospheric air pressure arises, and is always present.

Air pressure is the force exerted on you by the weight of tiny particles of air (air molecules). Although air molecules are invisible, they still have weight and take up space. Since there's a lot of "empty" space between air molecules, air can be compressed to fit in a smaller volume.

In the homosphere each gas exerts a partial pressure, the product of the total atmospheric pressure and the concentration of the gas. Thus as oxygen represents about 21% of the composite gases, the partial pressure of oxygen is about 21% of the atmospheric pressure at any altitude within the homosphere.
