Activity 24 Teacher Guide: Mixing Ratios or Parts per Million, Billion In this serial dilution activity, connections are made to atmospheric mixing ratios. Background Certain gases such as ozone occur in the atmosphere in very tiny amounts. In the stratosphere, for instance, you may find only one to ten ozone molecules for every one million molecules of other gases. This amount is called one to ten parts per million (ppm). Measurements such as parts per million can be expressed in terms of volume or mass. Learning Goals Students will understand that a mixing ratio is the concentration of a certain substance expressed in parts per million or parts per billion by volume.

Religious Roots The origins of the fundamental reciprocal relationship between physical violence and physical pleasure can be traced to philosophical dualism and to the theology of body/soul relationships.

Nobody said it better than Francis Bacon, back in 1605: For myself, I found that I was fitted for nothing so well as for the study of Truth; as having a mind nimble and versatile enough to catch the resemblances of things … and at the same time steady enough to fix and distinguish their subtler differences; as being gifted by nature with desire to seek, patience to doubt, fondness to meditate, slowness to assert, readiness to consider, carefulness to dispose and set in order; and as being a man that neither affects what is new nor admires what is old, and that hates every kind of imposture. A shorter version is the art of being right. More definitions... Program for Critical Thinking Program for better decision making
