as a learning experience. An example of the use of deceased animals is in biology courses. In biology‚ students learn about the body of creatures in nature. As a part of this course the students usually have to perform a dissection of some sort. Most classes perform dissections on frogs‚ piglets‚ or cats. This class activity has been around for years in many classrooms‚ especially those around the United States of America. Much like deceased animals‚ live animals can be used for scientific research

The word phlogiston was first used early in the 18th century by the German chemist Georg Ernst Stahl. Stahl declared that the rusting of iron was also a form of burning in which phlogiston was freed and the metal reduced to an ash or calx. The theory was superseded
