The Origin of the Elements

byStuart Surrey

In general, most high school chemistry courses around the country teach students about the elements from an organizational point of view. That is, the elements are taught in conjunction with the development of the periodic table. Students learn about the arrangement of the elements based on increasing atomic numbers, similar chemical and physical properties, as well as trends within the periodic table. Whereas most high school chemistry textbooks briefly mention the occurrence and/or abundance of specific elements on Earth or in the atmosphere, they rarely give any insight into the actual origin of the elements. Therefore, the aim of this curriculum unit is to present the students with a basic understanding of how and where the elements were formed prior to discussing the periodic table. This will include current information on Big Bang or primordial, stellar, and supernova nucleosynthsis. In doing so, the students will study the history of the Big Bang theory and stellar evolution as a means of understanding the origin of the elements as well as stimulating interest in astronomy and cosmology.
