The Periodic Table represents more than 5,000 years of human discovery. The University of Waterloo marked the 2019 International Year of the Periodic Table (IYPT) with a worldwide collaboration that chronicles this amazing story in a timeline illustrated by students from 118 schools in 28 countries, including our very own tile from Spearfish High School. See link below. 

Learn about the discovery of the elements through several resources on this site.
