  Activity: Periodic Table of Mistakes Mark as Favorite (99 Favorites)

  In this activity, students will examine a periodic table that contains 25 mistakes. Students will be tasked with comparing the Periodic Table of Mistakes to a real periodic table in order to determine what mistakes are present. This activity provides an opportunity for students to become more familiar with the periodic table, including element names, symbols and placement, as well as trends in atomic mass.
