Periodic Puzzles are a set of engaging activities designed to help students become familiar with the Periodic Table.  Different puzzle sets are designed to teach concepts such as individual elements, classifications, and features.

Description and Details:

  • Designed for the Introductory Level Science Class (middle school and early high school level)
  • Introductory level is suitable for the General Science Classroom (Grades 4-10), Intermediate Level (Grades 10-11), Advanced Level (Grade 11-post-secondary)
  • Each puzzle set focuses on different patterns, concepts and academic levels of the periodic table of elements (introductory level chemistry to advanced level chemistry, *AP, *IB, and *introductory university level chemistry)
  • Students work individually, in pairs, or in small groups of 4 to 6 to arrange the pieces all at once into the proper region of the periodic table.The time it takes to complete each puzzle is recorded and compared with other groups. Students can also take turns placing the pieces in the appropriate location until the puzzle is completed.
  • Students can also receive one tile and determine a specific number of physical or chemical properties depending on the location of the element on the periodic table, or discuss as a class.
  • Periodic Table Puzzles can also be used to introduce, review, and formatively assess student understanding of specific concepts.
