  Activity: Chemistry Pyramids Mark as Favorite (7 Favorites)

  In this activity, students will use the periodic table, combined with math and logic to solve several chemistry themed pyramid puzzles.

Students are challenged with determining the missing element symbols in each puzzle, but first must use a periodic table to find the atomic number for each element symbol appearing in the puzzle. This activity is a fun challenge for students and provides the opportunity to strengthen logic and reasoning skills.
