Thanksgiving Science Activity for Upper Elementary and Middle School
This Thanksgiving science activity works well for students around ages 8–13 who are learning how to use the periodic table or need some extra practice with atomic numbers and element symbols.
Younger students may need help finding their first few elements, while middle school students should be able to work through the codes independently. It can be used as a November science warm-up, early finisher activity, science center, or seasonal periodic table review.
For an extra challenge, ask students to choose a few elements they found while solving the puzzle and record each element’s full name, atomic number, and symbol.
