Fall Colors, Temperature, and Day Length by: Stephen Burton, Heather Miller, and Carrie Roossinck

Journal ArticleDigital resources are stored online in your NSTA Library.

Along with the bright hues of orange, red, and yellow, the season of fall represents significant changes, such as day length and temperature. These changes provide excellent opportunities for students to use science process skills to examine how abiotic factors such as weather and temperature impact organisms. The activity described in this article uses available internet data to encourage students to explore the relationship between seasonal patterns and climate (plant phenology) as well as day-length data. In particular, students develop and test hypotheses to explain latitudinal differences in leaf-color change.

Excellent use of easily available climatic data to engage students in inquiry by examining the relationship between fall leaf color, temperature, and day length. This investigation is a great lead-in to biomes and will help students understand the connection between climate, organisms, and biomes. Clearly marked maps and graphs can be used in your lesson or as a template for your own geographic region.
