Middle school students will learn about the science of phenology by journaling.

It’s sweater weather in both hemispheres and seasonal researcher and expert Phenologist Dr. Libby Ellwood weighs in with amazing information about why fall smells so good, why leaves change color, why we like to cronch them, historical records of blossoms and twigs, bird migrations, Daylight Savings, seasonal mythbusting, pumpkin spice vs. apple cider, the best temperature to wear sweaters, why the Halloween aisle springs up in summer and how global temperature shifts affect the whole food web.
