Dear Educator,
Many parts of the country have been unseasonably warm this fall, but still, leaves are changing color, pumpkins have been carved, and the season is in full swing with Thanksgiving feasts coming soon. This week, we look at all things seasonal for fall. One of the many interesting things about fall is that is has more than one name. We also call the season autumn, but in Middle English, the name for fall was haerfest, which meant “to bring in all the crops,” or harvest time. The term fall for the third season of the year is short for “fall of the leaf.” Speaking of leaves, dry weather and reduced sunlight lead to less green chlorophyll in leaves, allowing other pigments in the leaves to show. These include the yellows and oranges. Some trees produce chemicals that make leaves red. Freezing weather puts an end to that process. Students will learn more about why leaves change color, below. Let’s delve into more than just leaves as we celebrate the season that many people identify as their favorite of the whole year.
