I'm playing around with video here, but it's a serious lesson idea.
If you can take your students out to look at the world, let them bring something to write on (or record observations with your cell phone). If a field trip or class walk is out of the question, send home an assignment sheet and let families get in on it.
How many signs of fall can your class find? Changes in the colors of leaves may be the most obvious, but there might also be acorns on the ground and squirrels gathering them, geese flying south for the winter, people starting to wear sweaters or jackets, apples and pumpkins in the market, or fog.
Find an email penpal in another part of the country and compare the signs you find.
