This is the season to find all kinds of nuts: acorns, hickory nuts, walnuts, beech nuts. The black walnuts are falling, now, on the road. They're huge, green balls nearly the size of tennis balls, though they tend to break apart if you kick them too hard. Finding hickory nuts is always a race with the squirrels and birds.
Go out an look for some nuts. Draw pictures of what you find (or take photos). Sit quietly and notice what animals come to investigate the nuts.
