Students create an anchor chart displaying the similarities and differences between the four seasons. Student could pick a specific object such as a tree to represent what the tree looks like in each season. Also a great way to integrate weather concepts.
Such a fun art and writing idea - have student write about their favorite season, then draw what they would see out their window in that season. They can then "hang curtains" on their window. My favorite weather or season bulletin for October
