This powerpoint comes with one slide on each season. There are common knowledge aspects identified with each season. Then there is a question to get the students thinking about what they think about when they hear a particular season. At the end of the powerpoint, the students are to pick their favorite season and then create a tree with many different materials for that particular season. For spring, we used foam. For summer, we used paint. For fall, we used tissue paper. For winter we used a mixture of paint, cotton balls, and construction paper. I did this with students in preschool all the way through fifth grade. Each student loved the activity and put all their effort into it.
