Science- Seasons unit idea: looking out the window. Kids trace their hands on to brown paper, stick on to blue paper, which is then stuck on to black cardstock. Decorate the tree hands accordingly. This would make an ideal buddy craft.
Apple Unit from Kindergarten Hoppenings / Great when teaching seasons. Could use balls of tissue paper for each season, and have each student glue one piece onto each tree. so the whole class makes ones poster together
