Use the season you actually have
US climates differ, and not every winter has snow or every fall has colorful leaves. Let local conditions guide outdoor plans and keep an indoor version available. The point is noticing, not recreating a seasonal photograph.
Before starting, check the materials and adult-help notes in the guide. Begin with a small version and keep a familiar alternative available. If the idea does not fit the day, simplify the task or choose a different pace; a longer list is not always the answer.
