1. Explain weather patterns and discuss why different places have different frost-free dates.
2. Plant a small garden with some herbs, vegetables, or flowers.
3. Visit a local nursery, greenhouse, or farm. If possible, have the owner explain a typical day during the different seasons.
4. Take a walk through a park. Try to identify the different plants.
5. Visit the library. Use the references there to decide which plants have to be planted after the frost-free date, which can be planted in the early spring, and which can be planted in the fall.
