Get the students internalizing the present perfect by using it repeatedly while interviewing classmates. Encourage them to go beyond the typical Sí/No with far more interesting responses such as "Definitivamente", "¿Hablas en broma?", and "¡Qué tonterías!"
The vocabulary centers on nature and food but you can edit the sentences so they fit your vocabulary.
Use multiple times by having students do a different question each time.
