This activity pairs with the book, "Pumpkin Fiesta" by Caryn Yacowitz. I used this activity during a science unit on the 5 needs of a plant. After students learned what plants need in order to grow, I read them the book aloud. Then, students compared what Old Juana KNOWS plants need in order to grow to what Foolish Fernando THINKS plants need. This serves as a good informal assessment to determine if students understand what plants need to grow.
