Lions and tigers and bears—oh my! During a school trip to the zoo, Maria and Mateo get to see all sorts of interesting animals. But their enjoyment quickly turns to concern. Why are all the animals in enclosed spaces? Wouldn't they rather be free? It seems like it's up to the cousins to rescue the animals! Cousins Maria and Mateo are two curious second graders who love experiencing new things, and their school's field trips are the perfect opportunities to do just that. Join these high-spirited cousins as they learn more about themselves and the world around them through field trips to a zoo, a natural history museum, an orchestra, and a flower farm.
