Judith E. Rinard is a freelance writer who worked for more than 20 years as staff writer for National Geographic. She has written extensively - both books and articles - on subjects as diverse as astronauts, whales and dolphins, and ancient cities.
What Happens At the Zoo explores some of the very basic and most well-known animals people may see at a zoo, the types of zoo/park they may be found in and some of the chores that are required to take care of these animals whether it is prepping their meals, teaching them tricks that assist in medical care, washing or providing them with enrichment to name a few and the educative opportunities that are provided by zoos so people may get to know more about the various animals that can be found there. Since the book was published in 1984 it is most definitely outdated to some degree while not every zoo has its own police or can afford to make buildings that mimic Asian temples to house their animals or even have giant pandas or an aquarium so depending on the zoos around you you may have a disappointed child.
Otherwise like other books in this particular series the book is illustrated with brightly colored illustrations that showcase everything being told in the text. As a result children will get a more rounded idea of what is actually occurring in the zoo, especially in places where they may not have access to.
As a result even though it is outdated children who love animals and zoos will find this an enjoyable read as well as an informative one. And it would make for a great starter read before a family visits the zoo to maybe get your child(ren) to think of more questions that can possibly be answered during your visit.
