Life Cycles

Animal life cycles can be very different, as seen between the 70-year-old elephants and the adult mayflies that only live a few hours. However, the cuckoo and the cheetah illustrate how many parts are similar, too. Readers will gain a basic understanding of life cycles and as they read about examples from animals all over the world. Colorful photographs of animals in action will engage readers while accessible science content will augment classroom learning.
