Many insects hatch from eggs and molt several times as they grow bigger. Others, such as butterflies, undergo a complete metamorphosis. A common science curriculum topic, insect life cycles may be confusing because of these differences. However, this book breaks down these cycles into easy-to-understand steps in both accessible language and colorful diagrams readers can turn to for review again and again. The most important vocabulary needed to talk about insect life cycles is further explained in fact boxes and an extended glossary.

Frogs and toads are some of the most confusing amphibians to classify. While some of their physical attributes are easy to tell apart, if we take a deeper look at these animals we find it’s not quite that simple. From poisonous skin and bulging eyes to their amazing life cycles, these creatures are as interesting to study as they are difficult to categorize. Once we break down the difference between “true” frogs and “true” toads, it’s easy to see why so many have trouble telling the two creatures apart!
