Los ciclos de vida de los peces (Fish Life Cycles)

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.

Fun and lovable illustrations offer encouragement and celebrate dreams for girls who know deep down they have what it takes to achieve anything they want.
