Trayectoria de choque: Los asteroides y la Tierra (Collision Course: Asteroids and Earth)

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.
