In this assessment, you will read a new informational text about animal defense mechanisms. Read the text and look at the diagrams carefully, and answer the questions that follow.Part I: Read “The Great Escape” and look carefully at the diagrams in the article (RI.4.10). Then write a short summary of the article (RI.4.2).“The Great Escape”If you startled a nine-banded armadillo, it might jump straight up into the air and then quickly run away. That response would probably surprise you, as well as unsuspecting predators! Nature has equipped animals with some fascinating ways to meet their survival needs. When faced with hungry predators, many animals will jump, fly, or even run on water to escape.When they feel threatened, springboks jump high in the air and raise the white crest of hair that runs along their backs. They take several consecutive stiff-legged jumps, lifting themselves above the herd. Springboks are wellknown for this odd behavior, called pronking, that seems to serve a number of purposes. From this high vantage point, a pronking springbok can determine the position of predators. Pronking alerts the herd that a predator may be nearby. It also sends a clear message to a predator: “I’m healthy and strong, and you can’t catch me!”Butterfly wings may seem delicate, but they are perfectly designed for fluttering away from a predator. Although it may appear that butterflies have only two wings, they actually have four wings. Two triangular forewings and two hindwings work together so butterflies can move quickly to dodge predators. Their irregular flying behavior makes them hard to catch. This helps them evade predators. Have you ever observed a butterfly being hunted by a bird? Then you know how quickly the butterfly can turn and escape the bird’s beak!The basilisk lizard uses its large feet and great speed to escape predators—by running on top of the water! Basilisk lizards live in trees near ponds and streams. When frightened by a predator, the lizard drops into the water. Basilisk lizards have long toes on their back feet and a fringe of skin that unfurls in the water. Air pockets form under the lizard’s feet. This allows it to run quickly across the surface of the water on its back legs. Startled predators are left far behind! These animals are full of surprises and are built for survival. They have special body parts and behaviors to help them evade predators—on land, in the air, and even in the water. Below, write a short summary of “The Great Escape.” Be sure to clearly state the main idea of the article and include important details (RI.4.2).
