Adaptive features of four animals in polar region

This desert is in the North Pole. Mites, which belong to the spider family, are the commonest land animals. Continent - a large landmass on Earth Climate - the normal weather conditions in a particular area Habitat - the normal environment in which an organism lives Predator - an organism that lives by eating other organisms Prey - an organism that is eaten, or preyed upon Begin the lesson by drawing a three-column chart on the board; each vertical column will represent an animal, and each row will contain a question listed below.

Some get their fill by eating fish with low salt content. After the lesson, ask students to offer their favorite animal and its most interesting features for survival. The home to the many artic creatures is melting due to the global warming.

Motivation Begin with a review or introduction of terms that students will use in this lesson continent, climate, habitat, predator, prey.

Data from the past several decades has shown that polar ice in the North Pole is on the decline, while ice in the South Pole is slightly, but steadily, increasing.

It has 2 tusks which are mainly just a sign of rank, but they also come in handy if Adaptive features of four animals in polar region walrus needs to haul itself out of the water.

Their thick no-neck physiques and loosely interlocked vertebrae make them strong and flexible enough to surf the waves and navigate ice and rocky shores.

The Antarctic Treaty uses the former definition. Arctic circumpolar populations often share more in common with each other than with other populations within their national boundaries.

The ermine, arctic hare, lemming, arctic fox, and arctic ground squirrels change their fur color to a grayish-brown coats for the spring and summer. Choose two animals, and then ask students to speculate. Seals have developed special features to keep them from getting the bends. On land their arch enemy are skuas large birds which snatch penguins chicks from nests.

These sections provide text and video to help students learn about the animal. They used to roam across the cold Gobi in great numbers, but as the human population of the area has grown their numbers have dwindled.

Weddells and other true seals even have extra-big spleens to store red blood cells that are released later during a dive. This keeps the penguins so warm they will actually fluff their feather to released trapped heat in order to cool down. There are also photos of students like them who use the site and talk about habitats.

Like all mammals, seals need water, but you rarely catch them at the company drinking fountain.

Then, during winter, the sun is barely seen between late October and mid-March. The continent of Antarctica is sometimes referred to as a cold desert— a desert is determined not by temperature, but by the average amount of precipitation it receives per year, and since Antarctica gets relatively minimal precipitation each year, it is technically a desert, and a cold one at that.

If a seal runs out of O2, it then converts glucose to lactic acid through a process called glycosis. One of them, which is only 0.

Discuss and compare using the mathematical terms total, most and least. The Inuit gave thanks and respect in turn.

Antarctic Animal Adaptations

Seals have flattened corneas and pupils that can open wide to let in light while swimming. Lead students in a debate over whether or not a selected student's animal could actually adapt and survive. Some animals can live in hot deserts and also in cold deserts, but some have specially adapted to living in the very low temperatures of cold deserts.

And speaking of diving, seals can hold their breath for a very long time… up to two hours for elephant seals. That means a seal can carry a lot more oxygen for its body weight.

On the globe or map, show the class the area of the polar region where these animals live. They all depend, directly or indirectly, on food from the sea.

Development Have students use their Animal Adaptations student esheet to go to Creaturepedia on the Wild Kratts website. This is extremely important, as temperatures in the poles are not warm enough to sustain exothermic animals like insects, amphibians, or reptiles. Ice caps can expand or retract, which explains how ice ages come and go.

This will provide a habitat familiar to the students and allow you to expand on both subjects. At Sea Seals are remarkably adapted to ocean living. This article does not cite any sources. If there was any consolation, it was that the glacial pace of nature would give us decades or even centuries to sort out the problem.

They eat immediately after hibernating. Seasons by the Sun This free article from the NSTA journal Science and Children describes science lessons that incorporate trade books for students in grades K-3 and Fur seals have big, burly shoulders that support equally strong front flippers.

The polar bear (Ursus maritimus) is a large bear which lives in the Arctic. It is also called white bear or northern bear. It has black skin under the white fur.

For four or five months of the year, the daily temperatures in the desert may actually exceed this range, called the range of thermoneutrality. Combined with the scarcity of life-sustaining water, survival for desert animals can become extremely tenuous.

Polar Icecap Biome

As its name suggests, the Arctic fox is a species of fox native to the Arctic region of the world. Also known as the White fox or Snow fox, the Arctic fox is found throughout Alaska. Transcript of Polar Regions - Animal Adaptations Camouflage Many animals in the polar region are white or turn white.

This helps them blend in with all the snow and ice. To expand students’ knowledge of animal features and behaviors that can help or hinder their survival in a particular habitat.

As students approach this Animal Adaptations lesson, bear in mind that, according to research, most lower elementary school students are still forming a basic. Polar ice caps are high-latitude areas completely covered in ice that occur in the polar regions of Earth.

Other planets, Mars for example, have polar ice caps also, but unlike Earth’s ice, which is largely composed of frozen water, Mars’ ice is mostly made up of frozen carbon dioxide.
