Lesson Worksheet: Adaptation: Animals Science

In this worksheet, we will practice describing ways in which animals are adapted to their habitats and describing an experiment to investigate how blubber helps animals survive in the cold.


Which animal is best adapted to a desert habitat?

  • A
    Polar Bear isolated on the white background.
  • B
    Green Tree Frog isolated on white background.
  • C
    Arabian Camel isolated on white background


This seal has blubber to keep it warm.

Which of the following is the best description of blubber?

  • AIt is thick fur.
  • BIt keeps animals cool.
  • CIt is a thin layer of fat.
  • DIt is a thick layer of fat.


Fill in the blank: An insulator is a material that heating and cooling.

  • Ablocks
  • Bincreases
  • Cslows down
  • Dstops


Read the passage below and answer the question.

Polar pear

Polar bears live in the Arctic. This habitat is very cold, so it is important for animals to keep warm to survive.

Polar bears have a thick layer of fat called blubber under their skin to keep them warm. Blubber is a good insulator that slows the movement of heat. It helps polar bears keep warm in icy waters.

Animals without enough fat, blubber, or fur will lose too much heat. This may mean that their body temperature will be very low and they will not be able to survive the cold climate. Other animals, such as seals, also have a layer of blubber that helps them keep warm in cold climates.

How does blubber help polar bears survive the cold?

  • AIt helps them to camouflage.
  • BIt cools them down.
  • CIt keeps them warm.
  • DNone of the answers are correct.


Fill in the blank: The arctic fox is adapted for its habitat by having .

White arctic fox

  • Athin white fur
  • Ba hump on its back
  • Cdark-colored fur
  • Dthick white fur


Look at the steps of the blubber experiment.

What is the next step in the investigation?

  • AEmpty the bags.
  • BRepeat the investigation.
  • CTake the temperature of each bag.


The blubber experiment shown is used to investigate how blubber helps animals survive in the cold.

Fill in the blanks: The hand in the shortening bag will , and the hand in the empty bag will .

  • Afeel very cold, not feel cold
  • Bfeel cold, feel warm
  • Cfeel the same, feel warm
  • Dnot feel cold, feel very cold


Consider what this experiment tells us about shortening.

Fill in the blank: Shortening .

  • Ais not an insulator
  • Bhas no effect on temperature
  • Cis a good insulator


Hannah and Michael are discussing how a camel’s hump helps it to survive.

Who is correct?

  • AMichael
  • BNeither
  • CHannah


What does the blubber experiment tell us about how blubber helps animals survive?

  • AIt cools animals down.
  • BIt keeps animals warm.
  • CIt has no effect on temperature.
