Animal talk Animals do not talk like people, but they still communicate with each other. For example, birds sing and chirp, dogs bark, cats meow and lions roar. The blue whale is not only the largest animal on Earth, but also the loudest. Blue whales emit very loud and repetitive sounds that travel many kilometres underwater. The call of a blue whale can reach up to 188 decibels. This is much louder than a jet engine, which is about 140 decibels. Human shouting is 70 decibels. Sounds over 120 decibels are painful to our ears.

Read and write T (true) or F (false). Then, correct the false sentences. a. Blue whales are the largest and loudest animals on Earth. b. Their sounds can be heard from very far away. c. A decibel is a unit for measuring distance. d. The sound of a jet engine is louder than the call of a blue whale. e. Blue whale sounds can be painful to our ears.

How animals protect themselves from the cold During the winter, the days get shorter and the temperatures drop. So, animals need to protect themselves from the cold. Some animals, such as rabbits, dogs, cats and polar bears, grow thicker fur to keep themselves warm. Some animals hibernate. This means they sleep during the coldest months of the year. For example, squirrels, bears, turtles, bats and frogs hibernate and sleep all winter. Some animals migrate. This means they travel long distances to find warmer climates. For example, storks, antelopes, whales, swallows and ducks migrate.
