I.Pre-reading:
There is only one ocean. It’s divided into five different parts: the
Pacific, Atlantic,Indian, Antartic, and Arctic Ocean. There are also many other smaller seas, gulf and bays which form part of them. Altogether they cover 75 percent of the earth’s surface. For centuries, people have challenged by the mysteries that lie beneath the ocean. However, today’s scientists have overcome many of the challenges ofthe depth by using modern devices. They send submarines to investigate the seabed and bring samples of marine life back to the surface for further study. Satellite photographs provide a wide range of information, including water temperature, depth and the undersea populations. If modern technology did not exit, we would never have such precious information.
Marine plants and animals fall into three major groups. Some of them live on or depend on the bottom like the starfish. Some are swimming animals such as fishes and sharks that move independently of water currents while others are tiny organisms that are carried by the currents like the jellyfish . Plants and animals of the sea, however small or oversized, all contribute to its biodiversity. Unless this biodiversity were maintained, marine life would be at stake.
- Work in groups, guess the words hidden from the given pictures and information.
- With a correct answer, your group will get 10 marks.

Sperm whales are the biggest animals on Earth that have teeth. They are carnivores, which means they eat meat. Although sperm whales can be found in all oceans, they prefer the waters with high squid populations, which are their main diet. A sperm whale can eat up to 1,500 kg of food each day. Sperm whales are big animals. The male can grow up to18 meters long and weigh up to 54,000kg while the females are a bit smaller with a length of 12 meters and a weight of 17,000kg. A female sperm whale gives birth to one calf every five to seven years after a gestation period of fourteen to nineteen months. The life span of sperm whales can be up to sixty or seventy years. It is interesting to know that they also have the largest brain of mammals. Sperm whale populations are at risk due to hunting and their accidental entrapment in fishing nets.
Task1: (Work in pairs) Read the description of the sperm whale and then complete the table that follow:
All oceans
Prefer waters with high squid populations
Male: 18 metres in length; 54,000 kg in weight
Female: 12 metres in length; 17,000 kg in weight
Carnivores; eat mainly squid
Give birth to one calf every 5 to 7 years
Gestation period: 14 – 19 months
Up to 60 or 70 years

Task2: Write a paragraph that describes the facts and figures provided in the table. Begin your writing with “ Dolphins are not fish, they are mammals that……..”
EXAMPLE WRITING
Dolphins are not fish, they are mammals that live in the water. Dolphins are among the most intelligent on Earth. Although they can be found in all oceans in the world, dolphins prefer coastal waters and bays. The size of dolphins varies greatly. The smallest dolphin is just about 50kg in weight and 1,2 meters in length while the largest one can weigh up to 8,200 kg and is 10 meters long. Dolphins are carnivores and they eat mostly fish. A female dolphin gives birth to one calf every two years after a gestation period of eleven to twelve months. A dolphin can normally live from twenty-five to sixty-five years and some species of dolphins can even live longer. Dolphin populations at risk due to the population of their habitat and accidental entrapment in fishing nets.`
