About Ready-Ed Publications Ready-Ed Publications was established in 1984 with the purpose of creating practical classroom blackline master activities. At the time, the role of the teacher was becoming ever more diverse with an increasing range of duties and responsibilities within the school and school community. Since then, the role of the teacher has continued to evolve with an escalating range of tasks and obligations, ensuring a reduction in time available to prepare work for the daily instructional program.

r o e t s Bo r e p ok u S

Throughout these past 21 years, Ready-Ed Publications has built a reputation as publishers of Australian made, high quality, innovative, timesaving materials for teachers of primary and lower secondary levels. In addition, all materials are based on state or national curriculum guidelines or specific age-related interest areas and subjects.

In 1772, Captain James Cook set off from England in search of a great southern continent.

Some people believe that an American sealer, Captain John Davis, was the first person to walk on Antarctica’s shores at the tip of the Antarctic Peninsula.

The Amazing Race One of the most significant events in Antarctica’s history was the great race to be the first to the South Pole.

ROALD AMUNDSEN (1872 - 1928)

Robert F alcon Scott of the Falcon British Navy, and Roald Engelbrecht Gravning Amundsen Amundsen, an explorer from Norway. The two men never met.

Born in Borge, near Oslo in Norway.

Amundsen and four crew members reached the Pole on 14 December, 1911. He went on to make a number of important discoveries in Antarctica. In 1926, Amundsen made history again by flying over the North Pole in an airship called the Norge.

Born in Devonport, England.

KILLER KRILL?

ew i ev Pr

Teac he r

Krill are tiny prawn-like creatures and are classified as cr ustaceans. crustaceans.

Krill play a very special role in the food chain. Most marine life in this region depend on krill as a staple food. Krill is also fished by several countries that market it as a protein-rich food.

Krill live on phytoplankton which are microscopic plants. During winter the Antarctic region is dark almost all of the time and low light conditions stop the plant process of photosynthesis where plants produce food and energy. This means that the amount of phytoplankton in the water is greatly reduced.

w ww

The Food Chain Krill are found all over the world – not just in Antarctica waters. There are at least 85 species of krill swimming around Antarctica. Krill have a very important role in the food chain as they are a major food source for thousands of marine species.

The fish also have a reduced amount of haemoglobin (heema-glo-bin) in their blood compared to the fish of warmer waters. Haemaglobin is the substance that makes blood appear red. With a reduced amount, the blood is thinner and does not require as much of a fish’s energy to pump it around its body.

Cool Antarctica Crabeater Seals

These seals actually live under the ice that surrounds the Antarctic coast. This keeps them safe from predators such as killer whales and leopard seals that find the region too cold.

These streamlined seals stand out with their dog-like nose.

They feed on krill and have a thick layer of blubber that allows them to exist in the very cool waters of the south.

Their main enemy is the leopard seal and many crabeater seals have the battle scars to prove it!
