Marine Mammals
Whales and Sea Cows
The oceans are the home of whales, which look like fish but, in fact, are mammals like we humans and breathe with their lungs. The film shows the peculiarities of whales, which are divided into two main groups: baleen whales and toothed whales. Baleen whales, among which there is also the blue whale, the biggest of all whales, feed on tiny crustaceans called krill. Toothed whales feed on fish, crabs and other marine animals. One of the best known representatives is the killer whale, which is the fastest marine mammal with a speed of up to 55 km/h. With their leaps they delight the audiences in sea life aquariums. Whether they should be kept like that is a highly controversial issue, however. Whales are also much coveted because of their fat, meat and oil. Having been ruthlessly killed, whales have amost been wiped out and today are subject to international protection. Whale watching boosts people’s interest in these formidable animals. Another threatened animal species lives in the warm and shallow waters of Central America: the sea cows, which feed exclusively on plants and surface for breathing every 2 to 5 minutes. With the extensive accompanying material this DVD is perfectly suited for use in the classroom.

Ceramic
Ceramics are indispensable in our everyday lives. We eat from ceramic plates, drink from ceramic cups, use tiled ceramic bathrooms. But how is ceramic manufactured? The film reveals the secrets of this fascinating material! We get to know more about the beginnings of ceramic in the Old World of Egypt and Mesopotamia, about Greece, China and Rome. We gain interesting insights into the valuable earthenware and are also shown the exquisite further development of the "white gold". Today this versatile material is irreplaceable in industry, too. Whether in space or as an easily compatible substitute in medicine, ceramic is applied in many places.
