The concentration camps, 1933-1945. The Nazis set up their first concentration camp, Dachau, in the wake of Hitlerâs takeover of power in 1933. By the end of the war, 22 main concentration camps were established, together with around 1,200 affiliate camps, Aussenkommandos, and thousands of smaller camps. In 1945, when Allied forces liberated the concentration camps at Dachau, Bergen-Belsen, Buchenwald, Sachsenhausen, Auschwitz and elsewhere, the world was shocked at the sight of images of dead bodies alongside half-dead people in these camps.
Mammals. Mammals (Class: Mammalia) are one of the warm-blooded vertebrates other than the birds. They are the most developed and evolved animals and the Class: Mammalia includes more than 4250 described extant species.
1. Show the class pictures of five very different mammals, such as a cat, kangaroo, horse, rabbit, and monkey. Explain that all these animals are mammals, and that mammals constitute one class of the animal kingdom, which also includes other classes, such as reptiles, birds, and fish. Ask students what these five mammals have in common and mark their responses on a sheet of chart paper.
