When tanks roared onto the battlefield for the first time in World War I, these mechanical beasts changed how battles were fought and how wars were won. Tanks at War looks at the history of tanks, the always-changing technology of weaponry and armor, and how tactics for the use of tanks in battle have changed from a hundred years ago to modern conflicts today. Read about new technologies in the works for the future including robotic tanks and invisibility cloaking devices.
Wild animals are facing huge challenges in the natural world today. Many are endangered - some critically. This eye-opening book shows how animals are being threatened by habitat loss, climate change, non-native species taking over their habitats, pollution, over-fishing, poaching, collisions with cars and boats, and human diseases. Many recovery efforts are in progress to bring back the populations of some nearly extinct animals and to reintroduce some captive ones to their natural habitats. Readers will learn how scientists are working to save blue iguanas in the Cayman Islands, black-footed ferrets in the Canadian prairies, penguins and albatross in Patagonia, and great apes in Africa. This engaging book also encourages students to compare their life challenges to those of animals in the wild.
This fascinating book, illustrated with colorful photographs, makes the topic of symbiosis easy and fun. It looks at the positive, negative, and neutral effects that result when different kinds of animals interact with each other. Symbiotic relationships highlighted include birds and fish that clean parasites off other animals, bacteria that help keep animals and people healthy, mosquitoes that pass diseases such as malaria, predators that hunt prey, and scavengers that help clean the earth. Other examples of symbiotic relationships include several kinds of animals. Students are asked to illustrate symbiosis in human relationships that are similar to those found in nature.
Foxes, rabbits, mongooses, rats, starlings, turtles, Burmese pythons, and Asian carp are just a few of the invasive animals introduced by people into countries and ecosystems to which they do not belong. This important book describes how these animals are destroying habitats and endangering the lives of native animals, some of which have been brought close to extinction. Students will learn how some arrived accidentally on boats, while others were brought in by people, to be used either as a form of pest control on farms, for hunting or hobbies, or as pets that sometimes get abandoned in the wild by owners. Many native animals, such as raccoons, squirrels, and coyotes have also become invaders in cities, back yards, and homes. Students can research invasive species in their areas and help find ways to stop these wild invaders from taking over the natural habitat.
