Loaded with hands-on, kid-friendly projects, Natural History Collector: Hunt, Discover, Learn! will teach budding nature collectors techniques for cleaning, caring for, and displaying discovered treasures. Coming home from the beach or a walk in the woods with a fine collection of rocks, shells, pine cones, and seed pods is easy. The trick is knowing what to do with them once you get them back to your room. The real fun comes from identifying, preserving, and displaying your treasures! Natural History Collector: Hunt, Discover, Learn! is full of hands-on, kid-friendly projects for the budding naturalist. The opening chapter introduces kids to different ways of creating their personal field guides for keeping track of what they see, when and where they see it, and what makes it interesting. They’ll move on to techniques for cleaning and caringfor treasures, such as drying flowers, pressing leaves, and desalinizing rocks and shells. The book’s drawings and photographs will help kids discover what to look for when they examine feathers, seeds, and minerals (and recognize the difference between sedimentary, igneous, and metamorphic). Extra projects focus on display; making shadow boxes, creating collectors’ cases from egg cartons and candy boxes, labeling, hanging, and mounting collections.

Krone der Schöpfung? Vor 100 000 Jahren war der Homo sapiens noch ein unbedeutendes Tier, das unauffällig in einem abgelegenen Winkel des afrikanischen Kontinents lebte. Unsere Vorfahren teilten sich den Planeten mit mindestens fünf weiteren menschlichen Spezies, und die Rolle, die sie im Ökosystem spielten, war nicht größer als die von Gorillas, Libellen oder Quallen. Vor 70 000 Jahren dann vollzog sich ein mysteriöser und rascher Wandel mit dem Homo sapiens, und es war vor allem die Beschaffenheit seines Gehirns, die ihn zum Herren des Planeten und zum Schrecken des Ökosystems werden ließ. Bis heute hat sich diese Vorherrschaft stetig zugespitzt: Der Mensch hat die Fähigkeit zu schöpferischem und zu zerstörerischem Handeln wie kein anderes Lebewesen. Anschaulich, unterhaltsam und stellenweise hochkomisch zeichnet Yuval Harari die Geschichte des Menschen nach und zeigt alle großen, aber auch alle ambivalenten Momente unserer Menschwerdung.
