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.

»Ich bin einer von ungezählten Millionen, die durch Nelson Mandelas Leben inspiriert wurden.« Barack Obama Eine fast drei Jahrzehnte währende Gefängnishaft ließ Nelson Mandela zum Mythos der schwarzen Befreiungsbewegung werden. Kaum ein anderer Politiker unserer Zeit symbolisiert heute in solchem Maße die Friedenshoffnungen der Menschheit und den Gedanken der Aussöhnung aller Rassen wie der ehemalige südafrikanische Präsident und Friedensnobelpreisträger. Auch nach seinem Tod finden seine ungebrochene Charakterstärke und Menschenfreundlichkeit die Bewunderung aller friedenswilligen Menschen auf der Welt. Mandelas Lebensgeschichte ist über die politische Bedeutung hinaus ein spannend zu lesendes, kenntnis- und faktenreiches Dokument menschlicher Entwicklung unter Bedingungen und Fährnissen, vor denen die meisten Menschen innerlich wie äußerlich kapituliert haben dürften.
