„Warum tut Haare schneiden nicht weh?“, „Wieso schrumpelt meine Haut beim Baden?“, „Und wie groß ist überhaupt mein Herz?“ - Fragen über Fragen. Wenn Kinder die Welt entdecken, kommen Erwachsene schon mal in Erklärungsnöte. Bei diesen Experimenten ist Neugierde ausdrücklich erwünscht. Die Fragen der Kinder sind der Anstoß, den eigenen Körper einmal ganz genau unter die Lupe zu nehmen. Einfache Versuche geben auf kindgerechte Weise die Antworten. Die Kinder legen Hühnerknochen in Essig ein, bauen eine „künstliche Lunge“ aus Flaschen und Luftballons und basteln eine „Wirbelsäule“ aus Garnrollen. Solche und andere einfallsreiche Hilfsmittel erklären die Funktionen des Körpers schon für die Jüngsten einleuchtend und nachvollziehbar. Mit diesem Buch erwecken Sie den Forscher-Drang Ihrer Kinder - Es ist einen Versuch wert.
