Lees dit boek en leer hoe zachte en harde materialen van elkaar verschillen.\n\nBoeken in deze serie leren ons de belangrijkste eigenschappen van materialen.  Elk boekje gebruikt eenvoudige woorden om kinderen een basiswoordenschat te leren.  Ook de verduidelijkende foto's dragen bij tot de kennis over dit onderwerp.  In dit deel leggen wij uit hoe iets zacht of hard kan zijn, en welke materialen deze eigenschappen bezitten.",
