Stof er alt, der optager plads i vores univers; vi er lavet af stof og altid omgivet af det. Alt stof er lavet af bittesmå partikler kaldet atomer, som er organiseret i det periodiske system. Følgende aktiviteter vil introducere eleverne til stofs egenskaber og hvordan partikler er arrangeret i hver tilstand.
