Sixth graders are studying physical properties of matter. To explore the property of density, students tested different liquids to see which liquids had greater or lesser density than the others. They predicted the order in which they should drop in the liquids and then tested until they determined the correct order by density. The liquids tested were: Ant Saliva, Creepy Cola, Monkey Blood, Vampire Tears and Dragon Juice – just fun names of actual common household substances.
