This program further explores the idea that everything is made of particles by looking at: 1) the difference between atoms and molecules; 2) the difference between elements, compounds and mixtures; 3) how an element like lead can exist in various forms (as an element or in compounds) and how this can affect its properties (e.g. how poisonous it is); 4) why a substance may dissolve in one liquid but not another. We visit a scientific testing laboratory and see discussions with a forensic scientist who discusses arsenic and whether it may have contributed to the death of great racehorse Phar Lap; also we see a case study that looks at the mysterious illness of a family pet, which is traced through scientific analysis to the presence of lead in the backyard soil.
