I usually get students to do this lesson after completing a practical investigation into metal properties. Answers to first slide: copper, mercury, tungstem/tungsten, (I know I cheated!) iron and potassium. Mind map to be copied into books. The Passport Control I get students to act out in pairs at the end of the lesson.I usually finish off by showing YouTube clips of exceptions to the rules, such as a cannon ball floating on mercury - a liquid, but still dense.
