this experiment involves students observing reaction of metals in water. depending on the materials available to you, several links have been provided for the students to watch to gain results.
it is typical for me to stand at the front of the classroom and perform the experiment for the class as some of the reactions can be dangerous.
analysis questions are included that focus on the hardness and size of the atoms and the reactions observed.

The Periodic Table of Rappers Game
