Add small pieces of Li, K, Na to water, with universal indicator if desired, to show relative activities.
Hazards: K forms a peroxide coating that may explode when cut with a knife.
Activities of the Halogens[1][2][3][4]
Displace I, Br from NaI and NaBr solutions with Cl2 (extract halogens into nonpolar solvent like hexane to make them more visible)[5].
Show that I2 does not displace Cl2 from NaCl, etc.
