Single replacement lab.
Great, lab. Students see all the signs of reactions. Color change, precipitate formation, gas formed.
Simple lab, and excellent chance to develop lab skills. Rinse everything with distilled water, keep your goggles and glove on.
Put the metals in the test tube and add solutions.
Student, "there's nothing happening."
Lab buddy, "fool, we haven't put the solution in yet."
"Oh."
