This activity is designed to give students experience with redox reactions and data processing to determine an activity series for metals based on (simulated) reactions of metals with metal salt solutions. The website used also gives students a Molecular Level look at the process of redox for each single-replacement reaction shown. There are four activities in all. The first three involve placing four metal strips into four ionic solutions and observing a reaction/non-reaction to determine reactivity. The last activity involves (simulated) reactions of various metals with hydrochloric acid. Again, the website gives the students a Molecular Level look at the reactions, with the transfer of electrons being shown. Relative sizes of ions are also indicated, with a detailed description of the reactions. The handout also has a data table/lab handout you can give to students that includes a number of follow-up questions. I have used this to solidify students' understanding of redox and single-replacement reactions along with developing an activity series.
