Have teams come up with a team name. 2. Provide brief instructions prior to each event and indicate how you want teams to let you know when they've completed the event. • Event #1 (quiz)—As a team answer the questions (have one student per team record answers on paper—make sure the paper has team name, number or some other identification). • Event #2 (measuring a mole of zinc)—This will be a relay, with each student adding a spoonful of zinc to the filter paper or weighing boat until they have 1 mole of zinc. (You can decide whether to remind them to take into account the filter paper or weighing boat or if you want them to think of it on their own.) When they have obtained 1 mole of zinc they are to place it into a zip lock bag which they should label with team name and the mass of the enclosed zinc. • Event #3 (determining which sample contains 0.5 moles of sulfur)—When students have determined which sample it is they are to write the letter of the sample on the index card along with their team name. 3. Optional—Take photos of each team (with mole mascot if you have one). 4. Tally scores, announce winners and award prizes! (I announce winners the next day.)
