And my favorite–have students use stoichiometry to solve a murder mystery in ChemCollective’s program, “Mixed Reception.” The program is free and can be run from a CD. With my class, it took 2 1/2 blocks in our computer lab. Since our lab doesn’t have speakers for every computer, I showed all the videos to the whole group using a projector like the Boxlight. “Mixed Reception” can now be found in a Flash version and run directly from the website. However, the free CD’s are still available.
If you happen to be covering this topic during March Madness, you might want to try “Scooby-doo and the Case of Molarity Mayhem” (doc) with your class. It was contributed by Janine Towle of the NSTA Listserve.
Try Carole Henry’s “S’more Stoichiometry” (doc) worksheet with answers (pdf).
Or have student’s do Karen Belciglio’s “Fun with Moles” (doc) activity.
Do the “Percent Sugar in Bubble Gum” (doc) lab and have students calculate the molar mass of the sugar, convert the mass of the sugar to moles, and determine the number of molecules of sugar in the gum.
Do “The Volume of 1 Mole of Hydrogen Gas” (doc) lab.
Or try “The Determination of Relative Atomic Mass” (doc) lab.
In “The Stoichiometry of Cooking” (pdf) by Lisa Morine, student’s in each group vary the amount of one ingredient for baking cupcakes to see how it affects the final product. Ms Morine includes a teacher’s guide (pdf).
In this “Periodic Table Hopscotch Laboratory” (pdf) students calculate the quantities of chalk used on a sidewalk. It includes a teacher’s guide (pdf).
Try the “Percentage of Water in Popcorn” (doc) lab.
Do this “What’s the Concentration of Kool-Aid?” (doc) lab.
