For the limiting factor I use the "S'Mores" approach. The kids really get into that one..

I, too, use the recipe example...so I can't give much help with a different approach. For limiting reactants, I use the "sandwhich" example. If it takes 2 pieces of bread, 2 piece of cheese and 3 pieces of meat to have a sandwhich, how many sandwiches can you make if you have...(and then give a bunch of examples). Or you can use the brat example (brats come in packages of 5, hot dog buns in packages of 8...what's the limiting reactant). Those two have cleared up limiting reactants for most any student I've explained them to...but that's assuming you've already worked through the "muck" of stoichioemtry to begin with. Maybe somebody will have another idea. Kelly detersk@xxxxxxxxxxxxxx _____ Yahoo! Photos Got holiday prints?
