    Hello!
    I have used the "BLT Sandwich" approach to introduce the concept of stoichiometry to my students. First, we list all of the ingredients and amounts of each on the board. Then I ask questions like, "how many sandwiches could we make if we have 47 slices of bacon?" We work out the solution with unit analysis (stoich), even if the problem could be solved mentally. I want them to see that stoich can be used for all kinds of practical problem-solving.
    This video impressed the importance of using everyday household chemicals in labs. Long fancy-named chemicals often have no meaning to these kids, whereas they'll remember distilling cherry coke much longer!
