Susan Camasta Writes:

We start stoichiometry making S'mores...we do a couple of other simple labs to illustrate the concept and then our discussion and problem solving go in 2 directions: air bags & burning of fossil fuels and CO2 production. This lab comes after discussion and calculation with air bags as the context. See the attachment 42 below.
