Students will use manipulatives that represent the ingredients for S'mores (graham crackers, marshmallows, chocolate bar) to determine the limiting and excess reactants (reagents) for making S'mores. The students will extend this to preparing hot dogs for guests at a party and then relate the concept to an actual chemical reaction.This lesson is modified from a lesson by Rick Moog (POGIL project) and in cooperation with Michelle Holdbrooks at Thompson High School.This lesson plan was created as a result of the Girls Engaged in Math and Science University, GEMS-U Project.
