Stoichiometry is one of the most difficult topics introduced in chemistry. Adding on limiting reactants only further complicates the topic. But, by having students participate in a simple in-class Skittle activity, they are able to observe hands-on how limiting and excess reactants work, while having delicious fun at the same time!
Students are given a handful of skittles of varying colors. By answering each question using their skittles, students will arrive at a better understanding of limiting reactants and how they play a role in product formation.
A teacher's instruction manual that accompanies the activity can be purchased for only $1! (https://www.teacherspayteachers.com/Product/Stoichiometry-and-Limiting-Reactants-Skittles-Activity-Instruction-Manual-2208325)
