stoichiometry

Students will calculate between moles, mass and number of particles. They will also use one of these values as the starting point denoting the amount of one substance in a balanced equation to calculate the amount of another reactant required or to calculate the amount of product(s) that will be produced.

At our November meeting, Easing your way into CED Unit 4: Low prep, high engagement activities,  we focused on low-prep, high-engagement strategies for AP Chemistry Unit 4 (Chemical Reactions), with an emphasis on helping students build conceptual understanding while preparing for AP-level rigor.
UNO Out Game

I enjoy playing UNO, a popular card game by Mattel, with my family. Students enjoy playing UNO with their friends during lunch or at the end of the day at my school. As a teacher, I have also experienced students having difficulty using dimensional analysis to solve stoichiometry problems. Students have issues with setting up and solving stoichiometry problems.

Stoichiometry often proves to be a challenging topic for high school chemistry students, primarily due to its abstract nature and the reliance on rote memorization for problem-solving techniques rather than a conceptual understanding.

This year, I tried something different with my course progression - instead of doing chemical quantities first and teaching students to convert from grams to mole and then move into stoichiometry, I began with mole to mole stoichiometry and BCA tables.

This is a procedure for a titration experiment suitable for use both at home and in supervised high school or first-year college laboratory settings. Other than an inexpensive pH meter, all materials should be easily available for students to purchase at local stores.
