Technology Integration Workshop 2016 Unit Title: Stoichiometry Grade Level: 10 Subject Area: Chemistry Duration/Length/Number of class periods: 3? weeks of 48ish minute classes Description: Students will learn how to do 1-3 step Stoichiometry problems (mol-mol, mol-gram and vice versa, and gramgram and maybe include volume, atoms, etc) Established Goals (National, State, Local): -

9C.2.1.2.4 Determine the molar mass of a compound from its chemical formula and a table of atomic masses; convert the mass of a molecular substance to moles, number of particles, or volume of gas at standard temperature and pressure.

What Enduring Understandings are desired? That atoms aren’t destroyed, only converted. That matter must be converted in whole number MOLE ratios. That the amount of product that can be created depends on molar ratios and not on the original grams of reactants. What Essential Questions will be considered? Why must atoms be converted, not created or destroyed? Students will know / be able to: - Determine the moles of one chemical in a balanced chemical equation given the moles of another chemical. -

The difference between a mole and a molecule.

-

I can calculate the amounts of products produced if the starting amounts of reactants are known for a chemical reaction.

-

I can calculate the required amount of reactants needed if the desired amount of product is known for a chemical reaction.

-

I can determine the limiting reactant for a reaction.

-

I can determine the excess reactant for a reaction.

-

I can determine percent yield of a chemical reaction.

-

Will know that atoms cannot be created nor destroyed.

-

Will know that atomic ratios must remain constant.

Description - A lot of these would be turned into EdPuzzle videos where I can add questions and track student progress and learning.

You may wish you have a set preprepared with answers if you can’t solve them very quickly. Limiting and Excess Reactant Video (Basic) (Want to make my own)

Materials, tools and resources - My school is a 1:1 device school so they will use those to watch videos and test on. May want a laminator but it's not necessary.
