RF:
Goal: determine the limiting reagent in a chemical reaction.
1.) Mole Quiz
2.) Paper Clip Mini Lab-Showing limiting reactants.
3.) Vinegar-Baking Soda Demo of limiting reactants. Coach and Model how to find limiting reagent. Practice three problems--> Correct, then computer lab.
4.) Explorelearning gizmo showing molecular representation of limiting reactants.
5.) Work stoichiometry problems, using gizmo sheets from last class. (11-20 in Chap.12)

Monday: Sub: Who killed the electric car?

TR: Goal: Students determine the percent yield of a chemical reaction. Students make stiochiometry calculations. Going around the room solving problems.
1.) Basketball with a trash can analogy for percent yield.
2.) Percent yield problems.
3.) Test Next Class. Test concepts: Stoichiometry Calculation, Limiting Reagents, Percent Yield. Calculations and conceptual problems.

W: Limiting Reactants.

FM: Goal: Stoichiometry Test. Determining amount of products, limiting reactants. After Test:
1.) Phase Changes Gizmo: Determine how the various factors impact the amount of water in the liquid state. Temperature, Altitude, Ice Volume. What is the quickest way to boil all water starting at 0 celsius? What is the quickest way to freeze all of the water starting at 0 celsius.
2.) Making a barometer in a group. Record initial height and weather conditions.
