Stoichiometry into States of Matter

F: 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.

M: Goal: Students make conversions between pressure units.
1.) Making barometers (initial measurements and conversions).
2.) Test Corrections.
3.) Who killed the electric car?

T: Goal: Stoichiometry Test. Determining amount of products, limiting reactants. After Test: Barometer and inquiry demonstration.

Wednesday and Thursday: States of matter gizmo exploration.
1.) Hot, Medium and Cold colored water demonstration.
2.) Frictionless Ping Pong Ball analogy, and United Streaming Frictionless Magic School Bus video.
3.) Temperature Gizmos 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.
4.) Reading and discussing key points in chapter 13.
5.) Barometer Recording and Calculations.

Friday Monday:
Goal: Students will make heating water and cooling water graphs. (get as many hot plates and water baths as possible.)
1.) Record the temperature every 30 secs to make a heating water graph. Record temperature every 5 minutes to make a cooling water graph.
2.) Have some groups do salt water as their hot and cold water.
3.) Barometer reading and calculations.

Tuesday Wednesday: Solubility of salt at different temperatures. Make a table of mass of salt, temperature of water, and volume of water.
1.) Demo: Salt Volume+water volume addition demonstration.
2.) Salt water solubility temperature graphing.
3.) At different temperatures, students try to make as much water dissolve as possible.
4.) Reading 13.2-13.3
5.) Review kinetic molecular theory and chapter 13 concepts.
