4/13/11 Lesson plan: Stoichiometry
Learning objective:
Students should be able to understand that stoichiometric relationships are based on mole
quantities in a balanced equation. Students should be able to use stoichiometry to calculate
mole to mole calculations, mass to mass calculations, mass to volume calculations, mole to
volume calculations, volume to volume calculations, particle to particle calculations and
everything in between.
Procedure:
Give students stoichiometry packet. Follow packet format.
Assess prior knowledge by putting unbalanced reaction on the board.
Al + 02  Al2O3
Balance equation
Perform mole to mole calculation
Mole to mass calculaton
Mass to mass calculation
Draw mole island
Explain 1 mole = 22.4 L of a gas at STP
Define STP as standard temperature and pressure (0 C or 273 K and 1 atm)
1 mole = 6.02 X 10 23 molecules
1 mole = molecular mass for element or compound
Give molecular masses for particular elements.
Evaluation Procedure:
Access knowledge by giving stoichiometry problem set 1 for homework.
Materials:
Stoichimetry packet, Stoichimetry problem set 1.
4/14/11 Lesson plan: Continuation with Stoichimetry.
Objectives:
Students should be able to understand that stoichiometric relationships are based on mole
quantities in a balanced equation. Students should be able to use stoichiometry to calculate
mole to mole calculations, mass to mass calculations, mass to volume calculations, mole to
volume calculations, volume to volume calculations, particle to particle calculations and
everything in between.
Procedure:
Go over homework. (Stoichimetry Problem set 1).
Evaluation Procedure:
Have students guide me through the procedures of each problem on board step by step.
Materials:
Stoichimetry problem set 1.
4/15/11 & 4/18/11 Lesson Plan: Continuation with Stoichimetry
Learning Objective:
Students should be able to understand that stoichiometric relationships are based on mole
quantities in a balanced equation. Students should be able to use stoichiometry to calculate
mole to mole calculations, mass to mass calculations, mass to volume calculations, mole to
volume calculations, volume to volume calculations, particle to particle calculations and
everything in between.
Procedure:
Check for full understanding of Stoichiometry problem set 1. Hand out Stoichimetry problem
set 2. Have students work alone on problem 1 – 8 alone for first half of period. Then pair share
for second half of period. Walk classroom to assure students on the right track and answer
specific questions. On 4/18 students will do the same, but on problem set 9 – 16.
Evaluation Procedure:
Tell Students that problem set 2 will be collected on Tuesday 4/19. Anything not done in class
during these two class periods will be for homework.
Materials:
Stoichiometry problem set 2.
4/19/11 Lesson plan: stoichiometry with limiting reactants
Learning objectives:
Students will be able to identify the limiting reactant in a problem. Students will then be able
to perform stoichimetric problems using the limiting reactant. Students will able to find the
amount of excess reactant left over.
Procedure:
Continue with stoichiometry packet on page 3. Continue to access learning by having students
guide me through parts they should know.
Evaluation procedure:
Homework will be limiting reactant worksheet.
Materials:
Stoichiometry packet, limiting reactant worksheet.
4/20/11 Lesson plan: Stoichiometry and test review.
Learning objective:
Students will be able to identify the limiting reactant in a problem. Students will then be able
to perform stoichimetric problems using the limiting reactant. Students will able to find the
amount of excess reactant left over. Ensure students are aware of the topics that will be
covered on tomorrow’s test.
Procedure:
Go over limiting reactant worksheet that was given for homework. List test topic on board as
follows:
Perfect compostion
Empirical Formula
Molecular Formula
Stoichimetry
Mole to mole relationships
Mass to mass relationships
Limiting reactant
Percent Yield
Take student questions on specific topics then give 1 – 2 examples of each
Conclusion:
Student’s homework will be to study for their exam.
4/22/11 Lesson plan: The Gold Penny Lab
Learning Objective:
Students will understand that a copper penny reacts in the presence of zinc in a sodium
hydroxide solution. Students will next see how it reacts when heated after sitting in this
solution. Students will follow proper lab procedures and safety procedures.
Procedures:
Hand out The Gold Penny Lab sheet.
Go over procedures on worksheet.
Go over safety precautions:
Students are to wear goggles at all times. Warn students if they feel they the NaOH on their
hands they should wash their hands thoroughly. Warn students of obvious safety precautions
with the bunsen burner flame.
Model experiment for students. Have students work in groups of 2 or 3. Observe students to
ensure they are following safety protocol.
Evaluation Procedure:
Have students record their observations after each step on worksheet to hand in.
Materials:
Petri dishes
Hot plate
Zinc Powder
NaOH solution
Bunsen Burner
Crucible tongs
Pennies
