Grade: Grade 12
Subject: College Chemistry
Limiting Reagent
- Chemical reaction
- limiting reagent
- excess reagent
- mole ratios

Expected Outcome Of This Lesson Plan-
Curriculum Outcome:
1. qualitative observations of a chemical reaction to identify the chemical changes,
2. presence of limiting reagents, and the products
occurring in a chemical reaction
Teacher Objectives-
At the end of this lesson, students will be able to:
1.predict and observe the limiting and excess reagents in a reaction.
2. distinguish between different substances (reactants and products) based on their changes in colouration.
3. distinguish between limiting and excess reagents in a reaction.
-Lab worksheet
-Various Laboratory Equipment(refer to worksheet)
Teaching Methods-

1. Lesson Introduction-

1.Review previous lesson (mole ratios)
2.Give an example to introduce concept of limiting and excess

2. Lesson Progression-

1.Use the above example to explain in details the concept of limiting and excess reagent
2.Use balanced equations to identify the clues such as left over chemicals and chemicals that reacted completely.

3. Guided Practice-

- Lab activity

4. Student Practice-

- Lab worksheet

5. Learner Accommodations-

1.Direct Instruction
2. Hands on activity
3. Extra time for students with IEP to finish handout
4. More guidelines on lab procedure during activity

6. Assessment-

1. Student understanding will be assessed as I circulate through the class to answer questions about lab
2. Completion of lab worksheet.

7. Lesson Closure-

1.Collect worksheet
Measuring Student Progress-
1.Students will be asked questions on limiting reagent the next day during the lesson
2. Students will be given a quiz at the end of the week on the concept of limiting and excess reactants
