Lesson Plan

The document outlines a 40-minute lesson plan on factors affecting the rate of reaction and collision theory for an 11th grade chemistry class. The lesson will begin with an elicitation activity to assess prior knowledge using pictures of sugar dissolving in water at different temperatures. Students will then take a short quiz to further gauge their understanding before the teacher explains key concepts like collision theory and how temperature, concentration, surface area, and catalysts influence reaction rates. To reinforce the material, students will interact with an online reaction simulation. The lesson will conclude with an evaluation of student learning through another short quiz.

Name: Eve Joyce E.

Ablin
Topic/Title Factors Affecting Rate of Reaction and
Collision Theory
Grade Level 11
Time Allotment 40 minutes
Objectives

By the end of the class, we should be able to:


1. summarize the Collision Theory;
2. identify the factors affecting rate of reaction; and
3. explain each factor affecting the rate of reaction.

The class will start with a prayer.

ELICIT (Access prior knowledge)


Time: 2 minutes
The teacher will show a picture to the students about two beakers with water having different
temperatures with sugar inside. The teacher will let the students guess what cup will dissolve the
sugar faster.

ENGAGE (Get the students’ minds focused on the topic(short; question or picture)
Time: 2 minutes
From the previous picture, the teacher will ask the student about the possible factors that affect
the rate of dissolving sugar?

EXPLORE (Provide students with a common experience)


Time: 5 minutes
The teacher will give a short quiz to the student to assess prior knowledge.

Instruction: On a ¼ sheet of paper, write the letter ONLY of the correct answer.

COLUMN 1 COLUMN 2

1. Collision A. sum of all the surfaces on each side of


2. Activation Energy a three-dimensional shape
3. Temperature B. amount of a substance in a defined
4. Surface Area space
5. Concentration C. minimum amount of energy that must
6. Catalyst be provided for compounds to result in
a chemical reaction
D. degree of hotness or coldness
measured on a definite scale
E. a substance that causes or accelerates a
chemical reaction without itself being
affected
F. the sudden, forceful coming together
in direct contact of two bodies

EXPLAIN (Teach the concept. Should include interaction between teacher and students).
Time: 20 minutes
⮚ Discuss the Collision Theory and Factors Affecting Reaction Rate

Key Concepts:

● Collision Theory
○ particles must collide
○ must have sufficient energy
○ have a proper orientation
● Factors Affecting Rate of Reaction
○ Temperature: as the temperature increases, the rate of reaction
increases.
○ Concentration of the reactants: as their concentration increases, the
rate of reaction increases.
○ Particle size: Increasing the surface area of a solid reactant by
increasing the size of particles increases the rate of reaction.
○ Catalyst: Catalysts increase the rate of a reaction without being
changed by the end of the reaction.
ELABORATE (Students apply the information learned in the Explain).
Time: 5 minutes
The teacher will show a simulation of chemical reactions and manipulate various variables for
the student to be able to further understand the lesson.

EVALUATE (How will you know the students have learned the concept?)
Time: 5 minutes
The teacher will give a short quiz for the assessment.

I. Direction: On a 1/4 sheet of paper; choose the letter of the correct answer.

1. Collisions may take place between:


A. Atom
B. Ions
C. Molecules
D. All of these
2. More collisions correspond to a:
A. faster reaction rate
B. slow reaction rate
C. constant reaction rate
D. None of the above
3. What is collision theory?
A. Molecules must collide in the correct orientation with enough energy to bond.
B. Molecules need enough energy to collide and react.
C. Atoms constantly collide and react.
D. The minimum energy needed for atoms to react

II. Enumeration
List four factors that affects the rate of a reaction

EXTEND
Time: 1 minute
Assignment:

The teacher will post the assignment on the google classroom.
