Student teacher Portfolio

Date : 25/3/2008

Grade : grade 9

Instructor: Rita Breidy

Course : Chemistry

Unit : unit 4 – Organic Chemistry

Topic : Esterification

Content : the ester is a family of organic substances. It is produced by the

esterification reaction, which is a combination between an alcohol

and an organic acid.

Goals : students will be able to:

1. know the structural formula of a primary alcohol

2. know the structural formula of a carboxylic acid

3. compare between an organic acid and a mineral acid

4. understand the definition of the esterification reaction

5. compare between the “Esterification” and the “hydrolyze” reaction

Objectives: After completing this section, the students will state the functional

group of each product (alcohol and acid), and will give its name.

they will identify and write the equation of the esterification reaction

with complete accuracy.

Materials : Chemistry Textbook, Pictures, Worksheets.

Introduction: Chapter 2: Section 2.1 & 2.2 Thinking Critically. Introduce New

Science Terms to students through the use of different molecular

models. Students will listen to the explanation of the teacher.

Teacher will encourage the students to use thinking skills in

discussion and questioning.

Development: Teacher will transfer the molecular models into developed formula

on the blackboard. Students will observe, compare, and discuss

the different formulas to understand the characteristics of the

esterification reaction.

Practice : Students will work in pairs to practice identification of alcohol and

acid, of organic and mineral acids, of esterification and hydrolyze,

using their textbook.

Conclusion:

After planning this lesson, I asked Mrs. Antoinette Abi Nader, a chemistry teacher and a coordinator at Besançon school-Baabda, to critique my work. After reading it, she said that it is a good job, and that I have listed the major procedures which have to be mentioned in a lesson plan, continuing that I can add the prerequisites of this lesson (such as, students must know the aliphatic hydrocarbon). Moreover, she said that I can inform them also, at the end of this lesson, about the lesson that might follow as a result of this one, such as, the “Saponification = Ester + Base”.

According to me, this is the first time that I plan a lesson. I have tried to use the different procedures mentioned in the second chapter of this course “Teaching Planning” as a guide. This experience taught me how to organize my ideas and my knowledge, and how to introduce them to my students in a simple way. Furthermore, I have been guided that I should remember my students at the beginning of a class about the prerequisites before introducing a new topic, in a different way; I should link my new lesson to the previous one.
