Introduction

Duration: (15 - 20 minutes)

The purpose of this stage of the lesson plan is to spark students' curiosity and interest in the topic, contextualizing the relevance of organic salts in real situations and in the job market. This introduction lays the groundwork for a more engaged and meaningful learning experience throughout the class.

Contextualization

Organic salts are chemical compounds of great importance and are present in various areas of our daily lives. From the manufacture of cleaning products to the production of processed foods, these compounds play a crucial role. Understanding the nomenclature of these salts can help in the development of new technologies and products that we use daily.

Curiosities and Market Connection

 Curiosities and Market Connection:

Food Industry: Many preservatives used in food are organic salts, such as sodium benzoate, which helps preserve the shelf life of products. Cleaning Products: Sodium acetate is used in heating pads and cleaning products. Medicine: Some medications and dietary supplements contain organic salts that play essential roles in the treatment of diseases and in maintaining health.

Initial Activity

 Initial Activity:

Provocative Question: 'Did you know that the same chemical compound can be found in such diverse products as food and cleaning products?' Short Video: Show a 3-4 minute video about the application of organic salts in everyday life and in industry (e.g., 'The Chemistry of Food Preservatives').

Development

Duration: 55 - 60 minutes

The purpose of this stage of the lesson plan is to deepen students' knowledge of the structure and nomenclature of organic salts through practical and reflective activities. By the end of this section, students should be able to correctly identify and name different organic salts and understand their applications in the job market.

Covered Topics

1. Structure of organic salts
2. Nomenclature of organic salts
3. Examples of common organic salts in the industry
4. Practical applications of organic salts in the market

Reflections on the Theme

Guide students to reflect on how the knowledge of organic salt nomenclature can be applied in different sectors of the industry, such as in food production, medicine, and cleaning products. Ask them how they think accuracy in nomenclature can impact the efficacy and safety of these products.

Mini Challenge

Building Organic Salts

Students will build physical models of different organic salts using materials like styrofoam balls and toothpicks to represent atoms and chemical bonds. This activity will help visualize the structure and nomenclature of salts.

Instructions

1. Divide the class into groups of 3-4 students.
2. Provide materials such as styrofoam balls of different colors to represent different atoms (carbon, hydrogen, oxygen, sodium, potassium) and toothpicks to represent the bonds.
3. Distribute cards with different organic salt formulas (e.g., CH3COONa - sodium acetate, C2H5COOK - potassium propanoate).
4. Ask groups to build the models according to the provided formulas.
5. After construction, each group should present their model and explain the nomenclature of the organic salt built.

Objective: Visualize the structure of organic salts and practice nomenclature through a practical activity.

Duration: 35 - 40 minutes

Evaluation Exercises

1. List and name the following organic salts: CH3COONa, C2H5COONa, C3H7COOK.
2. Explain the structural differences between sodium methanoate and potassium propanoate.
3. Provide examples of industrial applications of two of the organic salts listed above.

Conclusion

Duration: (10 - 15 minutes)

The purpose of this stage of the lesson plan is to consolidate students' learning, providing an integrated view of theory and practice regarding organic salts. By promoting reflection and discussion, students will be better able to internalize the knowledge acquired and understand its practical application and relevance in the job market.

Discussion

 Discussion:
