Introduction

Duration: (10 - 15 minutes)

The purpose of this stage is to ensure that students understand the fundamentals of classifying carbon chains, an essential skill in Organic Chemistry. This understanding is vital not only for academic success but also for practical application in various fields of the job market, such as chemical and pharmaceutical industries. The development of practical skills and the ability to apply theoretical knowledge to real situations are essential to prepare students for future challenges.

Contextualization

Organic Chemistry is a fascinating branch of chemistry that studies carbon compounds. This area is not only fundamental for understanding the biological and chemical processes occurring around us but also has a direct application in industries such as pharmaceuticals, petrochemicals, and food. For example, the synthesis of new medications, alternative fuels, and even the development of new plastic materials are all practical applications of Organic Chemistry.

Curiosities and Market Connection

離 Curiosities: Organic Chemistry began with the discovery of compounds derived from living organisms, but today it also encompasses synthetic substances. It is interesting to note that in the early 19th century, it was believed that organic compounds could only be produced by living organisms until Friedrich Wöhler synthesized urea in 1828.

 Market Connection: Understanding carbon chains is essential for various industries. In the pharmaceutical industry, for example, the correct classification of chains can be the difference between an effective and an ineffective drug. In the petrochemical industry, classifying the chains aids in producing more efficient and less polluting fuels. Furthermore, in the food industry, Organic Chemistry is crucial for creating preservatives and additives that enhance product quality.

Initial Activity

 Initial Activity: Show a short video (3-4 minutes) that visually demonstrates the difference between types of carbon chains. After the video, pose the provocative question: 'Can you identify which of these compounds are found in everyday products?'. This will encourage students to start thinking about the practical application of what they will learn.

Development

Duration: (40 - 45 minutes)

The purpose of this stage is to consolidate the theoretical knowledge acquired through practical and reflective activities. By building molecular models and solving fixation exercises, students will be able to apply what they have learned in a tangible way, better preparing themselves for future challenges in the job market and developing important skills such as critical analysis, problem-solving, and teamwork.

Covered Topics

1. Classification of carbon chains as open and closed
2. Aromatic chains
3. Homogeneous and heterogeneous chains
4. Branched and normal chains
5. Saturated and unsaturated chains

Reflections on the Theme

Guide students to reflect on how the classification of carbon chains can directly impact the creation of new materials and compounds in the chemical industry. Ask how understanding different structures can aid in the innovation of more efficient and sustainable products, and how these classifications are applied in the development of medications and fuels.

Mini Challenge

Maker Challenge: Building Molecular Models

Students will be divided into groups, and each group will be tasked with building molecular models using craft materials (toothpicks, modeling clay, styrofoam balls, etc.). They must create examples of different types of carbon chains classified during the lesson.

Instructions

1. Divide the class into groups of 4 to 5 students.
2. Distribute building materials (toothpicks, modeling clay, styrofoam balls).
3. Each group must build at least one example of each type of carbon chain (open, closed, aromatic, homogeneous, heterogeneous, branched, normal, saturated, and unsaturated).
4. Ask the groups to present their models to the class, explaining the classification of each constructed model.
5. While groups present, ask questions that encourage reflection on the importance of each type of chain in the industrial context.

Objective: Develop practical skills in building and visualizing molecular models, as well as promote teamwork and the application of theoretical knowledge in a practical context.

Duration: (30 - 35 minutes)

Evaluation Exercises

1. Provide a list of organic compounds and ask students to classify the carbon chains present in these compounds.
2. Propose exercises where students must identify if the chains are open, closed, aromatic, homogeneous, heterogeneous, branched, normal, saturated, or unsaturated.
3. Request that students draw the structures of given organic compounds and classify their carbon chains.

Conclusion

Duration: (10 - 15 minutes)

The purpose of this stage is to consolidate learning, ensuring that students understand the practical relevance of the content addressed. The conclusion provides a space for reflection and discussion, promoting a deeper understanding and the application of theoretical knowledge in real contexts.

Discussion

 Discussion: Facilitate a discussion among students about the knowledge acquired during the lesson. Ask how they felt while building the molecular models and what challenges they faced. Promote reflection on how the classification of carbon chains can be applied in creating new products and solving real problems in the job market. Encourage students to share insights about the importance of carbon chains in their daily lives and future careers.

Summary

 Summary: Recap the main points covered in the lesson, including the classification of carbon chains as open, closed, aromatic, homogeneous, heterogeneous, branched, normal, saturated, and unsaturated. Reinforce the importance of each classification and how they apply to the chemical and pharmaceutical industries.

Closing

 Closing: Explain how the lesson connected theory with practice through interactive activities and maker challenges. Highlight the relevance of the knowledge acquired for the job market and daily life. Emphasize that the ability to classify carbon chains is fundamental for various industries and can lead to significant innovations in products and technologies.
