Context

In the Chemistry discipline, one of the fundamental areas is the nomenclature of chemical compounds. It is a system that allows for the identification and effective communication about the numerous chemical compounds that exist. The 'Oxides Nomenclature' is a vital part of this system, allowing for the identification of the types of oxides formed through the combination of oxygen with other chemical elements.

Oxides are binary compounds, that is, they are formed by two elements - on one side, we always have oxygen (O), and on the other, we can have any other chemical element from the periodic table. The classification of oxides is based on the element that binds to oxygen, which can be metals or non-metals. They can be basic, acidic, amphoteric, or neutral, depending on the properties of the other element in the chemical bond.

Importance

The nomenclature of oxides, besides being a fundamental topic in Chemistry, has important applications in the real world. They are frequently found in our daily lives, for example in industrial processes, natural phenomena, and in the composition of materials we use daily.

Factors such as air pollution, the greenhouse effect, and the formation of acid rain are linked to the presence of oxides in the atmosphere. In the industry, several oxides are used in the manufacturing of steel, glass, ceramics, fertilizers, and other substances. In the human body, the process of cellular respiration produces carbon dioxide - a type of oxide - which is exhaled by the lungs.

Practical Activity: 'Nomenclature in Action - Identifying Oxides'

Project Objectives

Students should delve into the theory of oxide nomenclature, make connections with everyday life, and practice nomenclature through teamwork. The activity also aims to develop socio-emotional skills, such as teamwork, time management, and problem-solving.

Project Description

Students, in groups of 3 to 5, will conduct intensive research to identify where oxides are present in daily life, such as in industry, home, natural environment, and in the human body itself. The group will select 10 different examples and deepen the research on each one, including the formulation and nomenclature of the oxide, its origin, use, and related health and environmental impacts.

Required Materials

For the project, students will need:

1. Internet access for research.
2. Paper, pen/pencil for notes, and a computer for the final report writing.
3. Program or platform for presentations (PowerPoint, Google Slides, Prezi, etc.).
4. Text editing program (Word, Google Docs, etc.).

Detailed Step-by-Step

1. Team formation: 3 to 5 students per group.
2. Research and selection of oxides: Each group must research and select 10 oxides present in different contexts of daily life.
3. Deepening the research: For each selected oxide, groups must conduct a more detailed research, including: the formulation and nomenclature of the oxide, its origin, use, and impacts on health and the environment.
4. Report writing: Following the proposed format (Introduction, Development, Conclusion, and Bibliography), students must write a report detailing their research and conclusions.
5. Presentation preparation: In addition to the report, groups must prepare a presentation that synthesizes their findings visually and engagingly.

Project Deliverables

Written Report

In the proposed format, with four main sections:

1. Introduction: Explanation about the nomenclature of oxides, its importance, and applicability in daily life.
2. Development: Detailed research, discussion of the methodology used, and the results obtained. Here, students must describe each of the selected oxides, detailing the nomenclature, origin, use, and impacts on health and the environment.
3. Conclusion: Recap of the main findings, reflection on the acquired learning, and how the nomenclature of oxides applies to the real world.
4. Bibliography: Complete references of all information sources used for research and project development.

Presentation

Groups must create a visual presentation, including the main findings of each oxide. The presentation should be engaging and include a balance of visual and textual information. Groups must be prepared to present the work to the class and answer questions about the research.
