Contextualization
Viruses are tiny particles that have the ability to infect living organisms, altering their natural functions, and in many cases, causing diseases. Unlike bacteria and other microorganisms, they are not cells, but rather protein particles that contain genetic material. They are extremely small and can be found in virtually every place on Earth.
The basic structure of a virus consists of a nucleic acid molecule, which can be DNA or RNA, surrounded by a protein coat called a capsid. Some viruses, called enveloped viruses, also have an external lipid envelope. This simple structure makes them highly adaptable, capable of infecting a wide variety of cells.
Viruses reproduce through a process called viral replication. They invade host cells, take control of their functions, and use their machinery to replicate. This is why viruses are often considered obligate intracellular parasites.
In this scenario, understanding viruses and their different manifestations is essential, whether for the role they play in well-known diseases and epidemics worldwide, or for the biotechnological potential they possess. Currently, viruses are the subject of studies ranging from the creation of new vaccines to the genetic modification of organisms.
Viruses not only have a negative impact on our health, they are also useful tools in medical and biological research. For example, scientists have used viruses to manipulate genes in the laboratory, thus creating treatments for some genetic diseases. In addition, some viruses have been used as vectors in gene therapies to treat diseases such as cancer.

Practical Activity
Activity Title: "Design and Development of an Educational Campaign on Viruses"
Project Objective:
- Understand fundamental characteristics of viruses, their structure, and their replication mode.
- Learn about the main viral diseases that affect humanity and their characteristics.
- Produce educational material on viruses and viral diseases based on scientific research.
Project Description:
Students, divided into groups of 3 to 5, will be responsible for creating an educational campaign on viruses. The campaign should address what viruses are, their main characteristics, and the types of viruses. The campaign should also cover the main viral diseases that affect humans.
The campaign should include:
- An informative brochure
- A slide presentation
- An educational video
All content must be original and creative to attract attention and maximize the understanding of the target audience.
Required Materials:
- Computer with internet access for research
- Text editing, presentation, and video editing software (Microsoft Office, Google Drive, or similar)
- Access to libraries and databases for research
Step by Step:
Step 1: Research
Students should start the activity with a detailed research on the proposed topic. They should understand what viruses are, comprehend their structures, and the replication process.
Step 2: Planning
Groups should plan the campaign. This step involves discussing and deciding how to present the information in the brochure, slide presentation, and video.
Step 3: Development
Students should work on creating the campaign content. The brochure should contain concise and clear information; the slide presentation should be visually appealing and informative; the video should be engaging and clearly explain the topic.
Step 4: Review and Finalization
Groups should review all produced material, make necessary corrections, and prepare the material for presentation.
Step 5: Presentation
Each group should present their campaign to the class. Students should be prepared to explain their choices and answer questions about the content.
Project Delivery
After the practical stage, students should produce a project report, which should include:
- Introduction: Contextualizing the theme, its relevance, real-world applications, and the project's objective.
- Development: Explanation of the theory behind viruses, detailing the activities carried out, methodology employed, and discussion of results.
- Conclusion: Recap of the main points, learnings, and conclusions about the project.
- Bibliography: Indication of the sources that supported the project.
The report will be an important record of the construction and development process of the activity and will be evaluated together with the educational campaign.
