2. Identify the uses of different types of fuels in daily life.

Side Objectives

1. Understand the environmental impact of different types of fuels.
2. Explore market trends related to renewable fuels.

Introduction

Duration: (15 - 20 minutes)

This stage aims to introduce students to the topic, sparking their interest and curiosity. By contextualizing the importance of fuels and their applications in the job market, students begin to recognize the relevance of the topic in their lives and the world around them.

Contextualization

Fuels play a vital role in our daily lives. From the moment we wake up and turn on the lights to the transportation we use to go to school or work, fuels are present. They provide the necessary energy for the operation of vehicles, industries, and even cooking our food. Understanding the different types of fuels and their practical applications is essential for us to make conscious and sustainable decisions in the future.

Curiosities and Market Connection

• Did you know that Brazil is one of the world's largest producers of biofuels? The production of ethanol from sugarcane is an example of a renewable fuel that significantly impacts the job market, especially in agriculture and the energy industry.* Currently, there is a growing demand for specialized professionals in renewable energies, such as environmental engineers and biofuel technicians. These careers are in high demand due to the search for more sustainable alternatives to fossil fuels.

Initial Activity

Show a short video (3-4 minutes) that demonstrates the difference between fossil and renewable fuels and their environmental impacts. After the video, pose the following provocative question to the students: "Which type of fuel do you think will be more utilized in the future and why?" Ask them to discuss in pairs for 2-3 minutes and then share their ideas with the class.

Development

Duration: (60 - 70 minutes)

This stage aims to deepen students' knowledge about the different types of fuels and their practical applications through experimental activities and reflective discussions. By applying the knowledge acquired in building a prototype and solving fixation exercises, students will consolidate their understanding and be better prepared to make conscious decisions about energy use in the future.

Covered Topics

1. Fossil Fuels: coal, oil, natural gas
2. Renewable Fuels: biofuels, solar energy, wind energy
3. Environmental impact of different types of fuels
4. Practical applications of fuels in daily life
5. Market trends and sustainability

Reflections on the Theme

Guide the students to reflect on how the choice between fossil and renewable fuels can affect the environment and the economy. Ask the students how they think the use of different types of fuels can influence climate change and what the consequences could be for future generations. Facilitate a discussion on individual and collective responsibilities in the search for more sustainable energy solutions.

Mini Challenge

Building a Solar Cell Prototype

Students will build a simple solar cell prototype using accessible materials. This practical activity will allow students to understand how solar energy can be converted into electrical energy and discuss its applications in daily life.

Instructions

1. Divide the students into groups of 4 to 5 members.
2. Provide the following materials for each group: copper plate, copper sulfate solution, glass plate, copper wires, adhesive tape, small LED light bulb.
3. Ask the students to follow these steps to build the prototype: Cut the copper plate into two equal pieces. Place one of the copper plates in fire until it turns black (copper oxide). Wait for the plate to cool and clean it lightly with a sponge. Place both copper plates inside a glass container, ensuring they do not touch each other. Fill the container with the copper sulfate solution until the plates are submerged. Connect the copper wires to the plates and secure them with adhesive tape. Connect the LED light bulb to the copper wires.
4. Facilitate the discussion on how this solar cell can generate energy and its possible applications in daily life.
5. Ask the groups to present their prototypes to the class and discuss the challenges faced during construction.

Objective: Demonstrate in practice how solar energy can be converted into electrical energy and discuss its applications and benefits as a renewable energy source.

Duration: (35 - 40 minutes)

Evaluation Exercises

1. Explain the difference between fossil and renewable fuels and give examples of each.
2. List three negative environmental impacts caused by the use of fossil fuels.
3. Describe how biofuels are produced and cite two advantages of their use.
4. Research and write a brief paragraph about a current trend or innovation in the renewable fuels market.
5. Discuss how the choice of renewable fuels can influence long-term sustainability.

Conclusion

Duration: (15 - 20 minutes)

This stage aims to consolidate students' learning, ensuring they understand the practical relevance of the content addressed. By summarizing the main points, promoting reflective discussion, and connecting theory and practice, students will gain a clearer view of the importance of renewable and fossil fuels and their daily applications, as well as the individual and collective responsibilities regarding energy sustainability.

Discussion

Promote an open discussion with the students about what they learned in the lesson. Ask about the main differences between fossil and renewable fuels and request examples of each. Encourage students to reflect on how building the solar cell prototype helped them understand the practice of converting solar energy into electrical energy. Discuss the challenges faced during prototype construction and how these skills can be applied in the future. Facilitate a conversation about the importance of choosing more sustainable fuels and how this can impact the environment and the economy. Lead students to think about their individual and collective responsibilities in adopting more sustainable energy practices.

Summary

Recap the main content presented during the lesson, emphasizing the differences between fossil and renewable fuels, their environmental impacts, and their practical applications in daily life. Reinforce the importance of biofuels and other renewable energy sources, such as solar and wind, highlighting market trends and innovations. Remind students of the benefits of using sustainable energy sources, both for the environment and the economy.

Closing

Explain how the lesson connected theory to practice and applications in daily life.
