Lesson Plan | Active Learning | Scientific Thinking vs. Common Sense

Assumptions: This Active Lesson Plan assumes: a 100-minute class, prior student study with both the Book and the start of Project development, and that only one activity (among the three suggested) will be chosen to be conducted during the class, as each activity is designed to take up a significant portion of the available time.

Objectives

Duration: (5 - 10 minutes)

The Objectives stage is crucial to direct the focus of students and the teacher, clearly establishing what is expected to be achieved by the end of the lesson. By defining clear and specific objectives, students can better guide their prior preparation and participation in class, while the teacher can adjust the activities to ensure that all essential elements are addressed. This section serves as a map for learning, ensuring that both students and the teacher are aligned in terms of goals and expected outcomes.

Main Objectives:

1. Empower students to analyze and differentiate the structure and foundation of scientific thinking in contrast with common sense.

2. Develop the ability to apply critical thinking concepts to evaluate and discuss everyday situations in light of scientific knowledge and common sense.

Side Objectives:

1. Encourage active participation of students through group discussions to promote a deeper understanding of the theme.
2. Foster students' interest in philosophical issues involving everyday life and science.

Introduction

Duration: (15 - 20 minutes)

The Introduction serves to engage students with the theme of the lesson, using problem situations that encourage reflection on the applicability of scientific thinking and common sense in practical contexts. Moreover, by contextualizing the importance of the theme with examples from everyday life and history, students can see the relevance of what they have previously learned and how it applies in real situations, thus increasing their motivation and interest in studying.

Problem-Based Situations

1. Imagine a group of friends discussing whether it is safe to use a cell phone near a gas pump. Some argue that the cell phone can cause explosions due to electromagnetic waves, while others believe this is just an urban myth. How can scientific thinking and common sense help resolve this doubt?

2. After a strong storm, a resident of a rural area claims that the rainwater she collects in a reservoir is purer than the city's tap water. Her neighbor, a chemistry student, contests this claim based on his scientific knowledge. How can these two forms of knowledge, scientific and common sense, clarify this issue?

Contextualization

The ability to discern between scientific thinking and common sense is crucial not only in academic debates but also in everyday situations involving important decisions. Curiosities such as the origin of the myth about the cell phone and gasoline or the story behind beliefs about rainwater can be explored to illustrate how common sense can be influenced by inaccurate or misunderstood information. This section not only prepares students for the practical application of scientific thinking but also sparks their interest through real and relevant examples.

Development

Duration: (70 - 75 minutes)

The Development stage is designed for students to practically and interactively apply the concepts studied regarding the difference between scientific thinking and common sense. Through group activities, they will have the opportunity to explore real and fictional scenarios, debate, investigate, and visualize knowledge in a deeper and playful way. This approach not only solidifies learning but also develops collaboration, communication, and critical thinking skills.

Activity Suggestions

It is recommended to carry out only one of the suggested activities

Activity 1 - Scientist or Detective?

> Duration: (60 - 70 minutes)

- Objective: Develop critical thinking skills and application of the scientific method to solve everyday problems.

- Description: In this activity, students will be divided into groups of up to 5 people. Each group will receive a series of 'mysterious cases' that involve everyday situations where common sense and scientific thinking can collide. Students should use the scientific method to investigate and solve the cases, applying their prior knowledge about the differences between scientific thinking and common sense.

- Instructions:

• Divide the class into groups of no more than 5 students.

• Distribute an envelope containing the 'mysterious cases' to each group.

• Each group must analyze the cases, discuss possible explanations based on common sense and scientific thinking.

• Use available measuring instruments in the room to collect data when necessary.

• Each group must prepare a concluding presentation for each case, explaining their discoveries and the scientific reasoning applied.

• At the end, each group will present their conclusions to the class.

Activity 2 - The Great Debate

> Duration: (60 - 70 minutes)

- Objective: Encourage understanding and argumentation about the effectiveness and applicability of scientific thinking and common sense in various situations.

- Description: Students will participate in a structured debate where they will defend the use of scientific thinking or common sense in certain situations. The central theme will be 'Which is more reliable: scientific thinking or common sense?'

- Instructions:

• Divide the class into two large groups, one representing scientific thinking and the other common sense.

• Each group will have 30 minutes to prepare their arguments based on real and theoretical examples.

• Conduct the debate in two rounds, allowing each side to present their arguments and respond to the other group's questions.

• Use a timer to ensure each side has the same amount of time to speak.

• At the end, promote a vote in the class to decide which side was more convincing.

Activity 3 - Knowledge Mind Map

> Duration: (60 - 70 minutes)

- Objective: Visualize and comprehend the complexity and complementarity between scientific thinking and common sense.

- Description: Students will create a mind map illustrating the interconnection between different concepts addressed in the lesson about scientific thinking and common sense. The map will help visualize how these modes of thinking apply in various situations.

- Instructions:

• Instruct students to draw a large mind map on a piece of paper or on the board, starting with the central division between 'Scientific Thinking' and 'Common Sense'.

• Ask them to identify and connect subcategories and examples of each type of thinking, such as urban myths, scientific theories, and everyday examples.

• Students should use different colors and types of lines to represent types of connections (e.g., causality, mutual influence, contrast).

• Encourage discussion while they build the map so they can justify the connections and learn from each other.

• At the end, each group will present their map to the class, explaining their organization choices and represented relationships.

Feedback

Duration: (15 - 20 minutes)

The purpose of this stage is to consolidate learning by allowing students to articulate what they learned and how they applied scientific thinking and common sense in different contexts. The group discussion helps reinforce the understanding of concepts, allows the exchange of experiences and perspectives among students, and promotes critical reflection on the importance of each type of thinking in practical situations.

Group Discussion

To initiate the group discussion, the teacher should gather all students and propose a reflection on the activities conducted. Each group will have the opportunity to share their main discoveries and challenges faced during the activities. It is important for the teacher to encourage students to discuss how scientific thinking and common sense can be applied together for a better understanding of the world. Suggest that students compare the different approaches and how this influenced their conclusions in the studied cases.

Key Questions

1. What were the most interesting points you discovered when analyzing the 'mysterious cases' through the lens of scientific thinking?

2. How did the use of the scientific method alter or confirm your views based on common sense?

3. Was there any situation where common sense and scientific thinking reached different conclusions? How did you resolve this discrepancy?

Conclusion

Duration: (5 - 10 minutes)

The purpose of the Conclusion is to ensure that students have a clear and consolidated understanding of the topics addressed in the lesson, as well as to comprehend how these concepts are applied in practical situations. This stage also serves to reinforce the relevance of philosophical thinking in everyday life, preparing students to utilize the knowledge acquired in a critical and informed manner.

Summary

To conclude, the teacher should summarize the main points addressed in the lesson, recalling the distinct characteristics of scientific thinking and common sense, as well as the practical activities conducted. It is important to highlight how these concepts are applied in real situations and how the scientific method can help resolve everyday doubts.

Theory Connection

The teacher should emphasize how the lesson connected theory with practice, showing the applicability of the concepts of scientific thinking and common sense in various scenarios. For example, one might discuss how the analysis of urban myths such as that about the cell phone and gasoline can be approached from both common sense and scientific thinking, and how science can validate or refute these beliefs.

Closing

Finally, the teacher should discuss the importance of critical thinking in the students' daily lives, highlighting how the ability to differentiate between common sense and scientific thinking can impact their decisions and worldviews. This discussion helps reinforce the relevance of philosophical content in the development of more conscious and informed citizens.
