Lesson Plan | Technical Methodology | Materials of Main Everyday Objects

Objectives

Duration: 15 - 20 minutes

The purpose of this stage is to provide students with an in-depth understanding of the materials that make up everyday objects. This is essential for developing practical skills, such as identifying and classifying materials, as well as promoting conscious use and proper disposal, which are valuable skills both academically and in the job market.

Main Objectives

1. Identify the main materials used in everyday life.

2. Understand the origin and classification of materials as natural or artificial.

3. Recognize the importance of conscious use and proper disposal of materials.

Side Objectives

1. Develop the ability to observe and critically analyze everyday objects.
2. Promote environmental awareness from an early age.

Introduction

Duration: (15 - 20 minutes)

The purpose of this stage is to provide students with an initial understanding and spark their interest in the topic, connecting them with real situations and the job market. This creates a foundation for developing the practical and experimental skills that will be worked on throughout the lesson.

Contextualization

The materials we use in our daily lives, such as plastic, glass, metal, and paper, are fundamentally important in our lives. From the water bottle we use to stay hydrated to the toys we play with, all these objects are made from specific materials that have unique characteristics. Understanding where these materials come from and how they are transformed into useful objects can help us value and use our resources more consciously.

Curiosities and Market Connection

Did you know that plastic, one of the most common materials in our daily lives, is derived from petroleum? And that recycling glass can save up to 30% of energy compared to producing new glass? Professionals in various fields, such as materials engineering, product design, and environmental management, work directly with the selection, development, and management of these materials. Knowing these details can open numerous opportunities in the job market, from creating new sustainable products to implementing efficient recycling practices.

Initial Activity

To start the class, show a short 3-minute video that illustrates the manufacturing process of a common object, such as a glass bottle or a plastic toy. After the video, ask the following thought-provoking question to the students: 'Do you know where the material used to make this object comes from?'

Development

Duration: 60 - 70 minutes

The purpose of this stage is to consolidate students' knowledge about everyday materials through practical and reflective activities. This allows students to apply the concepts learned, develop manual and collaborative skills, and understand the importance of conscious use and proper disposal of materials.

Covered Topics

1. Identification of the main materials used in everyday life.
2. Origin of materials: natural and artificial.
3. Conscious use and proper disposal of materials.
4. Environmental impact of materials.
5. Transformation of materials into useful objects.

Reflections on the Theme

Guide the students to reflect on the importance of knowing the materials that make up the objects we use daily. Ask: 'How can knowledge about materials help us make more conscious choices in our everyday lives?'. Facilitate a discussion on how the choice of materials can affect the environment and our quality of life.

Mini Challenge

Building with Everyday Materials

Students will build a simple object using materials found in everyday life, such as paper, plastic, metal, and glass.

Instructions

1. Divide the students into groups of 3 to 4 members.
2. Distribute different materials (paper, plastic, metal, glass) to each group.
3. Ask each group to choose a simple object to build, such as a pen holder, a toy, or a miniature house.
4. Guide the students to discuss and decide which materials are most suitable for each part of the object.
5. Assist the groups during the building process, encouraging collaboration and creativity.
6. At the end, ask each group to present their object and explain why they chose each material and how it can be disposed of properly.

Objective: Develop practical and experimental skills through the construction of objects using everyday materials, promoting collaboration and creativity.

Duration: 40 - 50 minutes

Evaluation Exercises

1. List three materials you use in your daily life and identify whether they are natural or artificial.
2. Describe the proper disposal process for a plastic object.
3. Explain why it is important to use materials consciously.
4. Give an example of how a material can be recycled and transformed into a new object.
5. Draw an object you would like to build and indicate which materials you would use.

Conclusion

Duration: (10 - 15 minutes)

The purpose of this stage is to consolidate students' learning, reinforcing the main points addressed during the lesson and promoting critical reflection on the practical application of acquired knowledge. This ensures that students understand the relevance of the topic for daily life and are better prepared to apply these concepts in real situations.

Discussion

Guide the students to reflect on what they learned during the lesson. Ask: 'What was the most interesting part of the building challenge? How did you feel working in a group?'. Facilitate a discussion that allows students to share their experiences, difficulties, and discoveries. Encourage them to think about how to apply the knowledge acquired in real-life situations and how they can contribute to more conscious use of materials.

Summary

Summarize the main content presented in the lesson: identification of everyday materials, classification into natural and artificial, origin of materials, conscious use and proper disposal, and environmental impact. Reinforce the importance of each of these topics and how they connect with the students' daily lives.

Closing

Explain that today’s lesson connected theory and practice by allowing students to identify materials, understand their origins and impacts, and apply this knowledge in the construction of objects. Reinforce the importance of conscious use and proper disposal of materials for environmental preservation and sustainability. Conclude the lesson by highlighting how the knowledge gained can help students make more informed and responsible choices in their daily lives.
