Objectives (5 - 7 minutes)

1. Introduce the concept of Raw Material: The teacher should define what Raw Material is, explaining that it’s the basis for the production of diverse products that we use everyday. Students should understand that Raw Material is a natural resource found in the earth, in animals or in plants.

2. Explain the concept of Industry: The teacher should explain what an Industry is, explaining that it’s a place where Raw Materials are transformed into products that we use. Students should understand that an Industry is a place where the production process takes place.

3. Establish the relationship between Raw Material and Industry: The teacher should show the students that Raw Material is the main "ingredient" in the production of a product, and that the Industry is where it happens. Students should understand that without Raw Material, there’s no product.

Introduction (10 - 15 minutes)

1. Review of previous content: The teacher should begin the class reminding the students about the concepts of Nature and Environment, highlighting the importance of preserving Nature in order to have Raw Material for the production of our products. This revision can be done through oral questions with the students, encouraging the participation of all.

2. Problem situations: The teacher can propose two situations to introduce the theme of the class. The first one can be: "Have you ever stopped to think about how a pencil is made? Where do the wood and the graphite come from?" The second problem situation can be: "And the clothes that you’re wearing, do you know how they are made and where the materials come from?" The teacher should encourage the students to think about these questions, promoting a brief discussion in class.

3. Contextualization: The teacher, then, should explain to the students that all the things that we use in our daily lives, such as a pencil and a piece of clothing, are made from Raw Materials that come from Nature. The teacher should also explain that in order to transform these Raw Materials into products, we need Industries. The teacher can use simple examples, such as the transformation of milk into cheese, to illustrate the role of Industries.

4. Gaining students’ attention: The teacher can share some interesting facts to get the attention of the students. For example, the teacher can say that to make a simple pair of sneakers more than 30 different types of Raw Materials are required, including rubber, cotton, plastic, glue, etc. The teacher can also mention that the first Industries appeared during the Industrial Revolution, over 250 years ago, and that since then, Industry has become more and more important to our society. The teacher should encourage the students to ask questions and express their curiosity about the theme.

Development (20 - 25 minutes)

The teacher can choose among the following practical activities to develop the students’ understanding about the theme of the class. Each activity should be conducted in a playful and engaging manner, encouraging the active participation of all the students.

1. Raw Materials Memory Game: The teacher can prepare cards with pictures of different Raw Materials (ex: wood, cotton, milk, iron, etc.) and their respective written words. The cards should be placed face down and the students, in pairs, should turn over two cards at a time, trying to match pictures and words. The objective of the game is for the students to identify and memorize the different Raw Materials and the role that each one plays in the production of products that we use in our daily lives. The teacher should walk around the classroom, helping the students and promoting a discussion about the cards that are turned over, reinforcing the connection between the Raw Material and the final product.

2. Creating Class "Industries": The teacher can organize the classroom in different stations, each representing a stage of the production process. For example, a station can be "Collection of Raw Material", where the students will have to "collect" different materials (paper, plastic, fabric, etc.) in a box. Another station can be "Transformation of Raw Material", where the students will have to "transform" the collected materials into a product (ex: drawing on a piece of paper, folding a piece of fabric, etc.). And the last station can be "Final Product", where the students will "sell" the product that they created. The students should go through all the stations, so that they can understand the complete production process. The teacher should explain and guide each step, reinforcing the idea that Raw Material is the basis for the production of a product, and that Industry is where it happens.

3. Puppet Theater - "The Story of the Pencil": The teacher can prepare a simple script about the making of a pencil, from the cutting of the wood to the painting of the graphite. The students will be divided into groups, and each group will be responsible for acting out a part of the production process. The teacher can prepare simple puppets to help with the acting. During the theater, the teacher should pause at each step to discuss with the students what’s happening and how that step connects with the others. In the end, the students should have a clear vision of how the Raw Material is transformed into a final product through the work of the Industry.

The teacher should choose the activity that best fits the dynamics of the class, considering the resources available and the students’ profile. Keep in mind that the main objective is to provide a fun and hands-on experience that will help the students to understand the role of Raw Material and Industry in the production process.

Feedback (8 - 10 minutes)

1. Group Discussion: The teacher should gather all the students in a big circle for a group discussion. Each group should share what they have learned during the activity. The teacher can ask questions to stimulate the discussion, such as: "Which Raw Material did you find most surprising to discover that was needed for the production of a product?", "How did you feel when going through all the steps of the production process?", "What is the importance of Industry for our society?" The teacher should make sure that all the students have the chance to talk, and that the environment is respectful and welcoming to different opinions.

2. Connection with the Theory: Then, the teacher should go back to the theoretical concepts discussed in the beginning of the class, and make the connection to the practical activities. For example, the teacher can ask: "Do you remember when we talked about Raw Material? How do you see its importance now, after going through the activities?" The teacher should reinforce that Raw Material is the starting point for the production of a product, and that the Industry is where this process happens.

3. Individual Reflection: To finalize the class, the teacher should ask the students to reflect for a minute about what they have learned. The teacher can ask two simple questions to guide this reflection: "What surprised me the most about the relationship between Raw Material and Industry?" and "How can I apply what I learned today in my daily life?" The teacher should encourage the students to think deeply about these questions, as they help to consolidate the learning and to relate the contents of the class to real life.

4. Writing Down the Learning: The teacher should finally suggest that the students write down in their notebooks what they learned in the class. They can draw a picture, write a sentence or even create a small story that sums up what they learned. The important thing is that they have the chance to reflect about the learning in an individual way, and express it in a creative manner.

This feedback moment is crucial for the teacher to assess the impact of the class and to identify possible gaps in the students’ understanding. Also, it helps the students to consolidate what they have learned and to understand the relevance of the contents to their daily lives.

Conclusion (5 - 7 minutes)

1. Class Summary: The teacher should start the conclusion by recapping the main points covered during the class. The teacher should remind the students about the definition of Raw Material, the importance of Industries in the process of transforming Raw Material into final products, and the direct relationship between Raw Material and Industry. The teacher can use the blackboard or whiteboard to make this summary, writing the keywords and drawing simple schemes to illustrate the concepts.

2. Connection between Theory, Practice and Applications: Then, the teacher should highlight how the practical activities conducted in class helped to solidify the students’ understanding about the subject. The teacher can explain that by participating in the memory game, by creating the class "Industries" and by performing the puppet theater, the students were able to experience in a playful and concrete way the process of transforming Raw Material into final products. The teacher should also reinforce the importance of the subject in the daily lives of the students, explaining that everything that we use in our daily lives is a result of this process.

3. Suggestion of Complementary Materials: In order to enrich the students’ learning, the teacher can suggest some extra materials for studying at home. This can include children’s books that approach the theme of production in a simplified and fun way, educational videos available on the internet, or even visits to factories or local industries, if possible. The teacher should remind the students that the objective of these materials is to deepen the knowledge acquired in class and to stimulate the curiosity and the interest in the subject.

4. Importance of the Subject for the Daily Life: Finally, the teacher should highlight the relevance of the subject to the students’ daily lives. The teacher can explain that by understanding the production process, the students become more conscious consumers, able to value and respect the work involved in the production of every item that we use. Also, the teacher can mention that the knowledge about Raw Material and Industry is essential for us to understand the importance of environmental preservation and sustainable use of natural resources.

5. End of Class: The teacher should end the class thanking the students for their participation and effort. The teacher can reinforce that curiosity and the will to learn are essential for success at school and in life. The teacher should say goodbye in a warm and welcoming manner, leaving the students excited for the next class.
