Contextualization

Hello, dear students! Are you ready to embark on a great adventure through the world of material transformations? Well, to start, it is important to understand what a transformation is. Have you noticed that many things around us change in one way or another? That's what we call transformation! And today, we will focus on the transformations that occur with the materials of our daily lives.

When we talk about material transformations, we are referring to any changes that occur with them, whether in their shape, color, texture, smell, or even in their chemical composition. And these transformations can happen in various ways: by the action of heat, cold, light, water, air, time, and even by the action of other materials.

Importance

Now, you must be wondering, 'Why is it important to learn about the transformations of the materials in our daily lives?' Well, the answer is simple: because everything around us is made of materials, and understanding how they transform helps us better understand the world we live in.

For example, by understanding how ice turns into water when heated, you can better understand the water cycle in nature. By realizing that the clothes you wear shrink when washed with hot water, you are noticing a transformation that occurs with the fabric. Or, by noticing that the apple you left in your backpack for a long time became soft and dark, you are noticing a transformation that happens with the fruit.

Understanding how and why these transformations occur helps us better understand the world around us and allows us to make more conscious decisions. For example, knowing that plastic takes a long time to decompose in nature, you can choose to use less plastic and help preserve the environment.

So, are you ready to embark on this adventure of discovering how the materials of our daily lives transform? Let's go!

Practical Activity

Activity Title: 'Magical Transformations: Exploring Everyday Materials Changes'

Project Objective

The objective of this project is to allow students to explore material transformations, observe, document, and present their findings to the class. Additionally, the activity aims to develop socio-emotional skills such as communication, collaboration, critical thinking, and problem-solving.

Detailed Project Description

In this project, students will form groups of 3 to 5 members to investigate the transformations that occur in three different materials: water, paper, and plastic. Each group will choose one transformation for each material and will carry out a series of experiments to observe, record, and understand these transformations.

Required Materials

• Water
• Ice
• Paper (sheet of sulfite paper)
• Plastic (plastic bag)
• Observation notebook
• Pencil or pen
• Camera (can be a cell phone)
• Internet access for research (under parental or guardian supervision)

Detailed Step-by-Step for Activity Execution

Step 1: Group Formation and Material Selection

Students will form groups and choose the three materials to investigate: water, paper, and plastic. Each group must choose one transformation for each material. For example: for water, a transformation can be from liquid to solid (ice) and from liquid to gaseous (vapor); for paper, a transformation can be from dry to wet and from dry to burnt; for plastic, a transformation can be from cold to hot (melting).

Step 2: Experiment Planning

Each group must plan the experiments to observe the chosen transformations. They should think about how they will conduct the experiment, what materials they will need, and how they will record their observations. Remember, planning is very important for the success of the experiment!

Step 3: Experiment Execution

With the plan ready, it's time to get to work! The groups will carry out the experiments, observe the transformations of the materials, and record their findings.

Step 4: Observation Recording

During the experiments, students must record their observations in the observation notebook and, if possible, take photos or make drawings to illustrate their findings.

Step 5: Results Analysis

After conducting the experiments, the groups must analyze the results, discuss the observed transformations, and try to understand the reasons behind each of them.

Step 6: Presentation Preparation

Finally, the groups will prepare a presentation for the class, in which they will explain the transformations they observed, how they conducted the experiments, what they learned, and what their conclusions were.

Delivery Format

Each group must submit the observation notebook with all notes and drawings, as well as an oral presentation for the class, which can be assisted by visual materials (drawings, photos, etc.) and practical experiments, if possible. In addition, students must also submit a written report, which should contain a description of the experiments, the observations made, the conclusions drawn, and what each one learned from the activity.

Remember, the activity should be done collaboratively, with all group members participating and contributing! Good work, magical transformation adventurers!
