Contextualization

States of matter are a fundamental piece in the science puzzle, helping us understand the world we live in. They are classified into three main categories: solids, liquids, and gases. Each state has unique characteristics and behaviors that make them distinct.

Solids have a defined shape and fixed volume, liquids have a fixed volume but their shape can vary, and gases can change their volume and shape depending on the container they are in. These properties are essential for us to understand the materials and substances that surround us, as well as their interactions.

Introduction

In this project, we will explore in depth the states of matter, their properties and characteristics, how they transform from one to another, and how these transformations are essential for the functioning of our planet and for life as we know it.

We will also conduct practical experiments to test and observe the properties of each state, and how matter can alter its properties when changing states. We will connect these concepts to the principles of thermodynamics and the ideal gas law, expanding our understanding of these phenomena.

Finally, aiming to integrate multidisciplinary learning, this activity will also require students to apply their knowledge of language and textual production, developing research, synthesis, and documentation skills.

Practical Activity

Activity Title: "Exploring the Physical States of Matter: A practical and interpersonal approach"

Project Objective

This project aims to provide students with an in-depth understanding of the states of matter through practical experiments, research, and teamwork cooperation.

Detailed Project Description

Students, in groups of 3 to 5, will carry out a series of activities involving practical and theoretical investigations on the physical states of matter.

1. Theoretical Research

Firstly, the groups must conduct a detailed research addressing the following topics:

• Definition of the solid, liquid, and gaseous states.
• State transformations - melting, evaporation, condensation, sublimation, and deposition.
• Properties of the physical states of matter - density, volume, shape, compressibility, and expansion.
• The relationship between the states of matter and the laws of thermodynamics.

2. Practical Experimentation

The groups will carry out experiments to observe the properties of the states of matter and their transformations. These are:

Experiment 1 - State Transformations: Students must document changes in the state of matter, choosing a substance that can go through all physical states (such as water) and recording its transformations.

Experiment 2 - Properties of the States of Matter: Students choose three substances, one for each state of matter, and perform tests to confirm their properties, such as the compressibility of gas or the incompressibility of solids.

Experiment 3 - Thermodynamics and States of Matter: The groups must conduct experiments to demonstrate the laws of thermodynamics, such as the expansion of a gas when heated.

Required Materials

• Substances for experiments (e.g., water, air balloon, metal cube)
• Heater
• Thermostat
• Volume meters and scale for density measurement
• Computer or tablet with internet access for research and documentation
• Material for video recording (optional)

Step by Step

1. Students must organize themselves into groups of 3 to 5.
2. The groups start with theoretical research, where they will investigate the physical states of matter and their transformations, as well as the relationship with thermodynamics.
3. After the research, the groups will conduct the experiments and document their observations.
4. Upon completing the experiments, each group must share their findings with others and discuss the results.
5. Finally, each group must prepare a report on the project, including an introduction, development, conclusions, and bibliography used.

Project Deliverables

Groups must deliver:

1. Theoretical Research Record: Notes on the research conducted on the physical states of matter, their transformations, and relationship with the laws of thermodynamics.

2. Experiment Documentation: Notes, photos, and even videos on the experiments conducted, including detailed descriptions of each step and observed results.

3. Final Report: Students must use their synthesis and writing skills to prepare a comprehensive final report. This should include an introduction to the topic and why it is important, a detailed development describing the theory and experiments conducted, as well as the conclusions drawn from the results. The bibliography used for theoretical research and report preparation should also be included.

The project estimates a duration of over twelve hours per student, considering both theoretical research and the conduct of experiments and preparation of the final report.
