Contextualization

Hello, future scientists! We are about to embark on a journey of discoveries and learning. Have you ever stopped to think about how we perceive the world around us? One of the most important ways is through light! It is essential for our vision, but light is not just for seeing - it also has many characteristics and curious interactions with the world around us. In our project, we will explore the 'Passage of Light through Objects'.

Light is everywhere, from the sunlight that brightens our day to the small lamp that allows us to read at night. But did you know that not all objects interact with light in the same way? Some objects let light pass through, others reflect it, and some even absorb it! This affects how we perceive things and how they appear to us, and that's what we will explore more deeply in this project.

Introduction

Within the vast field of science, there are many concepts related to light and how it interacts with objects. Some important questions we will be examining include: What is light? How does light behave when it hits an object? What types of materials allow the passage of light and which do not? And finally, how does the light that passes through or reflects from objects affect the way we perceive the objects?

To answer these questions, we need to understand key concepts such as reflection (light reflects off an object), absorption (light is absorbed by an object), and transmission (light passes through an object). Each of these phenomena has specific characteristics and effects, which we will see throughout our study.

But our journey does not end there! In addition to learning about science, we are also here to develop essential life skills such as cooperation, problem-solving, and creativity. For this, we will work in small groups and carry out practical experiments, learning and discovering together. Keep in mind that, on this journey, each of you is a crucial explorer in uncovering the secrets of light.

So, are you ready to begin? Grab your notebook, ignite your curiosity, and let's embark on this fascinating adventure with light!

Practical Activity

Activity Title: Exploring Light and Objects

Project Objective

The objective of this project is to allow students to explore and understand how light interacts with different materials and objects. Through a series of practical experiments, students will have the opportunity to see how light is reflected, absorbed, or transmitted by different types of objects.

Detailed Project Description

This project will be carried out in groups of 3 to 5 students. Each group will be responsible for conducting a series of experiments and observations, and then reporting their findings. Each experiment will focus on a specific type of interaction between light and the object: reflection, absorption, or transmission.

Based on the observations and experiments, each group will create a logbook where they will document all their discoveries and observations.

Required Materials

1. Three types of materials:
   • Transparent object (Ex: piece of transparent plastic or glass)
   • Translucent object (Ex: parchment paper or thin fabric)
   • Opaque object (Ex: cardboard or wood)
2. Flashlight
3. Paper and pencil to make the logbook
4. Camera or cellphone to document the experiment (optional)

Detailed Step-by-Step for Activity Execution

1. Preparation: Divide into groups and gather the necessary materials. Make sure each group has a flashlight and the three types of objects.
2. Reflection Experiment: Take the opaque object and shine the flashlight on it. Observe how the light is reflected back and does not pass through the object. Notice how this affects the appearance of the object.
3. Absorption Experiment: Now, take a black object and shine the light on it. Observe how it seems to absorb the light and does not reflect as much as the normal opaque object.
4. Transmission Experiment: Next, take a transparent object and a translucent object. Shine the flashlight on each of them and observe how the light passes through them. Notice the difference between the transparent object (where the light passes completely) and the translucent object (where the light passes, but not completely).
5. Logbook: Document all experiments, observations, and findings in the logbook. Try to explain why you think light behaves differently with different types of objects.
6. Presentation of Findings: At the end of the project, each group will present their findings to the class. This is a chance to share what you have learned and discuss your ideas.

Remember, the most important thing about this project is to explore, discover, and have fun learning! Good luck, young scientists!
