Context

Science offers us a spectacular perspective of the universe we live in. With its methods and discoveries, we have been able to understand the origin and evolution of the Solar System, a fascinating story that began over 4.6 billion years ago. Studying this subject will allow you, students, to comprehend the forces and phenomena that have shaped our planet Earth and all the celestial bodies that orbit it.

In our Solar System, the Sun is the parent star, and the eight planets, as well as asteroids, comets, and other smaller bodies, form a family that revolves around it. Telling the story of the evolution of the Solar System is describing the dynamics of these elements and how they interact with each other. The matter that makes up our Solar System originated from the dust of stars that existed before the Sun. In this way, we are all made of 'star dust,' an idea that certainly sparks imagination and wonder about our existence.

The evolution of the Solar System is of enormous relevance to our humanity. Understanding the origin of our planetary system allows us to reflect on larger questions such as the origin of life and the probability of the existence of extraterrestrial life. This knowledge is also fundamental for human space exploration, as it allows us to plan space missions and better understand the risks and opportunities associated with space exploration.

Science is a collective effort that develops over time. Each of you will contribute to human knowledge by building a three-dimensional model of the Solar System. In this way, you will develop a deeper understanding of how planets and other celestial bodies interact and evolve over time.

By the end of this project, you will understand the formation and evolution of the solar system and will have improved your teamwork, time management, communication, and creative thinking skills. To assist you in your learning journey, we recommend that you consult the following sources:

Practical Activity: Three-Dimensional Model of the Solar System

Project Objective

The main objective of this activity is to provide a three-dimensional understanding of the Solar System, its main components, its formation, and its evolution over time. Through the construction of a model, students will be able to visualize the spatial and temporal relationships that exist among the celestial bodies that make up the solar system.

Detailed Project Description

This is a group activity that should be carried out by groups of 3 to 5 students. The task is to build a three-dimensional model of the Solar System, representing all eight planets, their orbits around the Sun, and some celestial bodies such as asteroids and comets.

The model should be accompanied by a theoretical explanation of the evolution of the Solar System, from its formation to the present day. The goal is for students to be able to demonstrate a clear understanding of the formation and evolution of the solar system when explaining the model.

Required Materials

1. Styrofoam balls of different sizes and colors (to represent the planets and the sun)
2. Barbecue sticks (to fix and position the planets)
3. Acrylic paint (to paint the planets)
4. Large cardboard box (to serve as the base for the model)
5. Modeling clay (to create relief on the cardboard box)
6. Sequins or glitter (to represent the stars)
7. String (to suspend the planets and mark the orbits)
8. Glue

Detailed Step-by-Step for Carrying Out the Activity

1. Each group starts the activity by researching the components of the Solar System (sun, planets, asteroids, comets, etc.). This should include information such as the relative size of the planets, the distance between them and the sun, and the order of the orbits.
2. Next, students should plan the model, deciding how they will represent each element of the solar system and how they will be positioned in the cardboard box.
3. After that, students should execute their plan, painting the styrofoam balls to represent the planets and the sun, positioning them correctly in the cardboard box, and decorating the 'space' with sequins or glitter to represent the stars.
4. Once the model is completed, each group should prepare a presentation explaining the model and the process of formation and evolution of the Solar System.
5. Finally, each group should write a detailed report on the project, including the justification for the decisions made in the design of the model, the theoretical explanation of the formation and evolution of the Solar System, and a reflection on what they learned throughout the project.

Project Delivery

The project delivery will consist of the three-dimensional model, the oral presentation, and a written report.

The report should follow the following structure: Introduction (contextualization of the theme and project objective), Development (explanation of the theory, detailed description of the activity, methodology used, and results obtained), Conclusion (main points, learning, and conclusions), and Bibliography (sources used).

The report will complement the model and the presentation, describing the research, planning, and execution process of the project, providing details of the theory and decisions made in the model. This will allow students to express in words what they have learned and how they have applied this knowledge in practice.
