Introduction

Duration: (15 - 20 minutes)

The introduction aims to engage students and connect their existing knowledge with the new material to be explored in class. The proposed problem situations will ignite critical thinking and encourage direct application of their knowledge. Contextualizing the Solar System underscores its significance in both scientific exploration and practical applications, preparing students for an engaging learning experience.

Problem-Based Situation

1. What if a new planet is discovered far out in our Solar System? How would this change the orbits and dynamics of the planets we already know?

2. If the Sun were to suddenly vanish, what immediate effects would the planets experience in the Solar System?

Contextualization

The Solar System is a constantly evolving system where celestial bodies interact in intricate ways. Beyond academic interest, understanding the Solar System has real-world implications, such as predicting eclipses and weather patterns on Earth. Making this connection can help students appreciate why studying the Solar System matters and enhance their grasp of the underlying theories and observations.

Development

Duration: (75 - 80 minutes)

The development phase is designed to allow students to creatively apply their previous knowledge about the Solar System in a hands-on manner. Through engaging and challenging activities, this section aims to solidify students' understanding of the characteristics and interactions within the Solar System while developing critical thinking, research, presentation, and modeling skills.

Activity Suggestions

It is recommended that only one of the suggested activities be carried out

Activity 1 - Mission: Unknown Planet

> Duration: (60 - 70 minutes)

- Objective: Enhance research and presentation skills while deepening knowledge about planetary characteristics and the dynamics of the Solar System.

- Description: Students will imagine a new space mission aimed at exploring a recently discovered planet in our Solar System. They will need to prepare a presentation for a space agency that highlights the planet's characteristics, its orbit, composition, and how it compares to the other known planets.

- Instructions:

• Divide the class into groups of up to 5 students.

• Each group will select a 'newly discovered' planet to research (they can create fictional names and characteristics based on current scientific understanding).

• Students should investigate aspects like mass, radius, atmospheric composition, average temperature, and orbit.

• Using visual aids (like slides or posters), each group must create a detailed presentation of their planet, including a section comparing it to other planets in the Solar System.

• Finally, each group will present their findings to the class, allowing classmates to ask questions about the characteristics presented.

Activity 2 - Interplanetary Olympics

> Duration: (60 - 70 minutes)

- Objective: Encourage creative thinking and allow students to apply scientific concepts in a fun, engaging context while learning about the Solar System's conditions.

- Description: In this activity, students will engage in a competition to design a series of sports events that could realistically take place on different planets considering their unique conditions, such as gravity, atmosphere, and temperature.

- Instructions:

• Form groups of up to 5 students.

• Each group is assigned to organize 'Olympics' on a specific planet.

• Students must research the features of their designated planet that would impact sports events (e.g., the gravity on Mars would influence track races).

• Each group should propose at least 3 sports that could be conducted and explain their rules and conditions.

• At the end, groups will present their projects to the class, with their peers voting on the most creative ideas that best aligned with the planet's actual conditions.

Activity 3 - The Great Solar Expansion

> Duration: (60 - 70 minutes)

- Objective: Cultivate forecasting and modeling skills, and deepen understanding of how changes in the Sun impact the planets in the Solar System.

- Description: Students will act as 'solar engineers' tasked with designing an expansion of the Sun, considering a hypothetical increase in its mass and how this would affect the planets in the Solar System.

- Instructions:

• Divide the class into groups of up to 5 students.

• Each group will receive hypothetical data regarding an increase in the Sun's mass and must forecast the consequences for the planets surrounding it.

• Students can use models or simulations to visualize changes in orbits, weather patterns, and living conditions on the planets.

• Each group prepares a presentation outlining their expected consequences for life on Earth and other planets.

• Finally, groups present their findings and predictions to the class.

Feedback

Duration: (15 - 20 minutes)

The feedback phase is crucial for solidifying students’ learning by allowing them to articulate and reflect on the knowledge they’ve gained and the skills they’ve developed. Through group discussions, students have the opportunity to express their understanding, hear diverse perspectives, and assimilate feedback, which contributes to a deeper and more critical comprehension of the Solar System. This stage also evaluates the effectiveness of the activities and the extent to which learning objectives were met.

Group Discussion

At the end of the presentations, hold a group discussion with all students. Begin by asking each group to share one or two surprising or challenging insights they encountered during the activity. Then, motivate students to debate how their discoveries could be applied in practical or scientific contexts concerning the Solar System. Encourage them to reflect on the challenges faced and the creative solutions presented by other groups.

Key Questions

1. What were the biggest challenges you faced while designing the characteristics of an unknown planet or conceptualizing sporting events on other planets?

2. How did the proposals for solar expansion and its effects change your perception of the Solar System and its functioning?

3. In what ways did the presentations alter or reaffirm your existing knowledge about the Solar System?
