- Instructions:

• Divide students into groups of no more than 5 people.

• Each group should choose or receive a planet (e.g., Mars, Jupiter, Saturn).

• Students should use their cell phones and computers to research the mass and radius of the designated planet.

• Based on the Law of Universal Gravitation, students must calculate the gravitational acceleration of their planet.

• After performing the calculations, students should create a script for a video, creatively explaining the gravitational acceleration of the planet. They can use video editing apps on their cell phones or computers.

• Encourage the use of visual elements such as graphics, special effects, and even virtual space suits to make the video more interesting.

• The videos should be shared on a video sharing platform (e.g., YouTube) or in a closed social media group, such as Facebook or Instagram, created specifically for the class.

• After creating and posting the video, each group should present their video to the class and answer questions from classmates and the teacher.

Activity 2 - Gamification: Galactic Journey

> Duration: 60 - 70 minutes

- Objective: Stimulate critical thinking and teamwork when solving gravitational acceleration problems in a gamified and interactive environment.

- Description: In this activity, students will participate in a gamified game where they need to solve problems related to gravitational acceleration to advance on an interplanetary journey. Each group will have an avatar and a virtual control panel, and must use technology to calculate the gravitational acceleration of different planets in order to proceed on the journey.

- Instructions:

• Divide students into groups of no more than 5 people.

• Create a virtual gaming environment using a tool like Google Classroom or a gamification platform like Kahoot or Quizizz.

• Each group will receive an avatar and a virtual control panel with the mission to travel through different planets.

• To advance on the journey, students must solve gravitational acceleration problems based on the Law of Universal Gravitation. They will use their cell phones or computers to perform the calculations.

• Each group will be challenged with questions involving calculating gravitational acceleration at different distances from the surface of the planet (e.g., twice the radius of the planet).

• As the groups solve the challenges, they advance in the game and unlock new stages and information about the planets.

• The group that completes the galactic journey with the greatest accuracy and speed will be awarded.

Activity 3 - Virtual Simulation: Gravity in Action

> Duration: 60 - 70 minutes

- Objective: Visualize the effects of gravitational acceleration on different planets and apply the Law of Universal Gravitation to perform precise calculations, using virtual simulations to enrich understanding.

Feedback

Duration: 20 - 25 minutes

🎯 The purpose of this stage is to consolidate learning through the exchange of experiences and reflections, promoting self-awareness and recognition of peers' contributions. The group discussion and 360° feedback are essential for developing communication, collaboration, and mutual respect skills, as well as providing a comprehensive review of the content covered.

Group Discussion

🌍 To begin the group discussion, gather all students and ask each group to share the main learnings obtained during the activities. Ask them to explain the calculations performed, the observations made, and the conclusions drawn about gravitational acceleration on different planets. Use a brief script to introduce the discussion: (1) Ask groups to present their videos or simulation results, (2) Encourage the exchange of ideas about the difficulties faced and how they were overcome, (3) Promote a conversation about how gravitational acceleration influences everyday life and space exploration.

Reflections

1. ❓ How does gravitational acceleration vary between different planets and what factors influence these variations? 2. 📊 What were the main challenges faced when performing calculations and creating digital content? How did you solve them? 3. 🚀 What connections can be made between knowledge about gravitation and modern space technology?

360° Feedback

👍 To conduct the 360° feedback, ask each student to provide feedback to their groupmates about their performance during the activities. Guide the class to give constructive and respectful feedback, mentioning both strengths and areas for improvement. A suggested structure for feedback could be: (1) Make a specific compliment about an important contribution from the peer, (2) Propose a suggestion for improvement, (3) Mention something learned with the help of the peer.

Conclusion

Duration: (10 - 15 minutes)

🎯 Purpose: This final stage aims to consolidate learning in a light and fun manner, reinforcing the connection between the studied content and its practical applications in the real world. Summarizing topics and discussing their implications helps fix knowledge and awaken curiosity about how physics shapes the universe around us, inspiring students to continue exploring and learning.
