• Ask students to record the video using their phones, editing and adding visual elements to make the content more engaging.

• Groups must also create at least one image or infographic that complements the video explanation.

• Each group must post the content on a channel (it can be a fictitious account created for the activity) and share the link with the class and the teacher.

• At the end, each group will present their work to the class, explaining the creation process and the concepts covered.

Activity 2 - Augmented Reality: Exploring Mirrors 🪞✨

> Duration: 60 - 70 minutes

- Objective: Use augmented reality technology to interactively explore the concepts of plane mirrors and image formation, reinforcing theoretical understanding with virtual experiments.

- Description: Students will use augmented reality (AR) apps to explore how plane mirrors work and create interactive simulations. They will be able to visualize image formation at different angles and distances, participating in an immersive experience.

- Instructions:

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

• Each group must download an AR app recommended by the teacher that allows the simulation of plane mirrors.

• Explain how to use the app and its main simulation features.

• Ask students to set up different scenarios in the app, experimenting with how the object's position and the mirror's angle affect image formation.

• Groups must collect screenshots and recordings of the simulations to create a final presentation.

• Each group should prepare an explanation about the simulated scenarios and the observations made during the activity.

• At the end, groups will present their simulations and conclusions to the class, discussing their findings and learnings.

Activity 3 - Gamification: Mirror Challenge 🔍🎮

> Duration: 60 - 70 minutes

- Objective: Apply gamification to make learning about plane mirrors dynamic and engaging, encouraging collaboration and critical thinking.

- Description: Students will participate in a gamified challenge where they will solve problems and riddles related to plane mirrors. Using a gamification platform, they will progress through levels by completing tasks and answering questions about the operation and application of plane mirrors.

- Instructions:

• Divide the class into groups of up to 5 students and choose a gamification platform (like Kahoot, Quizizz, or another that allows the creation of custom challenges).

• Create a set of challenges and questions about plane mirrors, including practical problems, curiosities, and theoretical questions.

• Explain the game rules: each group must complete challenges to level up and accumulate points.

• Ask students to log into the platform and start solving the challenges, checking progress on the results panel in real-time.

• Students can use online resources and their notes to solve the problems, encouraging collaboration and research.

• Each group should record their answers and justifications for the most challenging questions.

• At the end, reveal the winning group and promote a discussion about the issues addressed and the strategies used to solve the challenges.

Feedback

Duration: 10 - 15 minutes

The purpose of this stage is to consolidate learning through collective reflection, allowing students to share their experiences and learnings, as well as promoting the ability to give and receive constructive feedback, essential skills for academic and personal development.

Group Discussion

Promote a group discussion with all students, where each group shares what they learned while carrying out the activities and the conclusions they reached. A suggested outline for introducing this discussion could be:

1. Introduction: Reinforce the importance of the concepts worked on about plane mirrors and how these activities helped to connect theory with practice.
2. Group Presentations: Ask each group to present a brief summary (3-5 minutes) of what they did, what they learned, and their main conclusions.
3. Debate: Open the floor for questions from the class after each presentation. Encourage everyone to participate, questioning the methods used and the conclusions reached by other groups.

How did practical activities help to better understand the concept of plane mirrors compared to theoretical study? 3. How do you believe knowledge about plane mirrors can be applied in real-life situations?

360° Feedback

Conduct a 360° feedback stage, where each student should receive feedback from the members of the group they worked with. Guide the class to ensure that the feedback is constructive and respectful, suggesting positive points and areas for improvement. Explain to students that the goal is to help everyone improve in future collaborative and learning activities.

Some guidelines for feedback:

1. Be Specific: Avoid generalizations. State exactly what you liked and what could be improved.
2. Be Constructive: The goal is to help peers to improve, so feedback should be given positively and respectfully.
