• Groups must work together to answer questions and complete the challenges proposed by the game. These challenges may include identifying materials with different photoelectric properties, understanding the relationship between light frequency and electron emission, among others.

• Points are awarded as groups answer the challenges correctly and quickly.

• At the end of the game, the group with the highest score will be recognized as the winner, and the teacher can encourage reflection on the strategies used and the concepts reinforced by the game.

Activity 2 - Physics Influencers: A Post About the Photoelectric Effect 📱✨

> Duration: 60 to 70 minutes.

- Objective: Develop communication and synthesis skills by explaining complex concepts in an accessible and engaging way, while integrating learning with the use of technology and social media.

- Description: In this activity, students will simulate being digital influencers and will create a post or a short video for social media explaining the photoelectric effect. They should do this in a way that is understandable and attractive to a young audience.

- Instructions:

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

• Each group will choose a social media platform (Instagram, TikTok, YouTube, etc.) for which they will create explanatory content about the photoelectric effect.

• Groups must plan and write a script, thinking about how to make the content engaging and easy to understand. They can use memes, analogies, graphics, or any other resource that helps explain the phenomenon.

• Students will record or create their content using their cell phones and, if time and resources permit, may edit the videos with simple editing applications.

• After creating, groups will present their posts or videos to the class, explaining the choices they made and how each element helps clarify the photoelectric effect.

Activity 3 - Virtual Scientific Café: Discussion on the Photoelectric Effect ☕💡

> Duration: 60 to 70 minutes.

- Objective: Promote a deeper and collaborative understanding of the photoelectric effect, encouraging research, critical discussion, and the use of communication technologies.

- Description: Students will participate in a virtual 'Scientific Café' where they will discuss in small groups, using videoconferencing platforms, different aspects and applications of the photoelectric effect. The idea is to simulate an academic debate in a modern and informal setting.

- Instructions:

• Organize students into groups of up to 5 and provide each group with a specific topic related to the photoelectric effect to explore (e.g., Einstein's role, technological applications, etc.).

• Each group should briefly research their topic and prepare discussion points.

• Use a videoconferencing platform (like Zoom or Google Meet) for each group to have 5 to 10 minutes to discuss their topic internally.

• After internal discussion, each group will return to the main meeting to share their findings and insights with the rest of the class.

• At the end, there will be a question and answer session where groups can interact, question, and complement information presented by their peers.

Feedback

Duration: 15 to 20 minutes

✨ Purpose: The purpose of this stage of the lesson plan is to provide an opportunity for students to reflect on what they have learned, share their conclusions, and receive constructive feedback from peers. This reflection and exchange of information help consolidate the knowledge acquired, promote metacognition, and reinforce communication and collaboration skills.

Group Discussion

💬 Group Discussion: Promote a group discussion with all students, where the groups share what they learned while conducting the experience and their conclusions. Use the following script to introduce the discussion:

1. Introduction: Welcome the students and explain that today's activity will be concluded with a group discussion. Reinforce the importance of sharing experiences and learning from classmates.
