Duration: 60 - 75 minutes

This stage uses Digital Methodology to promote active and engaged learning. The activities are designed to contextualize Coulomb's Law in students' reality, using modern technologies and familiar platforms to make the content more accessible and interesting. The goal is to ensure that students not only understand the theoretical concepts but also can apply them in practical and everyday situations.

Activity Suggestions

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

Activity 1 - 🔌 Digital Experiment: Influencers of Electric Force

> Duration: 60 - 70 minutes

- Objective: Use Coulomb's Law in a practical and creative way, reinforcing the understanding of the concepts through the creation of digital content.

- Description: In this activity, students will become digital influencers on YouTube. They will create a video explaining how Coulomb's Law applies in everyday situations. The video should include practical and creative demonstrations, using easily accessible materials to illustrate concepts of charge, distance, and electric force.

- Instructions:

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

• Each group should choose a spokesperson to act as a 'digital influencer.'

• Students should use their phones to record the video.

• In the video, include an introduction about Coulomb's Law, followed by three different practical examples where the law applies in daily life.

• Examples can include situations like charging by friction, the electric force between small objects, and application in electronic devices.

• Students should edit the video using a simple editing app on the phone or computer.

• The videos should be presented to the class in a 'streaming' session at the end of the activity.

• Students can upload the videos to a video-sharing platform, like YouTube, and share the links with the class.

Activity 2 - ⚡ Gamifying Coulomb's Law: Battle of Charges

> Duration: 60 - 70 minutes

- Objective: Reinforce the understanding of Coulomb's Law through a gamification approach, promoting practical application and critical analysis of the concepts learned.

- Description: In this activity, students will use a physics simulation app to gamify learning. Each group will create a 'battlefield' where different charges interact at various distances. Groups must calculate electric forces and predict the movements of the charges, testing their predictions with the simulation.

- Instructions:

• Form groups of up to 5 students.

• Each group should access a physics simulation app that allows them to input charges and check their interaction (like PhET or another available one).

• Students should set up different charge scenarios (positive and negative) and vary the distances between them.

• Each group should note their predictions about electric forces and the expected movements of the charges.

• Use the app to simulate the different scenarios and analyze whether the predictions were correct.

• Students should calculate the electric force using Coulomb's Law for each scenario before running the simulation.

• Discuss the results found and present to the class, highlighting the concepts learned and any discrepancies found between theory and practice.

Activity 3 - 🌐 Social Media and Coulomb's Law: An Instagram Challenge

> Duration: 60 - 70 minutes

- Objective: Explore Coulomb's Law in a contextualized and accessible way, using the dynamics of social media to promote scientific knowledge.

- Description: Students will create posts on Instagram to explain Coulomb's Law and its applications. They should use popular hashtags and post stories and reels that make the content accessible and interesting for a young audience.

- Instructions:

• Form groups of up to 5 students.

• Each group should create a specific Instagram account for the project or use a shared account provided by the teacher.

• Students should post at least three different content types: a static post with an infographic, a story with a video explanation, and a reel demonstrating a practical application or simple experiment related to electric force.

• Use popular and relevant hashtags to increase the reach of the posts.

• The groups should monitor interactions (likes, comments, and shares) and be ready to respond to audience questions.

• At the end, each group should present an analysis of the reach and impact of their posts and discuss what they learned in the process.

Feedback

Duration: 15 - 20 minutes

The purpose of this stage is to consolidate learning through the sharing of experiences and reflections. The group discussion allows students to articulate their knowledge collaboratively, while the 360° feedback promotes self-criticism and personal growth, preparing students for teamwork and continuous improvement.

Group Discussion

Promote a group discussion with all students, where groups share what they learned while carrying out the activities and their conclusions. Use the following suggested outline to introduce the discussion:

1. Introduction: 🔌 Start by asking each group to briefly summarize their activity and the key learnings.
2. Idea Debate: 💪 Encourage students to reflect on the different ways to apply Coulomb's Law discussed by each group. Ask which approach they found most interesting and why.
3. Connection with Daily Life: 💡 Question how the concepts learned can be observed in everyday situations and in technologies they commonly use, like smartphones and computers.
4. Conclusion: 📝 Conclude by encouraging students to reflect on the importance of understanding Coulomb's Law not just for the Physics subject, but for a broader understanding of the world around them.

Reflections

1. Considering the activities performed, how is Coulomb's Law applied in modern technologies? 2. What was the biggest challenge you faced when trying to apply Coulomb's Law in practice? How did you overcome that challenge? 3. In what way can understanding Coulomb's Law influence your perception of natural phenomena in everyday life?

360° Feedback

Instruct students to conduct a 360° feedback session, where each group member gives and receives feedback from peers. Encourage the class to ensure that the feedback is constructive and respectful, using the 'Feedback Sandwich' methodology (one positive point, one suggestion for improvement, and another positive point). Follow these steps:

1. Preparation: 📃 Explain to students the purpose of the 360° feedback and the importance of being honest and respectful.
2. Individual Feedback: 💬 Each student should speak for about 1-2 minutes, highlighting positive points about their peers' work, providing constructive suggestions, and ending with another positive point.
3. Group Discussion: 👯‍♂️ After individual feedback, promote a brief group discussion so everyone can reflect on the received feedback and how they can improve in future activities.

Conclusion

Duration: 10 - 15 minutes

The purpose of this stage is to reinforce learning in a playful and connected way to students' reality, helping to solidify concepts in a fun and contextualized manner. The creative summary and the discussion about connections to the modern world aim to demonstrate the relevance of the content covered, encouraging students to view Physics differently.
