- Description: Students will be divided into groups of up to 5 people and will need to develop an interactive game using tools like Scratch or any other simple visual programming platform. The game should simulate an electrolysis process, and players will need to calculate the mass deposited on the electrodes using Faraday's Laws to progress in the game.

- Instructions:

• Divide students into groups of up to 5 people.

• Explain that each group must create an interactive game using the Scratch platform or similar.

• Groups should research examples of educational games to better understand the dynamics and possibilities.

• Each group should create a script for the game, where the player will be guided through an electrolysis process.

• The games must include challenges that require calculations using Faraday's Laws to determine the mass deposited on the electrodes.

• Groups should present a preliminary version of the game for feedback from peers and the teacher.

• After making adjustments, each group should share their game with the class, and everyone should play each other's games.

Activity 2 - 📲 Chemical Digital Influencer

> Duration: 60 - 70 minutes

- Objective: Promote understanding of the concepts through the creation of digital content, developing communication skills and the use of technologies.

- Description: Students will create content for an imaginary social media network where they will be digital influencers specialized in chemistry. The goal is to explain Faraday's Laws and how to use them in electrolysis calculations through posts, short videos, and stories. Each group can use video and image editing applications to create the content.

- Instructions:

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

• Each group should choose an imaginary social media network (e.g., ChemGram or ElectroTok) where they will be digital influencers specialized in chemistry.

• Groups must create at least one explanatory post, two short videos, and one sequence of stories about Faraday's Laws and electrolysis calculations.

• Use video editing applications like InShot, Canva or similar to create attractive and informative content.

• Ask groups to share their content on a common platform (like Google Classroom or a class blog).

The investigation will be conducted through an online platform that simulates a laboratory and is aided by videos and digital documents.

- Instructions:

• Form groups of up to 5 students.

• Explain that each group will be a team of detectives that needs to solve a 'chemical crime' in the virtual laboratory.

Summary

🎉 Summary of Electrochemistry: Faraday's Laws 🎉

🌟 Electrochemistry is like an electronic dance! With Faraday's Laws, we can calculate the amount of substance transformed during electrolysis. 🧪✨ The first law states that the mass deposited is proportional to the amount of electric charge passed. The second law relates this mass to the gram equivalent of the ion. Imagine transforming concepts into superpowers to predict chemical reactions! 💡🔋
