- Instructions:

• Divide students into groups of up to 5 people.

• Inform students that each group will be a 'digital influencer' that needs to create a 3 to 5-minute video explaining what NOX is and how to calculate it.

• Videos should include practical examples, such as NOX calculations in common compounds.

• Students can use video editors on their phones or computers to add graphic elements and enhance the video quality.

• Encourage groups to use hashtags like #ChemistryExplained, #OxidationNumber, and #NOX to simulate posting on social media.

• After producing the videos, each group should present their work to the class.

Activity 2 - Digital NOX Game: Virtual Escape Room 🔓👾

> Duration: 60 - 70 minutes

- Objective: Apply knowledge about calculating the oxidation number (NOX) in a playful and collaborative context, using an interactive digital game to engage students and develop their problem-solving skills.

- Description: Students will participate in a digital game in the format of an 'escape room,' where they will need to solve puzzles and problems related to calculating the oxidation number (NOX) to 'escape' the virtual environment. They will use cell phones and computers to access the game, collaborating in groups to solve the challenges.

- Instructions:

• Divide students into groups of up to 5 people.

• Provide students with the link to the digital 'escape room' game focused on NOX (previously prepared using an online platform like Google Forms, Kahoot, or a specific educational escape room platform).

• Explain that each group must solve a series of puzzles and problems related to calculating NOX to advance in the game and 'escape' the virtual environment.

• Groups can use digital communication tools, such as chats and video calls, to discuss and solve problems together.

• Monitor the progress of the groups, providing tips and guidance as necessary.

• At the end of the activity, hold a group discussion about the solutions found and the strategies used by the groups.

Activity 3 - Wiki NOX: Creation of a Collaborative Article 📝🌐

- Objective: Collaborate in creating a detailed and comprehensive educational resource on the oxidation number (NOX), developing research skills, technical writing, and teamwork.

- Description: Students will create a collaborative article on a wiki platform or shared online document explaining the concept of oxidation number (NOX) and detailing practical examples. Each group will be responsible for a specific section, and the final article will be a compilation of the work of all groups.

- Instructions:

• Divide students into groups of up to 5 people.

• Explain that each group will be responsible for writing a section of the article about NOX, including definition, rules for calculation, practical examples, and its application in chemical reactions.

• Provide a basic structure of the article and distribute the sections among the groups.

• Students should use their cell phones or computers to access the wiki platform or shared document (for example, Google Docs, Microsoft OneNote).
