Main Objectives

1. Understand that a redox equation is one where there is a change in the oxidation number (nox) of substances.

2. Identify and differentiate oxidizing and reducing agents in a redox reaction.

Side Objectives

1. Relate redox reactions to everyday examples, such as the corrosion of metals and biological processes.
2. Develop the ability to use digital tools to analyze chemical reactions.

Introduction

Duration: 10 to 15 minutes

This stage of the lesson plan serves to engage students from the start, encouraging them to connect the topic of redox reactions with their everyday reality through the use of digital tools. By seeking interesting facts and answering key questions, students begin to contextualize the previously studied content, preparing for the practical activities that will follow and creating a collaborative and investigative learning environment.

Warming Up

Introduce the topic of redox reactions by briefly explaining that they are reactions where there is a transfer of electrons between substances, resulting in a variation of the oxidation number (nox). After this brief explanation, ask students to use their cellphones to find an interesting fact about redox reactions, whether related to everyday life, biology, or industrial processes. After a few minutes, ask them to share these facts with the class.

Initial Reflections

1. What is a redox reaction and what are its main characteristics?

2. How can we identify oxidizing and reducing agents in a redox reaction?

3. What are some examples of redox reactions that occur in our daily lives?

4. How are redox reactions important for biological processes, such as cellular respiration?

5. What role do redox reactions play in industrial processes, such as galvanization and energy production?

Development

Duration: 70 to 75 minutes

The purpose of this stage is to provide an environment where students can apply the theoretical concepts of redox reactions in a practical and engaging manner. Using digital tools and modern dynamics, students are encouraged to work in teams, explore creativity, and connect learning to everyday reality, making the educational process more significant and exciting.

Activity Suggestions

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

Activity 1 - Chemical Superhero Stories 隸‍♂️

> Duration: 60 to 70 minutes

- Objective: Relate concepts of redox reactions to everyday situations, identifying oxidizing and reducing agents in a playful way through digital storytelling.

- Description: Students will be divided into groups and must create a story in the format of a social media post where protagonists use redox reactions to solve everyday problems or confront villains. The narrative should clearly illustrate the identification of oxidizing and reducing agents.

- Instructions:

• Form groups of up to 5 students.

• Choose a fictional or real social media platform (Instagram, Twitter, etc.).

• Create a character or superhero that uses knowledge of redox reactions to solve problems.

• Develop a story or post where the character uses a redox reaction.

• Illustrate the story with images or short videos that can be found online or produced, explaining the identification of oxidizing and reducing agents.

• Share the post or story with the class and discuss the solutions presented.

Activity 2 - Gamified Challenge: Redox Treasure Hunt ️‍♀️

> Duration: 60 to 70 minutes

- Objective: Engage students in active and competitive learning where they apply redox equation concepts in a gamified environment.

- Description: Students will participate in a digital treasure hunt where they will find clues in QR codes scattered around the school. Each QR code leads to a challenge involving a redox reaction, which must be solved to advance and reach the final treasure.

- Instructions:

• Form groups of up to 5 students.

• Distribute QR codes in strategic locations around the school.

• The QR codes must lead to online challenges through links or quiz platforms (Kahoot, Socrative, etc.).

• Each challenge must involve identifying oxidizing and reducing agents in different redox reactions.

• Each group must solve the challenges to get the clue to the next QR code.

• The group that completes all the challenges and finds the 'treasure' first wins the game.

Activity 3 - Scientific Digital Influencer 離

> Duration: 60 to 70 minutes

- Objective: Develop scientific communication skills through the creation of digital content, where students are encouraged to teach and learn using modern technologies.

- Description: Students, in groups, will create a video in the style of a 'digital influencer' for a platform like YouTube or TikTok where they explain the importance of redox reactions in everyday life, addressing practical examples and differentiating oxidizing and reducing agents.

- Instructions:

• Form groups of up to 5 students.

• Each group must choose a specific topic related to redox reactions, such as metal corrosion, cellular respiration, or industrial processes.

• Develop a script that clearly and engagingly explains the chosen redox reaction, focusing on the identification of oxidizing and reducing agents.

• Record and edit the video using cellphones and video editing apps.

• Share the video with the class and give a brief presentation explaining their creative process.

Feedback

Duration: 20 to 25 minutes

The purpose of this stage is to promote reflection and consolidation of learning through the sharing of experiences and feedback. This discussion allows students to revisit the concepts covered, recognize their achievements, identify areas for improvement, and value the contributions of their peers, strengthening the sense of community and collaboration in the classroom.

Group Discussion

Promote a group discussion with all students, where groups share what they learned during the experience and their conclusions. Suggest a brief script to introduce this discussion: Start by thanking everyone for their active participation. Ask each group to share their stories, videos, and solutions found during the activities. Encourage the class to ask questions and comment on their peers' presentations. Highlight the strengths and creative aspects of the activities performed.

Reflections

1. What were the biggest challenges your group faced while performing the activities? 2. How do the redox reactions you studied connect with everyday reality? 3. In what way did the use of digital tools help or hinder learning the content?

360° Feedback

Instruct students to carry out a 360° feedback stage, where each student should receive feedback from the other members of their group. Guide the class to ensure that feedback is constructive and respectful, using a 'strengths' and 'areas for improvement' approach. Suggest starting with something positive, followed by a suggestion for improvement. Additionally, each student should share one new thing they learned from a peer during the activities.

Conclusion

Duration: 10 to 15 minutes

 Purpose of the Conclusion 

The purpose of this stage is to recap the concepts covered in a light and engaging way, reinforcing the relevance of redox reactions in students' everyday lives and in the modern world. Furthermore, the conclusion serves to consolidate learning, allowing students to recognize the importance of the studied content and its practical and contextualized application, which encourages a more significant and lasting learning experience.
