Introduction

Duration: 15 to 20 minutes

This stage of the lesson plan aims to activate students' prior knowledge and engage them from the beginning of the class. The objective is to connect the previously studied topic to everyday practice and stimulate them to think critically and creatively about the use of series resistors. Initial interaction through research and discussions also promotes collaborative work and the use of digital tools.

Warming Up

Start the class with a brief introduction to series resistors. Explain that resistors are components that limit electric current in a circuit. When placed in series, their resistances add up, creating a single path for current. Ask students to use their phones to research an interesting fact about resistors or series circuits and share it with the class.

Initial Reflections

1. What does it mean to have resistors in series in an electrical circuit?

2. How does the sum of resistances affect the operation of the circuit?

3. What is the practical importance of understanding series resistors in everyday life?

4. What types of devices or situations use series resistors?

5. What are the possible difficulties encountered when working with series resistors?

Development

Duration: 70 to 75 minutes

This stage of the lesson plan aims to reinforce students' knowledge about series resistors through interactive, contextual, and reality-based digital activities. The activities are designed to promote collaboration, critical thinking, and the practical application of studied concepts, using current tools and technologies to make learning more dynamic and engaging.

Activity Suggestions

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

Activity 1 - Digital Influencers and Electric Circuits

> Duration: 60 to 70 minutes

- Objective: Promote understanding of series resistors in a playful and participative manner, using the appeal of social networks and the digital influencer format to explore and communicate physics concepts.

- Description: In this activity, students will divide into small groups and create a short video, in the style of a digital influencer, explaining how series resistors work. This video will be published on an internal video-sharing platform of the school or a private social network.

- Instructions:

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

• Each group should use their phones to research practical examples of series resistors in everyday life.

• Students must create a script highlighting the theory and practical application of series resistors.

• Using their phones, record a short video (3 to 5 minutes) explaining the concept in a creative and engaging way. Encourage the use of visual aids and animations.

• Publish the video on the chosen platform and share the link with the rest of the class.

• Groups should watch the videos of their peers and leave constructive comments.

Activity 2 - Virtual Escape Room: The Resistor Riddle

> Duration: 60 to 70 minutes

- Objective: Encourage teamwork, critical thinking, and practical application of series resistor concepts in a playful and challenging environment.

- Description: Students will participate in a digital 'escape room' challenge, where they need to solve riddles involving series resistors to advance and 'escape'. Each phase will have a problem to be solved based on the theory studied.

- Instructions:

• Form groups of up to 5 students and distribute a device with internet access to each group.

• Use a pre-configured digital 'escape room' platform with riddles about series resistors.

• Explain that each riddle must be solved to move on to the next phase. The riddles involve calculations and practical applications of series resistor concepts.

• Set a time limit of 60 minutes for students to complete the challenge. The group that finishes first or advances the most phases wins a symbolic prize.

• There will be hints available for each riddle, but their use should be limited to encourage collaboration and problem-solving.

Activity 3 - Gamification: Interactive Quiz with Barcodes

> Duration: 60 to 70 minutes

- Objective: Use gamification to encourage engagement and active learning about series resistors, promoting collaboration and healthy competition among students.

- Description: Students will participate in an interactive quiz competition, where each question is linked to a barcode that they will need to scan with their phones. Each question will address series resistor concepts, and students will accumulate points based on the speed and accuracy of their answers.

- Instructions:

• Organize the class into groups of up to 5 students and give each group a set of barcodes (QR codes) scattered around the classroom.

• Explain that each barcode corresponds to a question about series resistors, which can be accessed through their phones.

• Students should move around the room, scan the barcodes, and collaboratively solve the questions.

• Each correct answer earns points for the group, and the time to complete each question will also be recorded.

• At the end of the defined time (60 minutes), the group with the most points will be the winner.

Feedback

Duration: 20 to 25 minutes

🎯 Purpose: The feedback stage aims to consolidate learning by allowing students to reflect on what they learned and share their experiences and conclusions. The group discussion fosters knowledge exchange and enriches collective understanding of the topic. Additionally, the practice of 360° feedback develops critical skills such as communication, empathy, and self-assessment, creating a collaborative and constructive learning environment.

Group Discussion

🌟 Group Discussion: Start the discussion by asking each group to share their discoveries from the activities. Use the following script to introduce the discussion:

1. Group Presentations: Ask each group to briefly present the activity they carried out (video, escape room, or quiz) and highlight the main conclusions.
2. Guiding Questions: Use open-ended questions to stimulate the exchange of ideas, for example: 'What was the most challenging part?', 'How did you solve the problems that arose?', 'What did you learn about series resistors while doing the activity?'
3. Sharing Experiences: Encourage students to share personal experiences or prior knowledge related to the discussed topic.
4. Collective Conclusions: Ask students to collectively summarize the main learnings from the class and discuss how this knowledge can be applied in real contexts.

Reflections

1. 🔍 Reflection Questions: 2. How did your presentation and explanation help solidify your understanding of series resistors? 3. How did solving the escape room riddles contribute to applying theoretical concepts practically? 4. What were the biggest challenges faced during the quiz competition and how did you overcome them?

360° Feedback

🗣️ 360° Feedback: Explain to students the importance of providing constructive and respectful feedback. Each student should receive feedback from the rest of the group they worked with. Instruct them to follow these guidelines:

1. Positive Aspects: First, focus on the positive points of the colleague, highlighting specific contributions to the activity.
2. Areas for Improvement: Suggest areas where the colleague can improve, always in an encouraging and respectful manner.
3. Appreciation: Conclude the feedback with a positive note or thank them for their collaboration.

Conclusion

Duration: 10 to 15 minutes

🎯 Purpose: 🎯

The conclusion serves to solidify learning, revisiting the main points in a light and fun way, connecting them to the real world and its dynamics. Additionally, it emphasizes the practical importance of the topic, encouraging students to apply their newfound knowledge in everyday situations, promoting a deep and lasting understanding.

Summary

🌟 Summary: The Show of Series Resistors! 🌟

The showcase of series resistors was a success! Imagine that each resistor is a dancer in our physics class and, when combined, they form a complex choreography where the total resistance is the sum of each individual movement. Together, they create a single path for electric current, akin to a continuous soundtrack. Our students demonstrated that they can make this dancing math work, whether by solving riddles or creating viral videos!
