Duration: 75 - 85 minutes

This stage aims to deepen the knowledge acquired by students through practical and collaborative activities, using digital resources to make learning more dynamic and connected to modern reality. Furthermore, it promotes the development of critical thinking, analysis, and scientific communication skills.

Activity Suggestions

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

Activity 1 - Diagram Detectives 💡

> Duration: 60 - 70 minutes

- Objective: Identify and analyze an anomalous phase diagram, promoting scientific interpretation skills and collaborative work using digital resources.

- Description: Students will act as scientific detectives on a mission to solve a mystery involving an anomalous phase diagram. Using digital resources such as social media, they will create a report and present their conclusions.

- Instructions:

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

• Provide each group with an anomalous phase diagram (like that of water) and a set of digital clues scattered on an online platform (Google Drive, for example).

• Ask the students to use their cell phones to access the clues. The clues may be in various formats: short videos, social media posts, scientific articles, or even tweets.

• Each group must analyze the clues and discuss among themselves to identify the notable points on the phase diagram and determine the state of matter at various points.

• The groups must create a digital report using a collaborative tool like Google Docs, where they state their conclusions and explain why the diagram is anomalous.

• Request that the groups present their reports in a social media post format (Facebook, Instagram) with hashtags related to the topic #PhaseDiagram #ChemistryClass.

Activity 2 - Science Influencers 🎥

> Duration: 60 - 70 minutes

- Objective: Foster the understanding of phase diagrams and their notable points, developing skills in scientific communication and the use of multimedia tools.

- Description: Students will transform into digital science influencers, creating explanatory videos about the states of matter at different points on the phase diagram.

- Instructions:

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

• Explain that each group will be responsible for creating a short video (2-3 minutes) explaining the notable points of a phase diagram.

• Students should use their cell phones to record videos where they creatively explain what a triple point is, a critical point, and how to identify the state of matter at different points on the diagram.

• Encourage students to use video editing apps (like InShot or Kinemaster) to edit their content, adding images and graphics that assist in the explanation.

• The videos should be posted on a video sharing platform (YouTube or Instagram) with specific class hashtags #ExplainedPhaseDiagrams #FunScience.

• Each group should watch the videos of the other groups and leave constructive comments, promoting an enriching discussion on the subject.

Activity 3 - Interactive Quiz 🔍

> Duration: 60 - 70 minutes

- Objective: Review and consolidate knowledge about phase diagrams in an interactive and engaging manner, using gamification to increase retention of information.

- Description: Students will participate in an interactive quiz using a digital platform (Kahoot or Quizizz) to test their knowledge about phase diagrams and their characteristics.

- Instructions:

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

• Create an interactive quiz on the Kahoot or Quizizz platform, with questions about the notable points of phase diagrams, their properties, and how to identify if a diagram is anomalous.

• Explain the quiz rules and ask students to use their cell phones or computers to participate.

• During the quiz, encourage collaboration within the groups to discuss the answers before submitting them.

• After the quiz, review the correct and incorrect answers, fostering a discussion on the points addressed, allowing students to clarify their doubts.

• Reward the winning group with a digital certificate or a symbolic prize, encouraging healthy competition.

Feedback

Duration: 20 - 25 minutes

🔄 Purpose: This stage aims to consolidate learning through the exchange of experiences and reflections on the activities performed. Through group discussion, students can contextualize the acquired knowledge and improve their communication and critical analysis skills. The 360° feedback promotes self-confidence and personal development, as well as encouraging collaboration and mutual respect among students.

Group Discussion

🔍 Group Discussion: Promote a discussion with all students, where groups share what they learned while performing the activities and their conclusions. Start the discussion with a brief introduction: 'Now that all groups have completed their activities, let's share our experiences and what we learned about phase diagrams. Each group can briefly explain their discoveries and the challenges they faced.' Encourage students to be specific about their observations and analyses.

Reflections

1. 📌 What was the biggest challenge in identifying the notable points in an anomalous phase diagram? 2. 📌 How did the use of digital resources and social media influence the understanding of the content? 3. 📌 In what way did group work help or hinder the completion of the activities?

360° Feedback

💬 360° Feedback: Instruct students to carry out a 360° feedback stage, where each student must receive feedback from their group peers. Guide the class to provide constructive and respectful feedback. Suggest questions like: 'What did your peer do well?', 'What could be improved?', and 'How did your peer contribute to the group?'. Explore ways to offer feedback positively and encouragingly.

Conclusion

Duration: 10 - 15 minutes
