Activity Suggestions

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

Activity 1 -  Mixture Detectives

> Duration: 60 - 70 minutes

- Objective: Apply knowledge about separation of mixtures in a practical and engaging context, using technology to simulate chemical experiments.

- Description: In this activity, students will become chemical detectives who need to solve an intriguing case involving different mixtures. Using their phones and computers, they will receive digital clues and conduct virtual experiments to discover how to separate the mixtures found at the crime scene.

- Instructions:

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

• Explain that each group is a team of detectives and they must solve a case of water contamination in a lake.

• Distribute a digital document containing the case and information about the mixtures present (e.g., oil in water, sand in water, salt in water).

• Students should use laboratory simulation apps (such as PhET Interactive Simulations) to test different methods of separating mixtures: decantation, filtration, and distillation.

• Each group must document their findings and create a digital presentation (using tools like Google Slides) explaining which separation method was most effective for each mixture and why.

• The groups will share their presentations with each other and discuss their conclusions.

Activity 2 -  Chemical Influencers

> Duration: 60 - 70 minutes

- Objective: Encourage creativity and communication skills of students by explaining scientific concepts in a modern and accessible way.

- Description: Students will create short videos in the style of digital influencers explaining the processes of separating mixtures. They should use social media (such as TikTok or Instagram) to record and share their explanations, making learning a fun and interactive experience.

- Instructions:

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

• Each group chooses a separation process (decantation, filtration, or distillation) to specialize in.

• Students should research visual examples and everyday contexts where the chosen process is applied.

• With the teacher's guidance, groups will record short videos (1 to 3 minutes) in the style of digital influencers, explaining the process and demonstrating the experiment using simple materials found at home.

• The videos should be creative, informative, and engaging, aiming to capture the attention of the young audience.

• The videos will be shared in the classroom, and students will vote for the most informative and creative videos.

• Groups will discuss the feedback received and reflect on the effectiveness of their presentations.

Activity 3 -  Game Time: Separation of Mixtures

> Duration: 60 - 70 minutes

- Objective: Promote student engagement through gamification, solidifying knowledge about separation of mixtures in a fun and interactive way.

- Description: Students will participate in an online educational game where they need to apply their knowledge about the separation of mixtures to advance levels. The game involves challenges and questions that test their understanding of separation processes.

- Instructions:

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

• Each group will access an online educational game designed to teach processes of separating mixtures (e.g., ChemCaper, Legends of Alkhimia).

• Students must work together to solve the challenges presented in the game, which involve practical application of methods such as decantation, filtration, and distillation.

• Groups will note their strategies and results obtained in each challenge.

• At the end of the game, each group must prepare a brief digital report (using Google Docs or similar) describing the lessons learned, the separation methods used, and the difficulties faced.

• Groups will share their reports with the class and discuss the different approaches used to solve the challenges.

Feedback

Duration: (20 - 25 minutes)

The purpose of this stage is to consolidate learning through socialization and the exchange of knowledge among students. Group discussion and 360° feedback encourage critical reflection, evaluation of one's practices, and the development of interpersonal and collaborative skills, essential both for the academic context and for professional life.

Group Discussion

 Group Discussion: Start the discussion by asking each group to share their digital presentations and reports. Use the following script to guide the discussion:

1. Request a brief presentation from each group about the activity performed.
2. Ask them to share which separation methods were used and their respective effectiveness.
3. Encourage students to discuss the difficulties faced and how they overcame them.
4. Promote a comparison between the results obtained by different groups, highlighting similarities and differences.

Reflections

1.  What were the main difficulties encountered when separating the mixtures? How did you overcome them? 2.  How did the practical activities help you better understand the theoretical concepts of separation of mixtures? 3.  How do you think the processes of separating mixtures could be applied in different industries or everyday life?

360° Feedback

 360° Feedback: Instruct students to conduct a 360° feedback session, where each student receives feedback from their peers about their performance in the group. Guide them to ensure that feedback is constructive, respectful, and focused on three points:

1. Positive aspects of the work and the contribution of the peer.
2. Areas where the peer can improve.
3. Practical suggestions for future enhancement.

Conclusion

Duration: (5 - 10 minutes)

 Purpose: This concluding stage aims to reinforce the concepts learned in a light and fun way, connecting them with the students' daily lives and the modern world. Additionally, it serves to contextualize the practical importance of what has been studied, preparing students to think critically about how this knowledge applies outside the classroom and encouraging an integrative view of learning.

Summary

 Fun Summary: Imagine you are a great chef, but instead of culinary ingredients, you use chemical elements! Today, we explored how to separate the mixtures that make up our 'chemical menu' through processes such as decantation, filtration, and distillation. Just like a chef needs to separate ingredients to create perfect dishes, we need to separate substances to obtain pure and usable products! 離

World Connection

 Connection to the Current World: In the modern world, understanding how to separate mixtures is essential for countless industries, from water purification to the production of medicines and food. In a global context where sustainability and efficiency are fundamental, these chemical processes play a crucial role in preserving natural resources and improving quality of life. The digitization of this knowledge, through simulations and digital applications used in the lesson, reflects the growing trend of integrating technology into teaching and industrial practices.

Practical Application

 Applications in Everyday Life: Knowing how to separate mixtures is a practical skill that goes far beyond the classroom. From brewing filtered coffee in the morning to separating oil from water while cooking, these chemical principles are applicable in various everyday situations. Furthermore, in a broader context, these processes are vital for drinking water treatment, oil extraction, and distilled beverage production, demonstrating the ongoing relevance of this knowledge in our daily lives.
