Introduction

Duration: 10 - 15 minutes

The purpose of this stage is to provide a clear and structured overview of the main concepts that will be addressed in the class, helping students to contextualize and apply their prior knowledge in a practical and meaningful way. This will allow for better engagement and understanding of the topics discussed in the following activities.

Warming Up

To start the class, explain to the students that the study of substances and mixtures is essential for understanding both natural phenomena and industrial processes. Ask the students to use their cell phones to find an interesting fact about simple and compound substances or about mixtures in everyday life. Invite them to share these facts with the class, encouraging curiosity and the exchange of information.

Initial Reflections

1. What is a simple substance? And a compound substance?

2. What is the difference between a homogeneous mixture and a heterogeneous mixture?

3. Can you give an example of a simple substance that we use in our daily lives?

4. How would you differentiate pure water from a saltwater solution?

5. Why is it important to understand the difference between substances and mixtures?

Development

Duration: 65 - 75 minutes

The purpose of this stage is to allow students to apply their knowledge of substances and mixtures in a practical and interactive way, using digital technologies to create, investigate, and share information in an engaging manner. This increases engagement and facilitates understanding of the concepts studied, promoting active and contextualized learning.

Activity Suggestions

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

Activity 1 - Mixing Digital Influence

> Duration: 60 - 70 minutes

- Objective: To creatively apply knowledge about substances and mixtures and communicate these concepts through a digital medium popular among young people.

- Description: Students will take on the role of digital influencers and create an explanatory video for their social networks about the different types of substances and mixtures. Using video editing apps, they will create engaging and informative content that can be shared with a young audience.

- Instructions:

• Divide students into groups of up to 5 people.

• Each group should choose a social media platform of their choice (e.g., TikTok, YouTube, Instagram).

• They must research a specific type of substance or mixture and create a script for a short video (2-3 minutes).

• Using video editing apps like InShot or CapCut, each group should record and edit their video, including graphics, visual effects, and detailed explanations.

• After producing the video, each group should present their creation to the class, explaining the content clearly and engagingly.

• The videos may be shared on the students’ social networks, encouraging the dissemination of knowledge.

Activity 2 - Develop Your Chemistry Game

> Duration: 60 - 70 minutes

- Objective: To review and consolidate knowledge about substances and mixtures in a playful and interactive way, promoting collaboration and the use of digital technologies.

- Description: Students will create a digital game, using platforms like Kahoot or Quizizz, to test their peers' knowledge about substances and mixtures. This game can include multiple-choice questions, true or false questions, and interactive content.

- Instructions:

• Divide students into groups of up to 5 people.

• Each group should access the chosen website or app (Kahoot or Quizizz).

• Students must formulate questions related to the studied topic (simple and compound substances, homogeneous and heterogeneous mixtures).

• The groups must create a quiz game with at least 10 questions, including images and explanations where necessary.

• Each group plays the quiz created by another group, providing an interactive and fun review of the content.

• In the end, everyone discusses the most difficult questions and reviews the relevant concepts.

Activity 3 - Everyday Investigators

> Duration: 60 - 70 minutes

- Objective: To apply knowledge about substances and mixtures in the context of everyday life, developing skills in observation, analysis, and communication through digital technologies.

- Description: Students will conduct a vlog-style investigation about the different types of substances and mixtures they encounter in everyday life. Using their cell phones, they will record videos identifying and explaining these substances and mixtures in their everyday surroundings.

- Instructions:

• Divide students into groups of up to 5 people.

• Each group should choose an environment to investigate (e.g., kitchen, bathroom, garden, etc.).

• Using their cell phones, students should record short videos explaining which simple substances, compound substances, and mixtures they find in that environment and how to identify them.

• The groups should edit their videos to create an interesting and informative vlog, using video editing apps.

• After producing the video, each group shares their vlog with the class and explains their findings.

• The videos can be shared on a common platform, such as Google Classroom, for all students to watch and comment.

Feedback

Duration: 20 - 30 minutes

The purpose of this stage is to provide a moment of reflection and sharing, where students can consolidate their knowledge through debate and mutual feedback. This is an opportunity to deepen understanding of the concepts addressed and develop communication and collaboration skills, essential for active learning.

Group Discussion

Promote a group discussion by asking each group to share what they learned while carrying out the practical activities. Use the following outline to introduce the discussion:

Introduction: Explain the importance of sharing learnings for collective development. Group Presentations: Ask each group to present their created videos and games, briefly explaining the key points of their productions. Debate on Challenges and Discoveries: Ask students what the main challenges were during the activity and what discoveries surprised them. Conclusion: End the discussion by reinforcing the concepts learned and the importance of collaboration and the use of digital tools in learning.

Reflections

1. What were the main differences you noticed between simple and compound substances during the activities? 2. How did the activities help you better understand the concepts of homogeneous and heterogeneous mixtures? 3. In what way do you think knowledge about substances and mixtures can be applied in everyday life?

360° Feedback

Instruct students to carry out a 360° feedback stage, where each student will receive feedback from their group mates about their participation and contribution. Guide the class to ensure that the feedback is constructive and respectful, using phrases such as 'I liked how you...' or 'You could improve in...'. Encourage students to be honest but always respectful, focusing on positive aspects and suggestions for improvement.

Conclusion

Duration: 10 - 15 minutes

 Purpose: The conclusion stage aims to summarize the main contents in a fun and contextualized way, reinforcing learning and showing its relevance in the real world. It also serves to connect the studied concepts with practical applications, encouraging students to see the science around them more clearly and interestingly.

Summary

 Summary: Imagine today's class was a super trip through the world of substances and mixtures!  We saw that simple substances are like 'famous atoms' that don't mix with anyone, while compound substances are true star teams, made up of different elements. Mixtures can be homogeneous, like a well-mixed juice , or heterogeneous, like a beautiful fruit salad . It was like putting together a perfect playlist where each song (or substance) has its special place!

World Connection

 In the World: In this digital world, knowing how to differentiate substances and mixtures is like understanding the algorithms of social networks. Just as algorithms define what you see in your feed, understanding these differences helps comprehend important processes in technology, industry, and even our health. And who knows, maybe you can make a viral video about this and become a digital science influencer? 

Practical Application

 Applications: Knowing about substances and mixtures is crucial for everyday life! Whether cooking, choosing cleaning products, or even understanding natural phenomena. This makes life more practical and interesting, allowing for more informed and conscious decisions. After all, knowledge is the best tool to navigate the modern world safely and creatively! 易✨
