Lesson Plan | Teachy Methodology | Substances and Mixtures

Objectives

Duration: 10 - 15 minutes

This stage of the lesson plan is fundamental to establish a clear understanding of the skills that students should acquire by the end of the class. By defining the objectives, the teacher can guide the activities in a way that ensures that students can differentiate between substances and mixtures, identify pure and compound substances, and classify types of mixtures. This provides a solid foundation for subsequent practical activities and ensures that all students understand what is expected of them.

Main Objectives

1. Differentiate substances from mixtures.

2. Recognize types of substances: pure and compound.

3. Classify different types of mixtures.

Side Objectives

1. Foster analytical skills by evaluating everyday examples.
2. Stimulate curiosity and scientific investigation.

Introduction

Duration: 10 - 15 minutes

The purpose of this stage is to activate students' prior knowledge and engage them immediately in the topic being addressed. By asking them to find interesting facts about substances and mixtures, they feel more connected to the content, subsequently enriching the debate. The key questions serve to guide the discussion and allow students to share their impressions and acquired knowledge, preparing them for the more practical activities to follow.

Warming Up

To start the class on Substances and Mixtures, explain to students that today they will explore in more depth how to understand and differentiate these concepts that are fundamental in chemistry and also in our daily lives. Ask students to use their cell phones to search for an interesting fact about substances or mixtures. For example, they can look up how metal alloys are formed or what the purest known substance is. This way, everyone will be engaged from the beginning and bringing contributions to the class.

Initial Reflections

1. What differentiates a pure substance from a compound substance?

2. What examples of homogeneous and heterogeneous mixtures do you know from everyday life?

3. Why is it important to differentiate between substances and mixtures in practical situations?

4. How can social media and the internet help or hinder the dissemination of correct information about substances and mixtures?

Development

Duration: 70 - 85 minutes

The purpose of this stage of the lesson plan is to provide students with a practical and engaging experience, where they can apply the acquired knowledge creatively and in context using digital technologies. This not only reinforces theoretical learning but also develops important skills such as research, communication, teamwork, and problem-solving.

- Instructions:

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

• Direct the students to a virtual Escape Room website, such as Breakout EDU or Genially.

• Instruct each group to create an account and access the designated escape room for the class.

• The riddles will include puzzles about the differentiation between pure and compound substances, homogeneous and heterogeneous mixtures, and the classification of everyday examples.

• Groups must collaborate and use online resources to solve each riddle, unlocking the next steps.

• During the activity, circulate around the room (or monitor virtually) to provide assistance and check progress.

• After solving all the riddles, groups should complete a brief digital report on what they learned.

Activity 3 - Chemistry on Social Media 📱: Analyzing and Creating Viral Content

> Duration: 60 - 70 minutes

- Objective: Develop critical and creative skills by analyzing and producing media content, aligning scientific information with effective communication elements.

- Description: Students will use social media to find and analyze popular content (memes, videos, posts) that address substances and mixtures. They will then create their own content with correct and scientifically based information, aiming to make it viral.

- Instructions:

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

• Ask each group to choose a social media platform (Instagram, TikTok, Twitter, etc.) and search for content about substances and mixtures.

• Students should analyze the found content, checking the accuracy of the information and how it is presented.

• Each group must select one piece of content and create a corrective or new version using available online image and video editing tools (Canva, InShot, etc.).

• Students should consider elements that make content viral, such as humor, clarity, and visual quality.

• Ask the groups to share their created content with the class through a common platform (Google Meet, Padlet, etc.).

• Reserve time for a final discussion where students can vote on the most creative and informative content.

Feedback

Duration: (15 - 20 minutes)

The purpose of this stage of the lesson plan is to promote a deep reflection on the learning acquired, encouraging the exchange of experiences and constructive feedback. This helps consolidate knowledge, improve teamwork dynamics, and develop self-assessment and constructive criticism reception skills.

Group Discussion

[Group Discussion] Promote a group discussion with all students, where groups share what they learned from conducting the activity and their conclusions. Suggest a brief outline to introduce this discussion:

1. Introduction: Ask each group to briefly present the video/vlog, the content created for social media, or a summary of the Escape Room experience.
2. Key Points: Request that each group highlight the main aspects they learned about substances and mixtures.
3. Challenges: Ask what the greatest challenges encountered during the activity were and how they were overcome.
4. Practical Application: Encourage students to discuss how the concepts learned can be applied in everyday life and in other subjects.
5. Conclusion: Reinforce the importance of collaboration and the use of digital technologies in learning.

Reflections

1. What differences did you find between pure and compound substances when conducting the activities? 2. How did the experience of creating digital content help reinforce your understanding of homogeneous and heterogeneous mixtures? 3. In what ways can the skills developed during these activities (such as research, communication, and editing) be useful in other areas of knowledge and in daily life?

360° Feedback

[360° Feedback] Instruct students to carry out a 360° feedback stage, where each student should receive feedback from other students in the group they worked with on the activity. Guide the students to ensure that the feedback is constructive and respectful. Use the following structure for the feedback:

1. Positive Aspects: Each student should highlight at least one positive point about their peer's participation.
2. Opportunities for Improvement: Indicate areas where the peer can improve, always in a respectful and objective manner.
3. Personal Reflection: Each student should reflect on the feedback received and think about how they can apply it to improve in future activities.

Summary

🔬 Lesson Summary - Substances and Mixtures 🎉

Let's give a boost to the summary of the concepts we explored today! 🚀 Pure substances are those that have a single chemical composition, such as distilled water (H2O) or iron (Fe). On the other hand, compound substances are made up of more than one type of chemical element, such as water (H2O) and salt (NaCl). Mixtures can be homogeneous (solutions) or heterogeneous (those that have different visible phases). An example of a homogeneous mixture is the air we breathe, while an example of a heterogeneous mixture is a fruit salad. 🍉🍍🍎

World Connection

🌍 In Today's World 🌍

Today's lesson connects directly with the modern dynamic on various fronts. We live in a world where chemistry is everywhere, from the products we use at home to technological and scientific advancements. Understanding substances and mixtures helps us better understand the products we consume, environmental sustainability, and even engage in debates about emergent topics on social media. Furthermore, digital skills such as creating videos and viral content are essential in today's world.

Practical Application

🔧 Applications in Daily Life 🔧

Knowing how to differentiate substances from mixtures and recognizing their types is crucial in everyday life. Think about choosing products in the store, understanding food labels, or even in recycling practices and sustainability. Our students are better prepared to make informed and critical decisions, contributing to conscious consumption and a more sustainable life.
