Duration: 75 - 90 minutes

The purpose of this phase is to enrich and deepen students' knowledge on organic addition reactions through practical and contextualized activities. Using digital tools, students engage actively and creatively in learning, applying theoretical concepts in practical and modern situations.

Activity Suggestions

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

Activity 1 - Chemical Digital Influencers

> Duration: 60 - 70 minutes

- Objective: Make students understand and explain addition reactions contextually and creatively, using digital tools to simulate scientific communication on social networks.

- Description: Students will become digital influencers and will create a series of posts on a fictitious social network explaining addition reactions. Using cell phones and editing apps, students will develop multimedia content (short videos, images, infographics) that explain concepts such as the main types of addition reactions, the role of catalysts, and practical applications.

- Instructions:

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

• Each group must create a profile on a fictitious social network (create a document or presentation that simulates the interface of a social network).

• Using their cell phones, the groups will create at least 3 multimedia posts (they can include videos, images, and explanatory texts) on the following topics: addition reactions, role of catalysts in addition reactions, and industrial/biological applications.

• After preparing the content, groups must present their profiles to the class, explaining the creation process and the content of the posts.

• Students can use video and image editing apps to enhance the quality of the posts. Encourage creativity!

Activity 2 - Chemical Detectives

> Duration: 60 - 70 minutes

- Objective: Develop students' ability to apply theoretical knowledge in practical and contextualized situations, promoting research and the resolution of complex problems.

- Description: Students will act as scientific detectives solving a chemical mystery. They will receive a fictitious case involving the synthesis of an organic compound through addition reactions. Using online resources, groups will research and propose the ideal synthetic pathway, considering catalysts and resulting products.

- Instructions:

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

• Distribute a 'case' to each group (a document describing a chemical problem that requires a solution through addition reactions).

• Students must use computers and cell phones to research information about possible synthetic pathways, catalysts, and products.

• Each group must prepare a presentation explaining the solution to the case, highlighting the steps of the reaction, the catalysts used, and the products obtained.

• Ask each group to present their solution to the class. Encourage questions and discussions to deepen understanding.

Activity 3 - Chemical Quiz Show

> Duration: 60 - 70 minutes

- Objective: Review and reinforce students' knowledge about addition reactions in a playful and interactive way, encouraging healthy competition and group collaboration.

- Description: Students will participate in a gamified quiz show about addition reactions. Using a quiz app, groups will compete by answering multiple-choice questions, true or false, and open questions. The goal is to review and reinforce the content in a fun and interactive way.

- Instructions:

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

• Use a quiz app (such as Kahoot, Quizizz) to create a quiz with questions about addition reactions, types of reactions, catalysts, and practical applications.

• Each group will use a cell phone to participate in the quiz.

• The quiz should be divided into rounds, with questions of varying difficulty levels. After each round, the group with the highest score can win a symbolic reward (for example, stickers or praise).

• At the end of the quiz, review the answers with the class, explaining in detail the most challenging questions.

Feedback

Duration: 20 - 25 minutes

 Purpose: The purpose of this phase is to consolidate learning, promoting reflection and sharing of experiences among students. Through group discussion and 360° feedback, students have the opportunity to reinforce concepts, recognize their own progress, and value the contributions of their peers, culminating in a deeper and more integrated understanding of addition reactions.

Group Discussion

 Group Discussion: Promote a group discussion with all students so that groups can share their experiences and conclusions. Use the following script to introduce the discussion:

1. Introduction: Reinforce the importance of addition reactions and how they are applied in real contexts, both industrial and biological.
2. Sharing: Ask each group to briefly share the content they created during the activities. Encourage them to explain their choices, difficulties, and learnings.
3. Questions and Answers: Open the floor for classmates to ask questions about the posts and the cases investigated by other groups. Promote a constructive dialogue where everyone can contribute insights and observations.
4. Summary: Summarize the main points discussed, highlighting the most important aspects of addition reactions and their practical applications.

Reflections

1. What were the main challenges you encountered while creating the digital posts about addition reactions? 2. How did the research on catalysts and products help you better understand the process of addition reactions? 3. What practical application of addition reactions caught your attention the most and why?

360° Feedback

️ 360° Feedback: Instruct students to interact with their group peers, providing constructive feedback on their contributions during the activities. Guide them to focus on the following points:

1. Strengths: Identify and praise the positive contributions that each peer brought to the group.
2. Areas for Improvement: Suggest ways to make collaboration even more effective, always using respectful and encouraging language.
3. Learning Experience: Relate how the peer's collaboration helped in personal learning about addition reactions.
