Activity Suggestions

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

Activity 1 - 🔍 Chemistry Detectives: Investigating Elimination Reactions

> Duration: (60 - 70 minutes)

- Objective: Develop research and problem-solving skills by exploring elimination reactions in an investigative scenario.

- Description: Students will be divided into groups and act as 'chemical detectives' to solve a fictional case related to an elimination reaction that occurred in a chemistry lab. They will use tablets and phones to research, collect clues, and virtual evidence to help them solve the case. Each group will present their findings and the solution to the case at the end of the activity.

- Instructions:

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

• Give each group a set of initial clues about a specific elimination reaction (e.g., elimination of alkyl halides).

• Ask the groups to use their mobile devices to research additional information about the reaction, including catalysts, reaction conditions, and products formed.

• Groups should prepare a digital report with their findings, using tools like Google Docs or Microsoft Word.

• Each group should present their findings and conclusions to the class, justifying the investigated elimination reaction and the resulting products.

Activity 2 - 🎮 Gamification: The Elimination Reactions Challenge

> Duration: (60 - 70 minutes)

- Objective: Reinforce knowledge about elimination reactions in a playful and interactive way, promoting engagement and collaboration.

- Description: Students will compete in an interactive digital quiz using platforms like Kahoot! or Quizizz. They will answer questions about elimination reactions, including types, catalysts, and products, accumulating points as they progress. The group or student with the most points at the end of the quiz will be declared the winner.

- Instructions:

• Divide the students into groups of up to 5 people or allow them to participate individually.

• Create an interactive quiz on a digital platform, including questions about the concepts of elimination reactions.

• Explain the rules of the quiz and how students should use their mobile devices to participate.

• Start the quiz and monitor student progress in real time, providing immediate feedback on answers.

• At the end of the quiz, briefly discuss the questions and answers, highlighting the main lessons learned.

Activity 3 - 📱 Digital Influencers: Campaign about Elimination Reactions

> Duration: (60 - 70 minutes)

- Objective: Develop digital communication skills and translate scientific knowledge for diverse audiences using accessible and creative language.

- Description: Students will create a social media campaign to explain elimination reactions to the general public. They can create videos, posts, and infographics using editing and publishing apps. The goal is to translate complex chemistry concepts into accessible and visually appealing language.

- Instructions:

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

• Ask the groups to choose a social media platform (Instagram, TikTok, YouTube, etc.) and define a target audience.

• Each group must create a content plan, including videos, posts, and infographics that explain elimination reactions.

• Students will use editing apps (Canva, InShot, etc.) to produce their content.

• Each group will present their campaign to the class, explaining their design choices and how they translated the chemistry concepts.

Feedback

Duration: (15 - 20 minutes)

🚀 Purpose: This stage aims to promote deep reflection on learning, encourage collaboration and communication among students, as well as consolidate the knowledge acquired. Through group discussion and 360° feedback, students develop self-criticism and critical observation skills, essential for academic and personal growth.

Group Discussion

📢 Group Discussion: Facilitate a discussion where each group shares their experiences and discoveries obtained during the activities. Use a brief script to guide the discussion:

1. Introduction: Explain the importance of sharing learning experiences.
2. Contributions from Groups: Invite each group to present a summary of their activities, focusing on the elimination reactions studied, catalysts, reaction conditions, and resulting products.
3. General Conclusions: Ask students about the challenges and most significant learnings during the activity.
4. Connections to Real Life: Encourage students to discuss how the knowledge acquired can be applied in contexts outside the classroom, such as in the chemical and pharmaceutical industry.

Reflections

1. How can elimination reactions be applied in practical situations of daily life or in the industry? 2. What were the main challenges encountered during the activities and how did you resolve them? 3. How did the use of digital technologies facilitate or hinder the learning of elimination reaction concepts?

360° Feedback

🔄 360° Feedback: Guide students to conduct a 360° feedback stage, where each group member receives feedback from their peers. Emphasize the importance of being constructive and respectful. Structure the feedback with the following guidelines:

1. Positive Aspects: Start by mentioning what the peer did well during the activity.
