Activity Suggestions

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

Activity 1 - Chemical Influencers 🚀

> Duration: 60 - 70 minutes

- Objective: Utilize students' creativity and technological skills to teach aldehyde nomenclature in a modern and engaging way.

- Description: In this activity, students must create a short video in the style of social media, such as TikTok or Instagram Reels, explaining the nomenclature of a specific aldehyde. They should use editing resources like filters and transitions to make the explanation engaging and easy to understand.

- Instructions:

• Divide students into groups of up to 5 people.

• Each group must choose a specific aldehyde to work with.

• Using their phones, students must create a short (60 seconds) video explaining the IUPAC nomenclature of the chosen aldehyde.

• Videos should be creative and educational, using visual and editing resources to attract attention.

• Encourage groups to incorporate practical examples or curiosities about the chosen aldehyde.

• After the videos are created, each group must share the video with the class.

• Videos can be presented in the classroom or sent to a shared platform (e.g., Google Classroom, WhatsApp).

Activity 2 - Chemical Detective Game 🕵️‍♀️

> Duration: 60 - 70 minutes

- Objective: Develop investigative and analytical skills by identifying and naming aldehydes using supportive digital technologies.

- Description: Students will participate in a chemistry detective game where they will receive digital clues about different compounds. They must use chemistry apps and online resources to identify which compound is an aldehyde and name it correctly.

- Instructions:

• Divide students into groups of up to 5 people.

• Each group will receive a list of digital clues detailing characteristics of different organic compounds.

• Using chemistry apps (like ChemDoodle) and online resources, students must investigate the clues to identify which are aldehydes.

• Once identified, they must correctly name the aldehydes using IUPAC nomenclature.

• Groups must record their answers and justifications in a shared document (e.g., Google Docs).

• After the designated time, each group must present their findings and the investigation process to the class.

• The class can discuss and validate each other's answers.

Activity 3 - Chemical Storytelling Challenge 📚

> Duration: 60 - 70 minutes

- Objective: Stimulate creativity and the ability to integrate chemical concepts into an engaging narrative, using multimedia resources to enrich learning.

- Description: In this activity, students must create a story or narrative incorporating different aldehydes and their nomenclatures. The story should be published in a blog or digital text format, using images and videos to enrich the content.

- Instructions:

• Divide students into groups of up to 5 people.

• Each group must develop a story or narrative that includes at least three different aldehydes and their IUPAC nomenclatures.

• Students can be creative with the plot but must ensure that the nomenclature and structures of the aldehydes are correct and well explained.

• Using digital resources, such as blogs (e.g., WordPress) or collaborative text editors (e.g., Google Docs), groups must create and publish their stories.

• Encourage students to include images, videos, or links that complement the narrative and explain the chemical concepts visually.

• Each group must share the link to their story with the class so that everyone can read and comment.

• The teacher may select some stories for reading and discussion in class.

Feedback

Duration: 15 - 20 minutes

This stage aims to promote critical reflection on the learning process and the activities carried out. Through group discussion, students have the opportunity to consolidate their knowledge by hearing different perspectives and sharing their findings. The 360° feedback encourages the development of communication and self-reflection skills, which are fundamental for personal and academic growth.

Group Discussion

Group Discussion 🗣️

Facilitate a group discussion where each group shares their experiences and conclusions from the activities carried out. Use the outline below to introduce the discussion:

1. Introduction - Start by asking students how the process of creating the videos, games, and stories went. Ask if they encountered any difficulties and how they overcame them.

2. Sharing - Invite each group to briefly present the final product of the activities and explain what the main learnings were.

3. Practical Application - Ask students how they think knowledge about aldehydes can be useful in their daily lives or future careers.

4. Comparison - Encourage groups to compare their approaches and methods, highlighting what worked well and what could be improved.

Reflections

1. What were the biggest challenges you faced when creating the videos, games, or stories about aldehyde nomenclature? 2. How did the practical activities help you better understand IUPAC nomenclature of aldehydes? 3. In what ways did group collaboration contribute to your learning?

360° Feedback

360° Feedback 🔄

Instruct students to conduct a 360° feedback session. Each student should receive feedback from other group members regarding their participation and contributions. Guide the class to follow these guidelines to ensure that feedback is constructive and respectful:

1. Be Specific - Give concrete examples of what the colleague did well or could improve.

2. Be Respectful - Use respectful language and focus on behavior, not the person.

3. Be Constructive - Offer practical suggestions on how the colleague can improve.
