Activity Suggestions

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

Activity 1 - Cyclic Hydrocarbon Digital Detectives 💻🔍

> Duration: 60 - 70 minutes

- Objective: Apply knowledge about cyclic hydrocarbons to solve practical problems, developing investigative and critical analysis skills.

- Description: Students must create a fictional profile on a social network (it can be an educational platform like Google Classroom or a simulated social network) of a digital detective specialized in cyclic hydrocarbons. The objective is to solve a mysterious case where reactive chemicals are causing problems in a factory. Students must use their detective skills to investigate and identify the compounds responsible for the problem based on the properties of cyclic hydrocarbons.

- Instructions:

• Divide students into groups of up to 5 people.

• Each group must create a digital detective profile on a simulated social network platform.

• Present the scenario of the mysterious case: a factory is facing safety problems due to the reactivity of certain chemical compounds present in its products.

• Groups must investigate the characteristics and reactivities of cyclic hydrocarbons to identify the responsible compounds.

• Students must document their findings and hypotheses in posts and interactions on the detective profile.

• At the end, each group must present their conclusion and collected evidence in a final report post.

Activity 2 - Scientific Influencers on TikTok 📱🎥

> Duration: 60 - 70 minutes

- Objective: Develop scientific communication skills and creativity by explaining chemistry concepts in an accessible and fun way.

- Description: Students must create short videos in TikTok format, explaining in a fun and informative way the properties and characteristics of cyclic hydrocarbons. The videos should include practical examples and be aimed at a young audience who is unaware of the subject. Creativity and the ability to explain complex concepts in a simple way will be evaluated.

- Instructions:

• Divide students into groups of up to 5 people.

• Each group must plan and script a short video (1 to 3 minutes) about cyclic hydrocarbons.

• The videos must explain the characteristics, properties, and applications of cyclic hydrocarbons in a creative and engaging way.

• Students can use visual effects, music, and other tools available in video creation apps.

• The videos must be recorded and edited using cell phones and available apps.

• After recording, each group must present their video to the class as if posting on a social network.

Activity 3 - Augmented Reality Game: Hydrocarbon Challenge 🎮🕹️

> Duration: 60 - 70 minutes

- Objective: Use augmented reality technology to reinforce the understanding of the properties of cyclic hydrocarbons in an interactive and playful way.

- Description: Students will participate in an augmented reality game in which they must find and identify different cyclic hydrocarbons scattered around the room. Using an AR app on their cell phones, students will scan QR codes that will lead them to puzzles and challenges related to the properties of the compounds. Each stage of the game will include questions and tasks that students need to complete to advance in the game.

- Instructions:

• Divide students into groups of up to 5 people.

• Set up the room with different stations of QR codes representing cyclic hydrocarbons.

• Instruct students to download an appropriate augmented reality app for the activity.

• Students must use their phones to scan the QR codes and access challenges related to the properties and characteristics of the compounds.

• Each station will include a puzzle or question that students must solve to advance in the game.

• At the end of the game, students must present a summary of their discoveries and challenges faced during the activity.

Feedback

Duration: 20 - 25 minutes

The purpose of this stage is to consolidate learning and stimulate critical reflection on the activities performed. Group discussion allows students to share and validate their experiences, while 360° feedback promotes a culture of collaboration and continuous growth. This stage reinforces students' proactive role in the learning process, encouraging the exchange of ideas and self-assessment.

Group Discussion

Suggest that each group share their findings and conclusions with the class. Start the discussion by asking what challenges they faced and how they resolved each one. Encourage them to talk about the strategies used to identify cyclic hydrocarbons and the importance of these molecules in different contexts. Ask each group to explain their investigative processes, their choices of approach, and what they found most interesting or surprising during the activities.

Reflections

1. What were the main challenges encountered during the activities and how did you overcome them? 2. How did the use of digital technologies (augmented reality, social networks, videos) help you better understand the properties of cyclic hydrocarbons? 3. How would you relate the characteristics and reactivities of cyclic hydrocarbons to their practical applications in daily life?

360° Feedback

Instruct students to conduct a round of 360° feedback. Each student should provide constructive feedback for their group members, highlighting strengths and suggesting areas for improvement. Guide the class on the importance of maintaining a respectful and encouraging tone during feedback. Suggest that they use phrases like: 'I really liked how you...', 'You could improve in...', 'It was interesting when you...'.
