- Instructions:

• Divide students into groups of up to 5.

• Each group should access the online engine simulator (provide a specific link).

• Students must construct a virtual engine according to the steps indicated by the simulator.

• Identify and explain each phase of the thermodynamic cycle within the virtual engine.

• Take screenshots or record videos of the key stages and prepare a brief presentation using slides or an explanatory video that details how the thermodynamic cycle functions within the engine.

Activity 2 - 🎮 Gamified Thermodynamics

> Duration: (60 - 70 minutes)

- Goal: Engage students in resolving thermodynamics challenges in a playful and collaborative way, utilizing critical thinking as well as teamwork skills.

- Deskripsi Activity: Students will engage in a digital escape room game where they need to solve various puzzles and problems related to thermodynamic cycles to 'escape' a fictional scenario. The digital environment can be created using gamification platforms and interactive tools.

- Instructions:

• Divide students into groups of up to 5.

• Create a digital escape room using online tools (e.g., Google Forms, Kahoot, or specific escape room platforms).

• Each group will access the digital escape room link and solve the provided puzzles, which will include calculations of heat exchanged, internal energy, and work done.

• Students must collaborate to solve problems and proceed to the next stage.

• The group that completes all the puzzles first wins, but all groups need to finish the activity within the allotted time.

Activity 3 - 📱 Thermodynamics Influencers

> Duration: (60 - 70 minutes)

- Goal: Cultivate the ability to communicate scientific concepts clearly and engagingly using digital tools and social media.

- Deskripsi Activity: Students will turn into 'digital influencers of physics' by creating content on social media (like short videos for TikTok or posts for Instagram) that explains what a thermodynamic cycle is and why it’s important. They should use creative analogies and everyday examples.

- Instructions:

• Divide students into groups of up to 5.

• Each group should choose a social media platform (TikTok, Instagram, YouTube) to create their content.

• Students must plan their content, deciding how they'll depict the thermodynamic cycle in an understandable and captivating manner.

• Record short videos, create infographics, or develop posts that clarify the concept creatively.

• Share the content on their chosen social media platform and present it to the class. If the school doesn’t permit actual posting, students can simulate the presentation.

Feedback

Duration: (25 - 30 minutes)

🎯 Purpose: The aim of this stage is to encourage reflection on the learning acquired, reinforcing the understanding of tackled concepts and enhancing communication and self-assessment skills. The group discussion fosters an environment for students to share experiences and learn from each other, while the 360° feedback helps with social and emotional growth, preparing them to collaborate effectively in a respectful manner.

Group Discussion

Summary

🌥️ Climate and Thermodynamics! 🌡️ - Picture a sunny day when you step outside and feel the warmth of the sun on your skin. Now, recall the activities we did on thermodynamic cycles, like building a virtual engine and participating in a digital escape room. Just as the sun heats the Earth, in an engine, fuel is combusted (much like the sun), expanding gases and performing work (like moving a vehicle). The concepts of heat exchange, internal energy, and work done become clearer and more engaging when we visualize them through interactive and challenging practice, right? 🚗💨
