Activity Suggestions

Activity Recommendations

Activity 1 - 👩‍🔬 Science Influencer Experiment: The Work of Gas in Practice

> Duration: 60 - 70 minutes

- Goal: Apply theoretical concepts of thermodynamics in a practical experiment while honing communication skills and video editing abilities.

- Deskripsi Activity: In this activity, students will create a video in the style of a 'digital influencer' that explains a practical experiment about the work of a gas. They can use their phones to record an experiment at home or in the lab and edit the video, incorporating theoretical explanations and PV graphs.

- Instructions:

• Divide learners into groups of up to 5.

• Each group will choose a simple experiment that shows the concept of work done by a gas (like inflating a balloon, or using a syringe without a needle to compress air).

• Students will record the experiment with their phones, highlighting the changes in volume and pressure of the gas.

• After recording, learners will edit the video on a computer or use editing software on their phones.

• Incorporate theoretical explanations, calculations, and PV graphs to demonstrate how pressure and volume change during the experiment.

• Each group will then publish the video on a platform suggested by the teacher (like YouTube or Google Drive) and share the link with the class.

Activity 2 - 📱 Gamification: The Thermodynamics Game

> Duration: 60 - 70 minutes

- Goal: Enhance problem-solving skills and apply theoretical thermodynamics knowledge in a fun, interactive environment.

- Deskripsi Activity: Students will take part in an interactive online game where they need to solve thermodynamic problems to progress to the next level. Each question will focus on different gas transformations and calculations of work done by a gas.

- Instructions:

• Divide learners into groups of up to 5 and have each group access an online thermodynamics game, such as 'PhET Interactive Simulations'.

• Explain that the aim of the game is to solve thermodynamic problems related to the work of a gas to earn points and move on to tougher challenges.

• Students should discuss their solutions in groups and collaborate on answering each question.

• Each group should take screenshots of their answers and correct solutions for each level.

• At the end of the activity, each group should present their findings, explaining the logic behind their answers and displaying the screenshots as evidence of their progress in the game.

Activity 3 - 🌍 Storytelling on Instagram: The Journey of a Gas

> Duration: 60 - 70 minutes

- Goal: Use storytelling and social media skills to teach thermodynamic concepts, making learning more relatable and engaging.

- Deskripsi Activity: Students will create an Instagram story that narrates the 'journey' of a gas through different transformations, using graphs, images, and videos. Their story will explain how the work done by the gas changes in each transformation.

- Instructions:

• Divide learners into groups of up to 5.

• Each group should create a dedicated Instagram account for this activity or use a temporary account provided by the teacher.

• Students will compile an Instagram 'story' composed of several segments showcasing the journey of a gas through transformations (isothermal, isobaric, etc.).

• Each segment should feature PV graphs, text explanations, images, or short videos illustrating the gas transformation and the calculations of work done.

• The groups must follow a logical sequence to ensure public understanding of the transformations and the work done by the gas.

• At the end, each group should share the link to their story with the class and give a brief explanation of their choices and content.

Feedback

Duration: 20 - 25 minutes

The goal of this stage is to provide an opportunity for students to reflect on their learnings and how they applied theoretical concepts in practical ways. The group discussion and 360° feedback foster a collaborative environment where learners can benefit from one another, develop communication skills, and receive valuable suggestions for improving their future efforts.

Group Discussion

Facilitate a group discussion with all students, where groups present what they learned during their experiments and discuss their conclusions. Follow this suggested script to guide the discussion:

Group Discussion Script:

1. Introduction: Welcome students and highlight the importance of sharing their learnings.
2. Group Presentations: Ask each group to showcase their video or Instagram story, focusing on key takeaways and lessons learned.
3. Open Discussion: After each presentation, allow for questions and comments from peers. Encourage constructive conversation.
4. Final Synthesis: Wrap up by summarising the main points discussed and reinforcing how thermodynamic concepts apply in everyday life.

Reflections

1. How did the practical activities enhance your understanding of the work done by a gas? 2. What challenges did you face during the activities and how did you overcome them? 3. How did using digital tools and social media clarify the application of thermodynamics concepts?

Feedback 360º

Conduct a 360° feedback session, where each student receives constructive feedback from their peers in their group. Guide the class to ensure the feedback is respectful and focused, highlighting positives and suggestions for improvement. Encourage the use of the 'SBI' method (Situation, Behaviour, Impact), describing a specific situation, the observed behaviour, and the effect it had.

Conclusion

Duration: 10 - 15 minutes
