Activity Suggestions

Activity Recommendations

Activity 1 - 🎮 Digital Battle: Collision Simulation

> Duration: 60 - 70 minutes

- Goal: Apply concepts of momentum and the impulse theorem in a practical, visual manner, enhancing understanding through digital experimentation.

- Deskripsi Activity: Students will partake in a digital competition using an online collision simulator. Each group will create a collision scenario involving objects with different masses and velocities. They will leverage the simulator to predict the outcomes and verify the impulse theorem and conservation of momentum.

- Instructions:

• Split the class into groups of up to 5 students.

• Each group must access an online collision simulator (e.g., 'PhET Interactive Simulations').

• Ask each group to design a collision scenario by setting the initial masses and velocities of the objects.

• Groups should document the initial conditions and predict the results using momentum and the impulse theorem.

• Run the simulation and compare the actual results with their predictions.

• Each group must take a screenshot of their results and prepare a short presentation of their conclusions.

• At the end, all groups share their findings with the class.

Activity 2 - 📱 Physics Influencers: Social Media Case Studies

> Duration: 60 - 70 minutes

- Goal: Develop the ability to communicate scientific concepts clearly and accessibly using modern digital tools.

- Deskripsi Activity: Students will step into the role of 'digital influencers' of physics, creating social media posts that clarify real collision and impulse phenomena. They should utilize practical examples like sports videos or traffic incidents and explain the concepts with accessible, visual language.

- Instructions:

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

• Each group must select an online video showcasing a collision (e.g., sports events, car crashes, natural phenomena).

• Groups should analyze the video, identifying the concepts of momentum and impulse in play.

• Create a post for a social media platform (e.g., Instagram, TikTok) that explains the event using graphics, animations, or explanatory text.

• Students must use video and graphic editing apps to make their posts visually appealing.

• Each group shares their post with the class and discusses the scientific accuracy and clarity of their explanations.

Activity 3 - 🕵️ Physical CSI: Collision Investigation

> Duration: 60 - 70 minutes

- Goal: Apply theoretical concepts in practical scenarios while developing investigation and data analysis skills through digital tools.

- Deskripsi Activity: Students will take on the role of investigators in a case study involving a traffic accident. Using authentic data and digital tools, they must reconstruct the accident and determine if momentum was conserved and how the impulse theorem relates.

- Instructions:

• Split the class into groups of up to 5 students.

• Provide each group with a fictitious study case of a traffic accident, including details like vehicle masses, speeds, and angles of collision.

• Students should use data analysis and simulation software (e.g., Tracker Video Analysis) to recreate the circumstances of the accident.

• Calculate the momentum before and after the collision, applying the impulse theorem to analyze the situation.

• Each group must prepare a detailed digital report of their findings and create a slide presentation for the class.

• Groups present their conclusions and discuss the real-world applications of the concepts studied.

Feedback

Duration: (20 - 25 minutes)

This stage of the lesson plan intends to provide a moment for collective and individual reflection on what has been learned, ensuring that the concepts are understood and that the collaborative experience has been meaningful. Group discussion and 360° feedback foster a continuous and respectful learning environment where students can acknowledge their contributions and pinpoint avenues for improvement, enriching the teaching-learning process.

Group Discussion

To facilitate group discussion, start by asking each group to briefly share their experiences and conclusions. Pay attention to highlight common interests and differences among the groups' methods. Use the following outline to introduce the discussion:

1. Ask each group to present their key findings, emphasizing the most surprising or challenging aspects.
2. Inquire how the activity helped them better understand the concepts of momentum and the impulse theorem.
3. Encourage students to reflect on how these concepts apply to everyday situations they have observed or encountered.

Reflections

1. In your own words, how would you explain the relationship between momentum and the impulse theorem? 2. What were the biggest challenges you faced when using the simulator to predict collision outcomes? 3. How do you think grasping these concepts can benefit you in other subjects or daily situations?

Feedback 360º

Guide students to conduct a 360° feedback exercise right after the group discussion. Every student should receive feedback from their peers regarding their contributions during the activity. Instruct them to follow these guidelines for constructive and respectful feedback:

1. Highlight a positive aspect of a colleague's involvement.
2. Suggest a specific area for improvement in a gentle manner.
3. Conclude with an encouraging remark for the colleague to continue developing their skills.
