Activity Suggestions

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

Activity 1 - 🎮 Digital Collisions - Gamification Challenge

> Duration: 60 - 70 minutes

- Objective: Apply the concept of conservation of momentum in a practical and playful context, reinforcing understanding through the creation of a digital game.

- Description: In this activity, students will create a simple game using an online game development platform, such as Scratch, to simulate collisions between objects. They must program different collision scenarios and observe the conservation of momentum.

- Instructions:

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

• Ask them to access the Scratch platform (or another simple game development platform).

• Explain that they must create a game where two objects collide. They should program the behavior of the objects before and after the collision, verifying the conservation of momentum.

• Encourage them to add different levels of difficulty, varying the mass and speed of the objects.

• Each group must present their game to the class, explaining how they applied the concept of conservation of momentum.

• Groups can use tutorials and online resources to help in creating the game.

Activity 2 - 📱 Digital Influencers - Unraveling Collisions on Instagram

> Duration: 60 - 70 minutes

- Objective: Utilize social media to communicate scientific concepts, making learning more dynamic and contextualized with students' reality.

- Description: Students will create a series of stories on Instagram explaining the concept of conservation of momentum through examples from everyday life and simple experiments they can conduct at home. They should use images, videos, and text to communicate their ideas creatively and clearly.

- Instructions:

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

• Ask students to use their cell phones to access Instagram.

• Each group must create a temporary account (if they do not want to use their personal accounts) for the activity.

• Explain that they must create a series of stories explaining the conservation of momentum. The stories should include:

• Practical examples of everyday collisions (such as sports, traffic accidents, etc.).

• Videos of small home experiments demonstrating the concept.

• Simplified and visually appealing theoretical explanations.

• Practical tips on how to calculate momentum in different situations.

• Each group must present their series of stories to the class, explaining the reasoning behind each example and experiment.

Activity 3 - 🔍 CSI: Collision Investigation

> Duration: 60 - 70 minutes

- Objective: Develop investigative and analytical skills by applying the concept of conservation of momentum in a realistic scenario.

- Description: In this activity, students will act as investigators of a vehicle collision scene. Using online simulations and provided data, they must determine the speeds of the vehicles before and after the collision, applying the concept of conservation of momentum.

- Instructions:

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

• Distribute a fictional collision scenario to each group, including data such as vehicle masses and the state before and after the collision.

• Ask students to use online collision simulators (like the PhET Collision Lab) to recreate the scenario.

• Students must calculate the momentum of the vehicles before and after the collision and determine whether momentum was conserved.

• Groups must prepare a detailed report explaining their findings and present it to the class.

• Encourage students to use graphs and tables to illustrate their results.

Feedback

Duration: 25 - 30 minutes

📌 Purpose: The purpose of this stage is to consolidate learning through reflection and sharing experiences. The group discussion allows students to review and reinforce the content learned, while the 360° feedback promotes the development of interpersonal skills and a culture of mutual support and growth.

Group Discussion

🗣️ Group Discussion: Promote a group discussion with all students, where groups share what they learned while carrying out the activities and their conclusions. Follow this brief script to introduce the discussion:

Start the discussion by thanking everyone for participating in the activities. Ask each group to present a summary of what they did, describing the challenges they faced and the solutions they found. Encourage students to reflect on how the conservation of momentum manifested in their specific activities. Facilitate the exchange of ideas among groups, promoting collaboration and learning together.

Reflections

1. 🤔 Reflection Questions: 2. What were the main challenges you encountered while applying the concept of conservation of momentum in your activity? 3. How did the use of digital tools assist in understanding the concept of conservation of momentum? 4. After conducting the activities, how would you apply conservation of momentum in everyday situations not covered in class?

360° Feedback

🎯 360° Feedback: Instruct students to conduct a 360° feedback step, where each student must receive feedback from the other members of the group they worked with. Guide them to ensure that the feedback is constructive and respectful, following these guidelines:

Positive Feedback: Start by pointing out something the member did well during the activity. Areas for Improvement: Identify an aspect where the member can improve, offering practical suggestions. Closing: End with a word of encouragement, reinforcing the importance of teamwork and continuous learning.
