• The challenges will include calculating velocities before and after collisions using the restitution coefficient.

• Scores will be assigned based on the speed and accuracy of responses.

• The group with the highest score at the end of the challenges will be declared the winner.

• Discuss in groups the strategies used to solve challenges and share learnings with the class.

Feedback

Duration: 20 - 25 minutes

This stage of the lesson plan aims to consolidate the students' learning through reflection and collaborative discussion. By sharing their experiences and giving and receiving feedback, students can develop a deeper understanding of the studied concepts, as well as improve their communication and teamwork skills.

Group Discussion

Promote a group discussion with the entire class, where each group shares their experiences and conclusions after the activities. Suggest the following outline to introduce the discussion:

1. Introduction: Ask students to briefly share the activity they conducted and the main results obtained.
2. Comparative Analysis: Ask the groups how the results compare with each other and what differences or similarities they noticed in the different activities conducted.
3. Practical Applications: Encourage students to discuss how the restitution coefficient can be applied in everyday situations and in different professional areas.

Reflections

1. What was the main discovery you made about the restitution coefficient during the activities? 2. How can calculating the restitution coefficient influence decisions in sports and automotive design? 3. What differences did you identify between elastic and inelastic collisions and how might these differences impact the safety and efficiency of objects?

360° Feedback

Conduct a 360° feedback session where each student receives feedback from the other members of their group. Guide the class to ensure this feedback is constructive and respectful, highlighting strengths and suggesting improvements. Suggest questions like: 'What did I do well during the activity?' and 'What could I improve for next time?'
