> Duration: 60 to 70 minutes

- Goal: Combine the digital creation of 3D models with volume calculations to promote practical and relatable learning.

- Deskripsi Activity: In this activity, students will use an online 3D design platform to create cylinder models and calculate their volumes. The task includes both digital creation and applying the formula to validate the designs.

- Instructions:

• Divide the students into groups of up to 5.

• Each group should access an online 3D design platform, like Tinkercad.

• Students must design various cylinders with different dimensions using the chosen platform.

• After creating the models, they must calculate the volume of each cylinder using the appropriate formula.

• Groups will prepare a short presentation to share their models and explain their volume calculations.

• Finally, each group presents their project, highlighting the challenges they faced and the lessons learned throughout.

Feedback

Duration: 15 to 20 minutes

This lesson stage promotes reflection and consolidation of knowledge through practical activities. Sharing experiences and exchanging constructive feedback enriches students' learning, encouraging collaboration and critical thinking.

Group Discussion

Facilitate a class discussion where groups share their experiences and conclusions from the activities. To guide this discussion, the teacher can use the following script:

1. Introduction: Ask each group to briefly summarize the activity they conducted and the context chosen.
2. Practical Application: Request groups to explain how they applied the formula for the volume of the cylinder in their activity and discuss any challenges they encountered.
3. Reflection: Encourage them to reflect on what they learned from the activity and how it relates to everyday situations.
4. Conclusion: Invite each group to share one key insight or conclusion they derived from the experience.

Reflections
