Year 5

Alumni Session about the Ocean

On December 5th, 2025, Year 5 had a very special experience. We were visited by three guest speakers; Kirana Agatha Gusasi, Rachel Adelheid Kanter and Luthfi Haidar Adriananta. Two of whom were students at Global Jaya School just two years ago. They are from Binus University working on a project to support the world environment. 

They talked about oceans and how we can help save them. This learning connected perfectly to our current unit, “Sharing the Planet,” where the students explore how people can restore various habitats, including rivers, oceans, mangroves, coral reefs, and forests. Listening to their presentation helped us understand that saving the ocean is not only the job of adults, but kids can help too.

The guest speakers also showed us how to present more confidently, speak clearly, face the audience, make eye contact, and avoid reading from the slides.

Overall, the visit was inspiring, educational, and very helpful. We learned more about the ocean, how to restore habitats, and how to become better presenters. We are thankful that the guest speakers took the time to teach us, and we hope to use what we learned to make a positive impact on our planet.

Restoration Presentation

Under the unit of "Sharing The Planet," the Year 5 students had a presentation about restoration, showing their understanding of how people can take action to repair and protect the natural world. Some of the Year 5 students had different topics, such as coral reefs, mangroves, rivers, forests, or the ocean, and explained why it is important for human life and what steps we can take to help restore it. The students were allowed to present in any way they wanted. Some students created posters or slides, while others chose creative formats such as videos.

The students explained how restoring ecosystems helps communities adapt, stay healthy, and build a sustainable future for everyone.

We hope their projects inspire other year levels and our school community to take small but meaningful actions to care for our planet.

Understanding Kinetic Energy Through Hands-On Experiment

In our recent science lesson, the Year 5 students explored how kinetic energy changes and how energy is transferred during a collision. Working in groups, they tested a simple science experiment. Each group chose a variable to change, such as ramp height or ball mass, and observed how this affected the movement of the other object.

Students recorded their data carefully and used it to write a Claim–Evidence–Reasoning (CER) explanation. They discovered that when an object moves faster or has more mass, it carries more kinetic energy. During a collision, some of that energy is transferred to another object, causing it to move.

Through this experiment, students practiced collecting data, making observations, and applying scientific ideas to explain what they saw. They also connected their learning to real life, recognizing examples like kicking a soccer ball, riding a bike, or pushing a swing. This hands-on activity helped students understand energy transfer in a clear and engaging way.
