On Monday, February 17, 2025, Suan Sunandha Rajabhat University Demonstration School organized an integrated activity for 5th-grade students. The activities focused on Unit 5, which is about smart innovations, and Unit 6, which is about sound-producing media. The students were tasked with creating a model of a truck to study the concepts of thrust and friction, applying these concepts to everyday life. They also created a model of a sound-producing device to explore sources of high and low sounds. The students collaborated in brainstorming and crafting their projects, observing the results, and were able to take their experiments home to continue testing.
