At Templer Park International School Rawang (TPIS), our G10 students conducted two separate experiments to deepen their understanding of heat and particle behavior.

In the first experiment, students explored how different states of matter respond to heat. By heating air inside a balloon, they observed it expanding as gas particles move faster and push outward. They compared this with a solid object, like a marble, discovering that while solids do expand when heated, the change is so tiny it’s not visible without precise instruments.

In the second experiment, students investigated the thermal conductivity of different metals. By placing metal strips in hot water, they examined how heat energy transfers through conduction—where particles vibrate and pass energy along the material. This allowed them to compare how effectively different metals conduct heat.

Two different experiments, one clear takeaway: heat affects materials in fascinating ways, from particle movement to energy transfer.
