In a hands-on investigation filled with curiosity and discovery, our CIE 3 learners explored how different solids respond to heat. With stopwatches in hand, they observed the transformation of ice, butter, and chocolate—from solid to liquid—as each sample was gently warmed.
The results were surprising: ice melted first, followed by butter, while chocolate was the slowest to change. Through careful timing and comparison, learners uncovered the concept of melting points—the unique temperature at which each material begins to melt.
What seemed like a simple experiment revealed a deeper scientific truth: heat affects materials differently, and not all solids melt the same way.
This activity strengthened learners’ understanding of phase changes and introduced them to the idea that every material behaves according to its own properties. It was a vivid demonstration that even everyday objects can teach powerful scientific lessons—if we look closely enough.
“Even the hardest things change when the heat is right.”
