Sugar can melt without yet becoming caramel
Heat pure white sugar in a pan, and it first melts into a clear syrup before suddenly turning amber and developing a rich, nutty aroma. That second stage is caramelization: high heat breaks sugar molecules apart and recombines them into hundreds of new flavor and color compounds, taking the transformation far beyond a simple physical change from solid to liquid.
Questions you could explore
- How is melting different from forming new compounds?
- Why would one temperature not describe caramelization in every mixture?

The Institute of Food Science & Technology explains caramelization through changes in heated sugars; a practical hot-sugar experiment is not required.
