Lovely activity, not for the faint hearted.
Give students a selection of materials which they examine and describe simply.
They then (with the required H&S) heat the material/object using a bunsen(roaring or yellow...you decide), tongs, observe and describe the material afterwards.
I have done this expt using tea light candles in a classroom, with bench mats and an extra pair of eyes it worked beautifully.
This promotes many aspects of chemical changes, durability, suitability etc etc of materials for specific tasks
