Heating and Combustion Experiments: Use crucibles to heat small amounts of solids, such as salt or metal powders, to observe chemical changes during high-temperature reactions.
Dehydration Reactions: Demonstrate water loss in hydrated salts like copper sulfate by heating them until they turn from blue to white.
Ash Content Analysis: Burn organic materials (such as leaves or paper) to show how only inorganic ash remains after combustion.
Melting Point Demonstrations: Test the melting points of small metal samples or other materials.
