Science Lab Experiment: Properties of Three Elements
Demonstration: Characteristics of Three Elements
Object: To determine the characteristics of three elements: calcium, phosphorus, and sulfur
Materials: phosphorus, calcium, sulfur, long-handled spoon, beaker, alcohol lamp, matches
Method A piece of white phosphorus was exposed to the air. Sulfur was heated using a special
long handled spoon. A piece of calcium was added to water.
Observations: The phosphorus burst into flame when exposed to air. The yellow sulfur burned
with a blue flame and had a choking odour. The calcium smoked, moved violently and
disappeared. The water turned cloudy, indicating that a chemical reaction had taken
Conclusions: Characteristics of three elements were determined. An element has one kind of
atom and has its own characteristics.
