1. The document describes a procedure to observe colored flames using different chemicals. 2. Materials needed include calcium, sodium, boron, copper, potassium, methanol, lighter, and six glass plates. 3. The procedure involves placing the heel in glass plates, adding chemicals to each plate, lighting each plate on fire with a lighter, and observing the changing colors of each flame.
