Make 4 lists-physical properties, chemical properties, physical changes and chemical changes. Then put words from the scenario in the proper list. Scenario:

Sodium is a silvery-white, highly reactive metal. Chlorine is a yellow-green gas. When they are mixed together they react with one another to form chemical compound called Sodium chloride (salt). The reaction is exothermic, producing a bright yellow light and giving off heat.

Salt is soluble in water. Salt will give water a greater density and decrease the boiling point of water.
