A characteristic of matter that is either observable (qualitative) or measurable (quantitative). Examples: Weight Color Hardness Smell Temperature Density

A characteristic of a substance that describes its ability to participate in chemical reactions. Examples: Flammability Color Change Temperature Change Fizzing and Bubbling

Metal 1 2.7cm long Metal 2 4.4cm long

Identity of Metal 1 is : Aluminum Supporting Evidence: Aluminum is a lighter color than Metal 2 Aluminum is softer than Metal 2 Aluminum is a Non Magnetic metal Resources: Georgia Holt Science and Technology Physical Science Text Book

Identity of metal 2 is steel Supporting evidence: Steel is harder than aluminum Steel is magnetic aluminum is not magnetic Resources: Georgia Holt Science and Technology Physical Science Text Book

There were three possible liquids, and each one reacted differently when it came in contact with a flame. Water Rubbing Alcohol Vinegar

Mystery Liquid: alcohol Supporting evidence:  The liquid is flammable  The liquid had the same odor as the alcohol Resources: prior experiments and the Holt Science and Technology Physical Science Text Book

 There were four different powders: Baking soda, baking powder, baby powder, and corn starch Baking powder Baking soda Corn starch Baby powder Mystery powder

Mystery powder: baking powder Supporting evidence:  Reacts with water, vinegar, and iodine  Bubbled when it came in contact with water and vinegar  Turned the iodine black  Resources: Knowledge from prior experiments

We conclude that the Metals found at the SWAM crime scene were: aluminum, & steel The liquid was: alcohol The powder was: baking powder
