  1. PART 1: WHAT IS A PHYSICAL PROPERTY? 12/3/2013 • Based on the words PHYSICAL PROPERTIES, what do you think a physical property is? • Description of an object using characteristics that can be observed using your senses or measurement equipment. YOU DO NOT CHANGE THE OBJECT’S IDENTITY AT ANY TIME! • How do PHYSICAL PROPERTIES compare and contrastto CHEMICAL PROPERTIES? • Physical properties can easily be seen. You DO NOT change the identity of the object. • Chemical properties cannot be easily seen. You DO change the identity of the object because you have to have a chemical reaction happen to observe the property. • Examples of PHYSICAL PROPERTIES are: mass, weight, volume, density, state/phase of matter, malleability, ductility, conductivity, brittleness, luster, melting point, boiling point, evaporation point, color, smell, shape, size, etc….

  2. PART 2: PHYSICAL PROPERTIES AROUND THE ROOM: (12/3/2013) • (CREATE CHART ON LEFT HAND SIDE) • In your group pick 6 objects that you want to examine and list them below in the correct column in the chart. • Once you have agreed on 6 objects, list the properties of the object you feel are physical properties.

  3. PART 3: WHAT IS A PHYSICAL CHANGE? 12/3/2013 • Based on the words PHYSICAL CHANGE, what do you think a physical change is? • Any change to the physical properties of an object; meaning you are changing their appearance NOT their identity • How do PHYSICAL CHANGES compare and contrastto CHEMICAL CHANGES? • Physical changes only change the object’s appearance; not it’s identity • Chemical changes change the object’s identity; hard to get starting substance back. • Examples of PHYSICAL CHANGES are: changes of phases, ripping paper in half, mixing lemonade powder in water, melting a candle, shaping clay into a dog, etc… (just a few, there are more),
