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? – PHYSICAL PROPERTIES ARE: 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 contrast to 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. OBJECTPHYSICAL PROPERTIES 1 2 3 4 5 6

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? – PHYSICAL CHANGES ARE: any change to the physical properties of an object; meaning you are changing their appearance NOT their identity How do PHYSICAL CHANGES compare and contrast to 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),
