3. Physical & Chemical Characteristics PHYSICALCHEMICAL Changes its appearance physically Changes what it is made up of (changes the atoms to make a new thing); reacts

4. Properties What is a property? Describes, talks about it’s ability to… Can be physical or chemical Has it CHANGED yet?.... NO Does it describe it/have ability to change?

5. Examples of Properties Front Desk: PHYSICAL PROPERTIESCHEMICAL PROPERTIES

7. Changes When it actually changes Physical: changes size, shape, but its still the same thing Chemical: changes what it completely is, chemical reactions

8. Examples of changes Tearing paper Burning paper Breaking wood Campfire Mixing kool aid Cooking a cake Physical change Chemical change

9. Property vs. Change Property = description or could change in the future Change = change 5 evidences of a chemical change PCOGT – “Pirates can obtain great treasures” – Precipitate (solid forms) – Color change – Odor(smell) – Gas forms – Temperature change – Evidence of a chemical change Evidence of a chemical change – http://resources.educ.queensu.ca/science/main/concept/gen/g09/N.%20Sabet/precipitation.jpg
