1. Intro to Matter, Physical and Chemical Changes

2. Common Core Connection
Objectives
Today I will be able to:
Identify matter as an element, compound or mixture
Differentiate between chemical and physical properties and changes
Informal Assessment – monitoring student interactions as they complete the practice
Formal assessment – analyzing student responses to the warm up, exit ticket and practice
Common Core Connection
Reason abstractly and quantitatively
Use appropriate tools strategically

4. Warm - Up
28.50 g of iron shot is added to a graduated cylinder containing 45.5 ml of water. The water level rises to the 49.1 ml mark. From this information, calculate the density of the iron.
Identify the following as an element, compound or mixture
Gold
Lemonade
Salt

5. Objective Today I will be able to:
Identify matter as an element, compound or mixture
Differentiate between chemical and physical properties and changes

9. Chemical and Physical Changes and Properties

10. Physical Properties
An aspect of matter that can be observed or measured with out changing it
Intensive Properties – do not depend on the amount of matter present (density, boiling point, freezing point, color, odor)
Extensive Properties – depend on the amount of matter that is present (mass, volume, pressure, length)

11. Chemical Properties
Enables a substance to change into a brand new substance, and they describe how a substance reacts with other substances
Flammability
Reactivity

12. Changes in Matter
Through experimentation and natural occurrences, matter tends to change in either of two ways
- Physical Changes
- Chemical Changes

13. Physical Changes Only physical properties change
The form of matter changes, but the identity of the matter remains the same
Examples: change in state (phase change), breaking a pencil, tearing paper

14. Physical Changes
Phase Change – physical process in which one state of matter is transformed into another

15. Physical Changes

16. Chemical Changes
Properties of original substance disappear as new substances with different properties are formed
Change in chemical composition
Cannot return to original form
Can be detected through – energy changes (temperature), change in color, emission of gas, solid formed
Examples – wood burning, iron rusting, sour milk

17. Examples – Chemical or Physical Change?
A match lights when struck
Wood is placed into a chipper
A lump of gold is pounded into a large, thin sheet
Baking powder bubbles and gives off CO2 when it is moistened
A pan of water boils on the stove
Hydrogen Sulfide gas causes silver to tarnish

18. Chemical and Physical Changes Practice
Complete the practice at your desk. Whatever you do not finish will become your homework

19. Exit Ticket Watch the following clip
Decide if this is a chemical change or a physical change. Explain why
