STANDARD 1 DESCRIPTION: Matter can be described using it’s physical and chemical properties. Chemical properties must be determined by an actual test to
see if a new substance is formed. Physical properties can be determined without changing the substance. Matter can also be changed physically or chemically.
During a physical change the matter is still the same substance. During chemical changes atoms and molecules are rearranged and new substances are created.
Even though during a chemical change mass is conserved. This means the types and number of each atom that goes into the reaction will come out of the
reaction. This is true even though they are rearranged into new molecules. Chemical and physical changes can be identified by observable events. Chemical
change indicators appear almost magic. They may release light, heat, a new odor, or even appear to loose mass. This apparent lost mass occurs in open systems
and is simply mass, usually gas, escaping into another system. Physical changes include phase changes. An example is when water can change form solid, to
liquid, to gas, and finally to plasma. It is still H2O but the motion of the molecules has changed and thus changes the state of the water.

QUIZ 1 : a.) Differentiate between chemical and physical properties.
b.) Classify substances based on their chemical and physical properties (e.g., reacts with water, does not react
with water, flammable or nonflammable, hard or soft, flexible or nonflexible, evaporates or melts at room
temperature).
VOCABULARY
1. chemical properties: a characteristic that explains how a substance has the potential to be changed into
another substance.
2. physical properties: Property of a compound that can change without changing the substance
3. reacts : Describes the potential of one substance to interact with another substance and create a new
substance

QUIZ 2: (ERIC) a. Identify observable evidence of a physical change (e.g., change in shape, size, phase).
b. Identify observable evidence of a chemical change (e.g., color change, heat or light given off, change in odor,
gas given off). Identify the kinds of energy (e.g., heat, light, sound) given off or taken in when a substance
undergoes a chemical or physical change.
VOCABULARY
4. Chemical Change Indicator: Any observable event that shows a new substance has been created.
5. Physical Change Indicator: Any observable event that shows the original substance is still present.
6. Physical Change: A change where the atoms are in their original arrangement and the original substance is
still present.
7. Chemical Change: A change to matter where the atoms have been rearranged and a new substance has
been formed.

substance. Measure and graph the relationship between the states of water and changes in its temperature.
VOCABULARY
15. Boiling/Vaporization point: The temperature at which a liquid changes into a gas. For water 100⁰ Celsius.
16. Melting point: The temperature at which a solid changes to a liquid. For water 0⁰ Celsius.
17. Freezing point: The temperature at which a liquid changes to a solid. For water 0⁰ Celsius.
18. Condensation: The process of a gas turning a gas to a liquid. For water 0⁰ Celsius.
19. Sublimation: The process of going from solid directly to a gas.
20. Phase Change: The process of changing states. The temperature does NOT change during this process.
