1.  What is matter?  
Provide 3 examples of matter in our classroom.

2. 2.  Matter is composed of extremely small particles, too small to be seen with a classroom microscope, called __Atoms__________.

3. 3. Draw an example of an atom
3.  Draw an example of an atom.  Be sure to identify the three parts and their charges.

4. Carbon, Hydrogen, Oxygen, and a lot more
4.  Atoms are the smallest part of an _Element_that has the chemical properties of the _____Element_______.  Provide 3 examples of these from the periodic table.  
Carbon, Hydrogen, Oxygen, and a lot more 

5. 5.  What is the periodic table?  How is this arranged?
The periodic table is an arrangement of the chemical elements, organized on the basis of their atomic number (number of protons in the nucleus).

8. 8. _Solubility___ is an example of a chemical property
8.  _Solubility___ is an example of a chemical property.  This property means that the amount of __Solute_________that can be dissolved in a specific volume of ___Solvent________ under certain conditions. Identify the conditions which can affect this.
A-A solute’s solubility depends on the chemical nature of the solvent.
B-Another important factor that influences solubility is the temperature of the system
C- The most common solvent is water

9. 9.  What is density and its formula?
Density=mass/volume
D=m/v

10. Container1- solid Container 2- gas Container 3- Liquid
10.  There are 3 states of matter.  What are they?
 Using the pictures below, identify the states.
Container1- solid
Container 2- gas
Container 3- Liquid

11. 11.  A substance in a __solid_______phase are relatively rigid, has a definite volume and shape. The atoms that comprise a __solid________ are packed close together and are not compressible. Because all __solids__________ have some thermal energy, its atoms do _vibrate_________. However, this movement is very small and very rapid, and cannot be observed under ordinary conditions. When heat is added a __solid________can become a __gas________.

12. 12. __liquids________have a definite volume, but are able to change their shape by flowing. _liquids________ are similar to solids in that the particles touch. However the particles are able to move around. Since particles are able to touch the densities of _liquid________ will be close to that of a _solid______(water is a special exception). Since the _liquid__________molecules can move they will take the shape of their container. When heat is added a _liquid_________can become a _solid_________.

13. 13. _gases________have no definite volume or shape
13. _gases________have no definite volume or shape. If unconstrained __gases_______will spread out indefinitely. If confined they will take the shape of their container. This is because _gas_______particles have enough energy to overcome attractive forces. Each of the particles are well separated resulting in a very low density.

14. 14.  _heat______energy is in the motion of molecules in the phases of matter. Atoms and molecules are perpetually in motion. _increased__________temperatures means the greater average energy of motion so most substances expand when heated. __decreased____________temperatures means the lesser average energy of motion so most substances will contract when cooled.  Most substances can exist as a_solid_______, __liquid_______, or _gas________depending on temperature.

15. 15. Label each of the following transformations:
15.  Label each of the following transformations:
Solid → Liquid =Melting
Liquid → Solid  =Freezing
Liquid → Gas  =Evaporation
Gas → Liquid  =Condensation
