  2D, 3, 3A, 7, 7A, 8, 8A
• Objective Explain parts of kinetic theory and
  particle movement in matter.
• Engage Split Pea CD Cases and Brainstorm.

3

• Explore Ice Cream Phase Change
• Explain Solids, Liquids, Gases, Phase Change
  Chart, and Kinetic Theory

4
In reaching the boiling point of a liquid, what
is the relationship between time and temperature
of various volumes of the liquid?

• Independent Variable time
• Dependent Variable temperature
• Purpose To see that it takes time to get the
  particles moving.

5
Elaborate Data
Average Time and Temp of Various Volumes
6
Results/Conclusions

• An increase in Volume caused the water to take a
  longer time to reach boiling point of 100OC.
• Therefore it takes time to get the particles
  moving fast enough to vaporize.

What is the relationship between mass and density
of cubes with 2½ cm sides?

• Independent Variables Mass
• Dependent Variables Density
• Purpose Students can connect mass to density.

11
Elaborate Data
12
Results/Conclusions

• As the masses of the different cubes increased
  the density increased.
• Density has a connection to the mass of the
  object.

What is the relationship between temperature and
time for a ball to go through a fluid?

• Independent Variables Temperature
• Dependent Variables Time
• Purpose To see the effects of viscosity.

17
Elaborate Data
18
Results/Conclusions

• As the temperature increased, the marble fell
  faster through the honey.
• The viscosity of a liquid is affected by the
  temperature of the liquid.

What is the relationship between temperature and
volume of a balloon?

• Independent Variable temperature
• Dependent Variable volume
• Purpose See the direct relationship of Charles
  Law.

23
Elaborate Data
24
Results/Conclusions

• As the temperature decreased, the volume of the
  balloon decreased. As the temperature increased,
  the volume of the balloon increased. This is a
  direct relationship.
