4. Objectives-
|
1.Define and Compare thermal energy and temperature
2.Relate changes in thermal energy to changes of state
3. Explore energy and temperature changes one graph |
| |
|
5. Materials and Aids-
|
1.Powerpoint
2.Worksheets
3.Reading Material |
| |
|
6. Procedures/Methods-
|
|
A. Introduction-
1. Make predictions of what you think the vocabulary words mean
without reading the actual meaning of it.
3. Review what the students know about States of Matter and what they
believe "Changes of State" mean. |

|
|
B. Development-
|
|
C. Practice-
Read: Visualizing States of Matter/ During the melting and vaporization
process the temperature remains constant. Look at the graph and identify
which factor continues to increase. (Thermal Energy)
What changes in molecular attraction occur as water goes from a solid
to a liquid to a gas? (As a solid, the molecules have the most attraction
for each other. As a liquid, the molecular attraction has decreased.
As a gas, there is no longer any molecular attraction between the
molecules.
During condensation, what must be removed from the gas to become a
liquid? (Thermal energy) |
| |
|
|
D. Independent Practice-
| Write a letter about the life of a water molecule as it goes from
a solid to a gas. How free and what it see as a molecule that's part
of a solid, liquid, or vapor. |

|
F. Checking for understanding-
Class Survey
1. How would you rate this weeks lesson on a scale from 1-10 ? (With
10 being the highest)
2. How would you rate your understanding of the material?
3. What can be done to give you a better understanding of the material?
4. What part of the Section 1 & 2 don't you understand. |
