1. 2.2 States of Matter: Solid, Liquid, Gas
Active Chemistry

2. Date: 8/29/11 HW: 2.2 CTG, pg. 118, #1-9 Learning Objectives
Describe the molecular motion of different physical states
Success Criteria:
Create an animation to illustrate the behavior of particles in different phases of matter, and as the material changes phase.
Observe changes of state of water and describe the process graphically
Observe a change of state of carbon dioxide and describe the energy transformation involved
Describe the energy transformation and the roles of kinetic and potential energy as heat energy is transferred to or away from a material
Describe the behavior of gas particles, based on your observation of how the temperature, pressure, and volume of the gas are affected as heat energy is transferred to or away from the gas
Characterize materials by their unique phase-change temperatures

3. Do Now WDYS, WDYT p. 110 Start setting up notebook
(for WDYT—write a sentence describing each diagram!)
Start setting up notebook
Parts A, C, and D
Set up a table—30 second increments for 15 minutes
Complete sentence structures

4. Do Now
What are the main differences between a solid, liquid and a gas?
List at least 2 differences
Please write 3 examples of each.

5. Whiteboarding
In the 3 squares, draw as a group what you think the particles look like in a solid, liquid, and a gas.

7. Notebook Set Up Set up numbers 1-9 in your notebook
Be sure to include a data table on one page
30 second increments for 15 minutes

8. Do Now:
Take 5 minutes and make sure you have your notebook set up

9. Investigate Part A: Complete #1 in Notebook
Set up notebook for #2-8, OK with Teacher
Complete #2-8
On a sheet of graphing paper, graph out your points!
Use your data to answer all questions for #9, graph paper will be provided.

10. Do Now
Look at your graph from Weds/Thurs—what are some interesting points?
What is happening in your mind when the graph goes flat?
What is happening when the graph rises?
Use the words ‘thermal’ and ‘phase’ energy in your response.

11. Energy
LOL Diagrams
Thermal Energy (Kinetic motion of the molecules)—Temperature (KE of molecules)
Phase Energy (with phase changes)

12. Whiteboarding
As a group 1) Draw the shape of your heating curve 2) Label the states of matter 3) Label the melting point and boiling point 4) Draw what you think is happening to the energy at each point (where is phase energy, where is thermal energy)

13. Eureka!

14. Investigate
Part C and Part D
Demo
LOL diagram for part D

16. Proficiency Check Draw a quick heating curve for mercury.
Label the x and y axes
Label where the solid, liquid, and gas phases are
Put where you think the heat from the burner is converted to phase energy and thermal energy

17. Do Now: The three states of matter are Solid, Liquid, and Gas.
Between which states of matter the following transitions fall:
Ex: Condensation: Gas  Liquid
Evaporation
Freezing
Melting
Vaporization

18. Vocab Boxes

19. Proficiency Check
Bromine has a melting point at -7.8oC and a boiling point at 58.8oC. Sketch a heating curve for Bromine.
Answer the following questions.
What state is bromine in at the melting point of water? (0oC)
The temperature is lowered to -75oC. Describe the shape as either definite or indefinite.

20. Do Now
Trace this cooling curve in your notebook. Label the parts of the curve that are solid and liquid, and the melting point.
