True or False:
Particles are always moving, but the speed of the particles can be different
True
Warm: Particles move faster
Cool: Particles move slower

Some of the ammonia molecules move or travel through air
300
What are the 4 rules Ms. C has in class?
1. Respectful

Below you are defining each as what it represents as a CO2 balloon.
1. The little purple circles represent:
2. Which model is a balloon that is warm?
3. The speed or arrows of the little purple circles represent:
1. Air particles/ Molecules
2. Larger balloon
3. Speed/ movement of molecules
400
What does this model not show or how is it different from a real atom?
It does not show that ammonia is made of millions of molecules. Atoms are not different colors. It does not show that atoms move.
400
Why do different substances have different odors?
*Hint: Think about the lab we did when we had to smell different odors, what made them different from one another?
Different substances have different odors because the atoms combine in different ways (or each has a different arrangement).

When exiting the classroom every student needs to do what before they leave?
Push in your chair and ensure your area is clean before leaving
500
What are the 2 ways that you are able to tell elements apart from each other
- Properties
- Made up of different atoms
500
What are the 4 things to notice when a balloon is heated and cooled?
1. Temperature
2. Size
3. Speed of atoms
4. Number of atoms
500
How is a menthol molecule similar and different to a myrcene molecule?
Similar:
They are both made of carbon and hydrogen atoms.
They have a somewhat similar shape, but not exactly.
Different:
The menthol molecule has an oxygen atom while the myrcene molecule does not.
The carbon atoms are in a ring in the menthol molecule while the carbon atoms in the myrcene molecule do not quite make a ring.

Use your model to explain to your friend how the ammonia in this activity behaved in the two conditions. Choose all that apply.
A. The ammonia particles in the hot water bath reached the indicator paper faster than the molecules in the cold water bath.
B. The ammonia particles in the hot water bath reached the indicator paper slower than the molecules in the cold water bath.
C. The evidence for this is that the indicator changed color slower over the hot water bath, indicating that the molecules that make up the ammonia had traveled up and out of the flask as they were heated and turned from gas to liquid.
D. The evidence for this is that the indicator changed color faster over the hot water bath, indicating that the molecules that make up the ammonia had traveled up and out of the flask as they were heated and turned from liquid to gas.
A, D
