Weather and Water
Page 83 Vocabulary Due 3/24
Air Pressure
The force exerted on a surface by the mass of air above it
Atmosphere
The layer of gases surrounding Earth. 5 total layers
Permanent Gas
A gas in the atmosphere in which the amount of gas stays constant. Examples: Oxygen and Nitrogen
Variable Gas
An atmospheric gas whose amount changes based on the environment. Examples: Carbon Dioxide and Methane
Air Investigation Page 22
Observations
Write at least three (3) observations when we discuss the air in the syringe as a whole class
Questions
1. Does air have weight (mass)?
2. Where does air pressure come from?
3. How does air push the syringe plunger out?
4. Why is air pressure so strong?

Air Investigation Page 22
Major Concepts To Remember
Compressed air pushes back with a force equal to the force compressing it. This push is called
pressure
Molecules compressed into a smaller space bump into one another more often, and this creates pressure
Air has mass
Air moves from areas of high pressure to low pressure.
Climate vs. Weather Page 19.
Hypothesis
Predict what the difference between climate and weather is.

Predict how one impacts the other.
Weather vs. Climate
Bill Nye Atmosphere
Layers of the Atmosphere
Atmospheric Layers Partner Activity Page 24-28
Directions
1. Open to page 24-28 of the textbook. Stable handout into notebook on page 23.
2. Each partner must fill in two facts for 3 layers of the atmosphere. (3 Layers Each Person = 6 Total Layers and 12 total facts)
1 additional fact will be added during the video review
3. Look For:

Average Temperature
Is the air thin or thick
Space
Greenhouse Effect
Pressure in a Jar Lab Page 26
Pre-Lab Info Review and Question

Earth's atmosphere has multiple different layers with unique (different) features.
We have learned so far that....
Pre-Lab Question answer on bottom of 26...

c. Compression will destroy all the particles

a. There was less empty space in the jar which causes more particle collisions
b. Squeezing the jar destroys the particles
c. There was more empty space in the jar which causes more particle collisions
d. Our air pressure remained the same while we squeezed the bottle.
Weather and Water Quiz #1 Review
Expectations
I'll read the question aloud twice
Place the clothespin on the letter you think the answer is
Hold up your answer for me to see
No yelling out answers (LDT)
No playing with the clothespin (LDT)
When we finish connect the clothespin to the paper and leave them sitting on your desk
Weather and Water Quiz #1 Review
Question 6

b. Thermosphere
c. Troposphere
d. Mesosphere
Pressure in a jar lab
Post-Lab Key Idea
When we squeezed the jar we reduced the amount of space the particles had to move around. This caused them to collide more which resulted in more pressure causing the water to go down.
Surface Air Pressure Map Page 32
Directions
Begin drawing from the 1020 millibars station pressure over Utah. Draw a line to the next 1020 value located to the northeast. Without lifting your pencil draw a line to the next 1020 value located to the south-east and then to the two located southwest, returning to Utah.
Complete the rest of the map the same way using the different numbers.
Term 6 Vocabulary #1 Due 4/14
Fluid
Substance that can flow, such as a gas or liquid
Convection
Heat transfer in a fluid in which hot fluid rises and cold fluid sinks, setting up a cycle
Convection Cell
Mass of fluid flowing in a cycle in an area
Absorb
To soak up
Greenhouse Gas
A gas that absorbs and radiates heat energy in the atmosphere, effectively trapping heat
Surface Air Pressure Map Page 32
Key Ideas
In meteorology, air pressure is measured in
bars
.
The unit usually used to measure atmospheric pressure is the
millibar (mb).

Atmospheric Pressure and Air Pressure are the same concept
Surface Air Pressure Map Page 33
Hypothesis
In nature air flows freely. What happens when two areas of air have different pressures?
Surface Air Pressure Map Page 33
Post Activity Questions
1. What do you think it means when the isobar lines are closer together?
2. What do you think it means when the lines are farther apart?
3. What could the distance between isobars tell us about how fast the wind is blowing?

Surface Air Pressure Map Page 33
Post Activity Answers
1. The air pressure is changing a lot over a very short distance.
2. The air pressure is changing slowly over a greater distance.
3. Wind speed will be the highest between locations where the isobars are close together.
Poster Board Organization
Groups
I will give you 1 minute to form groups of 3. I will have the final say into who works together based on this years performance/behavior.
When the stopwatch goes off you should be sitting with your group members. After that zero movement without my permission.
Depending on the numbers we may need to create groups of 2 or 4.

Density Review
Density determines the order of the materials as they settle or deposit.
The densest material would sink to the very bottom and the other materials would layer on top of that in order to decreasing density.
T
he layer on the top is the least dense.
Density
The amount of mass in a material compared its volume

Questions
Convection Review Page 43
The heat transfer in a fluid in which hot fluid rises and cold fluid sinks, setting up a cycle
Heat always moves from a warmer place to a cooler place.
Hot and Cold Water Experiment
Weather and Water Connection
As matter heats up, it expands, causing the matter to become less dense.
Warm air rises and cold air sinks.
The mass movement of warm air upward is convection.
Page 42 Practice Problem
Convection/Density in Weather
Directions
Answer on page 43 of your notebook
How does heat affect density of fluids?

Name what you think are the two ways to change the density of substance.

How does density impact weather and air movement?
HOT AIR IS LESS DENSE THAN COLD AIR. WHEN THEY MEET EACH OTHER IT IS CALLED A
FRONT
.
Convection/Density in Weather
Answers
Heat will decrease the density of an object

The two ways to change the density of a substance are by physical force, like air in a syringe, and by adding or removing heat

Hot air (less dense) on top cold air (more dense) on the bottom.
