During Mr. Pieniazek's "Deep Ocean Current Demo" what was the purpose of the green dye?
To help us see and visualize the current
During Lab 7 we blew onto the surface of the water through a straw to model surface ______
wind (it made a surface current!)
Salt water is ______ dense than tap water.
MORE
What is the vocabulary word for the definition: "Moving Air"
Wind
The higher the salinity, the greater the ___________.
density
What gets the MOST direct sunlight:
A. The poles
B. The equator
C. Middle latitudes
The equator
Did the craft stick on the barometer go above or below the baseline on a high pressure day?
Above
During the salinity egg demo, the egg __________ in the tap water because the egg was was ________ dense than the tap water.
(Unless it was rotten, haha)
sunk; more
What is a barometer?
It is a tool that measures air pressure.
What are TWO properties (things) that FUEL deep ocean currents?
Density differences in ocean water and temperature difference in ocean water
During the temperature lab, the dyed blue cold water ________, but dyed red warm water __________.
sunk; rose/floated
What is the relationship between altitude and air pressure in earth's atmosphere?
As altitude increases, pressure decreases.
As altitude decreases, pressure increases.
As you go deeper into the ocean, water is _________ and ________ salty.
colder; more
A maritime air mass near the poles would most likely be:
A. Cold and wet
B. Hot and wet
C. Cold and dry
D. Hot and dry
A. Cold and wet
What are the two types of ocean currents?
surface currents and deep ocean currents
Warm water ________ because it is __________ dense than colder water.
rises; less
What type of weather did we generally see on a LOW pressure day? (name at least 3)
Something along the lines of overcast skies, cloudy weather, foggy, misty, rainy, "lousy weather"
How does the words salinity and density relate to one another? Give a real world example!
The higher the salinity the greater the density.
The lower the salinity the lower the density.
Real world example: Salt water is more dense than tap water, so objects in salt water are able to float easier since they may be less dense than the salt water around them.
During Lab 5 Cloud in a Bottle, what happened to pressure when the bottle was squeezed? What about temperature? Lastly, what did we see when the bottle was squeezed?
Pressure increased
Temperature increased too!
Since temperature increased the water in the bottle evaporated into a gas so we DID NOT see a cloud.
Pressure always goes from _____ pressure to ______ pressure.
Also give an example of what weather would be like on a high pressure day.
High pressure to Low pressure
Examples for what we may see on high pressure weather days: Clear skies, windy, sunny and dry, no precipitation.
Have your table group come to the board. Draw the current we saw in our petri dish from Lab 7 and explain how the water/powder moved within the dish.
**Don't forget to label where your straw was!
Drawing should show something like the picture Mr. Pieniazek drew in his science notebook (you can see this on google classroom)
The water/powder moved away from the wind, hit the back of the petri dish, and then flowed back towards the straw where it was blown forward again.
2 circles form on the outside of the center, both swirling in opposite directions.
During the salinity lab we poured 100mL of super salty green water. We then carefully poured 100mL of tap water on top of it. Then, you squeezed a few drops of slightly salty red water into the bottom super salty green layer.
Where did/should have the red water ended up and why?
The red drop should have floated up and settled in the middle. This is because the slightly salty red water was more dense than the tap water, but less dense than the green salt water.
Have your team come to the front white board. Draw two pictures to illustrate the difference between a sea breeze and land breeze.
Use arrows to show where the breeze comes from and color code it: RED = warm, BLUE = cold.
Seabreeze diagram should show cool air coming from the ocean to the land during the day. (warm air from land going to ocean)
Landbreeze diagram should show cold air coming from the land to the ocean during the night. (warm air from ocean going to land)
During Lab 4 "When Air masses meet" there were 3 trials we conducted in the convection tubes.
Explain what happened in one of the three trials and what was made inside of the convection tube.
Ice and ice: smoke sunk near ice side and did not move to the other side of the convection tube.
Ice and hot water: smoke sunk near ice and then made it's way to the hot water side and rose out of the top. Wind (moving air was created)
Ice and candle: smoke sunk near ice and very quickly moved to the side with the lit candle and smoke went out the top. Wind (moving air) was made.
