Name all the oceans in order of smallest to largest:
Pacific, Atlantic, Indian, Arctic

Why did your cups only have salt left in them at the end? What was the process that made that happen? What did it do to the salinity?
The water evaporated, leaving the salt behind. The salinity rose because there was more salt compared to the little amount of water (if any) that was left. Salt stays and water leaves.

What happens to the pressure when molecules change state from a solid to a liquid?
they speed up and spread out
100
What is it called when something goes from a solid directly to a gas, or a gas directly to a solid?
Sublimation!
200
What is the proper definition of salinity:
the amount of dissolved salt in water

Tell me what an independent variable means.
This is what you’re changing in the experiment. For example, in part 1 with the salt cup on the heat register, what did we change?

How does the pressure of the atmosphere change as you go up in altitude (go higher up)?
The higher you go, the less pressure there is on top of you. You leave it below you.

Draw, with labels, the water cycle
Show me!

Please name, in order starting from the shore and going out into the ocean the layers of the CONTINENTAL MARGIN
This is what is changing because of the independent variable. It DEPENDS on the independent variable. For example, in part 1 with the salt cup on the heat register, what was the depended on the Independent variable?

Lets say we have a piece of dry ice, we weighed it, then placed it in water; a gas came off of it. What if we were to capture ALL of the gas that came off the ice chip and weigh it, how would it compare to the original weight of the ice chip?
They would weigh the same because matter cannot be created nor destroyed!

What are the four forms of precipitation? And, how old is the water that comes out of this tap? (A general “it is as old as ______ “ would be okay) You have to get both right
o snow, sleet, rain, hail
o As old as the Earth
400
What are tides caused by and when would the highest tide be? (hint: I’m not talking about the time of day, think much, MUCH bigger scale)
the Moon
highest tide would be when the sun and the moon are aligned together both pulling on the Earth’s oceans.
400
What did we test when we put one cup on the heat register and one by the cold window?
The rate of evaporation

Write a hypothesis for an experiment using dry ice, a balloon, and a beaker with some water in it.
If I put the dry ice and the beaker and put the balloon over top of it, then the balloon will blow up because the gas that the dry ice gives off expands and needs somewhere to go.

Where do icebergs come from?
Continental Glaciers, or Icecaps, or Glaciers, or the Poles
500
What causes ocean currents?
Cold water moving from the cold areas to the warm equator and then cooling off and going back to the poles.
500
What are the components of the summary?
What did you learn?
What could you change to improve the experiment?
What were the sources of error?
500
Why did the pop can implode (crush) when we heated it up and then turned it over and placed it in the cold water?
the hot water molecules inside the can were moving VERY fast and then they were cooled very quickly when we put it in the cold water causing the molecules to slow down and come together.

Describe for me what polarity means? Name a molecule, NOT ELEMENT, that has polarity. Have to get both right to get the points.
Polarity is when a molecule has oppositely charged ends. Water is an example

Pick any experiment you want and write me a perfect, and I mean PERFECT hypothesis. It could be anything (appropriate only) that you'd like.
It needs to have all the components of a hypothesis that we discussed in class to get the points.
