This property of water allows a pin to float on the surface of water.
What is cohesion at the surface (surface tension)?
100
This is the number of hydrogen atoms in a water molecule..
What is two?

How do we calculate the density of an object or substance?
What is divide it mass by its volume?

A student is recording the volume of a liquid. What unit of measurement will she use?
What is liters?

How many different ocean zones did we learn about based on the ocean salinity and temperature?

What is 3?

200
This property of water demonstrates the attraction of one water molecule to another.
What is cohesion?
200
This is the number of oxygen atoms in a water molecule.
What is 1?

In the lab, what tools are commonly used to measure mass?
What is a scale or double beam balance?
200
In the lab, what tools are commonly used to measure volume?
What is a beaker or graduated cylinder?
200

What is the top layer called which temperature and salinity change frequently due to it's direct contact with the air? 

What is the surface mixed zone?

300
This property of water allows water to "climb" up substances.
What is capillary action?
300
This is the chemical formula for water.
What is H20?
300

What is the bond that forms between two or more water molecules?

What is a hydrogen bond?

300
This unit of measurement is used to label mass.
What is grams?
300

What is the bottom layer called where the water remains cold and dense?

What is the deep zone?

400
Water molecules tend to "stick" together because of positively and negatively charged "ends" of the molecule. So, we say it is what kind of molecule?
What is a polar molecule?
400
This refers to the movement of molecules from an area of higher concentration to an area of lower concentration. We observed it in the "All Mixed Up" lab.
What is diffusion?
400
This is formed when two or more atoms combine. For example, water is one.
What is a molecule?
400
This is how density is labeled.
What is g/ml or g/cm3?
400

What is the name of the zone in the middle where the density doesn't change very much and acts as a barrier allowing little water movement between the two zones?

What is a pycnocline or transition zone?

500
This property describes tightness across the surface of water, caused by the polar molecules pulling on one another.
What is surface tension?
500

In the "Intro to density" lab, what did we create between the warm water on top and the cold water on bottom?

What is a thermocline?

500
