Instructions for using this template. Remember this is Jeopardy, so where I have written “Answer” this is the prompt the students will see, and where I have “Question” should be the student’s response. To enter your questions and answers, click once on the text on the slide, then highlight and just type over what’s there to replace it. If you hit Delete or Backspace, it sometimes makes the text box disappear. When clicking on the slide to move to the next appropriate slide, be sure you see the hand, not the arrow. (If you put your cursor over a text box, it will be an arrow and WILL NOT take you to the right location.)
Choose a category. You will be given the answer. You must give the correct question. Click to begin.

Water makes up this percentage of terrestrial organisms.
66%
Water makes up this percentage of marine organisms.
70-80%
The overall charge of water molecules
neutral
Unit of measurement for salinity (˚/◦◦).
ppt
Hydrogen bonds occur between these two types of atom (include charges).
positively charged hydrogen & negatively charged oxygen
This is responsible for many of the unique properties of water.
hydrogen bonds
This property of water refers to its ability to stick to other substances.
adhesion
Surface tension is caused by this property of water.
cohesion
This is the amount of energy required to raise a gram of a substance 1˚C.
specific heat
This unique characteristic of water creates a natural layer of insulation in cold climates.
less dense solid state
This is the driving force of winds.
differences in density
This diverts winds to the East and West.
Coriolis Effect
The percentage of ocean water involved in surface currents.
10%
Circular patterns of water currents caused by Coriolis Effect and shape of ocean basins.
gyre
Water current associated with the most amount of biological productivity.
Eastern boundary current
The generating force of most ocean waves.
wind
The part of a wave represented by its lowest point.
trough
These types of wave are another way of saying “wind generated”.
progressive waves
The distance used to determine whether a wave is a shallow water or deep water wave.
half a wavelength
The stuff in waves that is actually in motion.
energy
What force affects tides the most.
moon’s gravity
Another name for the highest point water gets.
high tide/high water
Only having one high tide and one low tide per day
diurnal

low tide
Angle formed by the moon, Earth and sun when neap tides occur
90˚
Zones of variation extend this deep below the surface of the water
1,000 meters
The density of water is affected mostly by these two factors.
temperature and salinity
Zone of dramatic increase in density
pycnocline
This is caused during winter in the poles when surface water cools and becomes more dense
vertical mixing
Approximate temperature below the thermocline
4˚ C
