Properties of Ocean Water
Make your own slide
• Pair up in groups of two to make your own
“Slide.” Read pages 194 and 195 and sum up
the important details in slide format like I do
up here everyday!
– Only have about 3-4 main ideas in short sentence
format
– Use the blank slide after this one to make record
your information
– You have 5 minutes, GO!

Review
• Hopefully this is a review . . .
o__________ - the ratio of the mass
to the volume
oThis is not weight! A large chunk of
lead and a small chunk of lead has
the __________ density!
Density of the Oceans
• Affected by __________ – dissolved solids add
mass
oSo more salinity = __________ density
• Affected by __________ – the colder the
ocean water is, the __________ it is.
• Where is the densest water found? What
makes it so dense?
o Answer: __________
