Chapter 8, section 3
Ocean Water Properties
Lt: I can explain how nutrients are circulated through earth’s
oceans.
I.
Ocean salinity
A) Salinity- the
amount of salt dissolved in Water.
1. Average
ocean salinity =3.5%
B) Things that
change SALINITY
1. Precipitation=decreases
salinity
2. River
water=decreases salinity
3. Dry weather
(evaporation) = Increases salinity
C) Higher
salinity = higher ocean water density
II.
Other Properties
A) Gases
dissolved in ocean water – oxygen and carbon dioxide
1. Cold
weather can hold more dissolved oxygen than warm water
B) Buoys – used
to monitor oceans temperature and salinity
C) As you go
deeper in the ocean light decreases, temp. decreases, pressure increases
Then we viewed and discusses positive and negative aspects of Science projects.
Social Studies:
Life in the Trenches
World War I
LT: I can explain the poor conditions in the trenches for
solders during the WWI.
Then we did a station activity: Welcome to the Trenches
Mr. Grove checked the WWI Map Homework.
