| Unit: Intro/Water
Learner Objectives: The student will
1. Assess their own current knowledge of marine biology.
2. Identify turning points in the history of marine biology.
3. Define, currently, marine biology and explain why marine
biology is not a separate science but
a compilation of many fields of science.
4. Examine different methods of studying marine life.
5. Describe water molecules.
6. Explain properties of water (class and lit rev).
A. solvent
B. cohesive/adhesive
C. high specific heat
D. high boiling point
E. latent heat of evaporation
F. latent heat of freezing
G. viscosity
7. Describe seawater.
8. Define salinity.
9. List and give parts per thousand of the major constituents
of seawater.
Cl- 19 0/00
Na+ 10.6 0/00
SO4- 2.66 0/00
Mg+2 1.28 0/00
Ca+2 0.4 0/00
K+ 0.38 0/00
10. List the minor and some trace constituents of seawater.
Br, C, Sr, B, Si, F N, P, I, Fe
11. Describe methods of measuring salinity and identify the
method used to determine salinity in
class (record aquaria salinity).
A. refractive index
B. conductivity
C. chlorinity
D. density
12. Explain why it is possible to determine salinity based on
the chloride ion alone.
13. Identify the salinity of deep oceanic waters.
14. Compare O2 concentrations of the atmosphere
with water.
15. Identify the 3 factors which affect O2 of
water.
16. Explain why the aquaria need to be large compared w
freshwater aquaria and give
approximate size and weight of our
aquaria.
17. Identify the source(s) of water in our aquaria; compare
advantages and disadvantages of our
sources of water.
18. List some benthic zones and describe their boundaries.
19. Define transect.
