Objectives:1. Be able to name the main oceans of the world.
2. Explain the interaction between the ocean and atmosphere.
3. What is the composition of ocean water (pie chart)?
4. What is the average salinity of the ocean (what can make it change)?
5. What are the features of the ocean floor? (be able to model the ocean floor and label the features--topography)
6. What technology assists us in studying the ocean floor?
7. What resources are found in the oceans,, including energy resources?
8. How have human contributed to ocean pollution?
Describe what is being done to control ocean pollution.

BIG IDEA: The movement of ocean water is driven by differences in density and temperature, by wind, and by the moon’s gravity.
Vocabulary:
surface current, Gulf Stream, deep current, Coriolis Effect,
El Nino, upwelling,
crest, trough, wavelength, tsunamitides**, tidal range, high/low tide, spring/neap tidesObjectives:
1. Explain the causes of currents (surface and deep) and the factors that form/impact currents.--salinity, winds, earth's spin
2. How does water temperature and pressure vary in the ocean?*
3. Identify currents that have a significant impact on us (how do they affect climate?).
4. What are the causes/effects of El Nino (and La Nina)?
5. How do waves form and move? Explain the factors that impact
waves. (ex: bigger waves if wind blows for more time and atfaster speeds)
6. Be able to identify the parts of a wave. How do these parts relate to
wave movement?
