  1. Earth Science Week 22 Oceans

  2. Monday Warm Up (117) • How do scientists know what the bottom of the ocean looks like?

  3. Ocean floor topography model • 2 cups flour • 2 cups salt • About 1 cup of water • Mix flour and salt in bowl. Make a well in center of dry mixture. Pour water into well. Knead until smooth and elastic and non-sticky dough is formed. • Shape into ball and place inside plastic baggy.

  4. Tuesday Warm Up (117) • Brainstorm features you might find on the ocean floor.

  5. Ocean floor topography model • See page 384-385. Include each feature on model: • Continental shelf • Continental slope • Continental rise • Abyssal plain • Mid ocean ridges • Rift valley • Seamounts • Ocean trenches

  6. Wednesday Warm Up (117) • Compare and contrast rift valleys and ocean trenches

  7. Label ocean topography models • See page 384-385 • Make flags of information in boxes and place them on your model with toothpicks. • Paint your model

  8. Thursday Warm Up (117) • Brainstorm a list of living things you might find in the ocean.

  9. Cornell notes: p. 388 - 393 • Plankton • Nekton • Benthos • Benthic environment • Intertidal zone • Sublittoral zone • Bathyal zone • Abyssal zone • Hadal zone • Pelagic environment • Neritic zone • Oceanic zone

  10. Friday Warm Up (117) • Compare and contrast plankton, nekton, and benthos.

  11. Cornell Notes p. 416 - 421 • Ocean currents • Surface currents • 3 factors that control surface currents • Global winds • Coriolis effect • Continental deflection • Deep currents • How do deep currents form (fig. 7) • How different temperatures and densities of water cause currents to move (fig. 8) • Color map with currents as shown on p. 419. Label each current.
