Oceanography DR 2.1: “Earth’s Oceans” DR 2.2: “The Ocean Floor” Goal  Homework  Go over the Geology Unit Test. Brainstorm about the world’s oceans. The first 3 directed readings are all due by Friday: DR 2.1: “Earth’s Oceans” DR 2.2: “The Ocean Floor” DR 2.3: “Life in the Ocean”

Oceanography In your science journal  Goal  Homework  Go over the Geology Unit Test. Brainstorm about the world’s oceans. none Warm-up  In your science journal  Create a title page for Oceanography. Then… What is the difference between an ocean and a sea? (HINT  Geologically speaking, what’s at the bottom of an ocean?)

Ocean Temperature Goal  Homework  none Warm-up  Know how the water temperature changes with the ocean depth. none Warm-up  Grab your new Oceanography book from the cabinet. Read about temperature zones on p. 41 and look at Figure 5. Then, in your science journal  What are the three temperature zones of the ocean. Describe how the temperature changes the deeper you go.

Picture of the Day On Jan. 22, 1943 in Spearfish, South Dakota, the temperature fluctuated from a frigid -4°F up to 45°F in a matter of just two minutes. That's a temperature increase of 49 degrees! But that's not the end of this wild morning weather story. After the temperature climbed all the way to 54°F at 9 a.m., it crashed down again 58°F in 27 minutes to -4°F once again.
