Monday 1/26

Underwater Wonders pg 71
EQ: Compare & contrast continental with oceanic land forms?

Rubric:
1. Marking the text: Circle key words, highlight or underline main ideas, and write a level 1, 2, or 3 question for each paragraph.
2. Write in the the matching oceanic and continental land forms.
3. Complete the DLIQ summary




Tuesday 1/27

Rubber Duckies and Ocean Currents pg 73
EQ: Explain where the ocean currents took the rubber duckies?
Rubric:
1. Plot the points, connect the dots in order, and label the date
2. Answer questions 1 & 2

Rubber duck on beach

Introductory Discussion

  1. How does plastic get into the ocean?
  2. Where are most of the plastic things that we use made? How do they get to us in Canada?
  3. what happens if ships carrying plastic encounter storms and stormy seas?
  4. What happens to plastic once it gets into the ocean?
  5. Does it float or sink? Demo.
  6. Does it stick out of the water very far?
  7. Which might get blown by the wind more, something that sticks up out of the water, or something the floats just at the surface?
  8. Watch a piece of flat and a cup of plastic float in a shallow pan filled partly with water.
  9. Blow on the water. Observe which piece moves more under the influence of the wind.


  • Where do ocean currents coming from? Which ones are warm? Which ones are cold? Is the ocean water near us warm or cold?



  • Every ocean basin has a gyre, which is a circular pattern of currents flowing around and around.
  • The main gyres in the northern hemisphere flow clockwise and the main ones in the southern hemisphere flow counterclockwise.
  • We’ll also be looking at the Alaskan Gyre, which flows counterclockwise at higher latitude than the North Pacific Gyre.


Objectives
1. Plot latitude and longitude data on a map.
2. Learn the names of major ocean currents, where and in what directions they flow.
3. Analyze data from a rubber ducky spill to learn how the distribution of plastic pollution in the
ocean relates to ocean currents.

Methods:
Students will work in groups of 2.
1. Explore the adventure of rubber ducks (plastic pollution) that were spilled in the ocean.
a. Use Figure 2 to plot data (listed on handout, or write data on the board) of when and where
the rubber ducks were at different times. Label each data point with the corresponding date.
b. Connect the dots in order of time.
c. Show and discuss a map of global ocean currents (Figure 3).
d. Ask students to come up with a route (on Figure 3) by which the rubber ducks could have
reached the Atlantic Ocean by now. Ask for volunteers to show the class their route. Many,
many routes are possible, some very long, and one quite short

Rubber Ducky Spill!!!

In January of 1992, a ship carrying 29,000 plastic bath toys lost the toys at sea! Using the
data below, plot the path the bath toys followed on your map. Connect the dots in order.

Ocean Currents Around the World pg 74
EQ: Explain how the ocean currents move around the world
Rubric
1. Draw, label, and color the ocean currents and write the characteristic.
2. Complete prediction of the Indian Ocean. Draw, label, and color the currents and write the characteristic.
3. Complete the (DLIQ) summary. Do, Learn, Interesting, and Question.

What causes our ocean currents?

  1. Label on your map North Pacific (purple), South Pacific (green), North Atlantic (blue), South Atlantic (red)
  2. Pick out a current card and pencil in their locations on the Ocean Currents Around the World Map.
  3. Use a red color for a warm current and a blue color for a cold current.
  4. Turn the cards over and label the character of the current.
  5. Predict where the other currents are located.
  6. Lastly, finish up the rest of the three cards by passing them around in your group.
  7. Switch tables clock-wise till all 16 currents are done.
  8. Use what you have learned so far to pencil in the circulation pattern in the Indian Ocean with red and blue warm and cold currents.
  9. Complete the DLIQ summary. What did I do, learn, something interesting, and a question I have about ocean currents.
