When you think about “Inquiry”what comes to mind?
Write a few thoughts on a card without your name.
You will pass in the card.
You will be asked to share what you’d like.

Ducks Ahoy!!!
Jan. 1992 – 29,000 plastic bath toys wash off of a ship in the Pacific near Int’l Dateline
Nov. 1992 – First recorded find of toys; six toys found on the southern coast of Alaska
Late 1990’s—Estimate of when toys passed Bering Straight and entered Arctic Ocean
Late 2001—Estimate of when toys entered Atlantic

Toys’ Route Over 5 Years
How did the toys move?
Which could lead to investigations about…• Floating and sinking• Ocean currents• Ocean winds• ???
Hmmm…
I was just thinking about ocean currents,and that led me to the question…
What makes ocean currents move?
Let’s Investigate!
• What do we know about ocean water?– If you were to go swimming in the ocean, what
might it feel like?– Would it matter where on Earth you were
swimming?– What would you need to think about to stay
safe as you swam in deeper water?
On Your World Map
Draw arrows to show the general flow of major ocean currents.
Write a few words, phrases or sentences to tell something you know about how and why ocean currents move.
By now, we’d expect students to have brought up…
• Differences in ocean water and fresh water, especially salinity.
• Differences in temperature based on geographic locations.
• Aspects of the ocean that cannot be seen easily, such as riptides.

Words, Phrases, Sentences
Explain
What do we know is happening?• Fluid (water is moving), but so is heat• Has to do with differences in heat• Has to do with differences in density
Convective Heat Transfer—The movement of heat due to the differences
that heat causes in the density of a fluid

So…
What makes ocean currents move?
How did the duckies end up exploring so far?
What else might be affected by ocean currents?

Create a Concept Map Ocean currents
Some Terms• Convective Heat
Transfer• Water temperature• Warm water• Cool water• Density• Floating• Sinking• Gyre
• What are two attributes of ocean currents you could put on your concept map?
• What are two examples of ocean currents or things that are affected by ocean currents that you can put on your concept map?
So what?Does it matter?

• Center for Marine Conservation has been coordinating coastal cleanups since 1986. The CMC keeps careful track of all the debris that is collected The CMC divides their data into debris found, listing the "dirty dozen"--twelve items found most frequently:
1) cigarette butts2) paper pieces3) plastic pieces4) styrofoam5) glass pieces6) plastic food bags7) plastic caps and lids8) metal beverage cans9) plastic straws10) glass beverage bottles11) plastic beverage bottles12) styrofoam cups

What were the parts of the lesson?
Was this inquiry? How do you know?
How could this be more like authentic inquiry?
