Carefully observe the teacher demonstration and in the space
provided below draw, color and label what you observe.
Explain what happened in the space provided below. Make
sure to talk about what the 2 different colors represent and
why you think the water with those colors behaved the way
it did.

1.
Take a look at the diagram above. Based on what you see, no matter the time of year, where does it seem the
Earth receives the most direct sunlight from the Sun?

2. What do you notice about the temperatures near the poles for both seasons?

Based on these observations, and the teacher demonstration, use the diagram above to show the movement of
ocean water.
Use red arrows to represent warm water
Use blue arrows to represent cool water
3. Now take a look at the arrows you drew.
a. What does the warm water seem to be doing?

b. What does the cool water seem to be doing?

4. In the space provided below, explain how convection currents move water in the ocean (*Hint: how does warm
and cool water move in our oceans?).
Here are some key terms you should try to include in your answer: Direct sunlight, indirect sunlight, poles,
equator, warm, cold, sink, rise
