AKS 3d: Ocean Properties
I can plan and carry out an investigation to determine the chemical and physical properties
(e.g., salinity, density, temperature, pressure) of ocean water
1. What do we already know about the ocean?
2. Imagine you are a diver in the ocean, what would you experience under water?
3. Watch the video clip: How does pressure change as we travel deeper into the ocean?
4. Analyze the Image: How Does the Ocean Temperature Change as You Travel
Deeper?
The temperature of ocean water decreases as depth
increases. The temperature of ocean water
decreases as depth increases.
However, this temperature change does not happen
gradually from the ocean’s surface to its bottom.
Water in the ocean can be divided into three layers
by temperature.
Explain how temperature changes as we travel
deeper into the ocean?
5. What does salinity mean?
6. Read and Summarize this:
7. What is Density?
8. Read and Summarize this: How does Density Change in the Ocean?
9. Evaluate: Answer the following questions
How does pressure change as we travel deeper into the Earth?
10. Explain the Arrows in this model
Temperature
Density
Water Movement
11. Explain the Arrows in this model
Temperature
Density
Water Movement
12. Analyze this Map: Which part of the world has the highest salinity levels?
13. Read and Summarize the Map: Why are some parts of the Earth have higher
salinity than others?
14. Draw Arrows to describe the ocean properties as we descend deeper into the Ocean:
Pressure
Temperature
Density
Salinity
