Deep, Deeper, Deepest:
The Ocean’s Depths
Activity: Students will learn the different levels
of the ocean’s depths, what makes each level
unique, and the life that can survive in each one.
- Ask students to imagine they are in a
submarine in the middle of the deep ocean.
They begin at the ocean’s surface and go
deeper and deeper. How would their view
out the submarine window change?
Would it get darker the deeper they go?
- Visit the Web sites below to learn about
different light zones scientists have identified
in the ocean. Have them draw and label a
diagram of the ocean’s light zones. How does
the temperature change in each zone?
Why does the temperature change? Where
do most of the plants and animals live?
Why do they live there?
- Help students put the different zone depths
into perspective. First, have them create a
bar graph comparing the heights of these
geographical and man-made structures:
- Empire State Building: 1,250 feet
- Statue of Liberty: 151 feet
- Mount Everest: 29,023 feet
|
How do these heights compare to the depths
of each light zone?
