were formed by waves crashing against rocky coastline or coral reefs. Waves
can hit sea cliffs with blows averaging several hundred pounds per square
inch, which erode the soil and rock, and after many years create sea caves.
- In Scott O'Dell's Newbery Award-winning book Island of
the Blue Dolphins, 12-year-old Karana survives alone on an island
off California riddled with sea caves. Read this story with your class,
or read excerpts about Karana's exploration of the caves.
- Visit some of the sea cave Web sites below, including the Sea Lion
caves site. Ask your students to write their own fictional adventure
essays about exploring a sea cave. Each student should visit one or
more Web sites and record details about sea caves that they can include
in their stories. Encourage them to look for the answers to these questions:
How big is the sea cave?
What is the interior like? Is it always filled with water?
What life forms can be found there?
- When they are finished, choose one or more stories to make into a
play as a class project.
