Riding The Currents

Marine

Unit 1 – Riding The Currents

Overview

For millions of years, plants and animals have been making their way to the Hawaiian Islands with the help of air and ocean currents. Beginning with the Polynesians who voyaged here, humans have been similarly assisted in reaching Hawai‘i. This unit engages students in exploring how marine life reached the Hawaiian Islands. Planning a course for a hypothetical Polynesian canoe voyage from the South Pacific to Hawai‘i provides a context in which students begin to understand the oceanic currents that helped determine the geographic origin of Hawaiian marine species.

Length of Entire Unit

Activities in this unit

  • #1 - Navigating the Currents

    Students plan a trip and course for a hypothetical Polynesian canoe voyage to learn some of the primary oceanic currents and wind patterns in the Pacific Ocean

  • #2 - Dispersing on the Currents

    Students learn about marine life reproduction and dispersal, and apply that knowledge to explain the dispersal of marine animals to Hawaiʻi.

Two class periods.

Unit Focus Questions

1. What major oceanic currents influence the origins of Hawaiian marine species?
2. How did marine life disperse throughout the Pacific Ocean?
3. How do origin, means of dispersal, and island location influence the species variety and rate of endemism among Hawaiian invertebrates?

Subject

Dispersal of marine life. Oceanic currents in the Pacific Ocean. Endemism.

Importance

As the Hawaiian Islands formed, marine life arrived here from other parts of the Pacific Ocean to become what we know as the native marine life of the islands. The ongoing dispersal of marine life depends upon ocean currents and the life cycle of marine organisms.

Enrichment Ideas

• Do Internet and library research to compile a collection of images of adult marine animals and the larval phases of the same species to provide a visual context for Activity #2 “Dispersing on the Currents.”

• Research the problem of marine debris in the Hawaiian Islands, analyzing the influence of oceanic currents on the origin of marine debris found here and the location of problem areas for marine debris on the islands.
