Lesson Plan
Sweet Potato, ‘Uala
Pauline Chinn
University of Hawaiʻi at Mānoa
Title: Sweet Potato, ‘Uala and Relatives (Family Convolvulaceae)
Grade: 4 or higher
Time: 2 hours without extension.
Standard 4: Life and Environmental Sciences: STRUCTURE AND FUNCTION IN
ORGANISMS: Understand the structures and functions of living organisms and how organisms can
be compared scientifically
To the Teacher: Connections to Place & Culture(s)
Through the activities in this lesson, students will explore and compare different structures and
functions of the sweet potato family composed of familiar native and introduced members that
range from culturally and economically valuable to invasive weeds.
Sweet potatoes,‘uala, were associated with Lono, god of planting and the demigod Kamapua‘a. A
broken sweet potato resembles a pig snout, leaves may remind one of a pig’s head (kukui, too), thus
were considered kinolau, body forms of Lono. ‘Uala could be grown in sunny, drier areas than kalo
in any soil but heavy clay. Though most food plants brought by Polynesian voyagers were
domesticated in Asia and the Western Pacific, genetic evidence indicates sweet potatoes were
domesticated in S. America. Family members including the sweet potato (above) have flowers that
look like morning glories. Beach morning glory, pohuehue; pāʻū-o-Hiʻiaka, skirt of Hiʻiaka, and
koali are native to Hawaiʻi. Introduced relatives include edible ung choi (swamp morning glory),
and decorative wood roses, morning glories, and a few weeds. The legendary menehune ate ʻuala
and made baskets from koali vines.
Materials: Sweet potatoes, cuttings, relatives growing in the community, ung choi from market.
