Materials & Setup
• Set up four information stations around the room using the “Information Station Graphics” (master, pp. 25-30) for three of them and vials of sand from Oneuli and Oneloa beaches for the fourth. (See class period one materials & setup below.)
Class Period One
• Small, labeled vials containing sand samples from Oneuli and Oneloa beaches (samples included with Activity #1, or instructions for collecting more in “Guidelines for Collecting Sand,” p. 8)
• “Information Station Graphics” (master, pp. 25-30)
For each student
• Student Page “Where Does the Sand Come From?” (pp. 31-32)
1) Hand out a copy of the Student Page “Where Does the Sand Come From?” to each student.
2) Have students visit the stations, transferring relevant information to their own maps, and answering the questions on the student page.
3) Near the end of class, discuss students’ hypotheses about where the sand that comprises Oneuli and Oneloa beaches originates, and what accounts for the differences in particle size and composition that they observed during Activity #1 “Sand Analysis Lab.”
• Find out the meaning of the Hawaiian names, Oneuli and Oneloa. Write a chant or poem, or draw a picture that illustrates where the sand from each of these beaches seems to originate and how it might be deposited on the beach.
