Enhancing 8th Grade Geology with Dell Axim X30 PDAs for Field Data Collection

At Kawananakoa Middle School, students utilized Dell Axim X30 PDAs in 2004 for hands-on geology projects during field trips to the Big Island. They measured lava toe and vesicles at Pu’u Huluhulu, gaining insight into volcanic gas presence and lava viscosity through vesicle shape. Students collected vital data such as length, width, and GPS location, which was beamed to a single device and uploaded for analysis. Additional activities included water chemistry testing on Kauai and Oahu, culminating in the creation of a mini-field guide and a rainforest simulation for ecosystem exploration.

  1. Kawananakoa Middle SchoolPDA Use PDA Use

  2. Dell Axim X30 • Received 12 Axim X30 pdas in 2004 • Used primarily for data collection activities on outer island field trips.

  3. (8th Grade) Big Island • Lava toe and vesicle measurements at Pu’u Huluhulu and near eruption site.

  4. Vesicles signify presence of gas in lava during cooling • Vesicle shape provides lava viscosity info http://z.about.com/d/geology/1/0/M/W/scoria500.jpg

  5. Measurements (length, width, vesicle shape, gps loc., etc…) collected and inputted into pdas • Data beamed to one pda and saved onto sd card

  6. Data uploaded onto Internet for further analysis upon returning to school

  7. (7th Grade) Other Activities • Water chemistry testing at Salt Pond Beach Park and Kokee stream in Kauai.

  8. Other testing sites included Pauoa and Nuuanu streams on Oahu • Data uploaded to UH database at www.hawaii.edu/environment

  9. Picture Viewer/Music Player • Mini field guide • Rainforest simulation in preparation for Alaka’i Swamp hike and Lyon Arboretum • Endemic bird songs
