This article explores Pacific migration and offers scientific and technological explanations for a thousand year gap between settlements in West Polynesia and East Polynesia.
Scientists have used carbon dating on artefacts found throughout the Pacific to create a timeline of human migration. They think that most of West Polynesia (Vanuatu, New Caledonia, Fiji, Samoa and Tonga) were settled by 800 BC. After a long pause, settlers landed in the Cook Islands, Hawai’i, Rapa Nui and Aotearoa.
Computer modelling of wind direction and ocean currents suggests that changes to both of these things might have caused the gap in settlement times. Alternatively, some scientists believe the gap was due to the time it took for voyaging technology to change. Waka ama (outrigger canoes) were used for the earlier expeditions. The waka hourua (double-hulled canoe), which came later, could travel longer distances over rougher oceans and carry heavier loads.
This article supports the science capabilities use evidence and critique evidence – scientists need to use evidence to support their theories of what happened long ago.
Check your school library for the article from the 2019 level 3 Connected journal Shifting Views, download it as a Google slide presentation or order it from the Ministry of Education.
The teacher support material (TSM) can be downloaded from TKI (Word and PDF files). It has three learning activities – Waka voyaging, Science versus Disney and Archaeological adventures – along with resource links.
Navigating without instruments – introduction curates the Hub’s resources on Pacific navigation. It contains articles and activities about this ancient science.
Piecing it all together is an activity that promotes the skills of observation and inference when trying to solve a scientific problem through the use of evidence.
The article has a timeline of Pacific settlement. Timelines use written and visual components to convey information. The article Science over time curates Hub timelines that feature scientific ideas and heritage scientists. The article also provides pedagogical advice when using timelines.
