This research aims to utilize local biodiversity specifically Sampunong Bolo Wild Life Sanctuary in Municipality of Sara, Iloilo, Philippines as teaching materials in K12 Basic Education Program Science Curriculum. The methods used were interview, photo and video elicitation, and document analysis. The highly diverse forest ecosystem in Sampunong Bolo Wild Life Sanctuary has a great potential as materials in teaching science in all grade levels according to science teachers in Northern Iloilo. They were very interested and willing to utilize local biodiversity in their places as teaching materials in science. They wanted to encourage Local Government Units (LGU) to help them create teaching materials like videos and pictures to be used in their teaching but they have a negative notion about accident happen in some educational trip in the past. All science teachers were able to create an activity title. They even identified in which part of the lesson these activities will be used. The results showed that local biodiversity can be integrated into teaching science. The use of localization and contextualization is an important approach to help learners enjoy science teaching and learning. Also, this study will educate not just students but also teachers that our local biodiversity is important and most of them are now dying. Teachers must take a move to protect and preserve our local resources.
