Each year we welcome over 2,500 students and staff from schools worldwide.

Piyawan Science Day
Aim: To explore the biodiversity of species at Piyawan whilst learning and performing different data collection methods.
Method: After completing an initial land use survey of the site, taking into account observations of the uses of the surrounding land, river and riparian zone students will undertake 4 scientific inquiries to investigate biodiversity and factors which affect biodiversity at Piyawan.
1: Insect Biodiversity- Using Sweep nets and pooters to collect invertebrate samples from 2 different areas of the resort. Identify species collected to Order using identification charts then compare biodiversity and species and richness of 2 different sites.
2. Bird Watching – Using binoculars and bird identification books record the diversity and abundance of the avian species present at Piyawan
3. Soil testing- Using a soil thermometer and pH and moisture probe collect data along a 50m line transect at 5m intervals. Complete manual soil texture survey to establish soil type along length of 50m line transect. At 0m, 25m and 50m intervals take soil samples and test levels of potassium, nitrogen and phosphate levels using chemical testing kit.
4. Water testing - Collect samples of river water and rice paddy water to test water quality. Investigate pollution levels using chemical tests for dissolved oxygen, nitrogen, phosphates, fecal coliform and biochemical oxygen demand. Students will also test water pH and temperature.
Results: Undertaking all four experiments students gained the opportunity to learn and practice several new data collection and testing methods.
Discussion: Students discussed results linking their investigations and findings back to the wider picture of what can effect local and global biodiversity, (e.g. land usage, pollution levels in soil and water) and the associated conservation issues with trying to balance the needs of humans with protecting and conserving habitats and biodiversity.
Conclusion: Despite the heat and busy program, students came away with a greater understanding of local and global biodiversity and conservation issues and gained experience with new types of scientific investigation.
