Eighty Students joined us for a one day trip at Wat Chalerm Prakiet Park, in Nonthaburi, for a day of exploring people, places and the Chao Phraya River itself. All students were heavily involved in four different activities throughout the day, facilitated by the barge team.

Science themes became hands-on experiences. Students were introduced to water quality monitoring using a series of water quality tests. They learned how to test and evaluate the water quality of samples taken from the Chao Phraya River. With the data collected, students looked for patterns and relationships between land-use and the behaviors which affect the quality of the river.

Students measured the flow rate of the Chao Phraya River. As the Barge departed from the pier, students tested the flow of the river using scientific tests. They then made conclusions about their findings through extensive discussion with staff and other students.

Students also explored water hyacinth, the plant that fills the Chao Phraya River, providing a home to macro invertebrates, which in turn provide an indicator of water quality. Students also discussed the history behind this invasive plant species arriving in Thailand.

The final activity explored the process of erosion and deposition throughout a river.  Students created a make shift stream on a stream table, introducing influencing factors and measuring the gradient and velocity. This process helped with the understanding of erosion and deposition in the real river.
